"Tim, Taylor and Larry were absolutely wonderful. They were always on time for this 2-day job, and cleaned everything up after their work was done. They explained what they were going to do, answered all my questions, and did a thorough job. I definitely recommend Home Performance Professionals!!! Mark & Sharon P. Niagara Falls, NY"

"The price was $2,575 lower than the same work estimate from another company. The work actually took two days. They covered the tubing outside the house with a grey covering to match my siding so it would blend in the way I requested. They listened to my concerns and answered all my questions. They gave me two options on where I wanted to choose to place the outside unit. I am very happy with the quietness of the units compared to my old window a/c's. The units are very powerful and can be adjusted any way you like. Since they're wall mounted they are space savers. Plus, they can heat too. I am happy with the work done and wish I had done it years ago. The two men installing were very professional and courteous. I will be using them again for other work, such as insulation, etc."

"We hired Energsmart Insulations to insulate 2 sides of our house because of some rather loud neighbors. Their price was very reasonable, they even bumped our project date ahead of their schedule because of how loud they were. Once they started the project they found that all of our plywood between the siding and studs were beyond rotted. They even showed my wife and I that some of the siding was not even nailed to anything because of how bad the rot was. They could of easily just injected the insulation under the rotted plywood but they told us they do not feel comfortable doing that because it would all torn our when we reside. We decided not to do the installation because of the unforeseen rotting issues and I really appreciated their honestly. They could of just did the work, put the siding back on and we would never have known the extend of the problem. Once we get our house resided I would definitely go with this company to insulation our home."

"They did a whole rebuild in one day , I had 4to 7ft of blow foam On each wall and ceiling of my attic they tore it out and put a whole New roof plus ventilation in a day! I was so impressed they were kind they even patched where my roof was leaking since my apt was a week or so out. I worked with Micheal Benaquist who was absolutely phenomenal. He made me feel safe and secure and was knowledgeable on any questions I asked. From financial options to helping me understand the roofing materials. I would recommend them to anyone. They are worth the extra few bucks!!!"

Insulation FAQs, answered by experts

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.
