Sand and finishing hardwood floors takes a tremendous amount of skill, patience and know how to continuously turn out high quality work.  On average, our wood floor contractors will refinish over 130 floors per year.  It doesn't matter if your hardwood floors are red oak, white oak, maple, Santos mahogany or Brazilian cherry.  National Floors has sanded them all.  Leave it to us to restore your hardwood.

How to determine if you can Refinish Hardwood floors

Before the work can begin, we need to find out what type of floor you have (Step 1).  If you don't know, then take a close up snapshot, from about 2 ft. away, with your smart phone and text it to (510)468-4165.  By determining the type of hardwood floors that you have, we can then discuss your options.  (Step 2) Secondly, we will need the "Total" square footage of your project.  At this point, we can start the estimation process on how much it costs to refinish your hardwood floors. 

There is a chance the floors are NOT solid.  The easiest way to detect whether or not your hardwood floors are solid is to access the heater vent or register in your floor.  If you have a vent in your floor, then you have a wooden subfloor.  You can then look at the profile of the floor to which type you have.  Typically, we can break your hardwood floors down into 2 categories; Solid hardwood or engineered hardwood. 

Do I have Solid Hardwood Floors? 

Vent removal exposes hardwood floor

If you have a heater vent in the floor, discovering your hardwood floors is easy.  Just lift the vent and take a look at the profile of the floor.  In this example, the hardwood floor is 3/4" solid hardwood floor.  If you're not sure, you can always text a picture of the profile to (510) 468-4165 and we can make that determination.    

Beveled Edge Hardwood floors

micro bevel hardwood floor national floorsThe example on the right is "Beveled hardwood floors".  Bevelved floors have a "V shaped" groove in them.  They can be either "Micro bevel" or just "Beveled", which is a larger bevel.  The bevel happens where the joints meet.  Sometimes it's on the long side of the floor boards or all four sides.  Beveled floors can be purchased in both "Prefinished" or "Finished on site".    

Regardless of whether your floors are prefinished or finished on site, National Floors can sand and restore them to a like new state.  What's important to understand is that when any beveled hardwood floor is sanded, the bevel will shrink or disapear all together.  This is determined by a few different factors; the condition of the floor, the size of the bevel and if there is any slope in the sub-floor.  When it comes to the larger bevels, the floor sanding machine cannot reach into the groove.  Any restoration of the larger grooves must be done by hand scrapping and unfortunately, there is an upcharge.  In over 90% of the projects we have completed, the homeowner decided it was not necessary to move in that direction.         

Sanding Solid Hardwood Floors

Type 1 is a "Solid Hardwood" floor.  This would be a premium hardwood floor that is usually installed over a wooden sub-floor.  These solid hardwood floors can be sanded many times due to their thickness.  What does that mean to you?  It basically means the floors can be restored to a "Like New" state many times.  Some solid hardwood floors are of course thick than others, but even the thinnest of the solid hardwood floor will have a very long life.

Sanding Engineered Hardwood Floorsengineered hardwood floor wear layerClick to Enlarge

The second type of hardwood floor is "Engineered hardwood" floor.  This type of floor is NOT a solid hardwood floor.  An engineered hardwood floor is designed to be installed over a concrete slab.  This type of hardwood floor usually has 3-5 base layers intended to keep the top layer or Wear Layer protected from the moisture present in all concrete slabs.  There are a few ways of determining whether or not your engineered hardwood floors are a candidate for a sand and finish project.  The easiest way is to posses a loose or extra board from the installation.  At that point, you can put a nickel on top and take a picture of the "Profile" or side view.  You can then text it to us so we can see if the wear layer is thick enough to sand.  Many times over the years, we have had homeowners tell us that the person who sold them the engineered hardwood floors said that the floors can be automatically be sanded up to 3 times.  This is a sales pitch from a person who has NEVER performed the work.  Sand and finishing engineered hardwood floors is always done with caution.  Only a solid floor can be sanded without care and risk of burning through the wear layer.  The picture on the right depicts the proper way to photograph the nickel on top of the engineered hardwood floor to determine the wear layer.     

The Process of Sanding Hardwood floors

  • Step 1 is to remove the old finish and "Flatten" your wood floors.  Worn out wooden floors tend to change shape in time and thus looses its flatness.  If you get down on your hands and knees and rub your hand across your floor, you will feel the unevenness and micro-bevels first hand.  We would then add "Wood filler" to fill in the hairline cracks for a better appearance.  After sanding the floor, 4-5 times, you will be left with a "New" surface.  Those old floors will look amazing, but they are actually very fragile and need protecting.       
  • Step 2 would be to decide the color.  There are 2 Options (Natural or Stain) 
  • Step 3 is to apply 3 coats of commercial grade finish.  This finish or polyurethane cannot be purchased over the counter.  You need a contractors license to purchase.  This is the same high quality finish that is used in businesses and malls.  If you have oak floors, like in the picture to the right, the "Natural" look will result in a golden tone.  If you prefer any other color, then you will need to have your hardwood floors stained.  With oak hardwood, you can go in any direction.  There are literally dozens of colors to choose from.    

You should know, not all hardwoods can be stained, but most can. Don't worry about the technical aspect, we got this. We will take your old hardwood floors in Alameda County and make them look like "New" again. What can you expect after the work is done? Floors that are flat, color that is even and a sheen of your choice.

Refinishing hardwood floor cost

The cost for refinishing hardwood floors is based off a few questions.  Please have the answers to these questions prior to calling:

  1. Providing National Floors with a close up, snapshot of your hardwood floors.  You can text to (510) 468-4165 
  2. The "Total" square footage (length x width) of the project.  Example: 10'x10' room =100 sq ft.    
  3. Choosing a Color 

If you provide us with these answers, we can more than likely quote you over the phone. 

You should know that the more square footage you have, the better the price.  Even the smallest job will require a 2-3 day service.  There are many variables for us to consider before we can give you an accurate cost for refinishing hardwood floors. This is why it is best to have an estimator come to your home and give you a quote.  It's free, without obligation and takes about 10-15 minutes of your time.  Just so you know, the typical cost for refinishing hardwood floors is much cheaper than installing new carpet.  Please feel free to call us and perhaps we can give you a rough quote over the phone.

DIY Refinishing hardwood floors 

Do not use orbital sander on hardwood floors illustration National floors

If you choose to sand and finish your own hardwood floors, be warned.  This is by far the most home improvement project you could tackle.  The rental tools on the left are commonly rented out with the misconception anyone can sand a hardwood floor.  These machines are too weak for the initial sanding process because they are "Finishing sanders" (finishing sanders are used in the very last step of sanding hardwood floors and definitely not in the beginning stages of sanding).  If you take a good look at the pic on the right, you can see the darker areas or low points the orbital sander missed in the roughing stage.  The DIY homeowner spent hours in attempting to flatten the floors and remove the old finish.  He was unsuccessful and eventually called us to finish the job.

A DIY person can NEVER accomplish the high quality hardwood floors that National Floors produces on a daily basis.     

NEVER Hire the Cheapest Contractor

If you think shopping for the cheapest contractor is saving you money, you're wrong and I'll tell you why.  Like oil and water, rock bottom prices and quality work don't mix.  Common sense will tell you that if a contractors price is cheap, it's cheap for many reasons that cause major regrets and headaches down the line. 

  1. The first thing that comes to mind is that the cheap contractor is "Illegitimate".  This is typically someone who works under the radar and is not licensed(by the CSLB), insured or bonded for your protection.  It's a safe bet that their work is inferior and won't meet the professional standard you are expecting when paying for a professional service.  That's especially a big deal if things go south on your project.  Contractor nightmares are a daily experience for people skimping on cost.    
  2. Secondly, bottom of the barrel pricing is a desperate attempt at getting the work.  Any contractor that produces quality work will be in demand.  It's that simple.  
  3. Thirdly, the products and materials the cheap contractor uses are low grade.  The products we use can only be purchased by a licensed contractor.  That means you can't go to the Home Depot for flooring contractor grade materials because they don't sell them.  If inferior products are used, the durability is weak and the life span of the floors is shorter.  That means you will have refinish your hardwood floors all over again in just a few years.        

On the contrary, like in any industry, a contractor that produces high quality work will "Not" work for rock bottom prices because those flooring contractors are in High demand and have the positive reputation to prove it.  Our hardwood flooring contractors are C15 licensed (hardwood floor specialist), bonded and insured for your protection.  We can go a step further and say that our company has a "No deposit policy".  You don't pay until the work is completed.  

Sandless refinishing vs. Sand and finish hardwood floors

There are companies out there that are selling a "Sandless" refinishing process.  What is a hardwood "Sandless" refinishing process?  It's basically a shortcut process that most consider a Sham!  It's merely a maintenance program or technically the very last step in a full sand and finish process.  Without getting into too much detail, you can NEVER restore a hardwood floor with a sandless hardwood refinishing system.  This service, in essence, is masquerading the sale of one service for another.  Sandless hardwood refinishing is typically performed by a person who does NOT possess a C15 (Hardwood floor specialist) contractors license.  More on that later.  This sandless refinishing maintenance program, which we refer to as "ReCoating", will not correct hardwood floor issues like deep scratches or gouges.  If you have other issues with your hardwood floor like sun fading or discoloration, this sandless option will not correct the problem.  Why not?  Because you will just be top coating the existing floor.  Another way to look at it is, if you want to paint a car with a minor dent and some dings and decide to pass on the body work, you will be left with a shiny car that has a minor dent and dings.  Those mechanical imperfections cannot be corrected with a re-coat. 

The "Only" way to erase deep scratches, gouges and discoloration in hardwood floors would be to mechanically correct them with a sanding and finish process.  When you sand the floor, you are creating a new canvas.  When you have a fresh new starting point, the floors will look like new again, every time.  You can't get the same results with a re-coat.  If you have seen a re-coated floor next to a sand and finished floor, there is absolutely no comparison.  The sanded floors are without doubt superior in appearance and durability.  When the floors are sanded, they are top coated 3 times with commercial grade materials that can only be purchased by licensed contractors.    

Bamboo hardwood floor refinishingRefinishing Bamboo floors min

National floors is pleased to inform you that we do refinish bamboo flooring.  Most people think that bamboo is a hardwood, but in fact, bamboo comes from the grass family.  Bamboo flooring is probably one of the best bangs for the buck.  It looks great and is on the affordable side.  The hardness of bamboo is impressive and resist damage better than a lot of the hardwood flooring sold.  National floors is pleased to inform you that we do refinish bamboo flooring and also offer the option of color change through a staining process.  Yes, Bamboo accepts stain, so you can have the color of bamboo floor that you have always wanted.       

Hiring a contractor that is not licensed 

Here's the negative with a sandless refinishing option for your hardwood floors:  If a "Sandless" company comes into your home and does not hold a contractors license, they would be classified as a "Handyman".  In other words, a contractor without a license is not a contractor.  In short, these people lack the professional skill set you are paying for and even worst, they are breaking the law!  

California state law says"Therefore, persons engaged in the business of home improvement must be licensed in the appropriate trade before advertising and/or submitting bids for construction and construction-related services. The license requirement is for jobs that total $500 or more in labor and materials (BPC ยง 7028)"   

Take a moment and do a FREE background check with the California State License BoardHere, in a matter of moments, you can quickly see if the person/company you are thinking about hiring is legitimate.  Just type in the license in the box to see if the person or company passes the test.  You will also quickly come to see if person/company is bonded, carries liability insurance and workers compensation insurance.  The law is here to protect you and your home from people posing as licensed contractors.  If you don't take this serious, you will likely be the person to fall victim from illegal behavior. 

What happens if an Unlicensed contractor messes up my hardwood floors?

  • You cannot contest their license.
  • You cannot collect from their liability company because a company "Must" posses a contractors license in order to be insured
  • You cannot put a lien against their bond because they don't have one.  Only licensed contractors carry a bond
  • You can take them to court if you can find them.  Most of these guys change their phone number and go under the radar once exposed
  • That deposit you gave them is gone.
