Q: Do you need a vapor barrier when drywalling a garage?

• <div><p>If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.</p></div>

Q: Can I use drywall primer on plasters?

• <div><p>Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.</p></div>

Q: Do you put mesh on before or after drywall mud?

• <div><p>Whether you apply the drywall mesh before or after drywall mud depends on the type of patch it is. For self-adhesive patches, you&rsquo;ll put the patch down first and then coat it with mud. Mesh patches that are not self-adhesive will require you to put mud down first and then press the mesh into it, followed by additional coats of mud.</p></div>

Q: How do I know if I have plaster walls?

• <div><p>If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some <a href="https://www.angi.com/articles/how-to-tell-drywall-vs-plaster.htm">practical ways to tell if you have plaster walls</a>, including the following: If you knock on the wall and it feels solid, not hollow, if you can&rsquo;t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.</p><p>If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.</p></div>

Q: How do I know if my ceiling is plaster or drywall?

• <div><p>The age of your home can clue you in to whether you have <a href="https://www.angi.com/articles/how-to-tell-drywall-vs-plaster.htm">plaster or drywall ceilings</a>. Homes built after the &lsquo;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&rsquo;s much harder to push one into a plaster wall. If you&rsquo;re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have. </p></div>

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"The windows our great! Energy saving due to the insulated glass saves money and never fogs or has condensation on the windows. The durability and ease of cleaning and opening these windows are a dream! Along with the aesthetics.
The crew that came to install the windows did awesome work fast cleaned up there work area things were in great shape when leaving. Since then I have had follow up calls and follow visits to make sure everything is working as I believe it should be which it is. Great company!! Would have them do any work for me and my family and would have them do anyone else's work too. Do not let this company slip by without a try!"
