"We moved into our house in the winter and found out that the 70 year old insulation was quite deteriorated and moldy in the fall. We decided to have the old insulation removed so that we could cut down on heating bills and get rid of the smell. I contacted several companies and interacted with Joe from Good Life as the salesperson. He was kind enough to come to our house twice as the scope of the project changed. Both times, he drafted the proposal right at the end of the visit. His professionalism and the quoted price convinced us to go with Good Life Energy Savers. On day 1, the first crew came to remove the old insulation from the attic and used open cell spray foam to insulate the basement rim joists. On day 2, a second crew came to apply blown-in fiberglass insulation in the attic. Please note that the material they use is not irritant at all. Both crews worked really hard and cleaned up very well after they were done. I was especially impressed with the job 1st crew did to remove the old insulation from the slopes on a cathedral ceiling. My only minor complaint is regarding the patch in the ceiling at the end of the job. The guys used paper tape and there were bubbles all around. I guess they were very tired at the end of the day. Initially, I was planning to paint the room myself to cover the patch. But after removing the paper tape (due to bubbles) and using fiber mesh tape and joint compound, I figured I wouldn't be able to smooth the edges of the patch perfectly and hired a professional. Overall, it is a great company that provides quality job at a reasonable price. With the new insulation, the furnace runs much less frequently and I am pretty sure the job will pay for itself very in a few years."

"Easy company to work with. In our large crawl space a few spots were missed. One call and the crew was back in 2 days to do touch up. Note that this was difficult work-lying on your back spraying above you with respiratory & eye protection so to miss a few spots might be expected as well as how insulation expands. They did great job removing old batt insulation Filled w mouse poop"

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

Insulation FAQs, answered by experts

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures.
