Not every floor problem is a new floor. A dip that has opened up near a hallway, a board that moves underfoot, a squeak that started one winter and never left, a soft spot by the dishwasher: these are repairs, and repairing them well costs a fraction of replacing a floor that is mostly fine.
AG Construction repairs floors across Maryland and Northern Virginia as part of the same MHIC-licensed flooring work we do every day. We find what is actually wrong, tell you plainly whether it is a flooring fix or something bigger, and give you a free written estimate either way.
What We Repair
Sagging & Uneven Floors
Dips, slopes and bounce usually trace to the structure under the boards. We open the floor from above, correct the subfloor and framing support where the fix belongs to the floor system, and relay the finish floor so the repair disappears.
Subfloor Repair & Replacement
Water, age and undersized panels ruin subfloors long before the finish floor shows it. We cut out and replace failed sections, re-fasten what is loose, and level so the new surface goes down flat and stays quiet.
Squeaky Floor Repair
Squeaks are movement: board on nail, panel on joist. We locate each one and fasten it properly instead of covering it up, which is why the fix holds.
Board Replacement & Spot Repair
Pet stains, deep gouges, burns and water-marked boards can be replaced individually and blended into the surrounding floor with sanding and finish, so you are not refinishing three rooms to fix one doorway.
Water & Moisture Damage
Cupped, crowned or buckled wood after a leak needs drying time, then honest triage: some floors flatten and refinish, some need boards replaced, some need the subfloor addressed first. We tell you which one you have.
Parquet & Specialty Repairs
Parquet, herringbone and older solid floors can almost always be repaired rather than replaced. Matching species, cut and finish is the craft; it is also the difference between a patch and a repair.
Sagging Floors, Joists and the Structure Underneath
When a search says "best contractors for sagging floor joist repair", what the house usually has is one of three things: subfloor panels that have weakened or pulled loose, support directly under the floor system that needs sistering or blocking, or true structural settlement. The first two are flooring-side repairs and exactly the work we do: we open the floor from above, correct the subfloor and the framing support that belongs to the floor system, and relay the finish floor so you cannot find the spot afterward.
The third one, foundation settlement or work that needs an engineered fix, is not a flooring repair, and the most valuable thing we do on those calls is say so plainly at the free assessment before you spend flooring money on a structural problem. You bring in the right specialist, and when the structure is corrected we put the floor back over it properly.
Older housing stock across Montgomery County and the rest of the DMV makes sagging and bouncy floors one of our most common calls. If a dip, slope or bounce has appeared in your floor, the assessment is free and the estimate is written either way.
How A Repair Visit Works
First, the assessment. We look at the floor, under it where access allows, and at what caused the problem, because repairing the symptom without the cause is how you pay for the same repair twice. You get a free written estimate that says what we found and what we would do about it.
Second, honesty about scope. Most sagging and movement is corrected from the flooring side: subfloor, fastening and support as part of the floor system. When the cause is foundation settlement or needs engineered structural work, we say exactly that and you bring in the right specialist before spending money on flooring.
Third, the repair itself, finished to match. Owner Aaron Goodman has over 10 years of hands-on flooring experience across the DMV, and the standard for a repair is simple: when the furniture goes back, you should have to point the spot out.
Repair Or Refinish?
If the damage is spread across the surface of the whole room, thin finish, gray boards, wall-to-wall scratches, you want refinishing, and repairs get folded into that job. If the floor is structurally tired everywhere, that is restoration. If the problem lives in one place, a doorway, one run of boards, one bouncy corner, a repair is usually the right-sized answer, and we will tell you if it is not.
