"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!"

"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

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Garage doors that are not insulated can be a major source of heat loss. That’s why it’s essential to winterize your garage door with insulation and weather stripping to prevent heat loss and keep it warm more easily. Consult a local garage door installer if you need help determining the cause of your garage losing heat.
