"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"I am an energy auditor and general contractor. I specialize in building science, energy efficiency and performance-based contracting. I recently needed an insulator to finish a project when my regular insulator could not.... I was in a pinch on schedule. American Insulation contacted me and within minutes I had my problem solved. We agreed on price and within 48 hours my project was complete. During the installtion process I found the owner and his crew courteous and professional. Thank you American Insulation, you have earned my business."

"I highly commend this company. Unfortunately I could not have them do the job. He came out, on time, to give me estimate on insulation. He was very honest with me! To do this Job would have required me to have additional projectsâ replace aluminum siding, and holes would be in paneling which was wallpapered over. I am recently widowed and will probably be downsizing in few years. Rather than spending money and doing other projects, decided not to do it. Most companies would have said â oh yes, we can do thisâ and them made a mess! Itâ s nice to know there are still decent, honest companies around."

"Zach stopped by shortly after I called to measure and gave me an estimate quickly. I acquired several other estimates and Zachs price was competitive (about in the middle).  I informed Zach that I was interested in his services and the date I wanted to start. Zach and his crew (Him 2 other roofers and a laborer) actually got started a little early and it happened to be on one of the days it was close to 100 degrees. Even in that heat they worked promptly and professionally so I bought them a case of water and had it on ice for them to drink plus my daughter offered freeze pops occasionally and they greatly appreciated it. Once they removed the top half of the shingles and sheathing they laid tow boards for the Mold company to be able to remove all the old insulation and do their work. At night because my house was fully vulnerable to the elements of nature (rain) Zach covered my house with a brand new Tarp big enough to cover everything to ensure no water if it did rain would enter and do damage. Zach and his crew had to wait until all the mold remediation process was done and then removed the rest of the shingles and sheathing. Then they installed all new sheathing (3/4 OSB), shingles(Owens Corning Duration Dimensional Shingles) gutters, downspouts, drip edge, and new aluminum covered fascia boards and covered Gable trim with aluminum then at  the end installed new Ridge Vent (Owens Corning Vent Sure Ridge Vent). When the job was completed they cleaned up very nicely.
I was very impressed how Zach and his crew was able to work with the other contractors, work in extreme temperatures, and clean up very nicely. I would definitely recommend "Always Perfect Contracting" and actually will have Zach coming back to my house for another job very soon."

"Overall, the team at Exceptional Exteriors were wonderful to work with, and I'm happy with the result.  A few specific things that I appreciated:
- Roman was able to come out and give me an estimate the same day that I contacted him.
- He worked with my budget and expectations, giving me options that would keep my costs where I needed them to be.
- The work on my roof was scheduled quickly (as it was the off-season), but was delayed because of weather on several occasions.  The office team at Exceptional Exteriors kept me updated regularly and were never difficult to reach by phone.
- They provide options for financing and connect you directly with lenders who will be able to best serve you.  (I was connected with a 12 month 0% interest line of credit at Dollar Bank, which was a very simple process.)  If you use their lenders, they are also very accommodating about the timing of the payment and doing the work.  (They had an opening to schedule the work before the financing was complete, but were able to confirm my eligibility for the line of credit and went ahead with the work.)
My ONLY complaint was a small oversight on the part of the office team at Exceptional Exteriors.  While they did such a great job keeping me updated when the work was delayed, the actual day that the workers did arrive, I had no advance notice.  I woke up to see a gentleman on a ladder right outside my bedroom window.  I have a sense of humor and it made for a funny story at work that day, but I would have preferred the opportunity to ensure my curtains were closed.

"We were very pleased with the overall experience—the issue was assessed quickly and accurately and the plumber, Jake, was friendly, professional, and happy to explain things along the way as well as answer any questions. The only drawback was cost (to be expected, I suppose) and the fact that they don’t do drywall repair following the job (which we were told ahead of time but is still a little disappointing)."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Drywall Insulation FAQs, answered by experts

Yes, it is possible to rewire a house without removing the drywall, but this doesn’t work in all homes. You can pull out old wires and insert new ones if you have access to the wiring system via the ceiling or through a crawl space. Some pros can also use a magnetic kit to fish the old wire out of the wall through a hole cavity and install the new wires. Just keep in mind that doing this is less stable than removing drywall, as you won’t be able to staple the wires into the framing.

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.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

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.

You can skim coat plaster, but it’s better to repair the plaster itself. A skim coat is a thin coat of drywall joint compound spread over the surface of a wall. The result is a flat finish that looks pleasing, but part of the appeal of plaster is its imperfections and aesthetic. Skim coating is best when limited to drywall applications.
