"We have a 30 year old home that had only 6" of Cellulose insulation in the attic. Now it has the recommended 10" @R-38. Half of home has a flat roof with about 12" of clearance for insulation that was extremly difficult to access. Thanks to the two Steves and John they "Got her done". Also got the $600 rebate savings from SRP. We are Looking forward to lower electricity bills this summer. They were on time at 6:00 am and all cleaned-up and on their way to the next job by 8:00am. Great young men, Thanks!"

"Miguel & his team were super easy to work with. He kept me informed all along the process. Blew/swept out all the debris from inside the garage after completing the job. Actually went above and beyond the scope of the project as per there were alot of items I was unaware of from previous tenants that were left in the attic. Miguel took them all out & offered to dispose of them."

Drywall Insulation questions, answered by experts

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 practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’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.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Only use spackle on plaster walls when the imperfection is small. It’s best used for nail holes or small dings in the plaster. Spackle dries quickly, allowing you to continue the repair process shortly after using it. Plaster can be tricky to repair, though, so if you run into issues, call a pro so that you don’t risk further damage.

Regularly in areas prone to moisture or high traffic to catch issues early.

While you can put new drywall over old drywall, it’s not always the best option. In some cases, drywalling over drywall can make it harder to find wires and pipes behind your walls and conceal more serious problems with your walls. It can also make the room smaller. On the plus side, putting drywall over drywall can improve soundproofing and insulation. Plus, it’s often less expensive than tearing down and adding new drywall.

You should do a little bit of sanding between adding coats of mud. Knock down any ridges or significantly imperfect areas through sanding, which should help you apply the next coat of mud smoothly. If your first coat of mud is pretty smooth after it dries, a quick sanding is all you’ll need. Don’t forget to wipe away any dust after each sanding process.
