"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."

Our primary bedroom is above the garage and even though we have a newer home, you can feel cold air coming thru the floor.  It's the coldest room in the house by far.  Ed's team came in and placed foam insulation in the garage ceiling.  He gave us $100 off for Angies list discount which was nice.  They cleaned up well when done.  Now that it's warm out I can't grade the quality of the work until winter again because I won't know till then if its helping with the problem.  I will come back and update then.  We had been quoted over $6000 by another company to do the work so hopefully this works and comes in far cheaper.

"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!"

"They were professional and on time. They cared about our house and put down tarps and stuff to walk on. They did an excellent job on the installation and were helpful in explaining how the system worked. They went over all the components that they installed. From what I can tell, they did a neat job. They had to break a window to vent to the outside. They didn't clean up the broken glass on the outside of the house, but it was probably just an oversight."

Insulation questions, answered by experts

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

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.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
