The best time of year to paint a house exterior in North Jersey

Paint needs warmth and dry surfaces

Exterior coatings cure properly when the surface is dry and the air stays reliably above the manufacturer's minimum temperature — usually around 50°F for most exterior products, though some low-temperature paints go lower. North Jersey gives us a comfortable window from roughly late April through October.

The bigger issue isn't the daytime high, it's the overnight low and the dew. A siding surface that gets damp overnight can leave a fresh coat looking blotchy or slow to harden, which is why we watch the forecast rather than the calendar alone.

Spring: prep season

Spring is when winter damage shows up — peeling on south-facing walls, cracked caulk at window trim, wood rot at the bottom of corner boards. We often do the repair and scraping work in spring and coat once the wet weather settles.

Summer and early fall: the sweet spot

Long, dry days let us wash, scrape, prime and coat without stopping. This is also our busiest stretch, so if you want a specific month, it's worth calling well ahead rather than the week you want to start.

Late fall and winter

Once nights sit near freezing, exterior painting becomes a gamble. That's a good time to move indoors — interiors, cabinets and trim are unaffected by the weather, and it keeps your project moving instead of waiting for spring.

What we do before a single coat goes on

Prep is most of the job. On a typical exterior we:

• Wash the surface to remove dirt, chalking and mildew
• Scrape and sand loose or peeling paint back to a sound edge
• Repair or replace rotted wood and re-caulk joints and trim
• Spot prime every bare area before the finish coats
