Pros & Cons of Basement Cork Flooring

Pros
Cons
  • Warm flooring compared with tile, wood etc
  • Comfort underfoot
  • Good insulation qualities
  • Reduced noise and vibrations
  • Sustainable
  • Healthy – Natural cork has no VOCs or toxic chemicals.
  • Hypoallergenic
  • No good in a basement that could be flooded
  • Expands and contracts with changes in temp and humidity changes
  • Fades in sunlight (this con is no issue in a basement)

With no natural light, basements need all the help they can get to feel warm and inviting. The two types of flooring that offer a warmer feel are carpet and cork. Obviously, basement carpet is the most inviting but cork runs it a close second. Warmer and more forgiving underfoot, cork is also quiet and very stable, qualities that you will appreciate in a confined, sometimes echoey, basement space.

With no windows how do you plan to ventilate your basement? Whatever the answer you’ll appreciate having a healthy and hypoallergenic cork floor that’s easy to keep clean.

It can be hard to keep a basement warm and flooring insulation is often a good idea especially in cold climates. Cork already has a high insulation R-value. Add some cork underlayment below your cork floating floor and you’ll really keep the heat locked in.

Even one of cork flooring’s disadvantages turns out to be a plus when used in a basement. With no natural sunlight you don’t need to worry about fading!

The one big concern you have with cork flooring (much like hardwood) is moisture. You will need to look closely at the warranties of each and every cork flooring product that you’re considering to see what the manufacturers have to say about installation below grade.

Let’s take a look at your cork flooring options and how they work, or don’t work, in different basement settings.

Types of Cork Flooring

You have two options for cork floors, either glue down cork tiles or a click & lock plank (or tile) system, much like laminate, that you install as a floating floor.

Glue down cork tiles are attached directly to the surface of the floor and the adhesives used do not mix well with moisture at all. We will talk about installation instructions and warranties for major cork flooring brands later on, but for now, know that you shouldn’t glue cork tiles directly onto a below grade concrete floor and even gluing cork onto a plywood sub-floor will only work in certain conditions when used below grade.

You have much more room to maneuver with an engineered cork plank or tile floating floor. As you will learn, manufacturers still have guidelines about moisture levels and you will need to get familiar with moisture barriers and suitable basement underlayment, but generally speaking you have plenty of great options to choose from.

Basement Basics – There are three types of basement situations found in any home, which one best describes your basement?

  • Unfinished Basement – This is stage 1; you have a bare basement with a concrete slab and not much else. It may be damp or it may not be…yet.
  • Semi-Finished Basement – At stage 2 you’ve taken some steps to make your basement into a practical living space. Your concrete is sealed and you have humidity under control.
  • Finished Basement – This is the ideal and final 3rd stage. Your basement has been fully renovated and interior (or exterior) drainage systems have been installed making moisture a problem of the past.

Let’s narrow things down by excluding one of these options straight away…an unfinished basement. If you haven’t taken any steps to control moisture levels in your basement then the only flooring you should consider is a completely waterproof option. There are waterproof basement flooring options and you can read about them here.

A semi-finished basement is a scenario that many homeowners know well. You’ve treated the walls, sealed the concrete basement floor and taken care of ventilation, maybe installed a dehumidifier. In this situation you have a number of suitable cork flooring options for your basement, but you will need to read the installation instructions for each cork flooring product before you begin and then undertake proper moisture testing. Most cork manufacturers these days allow for their cork flooring to be installed in a basement, but many have very specific guidelines around acceptable levels of hydrostatic pressure.

Engineered cork planks installed as a floating floor, with a 6-mil moisture/vapor barrier beneath, is standard for basement concrete. If you have your heart set on glue down tiles or want to give your floating floor added protection why not consider a moisture resistant underlayment or subfloor?

Home Depot and other big box stores offer a number of underlayment options that can be used in conjunction with your moisture barrier and will give peace of mind. A good simple option sold at Home Depot is DMX 1-Step underlayment specifically designed for basements. An alternative option, and good for glue down cork as well, is an insulated sub-floor panel system like the ones produced by Amdry, also sold at Home Depot. They’re more expensive but they also offer insulation along with moisture protection.

Pro Tip – If you’re planning to hire a professional for cork flooring installation then they should be offering a moisture testing service before the project gets going. If you are planning to DIY you will have to get these tests done yourself. If you have a problem after installation your warranty may be voided if you can’t produce evidence of moisture tests.

Finally, if you have gone to the trouble of completely finishing your basement, or are fortunate enough to have bought a property where the work has already been done, then you are free to choose any cork basement flooring that you want. We would still recommend installing any glue down cork tiles onto a subfloor.

How Much Will It Cost to Install Cork Flooring in a Basement?

As you can see from the cork flooring prices above, buying your cork floors could cost you anywhere between $1.99 per sq/ft to $12.40 per sq/ft…that’s quite a range.

In a basement, over a concrete slab you will also need to install a moisture barrier and underlayment which will add a further $0.50 to $1.25 per square foot

Finally you can then expect to pay a professional installer around $2 per sq/ft for installation.

So installing cork flooring for a basement is likely to cost you between $4.50 and $15.65 per sq/ft with the average likely to be somewhere between $7 and $8 per sq/ft.

Home Flooring Pros Conclusion

We like cork flooring as a basement flooring option. With its good insulation, good looks and healthy air attributes cork flooring really suits an enclosed basement space. Cork is not a cheap option, so we would want to be absolutely sure that there were no flooding risks or moisture problems in your basement before installation.
