Common questions about Rockland insulation and waterproofing

If your home feels drafty, your heating bills are high, or some rooms are much colder than others, your attic insulation may be underperforming. Many Rockland homes still have low insulation levels or hidden air leaks that let heat escape. An energy audit with thermal imaging can show where insulation is missing or compressed and whether air sealing is needed before adding new insulation.

A home energy audit in Maine includes blower door testing to measure air leakage, thermal imaging to locate heat loss, and a full walkthrough of your home’s insulation, ventilation, and moisture risks. You’ll receive a clear report and recommended upgrades to improve comfort, lower energy use, and qualify for Efficiency Maine rebates.

Crawl space encapsulation seals the crawl space with a vapor barrier and insulation to block moisture, air leaks, and cold floors above. Crawl space waterproofing focuses on managing liquid water with drainage systems, sump pumps, or exterior grading. Many Rockland homes benefit from a combination of both, depending on moisture levels and foundation conditions.

Yes. Coastal Maine’s heavy rain, high water tables, and older foundations make basements especially vulnerable to moisture. Basement waterproofing helps prevent water intrusion, mold growth, musty odors, and structural damage. It also protects your home’s indoor air quality and reduces long-term repair costs.

Yes. Evergreen installs spray foam insulation in Rockland for basements, crawl spaces, rim joists, and other hard-to-seal areas. Spray foam creates both an insulation layer and an air barrier, helping reduce drafts, moisture, and heat loss in one step.

Yes. Efficiency Maine offers rebates for qualifying insulation and air sealing projects. Evergreen helps homeowners in Rockland identify which upgrades qualify and guides them through the rebate and financing process to make improvements more affordable.
