Can I Refinish My Engineered Wood Floors?

in , , , , , , , , , , /by

Engineered hand scraped floorsWe were recently hired to install an engineered wood floor over a concrete slab in Danville, CA. This job involved a complete tear out of carpets and tile floor coverings, minor leveling and a moisture barrier installation prior to the floors being installed. The product itself was a hand scraped floor with a factory finish. That meant a few things:

  • This product could not be refinished in the future
  • This floor could only be cleaned and recoated
  • You could not change the texture or the color of the floor in the future

Home owners who choose pre finished wood flooring products are usually not aware of the consequences of their decisions. Meaning, some don’t realize that their floors could not be refinished in the future, or even worse could not be recoated. That meant in some cases that the floors would have to be replaced within five to ten years of install.

Solid floors - Can be refinished many times

When we installed this hand scraped engineered floors in Danville we took the time to educate our customer of the future options for the floor. We told them that these floors could not be re scraped or refinished. The only thing that could possibly be done is a buff and recoat.

I recently visited a home in San Anselmo, CA that had the same product installed by another company. The only issue the home owners had with the floor was the color. They were never told at the point of sale that their floors could be recoated because of a unique additive to the finish which was applied in the factory. In that case, they were stuck with a floor that would definitely need to be replaced in a few years.

When investing your money in a new hardwood floor make sure your product is versatile. Talk to the person selling you the hardwood floor about what can be done in the future in regards to refinishing your floors. Engineered floors don’t come cheap and hand scraped engineered floors are even more expensive, so when you invest a good amount of money in a new hardwood floors make sure you can service that product in years to come and not have to completely replace it after the finish started wearing off.

How Moisture Affects Wood Floors Part 2

Proper installation of wood floors requires a certain time for acclimation of the product prior to installation. It means that the wood needs to be stored inside the home under living conditions until it is in equilibrium with its surroundings. What does it mean? It means that the wood no longer gains or loses moisture. It is in balance with the home conditions, if you will. Let’s say that Avi’s Hardwood Floors is delivering solid white oak floors to Berkeley, CA. The white oak floor usually comes at around 7% moisture content. We know this from years of testing wood floors with our moisture meters. We also know that the average sub floors in the Bay Area range at 9%-12% in most places. That means that a wood floors needs to gain moisture before they are installed. An average oak floor in our area gains about one percentage point a week, so the white oak floors would need to be acclimated for about two to three weeks in total. What happens if you don’t acclimate your wood floor? The floor will gain that moisture after the installation and at that time, it has nowhere to go but up. That is when you see hardwood floors cup and buckle. How in the world do you add so many weeks to your remodeling project just for the floor and without delaying other trades at work? Avi’s Hardwood Floors has the answer.

  • We typically deliver the floor to the home a week or two before the installation and store it out of the way. For example, along a wall or behind a big couch. That way you can still maintain your life without interruption.
  • We recommend acclimating the floor to the house after it is installed and before it is sanded and finished. We coordinate with other trades like painters to come in during that acclimation time to finish up their work. This way the owner doesn’t “lose” precious time just waiting for the floor to acclimate with no other work taking place. 

By the time we get to finish the floors, they already reached the moisture content required. Acclimation is subjective to each home, each wood specie and each installation application. A home without air conditioning up in the Berkeley Hills has different conditions than a home in Lafayette. A red oak floor 3/4” thick will require different acclimation time than a solid Brazilian Cherry floor. A glue down of engineered wood floor will require different acclimation than a wood floor to be nailed down onto the second floor of the home.

In the end it is up to the wood flooring expert to determine the schedule of acclimation. Ensuring a successful installation is a must. If things go wrong and they do, the consequences are dire and expensive. In a failed floor installation like buckling, the floor needs to be replaced. That means additional costs:

  1. Moving out of your home
  2. Moving the furniture
  3. Removing trim and floors
  4. Identifying and fixing the moisture source
  5. New floors
  6. New trim
  7. Moving furniture back 

This is nothing compared to the trouble in time and mental energy wasted with having to deal with what happened, who would take responsibility for it and doing it all over again. When hiring a wood floor professional care to weigh your options carefully. Paying a qualified professional more money now is better than paying them a LOT more money later to fix a problem. 

How moisture affects your hardwood floors Part 1

Floor glued down to a concrete slab. Knowing that we applied epoxy moisture barrier first ensured our client a piece of mind. This floor will last a life time. Hardwood floors are a living product. They move when relative humidity changes, they change color over time and they present more character as time goes by. Hardwood floors is the top choice when it comes to floors. No matter where you go in the Bay Area, California you will find wood floors in almost every home. It is in homes in Pinole, El Cerrito, Berkeley, Albany, Orinda, Lafayette and the list goes on. The wood floors vary from red oak to white oak in most cases. Some are maple, walnut and hickory. Some wood floors are top nailed and some are tongue and groove thicker floors. The one thing that is common to all homes is the presence of moisture. It doesn’t matter if you live closer to the bay, or farther out into the Walnut Creek and Clayton areas. Moisture affects wood floors every day. It can get inside your home in many different ways. The most common ways moisture affects your hardwood floors are:

  • Air
  • Ground below in the crawl space
  • Concrete slab
  • Water leaks

We have all seen our wood floors exhibit movement between summer and winter. Lately with the drought in California; floors, sub floors and wood material in homes have shrunk more than the usual. As a wood flooring contractor I’ve been called many times to fix buckled and cupped floors. As a wood flooring inspector I have seen too many installation related failures as a result of excess moisture. The moisture from below like the soil in your crawl space and the concrete slab is there at all times. During the rainy season that moisture level is elevated. You don’t need to see water to determine a moisture problem. Wood flooring professionals measure moisture and relative humidity in different ways. Most tests are being done with moisture meters and relative humidity test kits. When hardwood floors are installed they must be acclimated first. Acclimation has nothing to do with time. It can last as long as weeks or as little as days. Wood floors are kiln dried to an average of 6%-9% moisture content. Our conditions in the Bay Area average between 9%-12%. Usually wood floors will need to gain moisture and expand before they are installed. When the floors are in nested bundles acclimating inside the house, it is easy for each board to move. If the floors are installed and then have to gain moisture and expand the result is cupping. Cupping will usually occur when there is a moisture imbalance in each board. When a floor board has no place to expand sideways, it is pushed upwards. That is why the edges are higher in each board and it looks like cupping. So, it is crucial that the wood floors are acclimated before installation. Every home is different. Some home owners have heat only, some have heat and air conditioning, some like it cold, some hot, some open the windows all day and some don’t. That is why professionals use moisture meters to determine the time needed for the wood to acclimate. Once acclimated the floors can be installed.

It is important to understand that the acclimation process is different for each wood specie and for each different product. For example, a 3/4” x 7” wide solid white oak floor would need different acclimation than a 1/2” x 3” engineered floor. It is up to the flooring professional to determine the appropriate acclimation time.

In most homes with crawl space the soil is damp year round. Some homes even get standing water during the winter months. A common solution to this problem is covering the soil with a moisture barrier. In other cases a sump pump is installed to remove the water from underneath the house, or I should say from underneath the wood floors. All that dampness and vapor go up into the sub floor and then into the wood floors. That is when the floors start to cup. I’ve heard many stories from home owners who had their wood floors installed during the summer, but it only until winter came that their wood floors started cupping (not floors that we installed, just to be clear).

Ensuring moisture barriers are in place is part of the job. It costs more money upfront but the alternative, which is a floor replacement costs a lot more. Nobody likes spending the holiday season dealing with a construction problem in their home like a failing wood floor.

Common Questions About Hardwood Floors

  1. Hardwood Floor RefinishHow long will the finish on my wood floors last?This is probably the most asked question when it comes to wood floors. Most urethane finishes would last you years to come. The question is how many years. If you hired a professional to do your floors, they used a commercial grade finish and applied the correct amount of coats on your hardwood floor. Nobody wants to pay for a refinish service, move out of the house and then have to do it all over again after three years. I did see this happen before. Usually when someone applied very thin coats of finish and used a cheap product. In most cases, with proper wood floor maintenance a floor finish should last anywhere between five and ten years. That is not to say that it would look as new after years. Finish gradually loses sheen and using the wood floors gradually wears the resin off the floor. I recommend that before you lose too much finish call a professional to apply one more coat of urethane on your hardwood floors.
  2. What is the best hardwood floor? We often get calls from home owners who have busy lives. They have families, pets, work and they don’t have much time to maintain their wood floors. Some of them want the hardest wood floor or the hardest finish. Some want wood floors that never scratch or dent. There is no such thing. With the explosion of exotic and composite products into the flooring market, consumers have started questioning the durability of our domestic products like Oak and Maple floors. Consumers were now familiar with the Janka Hardness scale, which is there to give you a reference as to how hard and dense a wood is. Numbers from a lab test are great for reference but when you drop a pot on your wood floors, it doesn’t matter if it white oak or Brazilian cherry – the two would dent. If your child drags a chair or a toy across the floor, the wood would scratch no matter what finish you have on the hardwood. Most importantly one needs to understand that it is the combination of wood type and floor finish that makes a good product. Top this with proper maintenance and you have the best wood floor. For example, having a really hard wood like Ipe’ is great, but if your contractor applied two coats of cheap urethane over it then your floor would look pretty bad and worn out in no time.

     

  3. How much should I pay for new hardwood floors?We all know that we want the most for the least amount of money. We also know that you get what you pay for. Interviewing several reputable licensed contractors can help you understand the scope of work. The right professionals can shed light on what they do to assure a successful installation. The most common problem people have with wood floors is cupping. A new floors is put in, the home owners move in and shortly after the floor is cupped. Now that the entire family is moved in, including furniture the solution is a big head ach. In our trade we say that there is never time to do thing right in the first place, but there is always time to do it again. Fixing a wood floor costs five times more than doing right the first time. So how much should you pay? In the Bay Area, California expect the prices per square foot to be a minimum of $4 for refinish and a minimum of $5 for installation services.

Ten Tips for Choosing New Hardwood Floors

in , , , , , , /by

HardwoodFloorIstallation_BeforeAfterAlmost every home in the Bay Area, California from the Berkeley Hills to Walnut Creek have hardwood floors. Once perceived as the expensive alternative to carpets and linoleum, is no longer expensive. Scientific data now shows that money is no longer the only consideration for choosing wood floors. Factors like health and effects on our environment play a big role in consumers decision making. Hardwood floors have become the go to floors. They are beautiful, renewable, easy to maintain and more affordable than ever. Here are the best tips for how to choose a hardwood floor for you home:

  1. Not toxic – unlike other floor coverings such as carpets and linoleum, wood floors are not made of synthetics and chemicals. The tree is cut and milled into wood flooring planks. Then in most cases the floor is finished in your house by a professional. Carpets and other floor coverings hide a lot of pollutants underneath them. A lot of people especially young children will develop some sort of health conditions living with those floor coverings over their life time. See this article from the American Lung Association http://www.lung.org/healthy-air/home/resources/carpets.html
  2. Easy to clean – hardwood floors need vacuuming, sweeping or mopping periodically. That is it. Once clean they hold no pollutants in them. Nobody likes hiring and paying professionals to come in and clean their floors. Unlike carpets which need constant shampooing wood floors are easy to maintain.
  3. This 80 year old floor was repaired and refinished by Avi's Hardwood FloorsNot expensive – years ago wood floors were considered a high end choice and very expensive. With today’s growing demand hardwood floors had become the number one growing floor choice by home owners. Whether bamboo floors or exotic Brazilian cherry, wood floors are no longer just for the wealthy.
  4. Durability – nothing compares to the durability of wood floors. Carpets will stain, smell and look just plain bad after a short period of time, especially if you have a busy life with kids and pets in the house. Wood floors are more forgiving, maintain their look much longer and can be refinished multiple times.
  5. Longevity – hardwood floors which were installed a hundred years ago are still being sanded and repairs to date. Carpets and other man made floor coverings never last that long. Nobody wants to spend a lot of money every few years on a new floor. That is why wood is the best choice.
  6. Trends – wood floors never went out of style. Designers and architects still specify wood floors as the go to floor. You can change the look of wood floors by changing the stain color after a while and keep up with the trends in the market.
  7. Easy to repair – if you have damages in your wood floors or need to add on a small section it is easy as easy can get. Many old wood floors have been refinished and repairs to revive their looks. Other floor coverings would have had to be torn up and replaced.
  8. Smart investment – any realtor will tell you that a home with wood floors is worth a lot more than a home without. If you installed hardwood floors at your home and years later wanted to sell it, you are most likely to get your money back and still make a profit on top of that. Homes with wood floors sell faster and receive many more offers.
  9. Better for our planet – we were all taught that cutting trees is wrong. Well, not quite true. With engineers controlling the forest harvesting, we now have more trees in our forests than ever before. The United States is not clear cutting forests and we are now able to manage them instead of eliminating them. With programs for planting trees and protecting wild life we manage to use wood, our most valuable resource of all with the least impact on our environment.
  10. Nothing makes a home more welcoming and warm than wood floors. With just a simple layout or an intricate parquet with inlays and medallions, wood floors make every house a special home to you and your family.
