"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."

"l  spoke with three other solar installation companies and was unhappy with the level of professionalism and the knowledge of the salesperson. I had decided to cancel the idea when I came across Sunpro in an ad. I was attended to immediately, a very impressive assessment was done to analyze the amount of electricity I have been using through the years and exactly how many solar panels I would need to cover my power needs without overpaying for panels that were not needed.
Everything was documented for me in a very professionally done color booklet with all the facts, figures, and graphs that made it very easy for me to understand the entire process, costs, benefits, and etc. During this process I was advised what Government rebates were available for the installation of solar panels AND that if a structure was needed to mount the panels to, rebates might also apply to the cost of the structure. We had been considering adding a patio to our home and Sunpro showed us the benefit of building the patio now which would provide the exact location and angle for the panels to capture the maximum amount of sunlight.
The entire job was done in a surprisingly short time and the quality was superb. The patio (including stamped and colored concrete) turned out beautifully. Frankly, I don't think I have ever been truly satisfied with any work that has been done on my home until this experience. Even the city inspector remarked at the excellent quality of the work that was being done.
In addition, the Sunpro system included making the entire house energy efficient by spraying foam insulation in the attic and sealing the entire house. This extra step (which was never suggested by the other companies) has made an amazing difference in the way the home feels and it allowed for fewer panels needed to provide the power my family requires (saving me money).  I have found out since the installation that Sunpro used certain components in their system that were far superior to what the other companies had advised. These small and inexpensive upgrades have made this system far more efficient than what I had been shown by the other companies.
The owner of Sunpro provided amazing supervision for the entire job. Sunpro also provided ALL the documentation I needed to apply for the rebates and tax credits. Everything was put in an organized folder to give to my CPA. The entire process went perfectly. Since then, Sunpro has done other work for me that has also been done perfectly. I don't know if solar panels are right for everyone, but this is definitely one of the best decisions I have ever made. since the installation, I have not pain an electric bill. In fact, at this time the electric company owes me electricity.
I might add that in my particular case, the entire project costs LESS than what it would have cost me to build the patio alone.
Frankly, it is my policy to NEVER recommend anyone. I have taken the time to write this extensive recommendation only because I am 100% satisfied with the way the job was handled and the quality of the work and materials and the outcome of the entire project.

"Paul, the operations manager, came out to look over the work to be done, discuss my concerns, and gather data for a free estimate. Ann, the office manager, had a detailed estimate to me within a day or two and I agreed to have the work done. The workers showed up promptly as scheduled each day of the job. The excavation turned out to require less time than estimated, and only half of the insulation needed to be replaced. Paul adjusted the quoted price accordingly. The work was done professionally and to my satisfaction. Paul and Ann kept me up to date throughout the course of the job. I would not hesitate to call on Crawlspace Medic again should the need arise."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

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.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.
