"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"I have had Art come over and install a Solar Tube in our bathroom, which was awesome and not only do I recommend Art, I recommend Solar Tubes in general!!

We moved into a house recently that has 5 skylights in it, all of them were ancient and energy sieves.  I had Art price up replacing with new energy efficient skylights, with solar blinds to add extra insulation.   I'm so glad I did, as the old skylights were not only in bad shape, and energy inefficient, they had leaks, and were poorly installed.   He put down drop cloths wherever he was working, and you'd never know the guys were there after they left.  Can't ask for much more than that!!

My new Solar Tube, Velux skylights and solar blinds are awesome, and I know they were pricey, but wow...totally worth it."

Drywall Insulation questions, answered by experts

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

Brick and stucco are a lot more different. You must use picture hanging clips designed for brick walls, or use a plaster rail system with adjustable hooks. Any other type of hanging hardware will cause damage to the bricks behind. You won’t be able to really use nails, either, because they’re not strong enough to go into the bricks.

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.

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage.

Drywall anchors won’t work on plaster. Instead, they will more than likely cause more damage and pull out the plaster. The best type of anchors to use on plaster walls are the ones that will bite into the surrounding area, such as molly bolts and toggle bolts. Masonry anchors with expanders on the sides also work for lighter pictures.
