Get answers to common questions about insulation services in Lewiston, Maine.
For Lewiston's climate (Zone 6), achieving a high R-value is critical. We typically recommend air-sealing combined with blown-in cellulose or fiberglass in attics and dense-pack cellulose in walls. Spray foam is excellent for sealing rim joists and crawlspaces to prevent the icy drafts common in our older homes. The right choice depends on your home's age, construction, and existing insulation.
Costs vary based on the project scope and material. For a standard attic insulation upgrade to R-60, Lewiston homeowners can expect a range of $1,500 to $3,500. Whole-house projects (attic, walls, basement) often range from $5,000 to $12,000+. It's important to get a detailed, in-person assessment, as many local homes have unique challenges like balloon framing or knob-and-tube wiring that affect pricing.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is optimal for attic work. Scheduling in these shoulder seasons also ensures your home is prepared before the deep cold of a Maine winter sets in, and you can often avoid the busy winter rush for contractors.
Yes, Efficiency Maine Trust offers significant rebates for homeowners who improve their insulation to meet specific R-value targets. These rebates can cover a substantial portion of the project cost. Additionally, some Lewiston residents may qualify for low-income weatherization assistance programs. A reputable local contractor will be familiar with these programs and can help guide you through the application process.
Not entirely. Insulation resists heat flow, but air leakage is the primary cause of drafts and high heating bills in Maine's older housing stock. A comprehensive approach is essential: we must first perform a thorough air-sealing of gaps, cracks, and bypasses in the attic, basement, and around windows/doors. *Then* adding insulation is maximally effective, creating a tight thermal envelope that keeps heat in during our long winters.
