"John, the guy that came out to do the estimate did a very thorough job inspecting the attic. He mentioned the whole house fan (and where to buy a cover for the winter) and that they would put baffles around it and the soffets (to keep the insulationwhere it should be), and they would fix the broken screen to the fresh air vent. The guys that came out were very nice and worked quickly, but weren't rushed. I had another vendor come out that didn't even mention the whole house fan, or soffets, or the screen, and wanted more money for less insulation. I asked him, "So you just put the insulation in and that's it?" and he said, "Yes." So I knew right then he thought I didn't do my homework about the fan, and he was out for a quick buck. He did go on about his 5 star rating on another site though, and why he was only 4.8 here. And I politely listened. I really value people that aren't just in to make a quick buck. People that "understand the assignment" as the kids say. John came out to inspect and provide a plan for properly insulating my attic, and that's what the guys did. I recommend them whole-heartedly! Thank You John! Thank you R-Pro!"

"We originally had Home Genius do our roof last year, so when it was time to do our siding a few months ago we called them again because of their exceptional service and professionalism. And now we just had some windows replaced and will be calling them for any future needs."

"This by far the best and most professional company we have ever dealt with. We had another company try to trap them and they failed miserably. These guys came out climbed through our attic, took a picture of our house guest and set a trap. Caught him the next day, set another trap and caught his friend. A few days later they came our , cleaned up the mess in the attic and were gone. Not a spot of insulation in the house, not a thing out of place. Great company! You won't find anyone better."

"I highly recommend Jason and Craig there at Mold Blasters. They did and absolute phenomenal job on reinforcing the wall in my crawl space that had begun to bow. They also encapsulated the crawl space which makes me feel so good and reassured that no mold will now form. I cannot say enough about this company. Jason is very honest and follows thru with what he says. You don't get that often these days. I would give more than 5 stars if I could. Good honest work. Thanks again Jason and Craigð  ¥"

"I had a wonderful stuff with U.S Insulation. They were professional, we had an area that quite wasn't insulated right and they came out and took care of it. No questions asked and they cleaned up and they were wonderful. I would use them again in the future."

Drywall Insulation FAQs, answered by experts

Whether you apply the drywall mesh before or after drywall mud depends on the type of patch it is. For self-adhesive patches, you’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.

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.

New plaster must be fully dry and cured before painting. The drying time for plaster ranges from 1 to 4 hours, but the curing process can take more than five days, depending on various factors, including humidity levels, temperature, the amount of plaster used, and airflow in the area. You should always apply primer before painting plaster.

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

Costs range from $500 to $5,000, depending on damage size, labor, and finishing requirements.
