"I've been trying to find an expert in insulation for months to come out and tell me out to properly insulate around a removed chimney and Comfenergy was the expert I needed. Even though the insulation part of the job was too small for Comfenergy (wasn't above their minimum quote value) they were happy to give me their expert advice and I appreciate the time spent as I now know what to ask the roofing contractor to do in order to insulate this correctly. Thanks!"

"I am very pleased with how my attic insulation project turned out. when the company came to my house to give an estimate they evaluated my current insulation, told me what I needed to bring my home up to the current standards for attic insulation. (r49) more importantley they told me what I didn't need. I highly recommend this company for your insulation project."

"Arrival was right on time! i needed insulation in 2 attics. They ( Enrique, Jonathan and Walter) protected my carpet, floor and furniture. They worked steadily from 8 am until 4 pm. They were polite and did an excellent job. Luis came to inspect the work done and came the next morning to insulate/seal the door in a bedroom going to one attic and did not charge any additional fee. I feel warmer already! Hope that extra money spent on high electric and gas bills will warm my wallet and bank account! I highly recommend this company!"

"From the start of the estimate with Jon to the insulation project with the Team Leader Carlos, the project went well as expected. Jon was very professional and knowledgeable. He did not try to up-sale services I did not need, and I appreciate his honesty. Jon went over the appropriate insulation for the attic and the garage ceiling to bring our home to a comfortable level. Carlos and his crew did a great job communicating with me while performing the insulation. Carlos immediately notified me of a leak he discovered from the attic fan and temporarily paused the work on the attic and moved to the garage ceiling insulation while I addressed the leak. As a customer, the only comments/suggestions I would give to the crew is: (1) make sure they keep their tools and materials off the lawn (2) make sure the plastic wraps from the materials they use and trash does not get blown away to the neighbor's yard/driveway, and finally, (3) ask the homeowner which bathroom the crew can use while on-site. Overall, I am very happy with Comfenergy and their service. In fact, I have already recommended them to a curious neighbor."

Insulation questions, answered by experts

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency.
