Ecotelligent installed spray foam insulation at my house. They encapsulated two crawl-spaces and sealed the rim joist in the basement. Steven and team worked quickly and left very little sign that they had been in the house (besides the spray foam!). The process went pretty much how it was described ahead of time. Towards the end of the work day, I had a question about the door to the crawl space, and Steven carefully explained the options and we agreed on a solution that he implemented immediately. Ecotelligent also measured the air leakage in the house envelope before and after the work; the test showed that air leaks were reduced by 17%. We expect our floors not to be as cold this winter now that the crawl spaces are insulated. Thanks Ecotelligent!
