Refinishing Top Nail White Oak Floor in El Sobrante Richmond, CA Area

Even though I’ve been sanding and installing wood floors for a living for more than 23 years, I am still surprised at the look on people’s faces when I tell them we can save their floor and make it look like new again. The beauty of hardwood floors is that they are serviceable. They can be sanded over and over again and as we all see in the Bay Area, lots of them last more than a hundred years. 

This time our client wanted to know if their oak floors can be saved. After a quick site visit I assured here that with proper sanding, and some repairs we could bring that floor back to life. After we finished the project she actually told me she expected me to say she had to replace the entire floor. That’s what she had heard from others. 

Surely enough, after discussing price and schedule we started the work. Within a week we completed the sanding and some repairs. The client was out of town and I made sure to text her progress pictures and/or any questions I had. She knew exactly what we were doing every day and what the floor looked like at every stage. 

At first we stripped the finish off the floor to expose the wood itself. Walking around the home I took pictures of the dark stained areas that didn’t come out in the sanding. I sent the pics with cost for each area of repair. Upon approval we started replacing the white oak floor boards that were damaged. A lot of contractors make the mistake of putting in red oak in white oak floors, but not here. Everything is done properly and according to our industry guidelines of the National Wood Flooring Association.

The next step was to apply wood filler to all the nail holes and gaps. A few more passes with our dustless sanders and the floor was just about ready for the finish coats.

We use Bona HD Traffic for most of our floor sanding. It is durable and has a fast curing time. I do recommend that if you have small children and/or dogs to apply an extra coat. 

I did that in my home and it is a great investment. 

After completion of the sanding and finishing of three coats, we allowed the floor to cure for several days before our client could move back in. She later called us to do more work for her, and she couldn’t be happier.

Red Oak Floor Project – San Pablo CA

Our job was to add Red Oak floors in the dining living areas. The owner moved a wall to open up the main floor, and so we laced new floor boards into the existing. That is instead of going the easy way and butting it against the old floor. We started out by preparing the sub floor. That meant fixing any squeaks, repairing soft areas and sanding down the high spots. Afte that we vacuumed and put in a vapor retarder to slow down the moisture coming from the crawl space.

Matching the existing floor lines we then added floor row after row. Some had to be cut to fit into some areas, but most of the boards just slid into place with no problem. After nailing the entire floor we then let it acclimate in place, which means letting the floor reach its’ optimal moisture content for that area. While waiting for that to happen we then started refinishing the rest of the floors in the home. Using dust containment systems we virtually have no dust in the home while we are sanding. This leads to a clean job site, which then leads to a better sanded wood floor and a cleaner finish coat. After about a week of the new wood floor acclimating we then proceeded to finish the sanding on the new areas as well. We spend time setting any nail heads that were exposed and filling the floor with wood filler. The filler is applied as a continuous coat throughout the floor. We then sand it off until we are happy with the surface condition.

At the very end we use our hand scrapers and clean up corners and areas hard to reach. A thorough vacuum and mop and the floor was ready for the finish. This floor was coated with three coats of water base satin urethane by Bona. As you can see and to the delight of the home owner, the new floors blended in beautifully into the old.

Every floor is different and so every job is different. With most phases of the sanding process being the same, each floor dictates what we do or don’t do to make it look better. Even thought we’ve been in business since 2002 we never get bored with making floor look so pretty, especially when seeing the smiles on people’s faces.

Refinish and repair old oak floors or replace with new?

Save your money and restore your old hardwood floors

The question always arises: should I reuse what I have or buy a new floor? Right? New is exciting and fun because we get to shop around, make choices and get something that is – well; new! The thought of this is much more exciting than looking at what we have had for years, thinking how to make it better and more interesting. Hardwood floors are an asset and as such, should be looked at as a long term investment and not a temporary floor covering. These floors had been in service for more than a 100 years in a lot of homes.

Unfortunately, the craft of working with wood floors is slowly disappearing. The number of floor contractors who can tackle a really good sanding job is going down every year. If you have an old wood floor that has some blemishes, or even some boards are buckling – this floor can be sanded, repaired and finished to last you years to come. Then, you could use the money your saved on other things.

Let’s take this floor for example, an old top nail white oak floor. This floor was covered with different carpets over the years, had been urinated on by dogs, had carpet shampoo flood some areas and that’s just some of it. Well, most contractors that came to quote on that floor suggested a new floor instead of repairing and sanding the old. That is because they were not qualified to do such work.

We came in, repaired the floor where needed, added some new at the entry way and did our usual stain and finish to the highest standards.

The home owner was thrilled with the outcome, and was even happier to be able to spend his money on new furniture, instead of a new floor.

We mainly work in our immediate area which includes the 80 corridor from Oakland to Pinole, with more areas served like Lamorinda and walnut creek. We had spent the last 20 years restoring old floor, and installing new hardwood floors. Be certain that we will recommend the best option for you, not to our pocket.

Top Three Mistakes Consumers Make When Hiring a Floor Contractor

white oak refinish Berkeley bona ambersealWhen hiring someone to refinish your wood floors, or to install new hardwood floors there are many things you should do and don’t. From asking the right questions to checking the experience and quality of the company, this process of interviewing and hiring can be long and agonizing.

Here are my top three mistakes most of us do in the process of hiring a floor contractor. It could be for a refinish and repairs, or installation of new wood floors. The mistakes cover both avenues, and are mainly things I see here in the Bay Area, CA.

  1. Calculating a price by the square foot:
    A lot of consumers get stuck on this. Understand that this price per square foot didn’t come from contractors, it was created by someone along the way to put a price tag on something that isn’t a product – it’s a service. Professionals give you a quote for the work you ask them to do. They calculate in their quote things from payroll expenses to how much filler they need to use on your floor. A professional cannot simply take a number like $4 and multiply it by any size job to get them to a reasonable gross sale. When a professional gives you a quote, don’t automatically compare it to others just by dividing the number by the square feet you have. A lot more goes into your floors than you know, and even more than the professional has time to explain to you. I always refer to the dentist example. Understand that a tooth specialist could possibly charge thousands of dollars for 30 minutes of work. Compare that to when you get a crew of experienced craftsmen to work on your floors for a week, and it costs you only around 8K or 9K, it does seem cheap in comparison. To me, what society has determined is unquestionable as far as prices go, is beyond logical. It is unfair and makes no sense who gets to “get away” with their prices, and needs to negotiate, accommodate and follow.
  2. Asking google if whatever the contractor told you is actually true.
    Anything from what finish is to be used, or floor product. Understand that the information online is usually wrong, and doesn’t apply to your scenario. Trust in your reputable professional to provide you with the right answers, and recommend the right product. On the same token, don’t go to online forums seeking others opinions on your situation. They didn’t take the time to drive to your home, and give you their time. Finally, they don’t even know what the full scope of work is, and most likely they would like to look like they know better when in fact they usually don’t.
  3. Relying only on review websites
    It’s become a norm to check and judge companies based on their presence on review sites like Yelp or Angie’s List. Understand that as much as it is a good resource to read about other people’s experiences, those sites could also have bad information. These days it is easy for a new company to create a profile that looks like they had been around for decades, served hundreds of customers – when in fact – they have been in business for a few months. Writing fake reviews, and posting stolen pictures from social media is common among those companies. Unless you are in the trade of floors, you couldn’t tell just by looking at their profile. Beware, as to how you should take those sites with a grain of salt.

Repairing, Sanding and Finishing a 100 Year Old Floor

Repairing, sanding and finishing a 100 year old floor can be challenging to most, sometimes even to the best of contractors. The unknowns of things like wood species, install technique and finish types can add up pretty quickly into a big challenge to match.

In this blog I will walk you through a job we just completed in Piedmont, California. The floor was a solid parquet with stain and original finish on it. We had to sand, stain, repair and finish it with our modern tools and finishes. Read more

Hardwood Floor Installation Disaster

We got a call from a reputable contractor to fix a newly installed white oak floor in Berkeley, CA. When I showed up to look at the floor, it was already cupping and separating from the sub floor. There were multiple humps a couple of inches high, and this oak floor needed to be replaced. The hardwood floor was in place for less than a month, and was part of a kitchen remodel.

I checked the moisture content in the floor and the sub floor, visually inspected the crawl space and tested the floor for proper nailing schedule. All of my tests came at a big fail for each category. The moisture level was too high in both the floor and the sub floor, the heat was off in the house, the fasteners were the wrong gauge and the floor was the wrong type. Evidently, the owner and the contractor knew of the moisture issues and flooded crawl space, and didn’t think it would have any effect on the new floor, since there are wood floors throughout the home already.

Everyone wants to save money, and it is just fine and perfectly understood. Saving money on installation of new wood floors isn’t smart. Wood moves at all times. Every time the relative humidity changes – wood moves. It is only in the hands of a true floor professional to decide which floor is best suited for your home. Read more

Top Five Complaints and how to Avoid Them

If you are a professional hardwood flooring contractor like me, installing wood floors becomes a second nature. From the preparation to the final product – it is a careful step by step process. Done right, it can yield a floor that can last more than a 100 years. It sounds so easy just reading about floor installation or watching a video on YouTube. So why are there so many problems in reality? Because installing a wood floor is not that easy. Every day home owners pay a good amount of money for so called professionals to install their floors, only to have a problem floor shortly after.

The most common complaints are:

  1. Cupping – that is when the edges of each floor plank are raised. A Simple solution to that is knowing your moisture content and relative humidity levels inside the home and the wood before, during and after installation. Many installers skip this step or don’t understand it. The fact is that any wood can be installed successfully in most situations. A simple check with a moisture meter and allowing time in the schedule for acclimation can prevent most of the cupping complaints.
  1. Gaps – whereas cupping is the result of the wood gaining moisture, gaps is the opposite. When gaps appear in the floor, it is an indication that the floor lost moisture. That means again that acclimation and/or living conditions were not met when installation took place. Gaps also happen during the winter season when dry heat from the home furnace dries the air and causes shrinkage in the wood floor.
  1. Squeaks – the floor look flat but makes a lot of noise. One common reason is a bad nailing technique combined with the wrong nailer and fastener gauge. Another reason could be poor milling of the wood. Either way, the installer should have noticed the issue before completing the entire floor. Another possible reason is that the sub floor has a lot of deflection so with every step the wood moves and in turn makes a squeaky sound.
  1. Appearance – with every flooring product the manufacturer usually allows for up to 5% of material to be out of grade. That means that in worst scenario every box of flooring will have 5% of flooring material that can’t be used or would not look so good with the rest of the floor. It is fair to say that in most cases the floor planks are pretty consistent and don’t actually have that much waste in each box. Nonetheless, when installing a floor it is good practice to mix up the boxes and communicate to the home owner what the material looks like. I’ve seen many who went to local showroom and looked at a small sample without being told that the actual floor would look much different. There will always be the dark board and the light board in the floor. It is a natural product, but when some planks look like they truly don’t belong – it is a problem.
  1. Transitions – doorways with really big and bulky thresholds or sliding doors with not so beautiful moldings. It is all in the details, that is what I was taught. The floor could like great but when the final touches are not crisp and pretty it can really ruin the overall “feel” of the install quality. Taking the time to plan out those details can pay off big time when the job is done.

At Avi’s Hardwood Floors we work hard to make sure every client is truly happy for years to come. This takes a lot of educating you the client and open lines of communication throughout your project. As it is impossible to make each floor perfect, we get pretty darn close to it every time.

Hiring a Professional to Sand and Finish Your Hardwood Floors – Understand What You Pay For

Here at Avi’s Hardwood Floors we specialize in installing, sanding and finishing wood floors. That is all we do, every day five days a week all year. One client said to me recently that he did not appreciate the full art and effort it took to refinish a floor until he saw us in action.

These days it seems most flooring products in the market are part of a trend of colors like gray and white. These floors are mostly engineered and often wire brushed which means – you cannot refinish them in the future. The art of sanding and finishing is slowly disappearing as the need for craftsmanship is declining. The market is filled with more people who can only install floors at a simple straight layout, yet alone add borders or set inlays and medallions.

The art of sanding and finishing is more appreciated now than ever, as home owners who have solid wood floors start searching for someone to refinish their wood floors, they often times find it hard to find someone qualified to do the job. Most guys have not had any training in refinishing floors or simply cannot do it.

When you find and hire a professional to refinish your floors understand the following:

  • Refinishing floors is an art. Even with all the training and years of experience it is still all in the hands of the craftsman or woman
  • Every job is different so the professional is challenged with each floor in different ways
  • The task of reviving an old floor is a multi-step process, unlike what you might see on your local home channel. It is a time consuming process
  • True professionals who know their craft have been around for a while and would still be around for years to come
  • Putting a price per square foot on this type of labor is simplifying the idea that anyone can do it and provide the same result
  • Refinishing wood floors takes a lot of attention to detail, for example: protecting adjacent surfaces, owning the right machines to provide complete dust free sanding, mastering the technique for each wood specie, knowing what to use for filling oak vs. cherry, how to treat a top nail floor vs. tongue and groove, identifying and repairing a floor, choosing the right finish for the client and being able to master the use of each finish.

As you can see, sanding and finishing wood floors is truly an art. It cannot simply be taught by attending one school, watching a video or reading a book alone. It is a process of years of learning and with each wood floor comes a new challenge. Next time you look for someone to refinish your wood floor understand that not all who say they can – can do it well.

How We Contain Wood Dust

Hardwood-Floor-Kitchen-White-CabinetsAt Avi’s Hardwood Floors we use several ways to control the cleanliness of your home while we sand and finish your wood floors.

We start with a clean site. Normally we would vacuum the floors and spend time taping off areas of the home where we don’t work. If we work in kitchen area we tape off all cabinets and if you have a big tv and wall mount speakers we will tape them off as well.

We use state of the art sanding machines – these machines are expensive industrial type sanders that are specifically designed for wood sanding. These sanders are the only ones in the world tested for wood dust emissions and are the most efficient in dust containment. Sounds like magic, right? Not really. We have seen other contractors claim to be dust free when in fact all they have is an old sander with a cheap utility vacuum attached to it. A vacuum sucks in the air and blows out air. If the vacuum is not designed to capture and contain the fine particles of dust then that dust will end up back in the air.

Some of our sanders have built in dust containment systems. All we have to do is empty the bags outside when they are full. Some of our other sanders are part of a dust free sanding system so all the vacuums are interchangeable and all the filters are HEPA filters. HEPA is the most efficient filter (and most expensive) in collecting fine dust.

Of course, there is always a few dust particles that get away and end up on the baseboards or in the corners. The last step of refinishing your floors is vacuuming every inch of the floors, window cells and other areas. We thoroughly check the site for any dust and wipe off any surfaces like counter tops.


The results yield a clean home with a newly refinished floor and a clean top coat of finish with no debris or dust stuck in it. At Avi’s Hardwood Floors we have done hundreds of jobs for families that had members of the family with allergies or other health conditions. We even did a few jobs for some with severe dust allergies. Those home owners had such strong reactions to dust they had specialty air cleaning systems installed in their home. Hiring us was the sure thing to do and we never disappointed anyone with our promise for a clean sanding job.

One client insisted we taped off their entire living room before we started work. We did. He came to check up on us a few hours into the refinishing process and said: “wow, there really isn’t any dust!” we just smiled and kept on sanding.

Trust us in doing a great job while keeping your home clean. This is not one of those empty marketing promises, it is the truth.

How do we create wood dust and why does it get everywhere?

We use several kinds of sanding machines:
20161230_094503

  • Belt sanders – the abrasive is a belt which spins around a drum in one direction
  • Single disc sanders – the abrasive is round and spins in one direction
  • Multi disc sanders – three discs which spin in multiple directions
  • Orbital sanders – single disc random orbit type

The one thing that is common to all these machines is this: they all create very fine dust quickly. Unless there is a vacuum there to contain the dust, it will get in the air immediately. The motor parts and fans inside the sanders help blow the dust off the floor and up into the air. Once in the air, the dust will travel several feet and often far enough into other rooms. It takes several hours for fine wood dust to settle on flat surfaces like shelves and floor coverings.

A big part of our business is fixing other people’s sanding jobs. We have seen dust on walls, in bedrooms all over the home owners stereo and tv. We have seen dust completely covering a furnace air return and piles of it inside floor heat registers. Dust must be contained for a good sanding job.
