Exterior Painting

Exterior painting in New Brunswick is both a cosmetic upgrade and a critical maintenance task. The Maritime climate is exceptionally hard on painted exterior surfaces — NB experiences over 100 freeze-thaw cycles per year in many areas, receives 1,000-1,400 mm of annual precipitation, and coastal communities from Shediac to Saint Andrews face salt-laden winds that accelerate paint breakdown. Without a sound exterior paint film, wood siding, trim, and fascia absorb moisture that leads to rot, mould, and structural deterioration far faster than in drier inland provinces. Professional exterior painting in NB starts with thorough preparation: power washing to remove dirt, mildew, and loose paint; scraping and sanding peeling areas down to a solid substrate; caulking gaps around windows, doors, and trim joints where water entry causes the most damage; and priming bare wood and patched areas with a high-adhesion exterior primer. The painting window in New Brunswick is relatively short — ideal conditions require consistent temperatures above 10 degrees Celsius with low humidity, which typically limits exterior painting to mid-May through mid-October. Experienced NB painters plan around this season and avoid painting when rain is expected within 24 hours. For a typical New Brunswick two-storey home with 1,500-2,000 square feet of exterior surface, expect to pay $4,000 to $10,000 for a full exterior repaint including preparation, two coats of premium acrylic latex paint, and trim work. Homes with extensive wood detailing, multiple storeys requiring scaffolding, or significant prep work from neglected maintenance will fall toward the higher end. Acrylic latex paint is the standard choice for NB exteriors — it flexes with the wood through temperature changes, resists cracking better than oil-based paints, and allows moisture vapour to escape from within the wall assembly, which is essential in Maritime construction. Premium exterior paints from manufacturers like Benjamin Moore Aura Exterior or Sherwin-Williams Duration are worth the 30-40% price premium over builder-grade products because they retain colour and adhesion significantly longer in NB conditions. A quality exterior paint job should last 7-10 years in New Brunswick before requiring recoating.
