Experienced, honest, and ready to handle any need for subfloor repair in Renton

Underneath the flooring that you can actually see in your home or building is the subfloor. When getting new flooring (hardwood flooring, carpet, etc.), it's crucial for this support layer to be flat and sturdy. If not, the visible floor could look odd, it could wear down more quickly, and it could even become a safety risk for you and your family. Before putting in a new floor, it's wise to make sure the subfloor is in top shape. Most flooring manufacturers have guidelines about how to level the subfloor needs to be BEFORE attempting to lay their quality flooring. How do you know if your subfloor is strong enough and flat enough to proceed with the installation? Your current flooring must be taken out and an expert needs to check the subfloor for you to be sure. If you're ever in doubt or suspect any subfloor issues, don't hesitate to contact us at Professional Flooring Installations.

PFI is a flooring contractor, but we repair subflooring as well, when other don't.

You may be planning a new flooring replacement or installation, then you hear that your subfloor isn't even or requires some fixing. We do a lot of flooring installation, but we also handle subfloor repairs. Not every company out there offers this service. After pulling up your current floor, a contractor might halt everything, saying that they can't proceed until the subfloor is strengthened or leveled out. That's where we, Professional Flooring Installations, jump in as your go-to service for subfloor repair in Renton. Here's a glimpse of typical issues we regularly tackle:

Concrete's Ups and Downs: Got an old concrete floor? Before laying new hard flooring, some prep might be needed. If carpet covered it before, the concrete's bumps might've been ignored since carpet masks most flaws. We can sometimes level just specific parts; other times, the whole floor needs leveling. Got questions? Your flooring specialist can provide answers and possibly give an early estimate.


Those Noisy Floors: Homes, whether old or new, sometimes have floors that creak as you walk. Often, this is because the subfloor isn't tightly attached to the frame below. Knowing this early helps us secure those spots. While we often fix this, there are cases where the noise has unfixable causes. We'll keep you informed.


Wobbly Plywood: Here in the Pacific Northwest, many homes are built during rainy spells. This can make the subfloor expand and twist. Before your floor upgrade, we'll tackle this issue. This might involve sanding bulging areas or using a special mix to fill in the dips. Once your old floor's up, our team will assess what needs doing.


Dipping Floors: Floors that dip or feel mushy often have water damage or weren't set up right. For water issues, we typically swap out the ruined part with fresh plywood. If the subfloor type is the issue, we'll let you know the cost to switch it.

Slanted or Tilted Floors: Common in basements or homes on "Post and Beam" bases. The fix varies with the flooring type you're getting. In basements, we typically level the floors. For wooden subfloors, we might layer on plywood to balance things out or fill depressions.


You're definitely gonna want to set your subfloor straight and strong before laying down brand-new hardwood flooring, laminate, luxury vinyl flooring, carpet, etc. is crucial. By getting professional subfloor repair or having subfloor leveling performed, you are setting yourself up for success and greater flooring longevity. Keep in mind, though, that subfloor fixes can range in cost and in just how involved they may be. Remember though, that seasoned professionals like the ones we send out have been at it for years and will always offer you an honest assessment and estimate---and we're pretty accurate with both!
