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 Portland-area 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.

Yes. Our Portland office serves Greater Portland and the surrounding communities south through York County and north through Brunswick and Bath. A home energy audit includes blower door testing, thermal imaging, and a full assessment of your home’s insulation, ventilation, and moisture risks. It’s the right first step before any insulation or air sealing work, and it qualifies you 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 Portland homes benefit from a combination of both, depending on moisture levels and foundation conditions.

Yes. Southern Maine’s heavy rain, clay soils, 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 indoor air quality and reduces long-term repair costs.

Yes. Evergreen installs spray foam insulation in Portland 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 rebates are available statewide, including Greater Portland. Evergreen helps Portland homeowners identify which upgrades qualify and handles the rebate paperwork after the project is complete.
