Interior remodeling, refinished basements, ceilings, floors and drywall. Careful attention to detail leads to a great quality of work. A team you can trust to be there when they say they will, offering fair prices with astonishing quality.

"I reached out to Supreme Interiors and received a call within an hour and a in home consultation within 48 hours. While explaining what I was looking for, Justin offered suggestions on how to make it better. He provided a fair price and scheduled me quickly. On the day of my installation, Justin was on time and started working right away. I loved the final product but I realized that I explained something incorrectly to him so I asked to change the design after the work was complete. He was so gracious and understanding which was very kind considering the circumstances. I HIGHLY recommend Supreme Interiors. Justin and his team are very professional and provide great service. I’ve already hired him for another job."

Drywall Insulation questions, answered by experts

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.
