"Petey was super quick to respond to my post. He came out to do the estimate quickly and got the job done a few days later as requested. His price was super fair and he and his partner were absolutely fantastic and the job was done perfectly. I will definitely be calling on them again when it comes time to do all the plaster in the house."

Drywall Insulation questions, answered by experts

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

Yes, any parts of drywall that are wet or overly moist will need to be replaced. Drywall is intended to be dry (it’s in the name, after all.), as excess moisture can lead to mold and mildew and eventually corrode your home’s foundational building pieces. Do regular inspections in your home to make sure all your plumbing is intact and in good condition—this will go a long way toward preventing leaks.

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.

Yes, you can mount a TV on plaster walls—as long as you attach it to the studs. Alternatively, you can use toggle bolts, molly bolts, or another type of hardware that’s strong enough to support a TV. 

If you aren’t comfortable with this type of project, you can hire a pro. The cost of mounting a TV to a plaster wall ranges from $25 to $600 (or more), depending on the TV’s weight, size, and other factors.

Textured walls can increase the value of your home if the style is modern and seen as a desirable feature and not something a prospective buyer would need to remedy. A good example of this is popcorn texture versus Venetian plaster. The plaster wall would add value to your home, whereas the popcorn texture may be something a new buyer would want to remove.
