"Master Attic removed my old and rodent infested insulation, thoroughly cleaned out all the junk in my attic, vacuumed all the dirt, debris, and rodent feces, sealed all air leaks, installed rodent-proof cages around any entry points to the attic, sanitized the entire attic space and installed new insulation throughout. Francisco and his crew were fantastic! Great job by Master Attic! Thank you!"

"In the attic, we had wooden slats that covered the floor so they had to go under the floorboards. Although we were told by the salesman that there would always be a person on the other side of the wall to check for problems, the second guy was not watching and they blew a hole in the ceiling of the bedroom ( see pictures). They assured us that they would fix the hole, spackle it and repaint the ceiling. They did spackle the hole but only painted the area that they fixed - not the whole ceiling. And they did a lousy spackling job. We had to get someone else to smooth out the spackle and repaint the ceiling. We could have pushed to get them to fix the ceiling but it was late on the last day and we wanted the job done. As for the gel on the outside, the truck broke down due to the heat of the day and it took 3 days to finish the rest of the job including fixing the ceiling and the inside walls. Although the salesperson, did a first investigation of the house and said it could all be done from the outside, the workers found that one bedroom was covered in concrete so they had to drill from the inside of one of the bedrooms leaving many holes to be spackled. This time it was not so bad and we were able to sand and repaint that bedroom. But the workers could have done a better job of cleanup of the sparkle. It was all over the baseboard and the rug and we had to use rags to clean it up. We realize that things happen. And maybe we were too hopeful based on the salesman's pitch. But we would rather have had the salesperson tell us the truth about the possibility of drilling holes in the inside of the house even though he did a thorough inspection. All in all, we are hoping that insulating our house will save us a lot of money in heating costs. The manager was very accommodating, we saved some money by paying with a check vs a credit card. The workers were very nice and the lead person was very knowledgeable. Any renovation is stressful. We would probably recommend them because now we know what to expect. This company was recommended to us by a number of people. We have no doubt that the product itself is excellent. For that reason, we expected it all to go smoothly. It did not. Everything that could go wrong, basically did. It all got fixed but ... We did not plan for a hole in the ceiling, the truck breaking down and go into the shop to fix the problem with the gel overheating and not coming out of the hose fast enough, the concrete in one of the bedrooms that meant that all the holes had to be drilled on the inside of the bedroom and we had to repaint. So for those reasons, we are giving them a rating of fair. We hope your experience will be a lot better than ours !!"

"All punctual, polite, professionals, hard working, amicable, Alfredo Sotto was our installer and his crew member Ernie did an exemplary, and they were really neat. The co-owner Jeff who personally came to our house was informative. Phil gave the initial presentation on Monday May 8 he was very detailed and very convincing."

"Larry Doyle was a joy to work with.  He was originally one of the dry wall professionals who had given me an estimate on the ceiling repair to submit with my claim to the washing machine manufacturer, and I had been impressed with him then.  I waited a while before actually getting the ceiling fixed, but had decided to use Larry from my experience with him in preparing the claim.  I'm glad I did. He was prompt, highly professional, and did an excellent job.  Also, his price was very reasonable.  Further, he returned my phone calls quickly and was always responsive.  I would certainly use him again.

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"

I bought a ranch house that has been closed for a while, allergy issues got worse when I run the A/C unit. l look around for a good price and availability. They were quite busy but they helped me on a Sunday, that was perfect for me. Costumer service excellent from start to end , Daniel was very efficient, moving around very quick but meticulously cleaning each vent. They used shoe covers and vacuum any residue. I can tell the difference now. Great  service, I will use their service again.

"It went great. We had our system installed in 2011. It took two days and we haven't had water in our basement and crawlspace since. Right Way Waterproofing did what I thought could never be done. They follow up every year and clean and check our system. I couldn't be happier. It has been the best home investment I ever made."

Insulation questions, answered by experts

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.
