House Painters in Washington
Interior and exterior painting — connected with a licensed contractor who understands that preparation, not product, determines how long the finish lasts.
Find a ProWhat painting work covers
Painting covers interior and exterior work, surface preparation, priming and finish coats, plus repair of failed substrate before painting. In Washington, exterior painting requires a genuine dry window and a substrate that is dry below the surface, because trapped moisture pushes coatings off from behind.
Painting produces a disproportionate number of disappointed homeowners, and almost always for the same reason: the preparation was inadequate and the failure appeared two years later.
The visible part of painting is applying paint. The part that determines how long it lasts is everything before that — washing, scraping, sanding, repairing rot, filling, caulking and priming. A quote that allocates most of its labour to preparation is describing a job that will last.
Timing matters more here than in most states. Exterior paint needs a dry substrate and dry conditions during application and curing, which compresses the Washington season considerably. Critically, the surface must be dry below the surface — timber that has been wet holds moisture that then pushes the coating off from behind.
East of the Cascades the problem inverts. Intense sustained sun degrades finishes far faster than anything moisture does in Seattle, so repainting intervals are shorter and colour choice genuinely affects longevity on sun-exposed elevations.

Interior versus exterior scheduling
These are effectively different trades with different constraints, and sequencing them well saves money.
| Aspect | Exterior | Interior |
|---|---|---|
| Season | Compressed into drier months | Any time; winter is quieter and easier to book |
| Main constraint | Substrate and weather must both be dry | Ventilation, particularly in a sealed winter house |
| Preparation | Washing, scraping, rot repair, priming | Filling, sanding, addressing stains at source |
| Failure mode | Peeling from trapped moisture or poor prep | Recurring stains where the cause was not fixed |
| Booking | Competes for the dry window with all exterior trades | Contractors are less stretched in winter |
If you are planning both, do interior work in winter and exterior in the dry season. That uses two different parts of the year rather than competing for the same booked-out months.
What drives the cost
Two quotes with the same number of coats can describe entirely different jobs.
Area and access
Storeys, height and awkward access all add staging and labour.
Preparation required
The largest variable. A sound surface needs washing; a failing one needs extensive scraping, sanding and priming.
Substrate repair
Rot found during preparation must be repaired before painting. Common in Western Washington.
Surface condition and material
Previously failing paint, bare timber and different substrates all change preparation and coats.
Lead paint requirements
Pre-1978 homes may require specific handling when disturbing existing paint.
Number of coats and product
Genuine differences, though smaller than preparation in most quotes.
Ask each contractor to state preparation specifically — how much scraping and sanding, whether washing is included, what is being primed and why, and what happens if rot is found.

The quality difference is invisible on completion day and obvious three winters later.
What a good contractor will do
- Hold an active L&I contractor registration, bond and insurance
- Specify preparation in detail rather than as a single line
- Confirm the substrate is dry before starting, not merely the weather
- Treat mildew and algae on shaded elevations before painting
- Raise lead paint requirements on pre-1978 homes
Warning signs
- Quoting by area with no preparation detail
- Painting over mildew or failing paint
- Working on a damp substrate to keep the schedule
- Painting over recurring stains without finding the cause
- No mention of lead on an obviously older home
Paint peeling in sheets rather than flaking usually means water is reaching the substrate from behind. Repainting without finding that source repeats the failure, and a good contractor will say so rather than quote the repaint.

Painting FAQs
During the drier months, and it needs a genuine dry window rather than a dry day. The substrate must be dry below the surface, not just surface-dry after recent rain, because painting over trapped moisture pushes the coating off from behind.
That pattern usually indicates water reaching the substrate from behind rather than a coating failure — a flashing problem, a leak, or trapped moisture. Repainting without finding the source repeats the failure regardless of how good the new paint is.
In Western Washington, essential rather than optional. North-facing elevations and anything shaded by trees grow mildew and algae, and painting over it means it continues growing beneath the new coating. It is the preparation step most often abbreviated.
Less often west of the Cascades than east. Intense sustained sun in Spokane, Yakima and the Tri-Cities degrades finishes considerably faster than moisture does in Seattle, particularly on south and west elevations, so eastern intervals are shorter.
If the house predates the prohibition, it is a genuine consideration. Disturbing lead paint through sanding or scraping creates a real hazard, and there are specific requirements for renovation work on older homes. Raise it explicitly with any contractor.
For exteriors, generally yes. For interiors it is a good time — contractors are less stretched, and it does not compete for the dry window that all exterior trades need. Ventilation matters in a sealed-up winter house.
