"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 I originally made the request in August and this morning on Nov 10, I got a phone call inquiring if we still needed insulation done.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."

"We recently had the pleasure of working with JC Construction for drywall repair and interior painting throughout our home, and we couldn’t be more thrilled with the results! From start to finish, the team was professional, courteous, and highly skilled. Juan offered expert advice on the best way to handle the drywall repairs. The finish was exceptional and no dusty mess. We also had them paint the entire interior and every room looks fresh, vibrant, and beautifully transformed including a gorgeous paneled accent wall in our bedroom. The precision and attention to detail was particularly impressive and the clean-up after the job was done left our home looking spotless. Juan communicated clearly throughout the entire process. There is a true commitment to customer satisfaction that you rarely find in a construction company, especially at such an affordable price. We used them for drywall and painting services, but we highly recommend JC Construction for any home construction project. They exceeded our expectations in every way!"

"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."

"Israel was extremely professional, communicated well and the job he did was top-notch. He repaired a poorly done ceiling drywall that was initially damaged due to water leaks. He completed the job in 2 days as he promised and his rates were very reasonable. I would highly recommend him for all drywall needs."

"I went with this company to do a Drywall installation and painting on my Tuff shed. I could not be more delighted working with this company and their employees. Polite, hard-working, prompt, efficient and professional-- just a pleasure to work with a top-rate company after having so many poor experiences with other groups. Cannot recommend them highly enough."

"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."

Drywall Insulation questions, answered by experts

The person’s skill will affect how many drywall sheets they can hang in one day. Some people can hang 10 or more sheets in a day, while others may only hang six or seven sheets. It also depends on the framing complexity since custom cutting and fitting the drywall can prolong the process.

Whether you can reuse a drywall anchor depends on its type, material, and how it is removed. Plastic anchors, such as expansion or self-drilling types, are generally considered single-use because they are designed to expand and are likely to break or become deformed upon removal. Metal anchors, like toggle bolts, are more durable and can often be reused if they are not damaged during extraction. However, with toggle bolts, the toggle mechanism can fall inside the wall when the bolt is removed, making it difficult to retrieve. If an anchor is damaged or must be cut for removal, it cannot be reused regardless of its material.

Drywall is safe to cut as long as you follow proper procedures, such as wearing personal protective equipment and using the right tools to score and cut the drywall. When cutting new drywall, it can release dust with silica and other compounds that could pose health risks. Leave cutting drywall to the pros, or wear a high-quality respiratory mask, goggles, and other PPE when handling drywall.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.
