"We recently had insulation work done by commandos Insulation and the entire experience was excellent from start to finish. The team was professional, punctual, and very knowledgeable. They explained the process clearly, completed the job efficiently, and left everything clean afterward. Their attention to detail and customer service really stood out. I would highly recommend them to anyone looking for quality insulation work at a fair price!"

Drywall Insulation FAQs, answered by experts

The age of your home can clue you in to whether you have plaster or drywall ceilings. Homes built after the ‘70s are more likely to have drywall ceilings and walls, while older homes have plaster. You can also do the pushpin test: A pushpin will go into drywall, whereas it’s much harder to push one into a plaster wall. If you’re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have.

Most load-bearing walls are exterior, though they can also be interior.

Professionals mount TVs using specialized tools and knowledge of different wall materials, ensuring safe support.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

You can drywall an unheated garage because the material handles cold temperatures perfectly well. There are no risks or downsides to installing drywall in a garage that is not heated, and the material stands up to moisture and other elements quite well. Drywall will protect your unheated garage's electric wires and cables and add fire protection. However, for effective bonding, you should install drywall at a temperature of 55 degrees Fahrenheit or higher.
