"It was great to work directly with the owners!! They were responsive to all of our questions. They came in, did the work, cleaned up and except for the excellent spray foam job that they did you would never have known they were here. Would hire again when needed."

"The owner of the company did my estimate, and was wonderful in explaining things, and at no point did I feel I was being up sold or steered in any direction. The two installers were pleasant, quiet, worked clean and quickly. They left the house as clean as it had been when they arrived, and I am already appreciating a change in the air temperature in my upstairs. I would completely recommend Superior Insulation."

"Mark was very professional and gave a complete explanation of the estimate and work involved. while only one man showed up on the date scheduled for insulation, he completed the exterior walls foam insulation work including the interior basement rim in the day as promised and was very courteous and thorough. I have noticed quite an improvement in the warmth of my home and especially since we have had 2 very cold weeks since Christmas. negative degrees! I am very pleased with the company and the work."

"Scott arrived punctually for our first meeting and thoughtfully and thoroughly analyzed our problem (mold on peak of cathedral ceiling).  He listened carefully to our thoughts and explained his analysis clearly and completely.  He provided us with examples of similar situations he had addressed, successfully, in the past. He also showed us photos of his previous work. He spent over an hour with us, answering all questions and outlining his processes.  

After we agreed to have him do the job, he provided an extensive written contract for the work.  Our lawyer reviewed the contract and made several suggestions.  Scott quickly adjusted the contract to address our lawyer's concerns.  He scheduled the work promptly and it was completed in the agreed upon time frame.  We asked for the new electrical circuit to be labelled, and Scott took care of this without additional reminders, although I don't believe this was part of his usual service. There were no add ons to the bill.

After the work, Scott responded to questions and promised referrals to mold remediation services if required.  We've called him several times with questions, and he has always responded promptly with useful answers.

We have been totally satisfied with Scott Knapp and Rfactor from start to finish and would recommend him enthusiastically and without reservation to anyone with a similar problem."

FAQs for spray foam insulation projects in Waterloo, NY

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
