"

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

"This is an awesome company to do business with. They are honest, reliable, and do an outstanding job. My insulation was very old and my upstairs had become unlivable because it was so hot. I sought out 3 bids and I decided to use this company because of the outstanding experience I had in working with them. The person who took my call was very helpful, courteous and warm. They came out right away to inspect and give an estimate. They did not try to upsell and I felt very comfortable in what they said I needed. The installers arrived on time, got the job done, were super conscientious and efficient. I cannot say enough about what a great company this is. My house feels so much better. Do not hesitate to contact them if you need insulation and you will not be sorry."

"Prompt service and good work. The drilled holes in the stucco and the patch work was excellent, can't easily see the patch, if at all in some cases. The only negative is that since they finished after dark, the cleanup wasn't as good as I would have liked."

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"

Drywall Insulation questions, answered by experts

Plaster is denser, harder, and more porous than drywall, so it absorbs moisture differently. This means you’ll often need more prep work, such as thorough sanding, patching, and priming with a high-quality bonding primer. Additionally, you may need more coats of paint to achieve even coverage. While the process takes more time, it helps ensure a durable and professional-looking result.

Plaster is a beautiful finish but is labor-intensive to install and remove. It’s vulnerable to cracking and more sensitive to moisture variance than drywall. Installing plaster on a new wall is an expensive process that can take days to weeks, depending on the scope. Removing a plaster wall can also be quite expensive and time-consuming.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

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.

Ceiling-mounted curtains won’t damage the ceiling if they’re installed properly. Using the right anchors or securing the brackets into joists will ensure the curtain weight is properly supported and prevent damage. However, overtightening screws, using weak anchors, or repeatedly removing and reinstalling hardware in the same spot can cause cracking or sagging over time. In that case, you might have to call a pro for ceiling repair.
