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!"

"The service was above any beyond what we have experienced from anyone else we have hired. From the initial contact right through to the end of the project their service was outstanding. Gary, Bill, Mike and Joe were true professionals. The proposal we received was very detailed offering several options for the work we needed done to improve the ventilation and insulation in our two attics. We received daily texts letting us know their arrival time, photos of the progress and daily status updates on what was done and what was next. They took great care in covering up our furniture and floors, putting up plastic, etc. They did a great job of cleaning up at the end of each day and their final cleanup at the end of the job was outstanding. Our property looks like they were never here. They did everything they said they were going to do and more. While they were here they found a couple additional items that needed to be corrected and promptly made the repairs. We can't say enough about the outstanding work they did. They will be our first call for any future projects."

"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."

"Matt was exceptional. He did a great job. Mice in the attic. He secured the areas outside where the mice were getting in. Then he set traps and replaced a vent in the attic. His price was very reasonable and he offers a warranty. I would highly recommend Matt from Got It!!"

Insulation questions, answered by experts

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills.
