"EZ insul did a great job removing old fiberglass under an addition of our home. Due to rodents we needed this removed and replaced swiftly. Jake communicated quickly and effectively. This allowed us to continue with our other projects. Additionally the EZ insul team rolled out drop cloths to keep everything clean and were very respectful of my home."

"Prompt estimate, called back every time I reached out, showed up on time, insulated our addition as specified and finished early. Came back to touch up something that got messed up by another contractor and did not complain or charge me. Rare experience in today's world with contractors. Would have given six stars if I could."

"Fabulous job! We area already see the difference with the insulation through Mass Save about 25%! Mark and his crew were very professional, courteous, and really nice guys. Garrett did a great job with estimating and made the process very easy and recommended additional measures to explore. I highly recommended Green Collar!"

"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

Insulation questions, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

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.

There are many ways to keep your house cool without central air. In fact, ductless mini-split AC systems are a solid alternative to central AC for situations when you can’t install ducts in your home. If you’re looking for a more budget-friendly cooling solution, consider using window AC units or portable air conditioners.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

While insulation is required for all exterior walls in a house, it is not typically required for interior walls. Local and state building codes mandate that new construction homes have adequate insulation in exterior walls and ceilings to suit the local climate.

However, there are several benefits to adding insulation to interior walls. It is excellent for sound-dampening between rooms and can help with temperature control by maintaining a regulated temperature in specific rooms and lowering heat transfer between adjacent areas. Insulating interior walls can also contribute to the overall energy efficiency of your home.
