Subfloor repair & leveling on Staten Island
A new floor on Staten Island is only as good as what is under it, so we inspect, repair and level the subfloor before boards go down. Our flooring company is family owned and licensed and insured, and your flooring contractor plans the job with you in person. Call (718) 690-3435.
Subfloor repair & preparation for Staten Island single-family houses
Staten Island subfloor work is mostly in houses: split-levels, colonials, newer builds and homes near the shore. The fix is usually planned alongside a new floor. Subfloor work jobs come up across St. George, Tottenville, Great Kills, New Dorp and Midland Beach. Our Staten Island flooring page covers what else we do on Staten Island besides subfloor work.
Common problems in Staten Island houses
Newer houses often have OSB or plywood that can swell where water from a dishwasher, toilet or window leak soaked in. Older houses may have plank subfloors with gaps and loose boards. Additions built at different times often leave a height change at the doorway. In split-levels, the lower level usually sits on a slab that can dip toward a wall or drain.
Shore houses and moisture
In homes near the shore, moisture from below can soften wood subfloors over crawl spaces and raise readings in slabs. We take readings before recommending any floor, and where moisture stays high we suggest a floor that tolerates it, such as waterproof vinyl plank or tile, rather than hardwood. Soft or swollen panels are cut out and replaced with sound material.
Work we do
Soft spots
Swollen or rotted panels are cut out and replaced.
Squeaks and bounce
Loose areas are fastened, and weak spans reported so they can be reinforced.
Height changes
Additions and patches are leveled so floors meet without a bump.
Slab leveling
Low spots in basements are filled before a new floor goes down.
Kitchens and baths
Kitchen and bathroom remodels on Staten Island often uncover subfloor damage from years of small leaks. We replace the damaged area, check the base under cabinets and the toilet flange height, and prepare the floor for tile, vinyl or wood as planned. See our main subfloor repair page and tile installation on Staten Island.
Showing you what we found
Subfloor repairs are hidden once the new floor goes in, so we show you the damaged areas before covering them and explain what was replaced or leveled. Repairs are listed as their own line on the estimate. If the subfloor turns out to be sound, we tell you and go straight to the new floor.
Split-level and raised-ranch quirks
Split-levels and raised ranches are common on Staten Island, and each level brings its own subfloor. The upper floor usually has plywood over joists, the entry level may have a short stair landing framed separately, and the lower level is typically a slab with a family room or garage conversion. Where these levels meet, height and stiffness can change within a few feet. We check each area separately, then plan repairs so the new floor runs smoothly across landings and doorways.

What affects the cost
How much of the subfloor needs repair and whether it needs leveling compound or new sheathing account for most of the difference. Access, stairs and hidden repairs under the old floor can also change the plan. If you want a first look, get an instant preliminary estimate.
Frequently asked questions
Why is my floor soft near the dishwasher?
Water has likely swollen the subfloor there. We cut out the damaged area and replace it.
Can you level an addition to meet the old floor?
Yes. We level the base so the floors meet without a bump at the doorway.
Does a shore house need a moisture check before new floors?
Yes. Readings decide whether hardwood, vinyl plank or tile is the right choice.
