A basement floor in Warrenville that stays flat and holds up from below, because we test the slab before we lay a single plank.
We install luxury vinyl plank and tile, laminate, engineered hardwood and tile, along with stair treads, risers and nosing. On a concrete slab the first step is a moisture test, since a floating floor over a damp slab fails from the bottom up and nothing on top can save it. Above grade, we check the subfloor against the product's flatness spec and level, patch or sand it until it passes. Base, shoe and transitions come with the install, and we move the furniture out and back.
We work in Warrenville every week, reaching it on I-88 and Route 59, with Butterfield Road and Winfield Road taking us through town. It sits in DuPage County along the West Branch of the DuPage River, near Fermilab. If your house has a basement with a bare or painted slab, that concrete passes moisture up from the ground even when you never see water on it. We test it before we recommend a floor, then pick the underlayment and the product around the reading instead of hoping for the best.

We test the slab before any product is chosen, because the reading decides what can go down and what cannot.
Where the slab calls for it, a vapor barrier or an underlayment with one built in goes down first.
Low spots in the concrete get patch or self-leveler, and high ridges get ground down until the floor is flat.
Luxury vinyl plank and tile hold up below grade, and we tell you plainly when laminate or wood is the wrong pick for the room.
Treads, risers and nosing can be covered to match the new floor, so the stairs and the room look like one job.
Base, shoe and a transition at the stairs or the mechanical room door are part of the job.
At the free estimate we measure, look at the subfloor or slab, and take a moisture reading wherever concrete is involved. The written scope lays out the test result, the prep and the product, so the reason for every line is on paper. Anything that turns up once the old floor is gone gets priced in writing, and nothing proceeds until you sign off on it. We book the install around the days we gave you, and we walk the room with you when the trim is on.
