"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

"This company was extremely reliable and worked very fast to get the job done. We used them to renovate an apartment for rent and they were honest with their prices and even suggested options to save us money. We would definitely utilize them in the future and recommend them. I wish I had taken before and after pictures to show what a great job they did. Also, we were really impressed that the contractor sent us pictures and contacted us every time they completed anything."

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...

Another Happy Homeowner!

"The experience of having roof replaced went exceptionally well despite taking place during the hottest days of the summer. My salesman was extremely knowledgeable and provided me with all the details I needed to know the quality of the materials and installation. The final results were even better than anticipated and I am confident I will enjoy my home for years to come."

"I called Restore You and the owner Art Sulik came to my home at my convenience. He surveyed unerdneath my home and found mold on the floor structure and moisture and water on the ground. He removed the existing insulation, cleaned the wood with hydrogen peroxide product, followed through with an anti microbial. After everything dried they Hepa vac the wood to remove any mold spores which are allergens. Then fogged everything with Timbor fungicide Disodium Ocyabotate tetrahydrate (boron). The foundation walls inside the crawlspace were painted with Dry lok extreme, a waterproof paint. A vapor Barrier 6 Mil was added to the ground. His work was exceptional! I was very pleased. I highly recommend Restore You for any moisture, mold or water problems."

Insulation questions, answered by experts

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
