Customers say: True professional

"My husband and I chose True Building Performance because of their 5-star rating. We were very impressed with Paul’s timely responses to our calls and questions and the team’s professionalism throughout the process of insulating our attic. Paul and Joe took the time to show and explain to us exactly what the job would entail, and we trust that their work was completed in an excellent manner. It was a pleasure to interact with their team, who were punctual, respectful and considerate of our home. They demonstrated competence and congeniality when interacting with each other which we greatly appreciated. They offered a fair price for the job, and there were no surprises with additional costs. We gladly concur with the 5-star rating!"

"What an absolute DREAM! Correct Energy is an incredible company. Knowledge, professional and efficient! I contacted a few insulation companies but the proposed methods were not through. Correct Energy and especially Ray’s knowledge and experience were above and beyond. CE came out to assess and spent a generous amt of time explaining EVERYTHING. CE came when they said they would. The crew was professional and spent a few days here. They left everything immaculate. My place is old, built in the 1940’s so many challenges came up that they handled like absolute pro’s. Their work has and will continue to save so much on energy, the difference of before and after is immediate and drastic. I can’t wait for them to come back and do my basement next! I can't say enough about this company. Pros work here!!! Hire them!!! You will not be disappointed.."

"Asked for a quote on removing an old deck, replacing with a larger one. Price quoted was fair, and we accepted. We're very pleased with the final product, and the whole ordeal was hassle-free for me and my wife. Every worker involved was very professional. Communication from start to finish was excellent, and I feel the job was completed faster than we had expected. Will be using this company in the future for other projects."

"Overall, excellent. We did encounter a few problems with the spray in wall insulation since the original sheet rock was just nailed in. A few sections bowed into the room. This is actually pretty common with old houses. The problem was quickly corrected, the walls properly secured, the insulation reinstalled (blown in) and the job completed. In modifications to a home, it is not always the problems you encounter, it is how you deal with them. Advance had the problem identified with a resolution that was completed within a day. Very pro-active!"

"From the moment we met nick we felt comfortable. After my gf got taken for money from a contractor we were a little hesitant on trusting anyone again.. Nick gave us a quote for the job that we were very happy with. And insured us we would be very happy. And wow were we, nicks crew was amazing , friendly and cleaned up everything when do e. Can't say enough about nick and his team. This is how a business is supposed to be run. Don't even bother calling anyone else. They did an amazing job on our building and more importantly? Welcomed us like we were family during the process... 100 thumbs up. Chris and Christina"

Insulation FAQs, answered by experts

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.
