Exterior painting in Cohasset typically costs $6,000 to $14,000 for a 2,500 sq ft home with proper prep and two coats. Nationally, the average cost to paint a house exterior is $3,177, with most projects falling between $1,819 and $4,551.[1] The South Shore premium reflects Massachusetts labor rates, multi-story scaffolding needs, and the coastal prep work that Cohasset homes require to hold a paint job for more than a few seasons.
US ProPaint & Renovation, a licensed Massachusetts contractor (License 186517) based in Hingham and serving Cohasset, Scituate, and Norwell for more than 23 years, paints South Shore homes every season. The figures in this guide reflect both verified national data and the realities of coastal New England prep and materials.
The national average exterior painting cost is $3,177, or $1.50 to $4 per sq ft, covering labor, primer, and paint.[1] In Cohasset and the South Shore, that per-sq-ft range climbs to $2.40 to $5.60 for a complete project with two finish coats, full prep, and coastal-grade primer — reflecting higher regional labor and the premium materials required for marine air exposure.
Here is how exterior painting cost breaks down by project size for Cohasset homes:
Home Size | Stories | Scope | Estimated Cost (Cohasset / South Shore) |
1,000–1,500 sq ft | 1-story | Full repaint, 2 coats | $3,500 – $6,000 |
1,500–2,000 sq ft | 1 to 2-story | Full repaint, 2 coats | $5,500 – $9,000 |
2,000–2,500 sq ft | 2-story | Full repaint, 2 coats, spot repairs | $7,000 – $12,000 |
2,500–3,500 sq ft | 2-story, detailed trim | Full repaint, 2 coats, priming, carpentry prep | $10,000 – $18,000+ |
Most Cohasset projects land in the $7,000 to $12,000 band — a two-story colonial with cedar clapboard or fiber cement siding, detailed window trim, and a full prep sequence including power washing, scraping, caulking, and spot priming.
A local worked example: A 2,400 sq ft cedar clapboard colonial in Cohasset — two stories, full wrap, power wash, spot scraping and caulking, one oil-based prime coat on bare wood, and two finish coats of premium acrylic latex — typically runs $9,000 to $12,500 with a crew of three to four painters over four to seven days.
For a complete exterior paint job in Cohasset, plan on $2.40 to $5.60 per sq ft all-in, including labor, materials, and prep.[1][2] That per-sq-ft figure covers far more than paint — here is what a complete professional project includes:
Labor accounts for roughly $1 to $2 per sq ft of the total project cost, or $25 to $100 per hour per painter.[1] On a $10,000 project, expect materials — paint, primer, caulk, tape, and supplies — to represent 25% to 35% of the total, with labor taking the remainder.
Cohasset coastal homes need premium acrylic paint and salt-resistant primers to withstand harsh winter winds and summer humidity. Skipping the primer or using a lower-grade paint to reduce upfront cost is the most common reason a Cohasset exterior paint job fails before the five-year mark.

Most exterior paint jobs last five to 10 years, depending on siding material, paint quality, and climate.[3] In Cohasset’s coastal environment — salt air, freeze-thaw cycles, summer humidity, and UV exposure from direct ocean-facing light — wood-sided homes near the harbor typically need repainting every five to seven years. Homes with fiber cement or vinyl siding and a properly applied premium coat can stretch closer to 10.
Here is how repaint frequency varies by siding type in the South Shore climate:
Siding Type | Typical Repaint Cycle (Coastal New England) |
Cedar or pine clapboard | 5 to 7 years |
Fiber cement (HardiePlank) | 8 to 12 years |
Vinyl siding (if painted) | 10 to 15 years |
Stucco | 5 to 7 years |
Brick | 15 to 20 years |
Plan exterior painting in Cohasset between May and October when temperatures and humidity allow proper adhesion and curing of finishes.[3] Most exterior paints require surface and air temperatures above 50°F during application and for at least four hours after — a threshold that limits the working season in Massachusetts to spring through early fall. Painting in cold or wet conditions is the fastest path to premature peeling.
Signs your Cohasset home is due for exterior painting:
The national average cost to paint a house exterior is $3,177, with most projects ranging from $1,819 to $4,551. In Cohasset and the South Shore, exterior painting typically costs $6,000 to $14,000 for a 2,500 sq ft home with proper prep and two coats. The higher range reflects Massachusetts labor rates, coastal prep requirements, and premium materials needed for marine air exposure.
May through October is the optimal exterior painting window in Cohasset. Surface and air temperatures must stay above 50°F during application and for several hours after for the paint to cure properly. Late spring and early fall offer the most predictable conditions — lower humidity than July and August, and enough warmth for reliable adhesion before winter temperatures arrive.
Exterior paint lasts three to 20 years depending on siding material, paint quality, and climate. In coastal Cohasset, cedar-sided homes typically hold a quality exterior paint job for five to seven years with no major maintenance. Fiber cement siding with a premium acrylic topcoat can reach eight to 12 years. The biggest variable is prep — a job with full scraping, caulking, and priming always outlasts one where prep was cut short.
Yes. Power washing removes salt deposits, algae, mildew, and loose paint that would otherwise cause the new finish to fail prematurely. In Cohasset’s coastal environment, salt accumulation on siding is significant — especially on homes within half a mile of the harbor. Washing happens first, surfaces dry fully, and then prep and priming begin. Painting over a dirty or contaminated surface is the most common reason exterior jobs fail early.
100% acrylic latex paint is the top recommendation for coastal New England homes, according to Consumer Reports testing. Acrylic formulas flex with temperature changes instead of cracking, resist mildew and salt spray, and release trapped moisture rather than bubbling. Premium lines from Sherwin-Williams, Benjamin Moore, and Behr consistently rank highest in independent durability testing for resistance to cracking, fading, dirt, and mildew. For Cohasset homes, pair a 100% acrylic topcoat with a high-build, salt-resistant primer on all bare wood and repaired areas.
Exterior house painting in Cohasset costs $6,000 to $14,000 for most two-story homes — higher than the national average because coastal prep, premium primer, and quality acrylic paint are not optional in this environment, they are what separates a five-year job from a ten-year one. The painting window runs May through October, and the homes that hold up longest are the ones where scraping, caulking, and priming were done completely before the first finish coat went on.
