GUTTERS • July 05, 2024 • 1 min read
I’m John Dewitt, owner of Dewitt Construction. With decades of experience, I’ve seen how neglected gutters can lead to costly damage. Clean and inspect them at least twice a year—especially in spring and fall—to prevent clogs, leaks, and overflow.
Ensure downspouts direct water away from your foundation, and check for sagging or leaks after storms. Gutter guards can also help reduce buildup.
If you spot pooling water or stains around your home, it’s time for a professional check. Dewitt Construction provides full gutter and roofing maintenance to keep your home protected year-round.

ROOFING • August 12, 2024 • 2 min read
At Dewitt Construction, we’ve seen how small roofing mistakes lead to big problems. Avoid these common issues to protect your home:
Skipping inspections: Catch leaks and damage early with seasonal roof checks.
Using cheap materials: Invest in durable shingles or metal roofing built for New York’s weather.
Poor ventilation: Proper airflow prevents moisture, mold, and premature wear.
Ignoring flashing and sealant: These protect vulnerable roof areas—keep them maintained.
Hiring inexperienced contractors: Always trust licensed professionals for lasting results.
Your roof is a major investment—protect it with quality materials and expert workmanship from Dewitt Construction.

SIDING & EXTERIORS • September 18, 2024 • 3 min read
Planning an exterior upgrade? Start by checking for signs of wear—peeling siding, roof stains, or water damage—to set your priorities and budget.
Choose materials suited to your style and climate, like vinyl siding for easy upkeep or metal roofing for long-term durability.
Before work begins, schedule a consultation to align on design, costs, and timeline. With Dewitt Construction, you’ll get a smooth process, clear communication, and quality craftsmanship from start to finish.
