"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

Insulation questions, answered by experts

Build a routine around the four distinct seasons to maintain your insulation service. In late fall, check attic hatches and basement rim joists for tight seals before the Manchester winter begins. During early spring, inspect your attic for ice dam water intrusion. In early summer, monitor basements for condensation driven by high humidity. Finally, conduct a draft check in early fall to ensure your NH home remains fully sealed.

Helpful?

The local climate and your home's age heavily impact insulation service in Manchester. The region's harsh freeze-thaw cycles and heavy snowfall stress materials over time. Older homes feature balloon-frame construction and lack original moisture barriers, making proper air sealing essential. Additionally, projects must meet New Hampshire's strict energy codes for Climate Zone 6, which require higher R-values and precise vapor barrier placement on the interior side of walls.

Helpful?

Blown-in cellulose or fiberglass works best for attic insulation service, easily meeting the high R-value requirements for NH. For basement walls, closed-cell rigid foam board provides essential moisture resistance against wet spring conditions. Use closed-cell spray foam to seal rim joists and attic bypasses effectively. In older Manchester homes, dense-pack cellulose is ideal for retrofitting wall cavities. Always install a heavy-gauge polyethylene vapor barrier over crawl space floors.

Helpful?

Completing insulation service provides immediate relief from winter drafts and prevents destructive ice dams common in Manchester. During the first season, you experience improved indoor comfort and measurable heating reductions. Over the long term, proper insulation prevents chronic moisture damage in older basements and extends the lifespan of your HVAC system. These upgrades also increase your home's market value while meeting New Hampshire energy efficiency standards.

Helpful?

Keep a moisture meter and hygrometer available to track humidity levels after completing insulation service in Manchester. For inspections, use a bright flashlight, a thermal leak detector, and an inspection mirror. Always wear an N95 respirator, protective coveralls, and gloves to stay safe. Finally, keep low-expansion canned spray foam, weatherstripping, and vapor barrier tape ready to patch small gaps that emerge after harsh NH winters.
