Preparation: the part you don't see

Most of a good paint job happens before the first coat. This page shows what we do to each surface, and why.

Why prep matters

Paint needs a clean, sound, slightly keyed surface to grip. Prep gives it that, smooths out dents and cracks so they don't show through, and gives crisp edges where colors meet. It is also most of the time on a job.

Yes means always part of the job. If needed means it depends on the condition, confirmed at the estimate visit.

Condition guide

What you might notice, and what it usually means for prep. Every surface is checked at the estimate visit.

Peeling or flaking

What you see: Paint lifting in strips or flakes, often on trim and sunny walls.

What it usually means: Loose paint is scraped off, edges are sanded smooth and bare spots are primed.

Chalking

What you see: A powdery film that rubs off on your hand.

What it usually means: The surface is washed as prep so new paint can grip.

Cracked caulk

What you see: Gaps opening along trim, corners and joints.

What it usually means: Old caulk is cut back where needed and the joint recaulked.

Water stains

What you see: Brown or yellow rings, often on ceilings.

What it usually means: Spot priming with a stain-blocking primer, once the cause is fixed.

Mildew-looking spots

What you see: Dark speckles in damp or shaded areas.

What it usually means: Cleaning as prep before painting. We point out anything that looks like an ongoing moisture problem.

Nail pops

What you see: Small bumps or circles on drywall.

What it usually means: Reset, filled, sanded and spot primed.

Protection

Everything near the work is covered or masked before any prep starts, inside and out.

Inside

  • Floors and stairs covered
  • Furniture moved and covered
  • Light fixtures, switch plates and hardware masked or removed

Outside

  • Plants and beds covered
  • Paths and patios protected
  • Outdoor fixtures masked

Older homes and older paint

Built before 1978, or not sure? Tell us. Older paint may contain lead, and we will talk it through at the estimate visit.

Demo note: On a real site, the business adds any lead-safe credentials here only if they genuinely hold them.

Tell us in your enquiry

  • Which rooms or sides of the house
  • Anything you have noticed: peeling, cracks, stains, chalking
