"We were referred to AJ Pro Green by a colleague so we had them come out for a free estimate. They showed up on time and were very professional. They insulated our basement during our remodel and we couldnâ t be happier. The job was done quickly, was within our budget, and communication was fantastic. We would highly recommended!"

"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"We had a leak in our roof that for years I'd been trying to figure out from where it was coming. Water is tricky because where you're seeing it doesn't mean that's the source ("water finds a way"). Finally decided to call in an expert and Adam Vaillancourt Roofing was the first company that was listed in a Google search. The first thing I noticed was the company's consistently high customer satisfaction results (at least 4.5 stars). Customer service is very important to me when doing any work to our home, which is our biggest investment. I called and spoke with Cat Vaillancourt to set up an appointment. We met with sales rep Jose Luna, who conducted a thorough inspection and found the leak easily. His presentation about the company and how they do their work was impressive and Jose was very professional. The meeting included a video that Jose shot while on our roof in which he explained not just the issues that were found but WHY the work was needed. He patiently answered all our questions and never pressured us into agreeing to anything. It's our money, it's our decision, he said. After meeting with Jose, we didn't hesitate to sign a contract immediately to get the work done. One of the biggest factors in signing was that the folks who do the work are company employees, not contractors. Fast forward a few weeks later and Paul Camarro and his crew showed up at the house on time and ready to work. When they were done, Paul showed us photos of the completed repair work, so I knew they delivered as promised. Jose is in the process of making a follow-up appointment so that he can inspect the job and make sure that we are completely satisfied. From Cat Vaillancourt and Mary Kay Macfarlane in the office to Jose to Paul, every person we dealt with at Vaillancourt was fantastic and professional. Their emails often include the signature, "The Team at Vaillancourt Roofing" and it's obvious that they truly are a team. We will absolutely be calling Vaillancourt in a few years when our roof needs to be replaced. Highly recommend!"

"Matt is very easy to communicate with, prompt work speed and does a solid job. He recently replaced a door and window that was almost replacing the entire wall actually in two days flat. It feels at least 10 degrees warmer now he's fixed all the rot and got placed in better insulated windows. Would and will re-hire for some other projects soon."

Insulation questions, answered by experts

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

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.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

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.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.
