"I had called Insulation Pros for an estimate with very short notice as well as two other companies. Conrad was the second person to give me a detailed estimate also was more then pleased to come out to my house and write me a real in hand quote. He was on time and very informative on the project. The following Monday the 2 professional men came to my house and did the job that I was promised and within the time that was allotted. Cleaned up and was off to the next shortly after seeing if I was pleased with the job. These guys are awesome. I do recommend Insulation Pros to anyone thinking about getting insulation done.
Thank you and all your staff.

"We had radiant barrier insulation installed insteads of blown in insulation. It was laid in the attic rafters, upon the completion of the job the service provider could have done a better job of cleaning up. He also left some marking on our cabinet. When the gentleman came over to give us an idea of what radiant barrier is we never knew when he would be there, they gave us an estimate but then upon completion we wrote a check, but never received a receipt of payment, or work order showing completed work. All we had was the gentleman sign the estimate that we had been given two weeks prior to the job. And the installer did not have any paperwork saying that he did the job. But we had him write that on the estimate. I would expect more professional paperwork."

"They were fantastic! From Elaine who took my call to Eric who came to the house, the professionalism, courtesy, responsiveness and service I got from Diamond was top notch. On one of the hottest days of the summer when our A/C went out (naturally), they went out of their way to get to me ASAP. Then when Eric came to do the service call, he was efficient and thorough and very clear about what he was doing and why.
I couldn't recommend this company more.

"Outstanding quality, especially in custom designing what is called a cricket flashing to go around a chimney, the corner of the house and a valley which all converged at the same point.
Once the old roof was off, we found approximately $1700 worth of dry rot that needed to be replaced. I felt the crew, particularly Mike Gibbs, did an excellent job of helping me understand the problems and then pick the best solutions to correct the problems. Their price for the extra work was extremely fair and the again the quality was excellent. We ended up replacing all of the fascia boards and the final result looked better than the original (and it was Mike's idea of how to do it).
In addition to the roof, they blew in some additional insulation in my two level attic to bring it up to an R-38 rating. There were two spots that I felt might have been just a bit short and they returned promptly and filled in those spots by hand ... no questions asked.
For what it might be worth, the building inspector, when I told him the work was done by Brazil, sort of muttered under his breath "Good, they do it right" as he climbed the ladder to look at the roof.

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
