Basement floors, leveled and ready for flooring

Sloped or cracked basement slabs, leveled or repoured for new flooring.

Basement Floors

What we do

Old basements in the Seattle area rarely have a flat floor. We level sloped slabs, fill low spots and patch old trenches, or tear the floor out and repour it, so the new flooring goes down flat.

Our customers come to us before hardwood, tile, heated floors or an epoxy finish goes in. One had a 1.5" slope over 18 feet; we prepped the floor and leveled it to the footing within a day.

Out with the old floor

For a 1918 craftsman, the floor was "partially with blocks and partially poured concrete." The crew removed most of it, put down a vapor barrier, then repoured and leveled the floor and finished it in epoxy.

Clean cuts, clean site

When a basement has old holes or a trench from an oil tank, we cut clean lines around them, fill underneath and patch with new concrete. Customers mention that we clean up the dust before we leave.

“Mel’s team did a wonderful job. We have a 1918 craftsman, and our basement floor was quite unlevel, partially with blocks and partially poured concrete. Mel and his crew removed the majority of the concrete, put down a vapor barrier, and then repoured and leveled the floor. Finally, he placed an epoxy floor down. It looks great, and the price was reasonable!”

“If you're looking for a contractor to help with your concrete needs look no further. The professionalism and value that Melgrik and Melbigaldana Concrete brings ot the table is second to none. I had a 1.5" slope over 18' and they cam in, prepped the floor and leveled everything to my footing within a day. They came back 2 days later to fill a low spot that developed and even patched a nail hole that I had forgotton to mention. These are true professionals and are a pleasure doing business with. I will be recommending them to any of my friends and family that need work done. Highly recommend working with Melbigaldana!”

“Melgrik did great and quick work on our basement concrete. We had a few holes and an open trench that pre-existed our purchase of the house, from what we assume was an old oil tank and line. He cut clean lines around the existing holes, filled in areas that had become exposed underneath our existing concrete and then added new concrete to the patches. He also did a great job cleaning up after the project and cleared up all of the dust from the installation. He was easy to work with and did high quality work!”

“I've had enough negative experience with contractors recently that I am almost more inclined to DIY. However, when we were planning to take on remodeling our home and realized we needed a 1000sf of concrete re-poured to allow for hardwood installation where we previously had carpet I knew I needed professional help. Melbigaldana quickly estimated the project and went the extra mile to get it done, working late and making sure everything was perfect. This was a big job and I sincerely appreciated his work ethic and quality all for a fair price.”
