"I had the foam insulation put in my attic and I am very pleased. The results were better than I thought. The attic was reading around 140 degrees and now it is 92 at the hottest part of the day."

"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

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.
