Interior Remodeling — Centereach, NY

Interior &
exterior painting

Interior and exterior house painting in Centereach and across Long Island, with real prep and repairs done before the first coat.

Interior and exterior painting covers walls, ceilings, trim, doors, siding and railings, but the finish only lasts as long as the surface under it. JDG paints Long Island homes as a general contractor: we patch, caulk, prime and replace rotted trim before color goes on, so the paint shows the room, not the flaws.

What is included

  • Floor and furniture protection
  • Patching, sanding and caulking
  • Priming repairs and bare spots
  • Walls, ceilings, trim and doors
  • Exterior scraping and cleaning
  • Rotted trim replaced
  • Hand-cut lines at trim

Why it lasts

Peeling starts where water gets behind the finish. Outside, we clean, scrape loose paint, caulk joints and prime bare wood before finish coats, so weather works on sound paint instead of an open seam.

Inside, stains are sealed before they can bleed through and damaged trim is replaced, not painted over. Homeowners in Selden, St. James and Smithtown get a written scope listing every surface and prep step.

Questions homeowners ask

Do you repair trim and drywall before painting?

Yes. Patching, caulking, priming and replacing damaged trim are part of our prep, because paint shows every flaw underneath it.

Do you paint both inside and outside?

Yes, interior rooms, ceilings, trim and doors, plus exterior siding, trim, doors and railings.

When is the best time to paint the exterior on Long Island?

Mild, dry weather. Spring through early fall usually works, as long as surfaces are dry and nights are not too cold for the coating to cure. We schedule around the forecast.
