"They did a nice job overall. They had to remove siding outside and blow in the insulation. They also did have to insulate one wall on the inside of the house as it was bricked outside. They drilled holes in the walls to blow in the insulation. They then filled the holes and have them ready for me to prime and paint. They moved the furniture when needed.

The windows did need caulking. The first window they used white caulk instead of clear. They did kinda a messy job , but then completed the job with clear caulk. It was completed nicely."

"Stendahl Exteriors was very knowledgeable about the insulation problem/getting a new roof and new siding. They were able to complete the work in a very timely manner.  We weren't planning on the insulation being done but they were very helpful and courteous in helping us fix this."

"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."

Drywall Insulation FAQs, answered by experts

How you hang the drywall can affect the finishing process. It's often easier to finish horizontal drywall panels, as the seams run across the wall rather than up and down. Standard drywall panels are 48 inches wide, so the seam is easy to reach without bending down or stretching your arms.

The best way to make long, straight cuts is to use a utility knife and a T-square to score the sheet, snap along the score, and then finish the cut by cutting through the paper on the opposite side with the utility knife. If you’re making small cuts, curved cuts, or cutouts for electrical boxes or light fixtures, you can use a manual jab saw to keep costs down, but an electric spiral saw or oscillating multi-tool will get the cleanest, fastest cuts possible.

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.

It’s always better to follow proven drywall repair tips and fix the seams that look bad. However, if you simply want to make them less noticeable until you have time to fix them, you can use paint. A darker color of paint makes bad drywall tape seams less noticeable than light-colored paint. Matte paint hides bad seams better than glossy paint does, too.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).
