EXTERIOR PAINTING COST GUIDE
DC, MD & VA (2026)

DMV weather is tough on exterior paint. The region cycles through humid summers, freezing winters, and everything in between. That combination of moisture, temperature swings, and UV exposure breaks down paint faster than drier climates. Knowing what to budget for a proper exterior paint job helps you plan and avoid being underbid by crews who skip the prep work that actually makes a paint job last.

EXTERIOR PAINTING COSTS BY HOME SIZE

The biggest driver of cost is the total paintable square footage of your home's exterior, which includes siding, trim, shutters, doors, soffits, and fascia. Here are typical ranges for the DMV market in 2026:

These ranges assume professional prep work, primer where needed, and two finish coats of quality exterior paint. Jobs with significant wood rot repair, many architectural details, or extensive masonry work may run higher. Always ask for an itemized proposal that separates labor, materials, and any repair work.

WHAT'S INCLUDED IN A PROPER EXTERIOR JOB

A professional exterior paint job is not just rolling paint on siding. Prep work accounts for roughly 40% of the total labor on any exterior project, and it is the part that determines how long the paint job actually lasts. Here is what should be included in a complete exterior painting service:

• Power washing the entire exterior to remove dirt, mold, mildew, and chalk
• Scraping any existing peeling or flaking paint down to a solid surface
• Caulking all gaps around windows, doors, trim, and siding joints
• Spot priming bare wood, repaired areas, and stain-prone surfaces
• Two full finish coats of exterior paint
• Masking and protecting all windows, doors, and landscaping
• Final cleanup and debris removal

If a contractor quotes you an exterior job and mentions nothing about power washing or caulking, that is worth asking about directly. Painting over a dirty or un-caulked surface is one of the main reasons exterior paint peels within a year or two.

PAINT QUALITY MATTERS

There is a real and measurable difference between professional-grade exterior paint and lower-end products. Sherwin-Williams Duration and Emerald Exterior are two of the most commonly recommended lines for the DMV climate. They have higher pigment density, better mildew resistance, and improved flexibility to handle the temperature swings the region sees. A gallon of Duration runs around $75 to $85 versus $25 to $35 for a builder-grade exterior paint.

That difference adds roughly $200 to $400 to the material cost of a typical exterior job. In exchange, you typically get a paint film that lasts 2 to 3 years longer, resists the mold and algae growth that the DMV's humidity promotes, and holds its color better under the summer UV load. Over a 10-year window, the premium paint almost always costs less per year than repainting sooner with a cheaper product.

HOW OFTEN TO REPAINT IN THE DMV

With a quality paint product and proper prep, exterior paint on a DMV home should last 7 to 10 years before it needs a full repaint. Homes on the north side or under heavy tree cover tend to see more moisture retention and algae growth, which can shorten the cycle. Homes with older wood siding or a lot of south-facing exposure to direct sun may need attention sooner.

Signs that it is time to repaint before the 10-year mark include visible peeling or bubbling (moisture is getting under the film), chalking (a powdery residue that wipes off on your hand), significant fading that makes the home look dull or uneven, or caulk that is cracking and pulling away from trim. Any of these conditions means moisture can now get into the wood substrate, which accelerates damage and raises repair costs.

BEST TIME TO PAINT EXTERIOR IN THE DMV

Spring and fall are the ideal windows for exterior painting in DC, Maryland, and Virginia. The target conditions are temperatures between 50 and 85 degrees Fahrenheit and relative humidity below 70%. Paint adheres and cures properly in those conditions. The DMV spring window typically runs from mid-April through mid-June and the fall window from mid-September through early November.

July and August are the hardest months for exterior painting in the DMV. High heat and humidity slow dry times, increase the chance of lap marks, and can cause paint to blister if applied to hot siding in direct sun. Painting below 40 degrees is also a problem because most latex exterior paints do not cure properly in the cold and the film can crack before it fully hardens. If you are planning an exterior project, booking for spring or fall gives you the best outcome.
