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.

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

Jacob Watson

This team of individuals was professional at all times. They set up barriers that kept the dust at a minimum. They conducted an air flow audit and cut the draft circulation from the outside in half by sealing cracks. They hauled out the old insulation and replaced it with blown in insulation with an R - 60 Value. They also did the rebate paperwork so that I could get my $1500.00 rebate from the state of Maine. I highly recommend Evergreen Home Performance!

We had Evergreen come out to our tiny old (100+ year old) house to see what they would recommend for decreasing our carbon footprint, saving money, and increasing our comfort in the cold season. Richard and Bryan were great to work with, patiently answering our many questions and walking us through multiple options. We could only afford to tackle a few areas this year; we ended up replacing some windows and having them weatherize the entire house.

Awesome company. It was a few years ago that they did the audit and then we commissioned them to do the work. We subsequently sold our house and moved to South Africa, but their level of service and expertise will live on.

Odette Brown

I would recommend Evergreen wholeheartedly because of their professionalism, their follow through, and thoughtful project planning.

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.

First we have Evergreen do a BIG project worth about $20K (windows, basement, insulate & rebuild an entire wall, a door, attics, and air sealing). They were so great we had them come back later when we decided we did want to do our other door. They are professional and do great work. They take care of your home and are trustworthy, and on top of all that friendly! I highly recommend you call them!

We just finished a large project air sealing and reinsulating our 1890s basement and attic. It 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.

Update 12/2018: Evergreen has completed Phase II of my house (insulating and installing air/moisture barrier on exterior walls, replacing old windows) and now that heating season is upon us, the difference is astonishing. The house is tight as a drum and so easy to keep warm. Worth every penny. Thank you all! Working with Evergreen was a positive experience from start (no charge energy audit) to finish (a MUCH more comfortable home). Brian Robinson spent a lot of time with me on the audit, explaining clearly what he was finding in my ca.

We absolutely loved our experience with Evergreen. The team was incredibly kind, professional and great to work with. We're very impressed with the quality of work of the Evergreen team and how easy they made everything! Our house had barely any insulation ahead of this project and the results are amazing. Insulating the attic, walls and basement with Evergreen allowed us to tear a 50-year-old furnace, ductwork and oil tank out of the basement and now heat the home with new heat pumps. Evergreen also added 100 sq ft of clean, new storage space to the attic!

Evergreen Home Performance shows its expertise from start to finish. Evergreen did three house projects in winter/spring/summer 2020 for me, attic insulation, crawl space under a porch insulation, and basement foam/vapor barrier. From my initial discussion with Bryan, I understood the reasons for choosing different types of insulation, the associated costs, and time estimates. Evergreen scheduled in advance, came when they said they would, and the crews were highly professional in their work and demeanor.

Iris S.

Evergreen listened and produced a thoughtful evaluation, proposal and comprehensive plan for our attic and basement. They exhibited excellent workmanship, teamwork, and came back as planned after the completion of the job to test the outcomes. Their overall performance as insulation and home improvement contractors is truly outstanding and we highly recommend them.

Our house still the most efficient home we’ve ever lived in. And we have you folks to thank for that! A special howdy to Brian Robinson please!

Last week, my oil company asked if we were using some other kind of fuel because our usage was so much less than they had expected We are very happy with the results; the house is much more comfortable
