"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"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."

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

"I didn't end up insulating my home with Coleman or any other company (in the end I didn't need to) but am leaving a review about their responsiveness and professionalism, which was superb."

"MA Design is my goto for any remodeling work that I need. I have had several projects over the years and have been very satisfied. This year we did reconstruction windows, interior and exterior painting, and transformed dated bookcases. Re-construction/new construction windows can be a challenge for an older home. MA Design worked to level the windows, and ensure sealing. These windows gave my home a facelift. The success and high level of customer satisfaction is a result of our collaboration. We discuss my desired outcome, and review options to achieve the result, and remain in budget. They provide a quote that itemizes the work. We review each item, so that we are on the same page, and I have no assumptions. Some highlights: * Protecting the surrounding interior environment * Trusting - I can leave with peace of mind * Providing recap of each days work * Discussing next day's work activities Great job guys, look forward to next project."

"I called these folks to get a quote on removing vermiculite from an attic. They were pleasant and prompt. They informed me about the Zonolite Attic Insulation Trust which can, provide significant reimbursement for the removal and took and sent in a sample to get tested to see if it qualified for reimbursement. All of this before I even got an estimate. When I asked them about some mold they were gracious enough to suggest I find a firm that could do both and suggested a contractor. In the end I didn't use these folks based on comparison quotes but based on their professionalism, honesty, and knowledge I'd highly recommend them to anybody that needs this kind of work."

"From the very beginning and throughout the process, Leo explained everything that we would need to know about roofing, the product and the process. Leo is professional and meticulous. The job was completed in one day with a crew of men who attended to every detail. Leo was present throughout the day overseeing the work. The clean up was done efficiently and the yard looks great. But most importantly, the roof looks fantastic. A job well done!"

"Vendor was able to complete and interior framing project in record time and was able to do a patch work job on an area of my roof that had been damage by a falling tree. This was completed in a 24 hour period. While on site, I requested advice on future siding work that needs to be done later this Spring. Vendor was very helpful and I will be using them to do the work required."

"I received an emergency call from my tenant that the apartment door would not lock. I checked Angie's list for a local handyman and called JR maintenance for assistance. They were busy with another another job 25 miles away, but went out of their way to diagnose the problem the following evening. Usually I would perform the work, but was out of state on business.

JR was punctual and actually repaired the problem without a service charge. They are now saved to my phone contacts for future work this coming year."

Insulation questions, answered by experts

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.
