"Price was about average, can't complain - don't remember exactly how much or exact service date (disclaimer).  Company screwed up the scheduling.  Installer was busy with personal life and we had to work around their schedule.  Inconvenient.  Came out and sprayed insulation in the garage.  They left the door open to the basement so the entire chemical smell inundated the basement.  The spray was general even but there seemed to be small holes and spaces generally through out the insulation.  When I inquired about the small spaces the response was they generally use the small spray cans you can get at Home Depot\Lowes but that they didn't have any.  I said I would take care of it myself, I had enough inconvenience with the screw up in scheduling.  Other than that went well - it's not that involved, just spray foam. 
They did clean up the mess relatively well, but not perfect."

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

"They did a wonderful job. They spent part of 2 days to cover approximately 1500 square feet of vapor barrier in a very difficult low clearance areas to access. They were professional, highly skilled and I would highly recommend this company to service any crawl space/ foundation issue. I have already referred their service to friends and plan to have the crawl space medic continue to inspect under my house. I learned your crawlspace is very valuable to your air quality and the value of your home and so often overlooked. They use higher quality 10 mil versus typically 6 mil vapor barriers at a much better price.

Insulation FAQs, answered by experts

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.
