Interior Painting in NH: What to Expect, What It Costs, and What to Ask

A fresh coat of paint is one of the highest-return-per-dollar improvements you can make to a home. It's also one of the most variable in quality — and the difference between a job that looks good for two years and one that looks good for ten comes almost entirely from the prep work, not the paint.

What Good Prep Actually Looks Like

Prep is where most painting contractors cut corners, because it's labor-intensive and invisible in the final product. A thorough prep process for interior painting includes:

• Cleaning surfaces — grease, dust, and residue prevent paint from bonding properly
• Filling holes, cracks, and imperfections with the correct compound for each substrate
• Sanding smooth — by hand where necessary, not just a quick machine pass
• Addressing any moisture damage, efflorescence, or staining before priming
• Caulking all joints between trim and wall, at base moldings, around window and door casings
• Priming bare drywall, patched areas, and stain-blocking where needed
• Fully masking and protecting floors, trim, fixtures, and furniture

A contractor who skips caulking, applies paint over unsanded patches, or uses cheap primer on bare drywall will produce a job that looks acceptable at completion and starts failing within a year.

Paint Selection

The professional-grade lines from Benjamin Moore (Aura, Regal Select) and Sherwin-Williams (Emerald, Duration) are meaningfully better than builder-grade products in coverage, durability, and washability. They cost more per gallon, but a premium paint applied correctly over proper prep will outlast multiple coats of cheap paint on inadequate surfaces.

Sheen selection matters too. Flat and matte finishes hide surface imperfections but don't clean well — appropriate for low-traffic ceilings and master bedrooms. Eggshell and satin are the standard for walls in living areas and hallways. Semi-gloss on trim, doors, and millwork provides durability and a clean, defined look. High-gloss is rarely used on walls in residential interiors, but works well on cabinetry when properly applied.

What It Costs in New Hampshire

Pricing varies by project complexity, surface condition, and contractor. Rough ranges for the NH market:

• Single room (walls only, good condition): $400–$700
• Full interior repaint, average home (1,500–2,000 sq ft): $4,000–$8,000
• Trim and doors throughout a home: add $1,500–$3,000
• Cabinet repainting (kitchen): $1,500–$3,500 depending on door count and finish type
• Rental turnover (one-bedroom apartment): $800–$1,800

Significant deviations from these ranges — in either direction — are worth asking about. A bid that's notably lower than others typically means less prep, cheaper materials, or fewer coats.

Questions to Ask Before Hiring

• What does your prep process include specifically — caulking, priming, sanding?
• What paint brand and product line do you use, and is it included in the quote?
• How many coats are in the quote, and under what conditions would you apply more?
• Are you licensed and insured in New Hampshire?
• Do you have references from jobs similar in scope to mine?
