"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job!
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...

"I recently needed attic insulation installed; I reached out to several companies for quotes. Dallas came out right away and gave me a complete honest rundown on my issues. I had just purchased this home only to understand my situation was dire, he gave me a great price and even offered to change his schedule to get this project done quickly. He showed up within just a few days and did an incredible job, his team is very professional and even installed a new bath fan i needed. Thank You Windsor Insulation company, my house is noticeably warmer and I couldn't be happier. Great Job and I recommend Windsor Insulation 100%"
