"I have had Mass Energy Lab Insulation insulate my garage, my attic, my basement as well as the walls of my entire home over the last 5 years and what has impressed me the most is that they have been consistently getting better. First dealing with Mo and now with Josue over the last two years, its always been first rate. Wish they did more than insulation, I would certainly be seeing more of them."

"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

"We are beyond pleased with the services provided by Hughes. Their workers were exceptional. They showed up on time, were polite, explained the process as the job progressed, answered all our questions and were extremely respectful of our home. They cleaned up as they went along and were very quiet. This was not an easy job. The slant roof and small space must have made this job all the more challenging because you can't stand up straight. The guys still managed to get it done within the time frame they had committed to and never once complained. The works looks very professional and our home feels so much more comfortable than it was before we insulated."

"We called Sean with New Found Construction and he personally came out and gave us a quote to insulate our attic and the ceiling in the unfinished part of our basement. His price was far more reasonable than other quotes we had gotten and seemed to offer a more complete job. It all came out AWESOME and we can absolutely feel a difference in temperature in the house (especially my office above the unfinished basement which used to be an icebox in the winter) and the heat kicks on a lot less. We have already planned to have him and his crew do other jobs around our house. Two thumbs way up!!"

Insulation FAQs, answered by experts

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.
