Schmidt Painting · Serving Nassau & Suffolk County
Drywall Installation & Repair on Long Island
Paint can't hide bad walls. We repair holes, cracks, water damage and failing plaster — and skim coat rough walls smooth — so the surface under the paint is as good as the finish on top. Small patch or full room, it's finished flush, sanded and paint-ready.
What's Included
Four decades of experience, the same supervised crew, on every kind of Long Island home.
Hole Patching
Doorknob holes, anchor damage and dents patched flush and sanded smooth.
Water Damage Repair
Damaged board replaced, taped and sealed with stain-blocking primer so marks don't bleed through.
Crack Repair
Settlement and seam cracks fixed properly so they don't come right back.
Skim Coating
Rough, textured or damaged walls skim coated to a smooth, even surface.
Plaster Repair
Older Long Island homes with plaster walls repaired with the right materials.
Full Rooms & Ceilings
New drywall hung, taped and finished for renovations, basements and popcorn ceiling work.
Common Questions
Do you paint the wall after fixing the drywall?
Yes — repair and paint in one job, blended so you can't find the patch afterward.
Can you fix a water-stained ceiling?
Yes. Once the leak itself is fixed, we replace or repair the damaged board, then prime with a stain-blocking sealer so the stain never bleeds through the new paint.
Is a small repair too small to call about?
No — small patch jobs are welcome, and we'll quote them honestly.
