"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"In the attic, we had wooden slats that covered the floor so they had to go under the floorboards. Although we were told by the salesman that there would always be a person on the other side of the wall to check for problems, the second guy was not watching and they blew a hole in the ceiling of the bedroom ( see pictures). They assured us that they would fix the hole, spackle it and repaint the ceiling. They did spackle the hole but only painted the area that they fixed - not the whole ceiling. And they did a lousy spackling job. We had to get someone else to smooth out the spackle and repaint the ceiling. We could have pushed to get them to fix the ceiling but it was late on the last day and we wanted the job done. As for the gel on the outside, the truck broke down due to the heat of the day and it took 3 days to finish the rest of the job including fixing the ceiling and the inside walls. Although the salesperson, did a first investigation of the house and said it could all be done from the outside, the workers found that one bedroom was covered in concrete so they had to drill from the inside of one of the bedrooms leaving many holes to be spackled. This time it was not so bad and we were able to sand and repaint that bedroom. But the workers could have done a better job of cleanup of the sparkle. It was all over the baseboard and the rug and we had to use rags to clean it up. We realize that things happen. And maybe we were too hopeful based on the salesman's pitch. But we would rather have had the salesperson tell us the truth about the possibility of drilling holes in the inside of the house even though he did a thorough inspection. All in all, we are hoping that insulating our house will save us a lot of money in heating costs. The manager was very accommodating, we saved some money by paying with a check vs a credit card. The workers were very nice and the lead person was very knowledgeable. Any renovation is stressful. We would probably recommend them because now we know what to expect. This company was recommended to us by a number of people. We have no doubt that the product itself is excellent. For that reason, we expected it all to go smoothly. It did not. Everything that could go wrong, basically did. It all got fixed but ... We did not plan for a hole in the ceiling, the truck breaking down and go into the shop to fix the problem with the gel overheating and not coming out of the hose fast enough, the concrete in one of the bedrooms that meant that all the holes had to be drilled on the inside of the bedroom and we had to repaint. So for those reasons, we are giving them a rating of fair. We hope your experience will be a lot better than ours !!"

"Highly recommend Koala insulation to anyone in need of insulation services. Matt was prompt, friendly and examined all options. During the day of sevuce, the installation crew showed up on time , examined the process, worked quickly and cleaned up after. Their prices and quality cannot be beat and its not easy to find high quality at such a price. Thank you!"

"This project started w/ my husband & I wanting to change out 3 windows. THREE. We'd gone thru the whole spiel w/ Anderson who wanted to swap out all our windows for an obscene fee. That was NOT what we wanted. After submitting an Angi request, Victory reached out. We set up an appt where they showed us the quality of their windows & also pointed out the poor condition of ours. We were immediately impressed. I'm talking energy efficient, virgin vinyl, break in resistant & MORE. We were sold but concerned about being appvd for financing. Kyle was able to find us a lender at a decent rate. He assured us the job wld go smoothly. Truthfully we were dreading the actual install because of the mess. Kyle assured us again that everything wld go smoothly. Install day arrived. We were told prior that it'd be an all day project. Understandable for 18 windows. A team of 4 arrived at 8:30, got right to work & were done by 3pm! And when I say done, I mean installed AND cleaned up. They thoroughly vacuumed the areas they were working in. I couldn't believe it. Now our windows are beautiful! No more mold. No more decay. No more stuck locks. What a total upgrade! I've never experienced such good service. We're looking fwd to finally being able to open our windows safely AND saving $ on heating & cooling. Money well spent! I highly recommend Victory Homes."

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.
