Does it matter who installs your basement insulation?

Basement Spray Foam Insulation | Evergreen Home Performance | Energy Efficiency Audits & Contracting | Maine

When it comes to insulation, there are plenty of choices. Where to start? What to use? Who to hire? The answers vary from house to house – and from homeowner to homeowner – but if you work with someone you trust, you’ll be in good shape.

Take basement insulation. At Evergreen, we recommend installing closed-cell spray foam on foundation walls to seal air leaks and insulate against heat loss. Plenty of contractors can spray foam, but we engineer and manage the whole project to deliver superior, safe results. We distinguish ourselves by:

  • Prepping the foundation walls before foaming. This often includes scraping and vacuuming dust, spider webs, etc. to ensure that foam adheres to the walls and performs its best.
     
  • Maintaining negative pressure in your living space during foam installation. Any installer should run a fan in your basement to vent the vapors generated during SPF installation. Evergreen takes this standard ventilation a step further, maintaining a pressure difference that keeps basement air downstairs to ensure that off-gassing does not compromise the air quality of your living space.
     
  • Running continuous ventilation for 72 hours after foam installation. We’ll continue ventilating your basement or crawlspace for as long as it takes for your spray foam to fully cure – up to 72 hours – to ensure safe indoor air.
     
  • Coating exposed SPF with intumescent paint. This time-consuming step is required by fire safety codes; we ensure that it’s done right.
     
  • Ensuring Efficiency Maine compliance. As an Efficiency Maine registered vendor, we deliver qualified improvements that earn you up to $1500 in incentives.

These details make a huge difference in the performance and durability of your improvements and in your family’s safety, so yes: it matters who installs your basement insulation. Contact us to start improving your home today.

We just finished a large project of air sealing and reinsulating our 1890s basement and attic which had been completely renovated 8 years ago but still felt cold and lacked proper energy assessment and corrections. We met with Justin in December and were very impressed with his knowledge, professionalism and communication skills and knew Evergreen was who we wanted to work with. Dave was our on hands project manager and was excellent. The office staff has been quick to respond and helpful as well when needed.

I used to spend winters in the bathtub because my house was so cold. This was my first winter roaming around my whole house comfortably. This even led me to decorate a little. My heating oil usage has been reduced by over a quarter: I rarely have to boost the thermostat because the temp stays at a constant. The Efficiency Maine rebates, together with the energy savings, make it affordable for me to pay for the loan I took out to finance the project. I do not worry about my pipes freezing.

The Evergreen Team did a fabulous job, well exceeding our expectations, In just over a week they transformed our very drafty, noisy 213 year old house into a snug, draft-free, quiet haven with warm floors! The team was prompt, did everything they said they'd do and more. We are thrilled!

We are so pleased with the work the team from Evergreen Home Performance did in our home. The project included encapsulation of our basement with a reinforced vapor barrier, installation of a sump pump, spray foam insulation on the walls and insulation of the heating duct work. Everyone at Evergreen was friendly and professional. The project was completed on time and in budget. Our home is much cozier and warmer since the project was completed.

Evergreen did an amazing job insulating our historic home. Their professional staff worked hard to ensure the tough areas in the attic were covered, and clearly communicated their progress. We are seeing the results with our discounted heating bills. Thank you, Evergreen!

From beginning to end – that is from the moment Justin McEdward stepped into our home to assess our energy conservation needs until the crew left – the Evergreen Home Performance process went absolutely smoothly. Justin made a thorough inspection and took pictures with an infrared camera. His proposal described the scope of work in detail, and he explained what we could expect the proposed work to accomplish. Our proposal was forthcoming within a couple of days, and Justin was available to discuss it and answer questions.

Evergreen did a fantastic job replacing 28 windows in our house. They were friendly, courteous, and very detail oriented. Brian did a great job planning, estimating and executing the project. Our energy use has dropped significantly since the work was done.

My husband and I bought a home on the water in Owls Head and decided to make the investment in Evergreen's recommendations for insulation. Brian Robinson spent 3 hours examining every nook and cranny before he made practical suggestions and explained them thoroughly to us.

A thorough inspection of our (older) house and its energy needs. Competent and personable work crew.

Jacob Watson

From start to finish, our experience was incredible. Justin was extremely helpful. The crew was fast, friendly, and efficient. And most importantly, our home is WAY warmer and our heating is less costly. I'd highly recommend evergreen to anyone looking to upgrade their home!

I never leave reviews, but had a great experience with Evergreen and wanted to spread the word! In short, we worked with them to insulate our roof this winter and have noticed surprising immediate results. The constant ice dams I have wrestled with are completely gone, and the home is noticeably more comfortable. It's a little too early to tell if our oil bill is going to reduce, but I imagine we will see an impact there as well.

We initially contacted Evergreen through Efficiency Maine for an energy audit, which was conducted promptly and professionally by Justin McEdward, one of their Energy Advisors who is BPI-certified. After a thorough inspection of our newly purchased home, Justin explained in great detail what we needed and did not need. It was agreed that Evergreen would remove all of the existing attic insulation, which was not adequate, and replace it with blown in cellulose, to a rating of R-60.

I had gotten estimates from several other companies, but Evergreen was in another league entirely with their professionalism. If you want the job done correctly, I couldn't recommend this company enough.

Thorough, smart, informative, integrated, and communicative -- that's how my experience was with Evergreen even with the covid interruption midstream. The team picked up where they left off, insulated basement and air sealed attic and knee wall in 100' temps under the eaves! This business group was a pleasure to work with.
