"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"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 !!"

"I reached Out to Mr. Alonzo on January 24th and he responded almost immediately that evening.He came out and inspected the project the following Friday morning and i had a quote that afternoon. Considering the work needed and the fact that it was a pick up of an already started project he was very detailed on the expectations and costs. His first crew was there the following Tuesday and i could immediately tell that Mr. Alonzos' people were very professional and knew exactly what they were doing. Within a week i was ready for paint in both rooms and i was extremely satisfied in the work his finisher Manuel was able to accomplish considering the deformations in the structure. Once he was done you could barely tell anything was amiss and once paint was applied the next day i was very pleased with all work. Next time i start a project Juan's company is first on my list"

"Their work and professionalism were top-notch. The inspection turned up problems in both the crawlspace and attic, but the attic problem is related to a roofing issue. Rather than do a "patch job" there that would have required re-doing in the near future, Restore You gave the honest evaluation that the roofing work needed to be done first so their remediation work would hold up. They will return when the roofing is done. In the meantime, they completed mold remediation and full insulation in the crawlspace, and even worked through the weekend to get the job done."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"



They arrived 2 hours early to which I had agreed. They were very pleasant and professional. They cleaned all vents and the returns where possible (wires inside prevented 2).

I think it went well..

"Mike came and did a thorough inspection of my crawlspace which was once home to a family of raccoons. CleanSpace came and cleaned and disposed of all of the soiled insulation and sanitized the space before installing new and better insulation . The work was done quickly and as described, I would recommend them for anyone in a similar situation!"

Insulation questions, answered by experts

Costs depend on insulation material, labor, accessibility, and whether existing insulation requires removal.

Yes, energy-efficient homes are increasingly desirable in the market.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
