"After getting quotes from a few companies, we chose ThermaCore Insulation for our attic insulation replacement and are very happy we did. The crew was hardworking, professional, and paid attention to the details. They removed the old insulation, cleaned everything up, and installed the new insulation efficiently. The house feels more comfortable, especially during the afternoon heat. The entire process was smooth and stress-free. Highly recommend ThermaCore Insulation to anyone looking to improve their home’s comfort and energy efficiency."

"Fantastic. Always on time and very friendly. I love knowing my attic is clean, sealed and insulated. I have actually stopped sneezing!!"
You will never look at your home the same when you see what "Stack and Draft” is doing to waste energy.
Window Replacement
When you heat your home the hot air rises and begins to “Stack” pressure on the ceiling until it finds an escape route around the many holes hidden in the construction where walls and light fixtures meet the ceiling. The hot air leaking creates a draft by pulling in cold air from outside.
Window Replacement
The more you turn up your thermostat, the more "Stack" is applied to the ceiling, accelerating the icy cold "Draft" right behind it.

"Old shake roof was removed, new insulation added, plywood base with roof paper cover. Then tiled over raised battens. New gutters and downspouts. Dry rot repairs and painting of new surfaces.The whole process took four days. The bid and contract were presented very thoroughly, each item of work detailed and priced. Many choices. The work crews were very pleasant. The work was done in a set order and a company rep would call to inform of the next step and when it would happen. At the conclusion of each days work the property was cleaned and as tidy as possible given the nature of the project. When finished, a company rep inspected the job and checked for any needed corrections. All in all, an outstanding contractor to work with."

Insulation questions, answered by experts

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.
