Customers say: True professional

"just now True building Performance's crew did an incredible job for us. The project was to insulate our home. These guys showed up with cheerful attitudes and completed such an incredible and efficient job. From start to finish they were friendly and interacted with our family all while working in the project. The kids enjoyed watching them work. They cleaned up after themselves too which was a pleasant surprise . It was also great that we were able to get more done than we had anticipated. Originally we had elected to insulate upstairs only but we are able to completely insulate the entire house, downstairs being from the inside. They have plastic protecting their workspace from top to bottom. Joe, the lead contractor is so knowledgeable and incredibly acomodating. Paul Mendel the company's owner is the same way. A great company to do buissness with. We are just overwhelmed with gratitude and amazement at what a difference we are already noticing in the reduction of street noise from the cellulose insulation. I would Highly recommend True Building performance to anyone looking to seal air gaps and install insulation."

"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!!"

"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!"

Insulation questions, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.
