"Triangle Radiant Barrier did a great job installing radiant barrier in our unfinished storage and attic. I was pleased with the whole process from the beginning where all the options for treatment were clearly explained, to the professionalism of crew who did the install, and to the final inspection. The insulated zipper door for the attic stairs is great so I don't have insulation falling down every time I touch the pull-down ladder."

"Silas Drywall was very professional and worked very well under not so great conditions. Many changes had to be made on the fly thanks to the county inspector, but Silas rose to the occasion every time."

Drywall Insulation questions, answered by experts

You can usually tell if you have plaster or drywall by touch (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, plaster does not). If you still cannot tell, peek under an outlet cover and check the cut edges. The rough edges show the composition of the wall. You will see either drywall (two paper sheets sandwiching gypsum material) or only plaster material (no paper sheets).

You’ll get better results if you soundproof the whole wall. A hole through which light can pass can also let sound waves in. Acoustical or silicone sealant applied to holes and cracks can block enough sound to make a difference. However, the more layers absorb vibrations and slow or stop sound waves, the less noise you’ll have. 

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

There are six levels of drywall finish, from 0 to 5, that refer to the amount of work performed during the finishing process.

Level 0: Drywall is hung with no finishing work.

Level 1: Tape is placed over the seams between drywall sheets.

Level 2: A thin layer of mud is applied over the tape and screw holes. This level is common for utility rooms or walls that will be covered.

Level 3: A full coat of mud covers the screw holes and tape, but the surface is not sanded. This is often used in garages.

Level 4: This is the most common finish for visible interior walls. It involves applying two coats of mud over seams and screw holes, with sanding between each coat, creating a smooth surface ready for flat paint.

Level 5: This is a high-end finish for luxury homes. It includes full taping, mudding, and sanding, plus a final skim coat over the entire surface before painting.

Depending on the place where the cutting error occurred, you may be able to fix it. Learning how to patch a hole in drywall is challenging, but if you can tape and mud drywall, you can do it. Having said that, patching is time consuming. Early in the installation process, you may find that it’s easier and far less time consuming to just start over with a new sheet of drywall, cutting a new hole in the right spot. You may be able to use part of the incorrectly cut piece elsewhere, so it’s not completely wasted.
