"We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!"

"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.

Drywall Insulation FAQs, answered by experts

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors. 

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.

You can put drywall mud over paint to even out the surface or entirely resurface it. Sand the surface with 280-grit sandpaper, vacuum the debris and dust with a shop vac, and clean it with a slightly damp cloth. Allow the surface to dry. Apply drywall primer, especially if you’re skim-coating an entire wall. Apply the right type of drywall mud over the surface and smooth it with a trowel. Allow the layer to cure fully, then sand it before applying another layer or painting it.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

When used correctly, drywall patch kits can work well. However, there are limitations. Specifically, these kits can only cover holes up to 5 inches in diameter. For anything larger than that, you’ll need to cut out the affected section of drywall and replace it with a new piece. That’s a far more complicated process that involves buying the right type of drywall, finding the wall studs, cutting into your wall, and screwing the replacement drywall in place.
