"THESE GUYS ARE AMAZING! Our new porch looks perfect!!!! They got back to us very quickly, and after we agreed on the project spec's amd pricing they got right to work. Our old porch was down and our new one was up in just a little over a week. They were even able to repair our leaky side roof! These guys were friendly, professional and very neat. They also offered us financing options which was to have. I would recommend these guys to anyone looking to have some home improvements done! We will totally be using them again!!!"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

"Overall, excellent. We did encounter a few problems with the spray in wall insulation since the original sheet rock was just nailed in. A few sections bowed into the room. This is actually pretty common with old houses. The problem was quickly corrected, the walls properly secured, the insulation reinstalled (blown in) and the job completed. In modifications to a home, it is not always the problems you encounter, it is how you deal with them. Advance had the problem identified with a resolution that was completed within a day. Very pro-active!"

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

"From the moment we met nick we felt comfortable. After my gf got taken for money from a contractor we were a little hesitant on trusting anyone again.. Nick gave us a quote for the job that we were very happy with. And insured us we would be very happy. And wow were we, nicks crew was amazing , friendly and cleaned up everything when do e. Can't say enough about nick and his team. This is how a business is supposed to be run. Don't even bother calling anyone else. They did an amazing job on our building and more importantly? Welcomed us like we were family during the process... 100 thumbs up. Chris and Christina"

Insulation FAQs, answered by experts

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
