"We needed retrofit wall insulation and after checking around all the listings through AngiesList, Yelp, and others, we found that only Bay Valley and SDI does retrofit wall insulation work. We went with Bay Valley because the price was reasonable and they responded quickly and promptly (can't say this about SDI*). Joel was our estimator and he came out promptly at the time and date indicated. He was thorough and thoughtful on how he approached the job, not overselling or recommending things we didn't need. We live in an older house and he appreciated the home and looked for the most non-invasive method to take care of our un-insulated exterior walls. Bay Valley's approach is to come in from the exterior walls with the typical 2-hole process (high/low) to blow in the cellulose insulation. They sent two guys in and despite a couple snags in the job, they finished the job in one full day. Afterwards, they plugged the holes, textured and primed, and the next day came in to paint (our-supplied) paint. I was really amazed how well and seamless it all looked afterwards. They did a good job cleaning and even moved the cabinets in the garage back where they originally were. The real result? The mornings have been a little bit warmer than last week, but so far the heater has barely turned on over the past couple days. The house already feels warmed and less temperature fluctuations. We already got brand-new attic insulation last Fall, but the wall insulation really did the trick. A definite recommend to anyone who needs a good team to do insulation in their home. * dealing with SDI was a nightmare, unfortunately. With *several* calls about being in the ER, then lots of other excuses, it just didn't seem like they wanted to do the job or something. I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done. sigh."

"Had a great experience hiring Bay Valley Insulation. The quote arrived very efficiently and was the price I was looking for. The crew of Tony and Henry arrived inside the scheduled window and work was completed in a timely manner that day. The job looked great in the blown attic and final clean-up was great. Thank you."

"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."

Drywall Insulation questions, answered by experts

Whether it’s better to screw or glue drywall depends on your specific budget and project timeline. Professional drywall installers are more likely to use screws and fasteners than adhesives, but it takes longer. But if you are DIYing your drywall installation, glue is a perfectly fine choice if you’re willing to pay extra for adhesive.

You should start looking for a drywall installer by choosing a local company with positive online reviews and ratings with the Better Business Bureau (BBB). Next, confirm that the professional is properly licensed using Angi’s contractor licensing tool, and ask the installer if they are fully insured. It’s a good idea to ask for recent customer references and call them to get their honest opinion about the contractor and their work. You can also ask the installer if they guarantee their work or provide a workmanship warranty.

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

Walls should be as smooth as possible before applying peel-and-stick wallpaper. Although you technically can apply wallpaper on textured walls, the peel-and-stick variety won’t last long without a clean, smooth surface for the adhesive to stick to. If you have textured walls, consult a pro about removing the textured finish before moving forward with wallpaper.
