"He actually pointed out to me that I needed more insulation over the whole home as over a period of time it packs down. So I let him do the whole home as well as garage that I had originally wanted a quote on."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"We were very pleased with the work that was done. We were in process of selling our home and needed the interior painted. We needed cracks in plaster repaired, and some drywall repaired then painted. Mr Watson was very polite , listened to what we wanted, done the work in a timely manner and done neatly. I highly recommend Watson Property Solutions."
Was a long and intense project but we managed to pull it off and get to the point that makes its all seem worth it.

Drywall Insulation questions, answered by experts

Metal corners, often referred to as corner beads for square corners, are used on drywall installations to provide structural reinforcement to vulnerable outside corners. Their usage safeguards against chipping, denting, or other forms of damage, enhancing the overall durability of the wall. Metal corners also offer a precise and straight edge that facilitates sharp and clean lines, crucial for achieving a polished and professional finish.

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.

Yes, you can speed up the time it takes for plaster to dry, but it's important to do so carefully to avoid issues like cracking or crumbling. Proper ventilation is key; open a window or use a fan to circulate air in the room. Heat can also accelerate drying, but be cautious, as too much heat can cause the plaster to dry too quickly and crack. Check the plaster's packaging for the recommended drying temperature and set the room's thermostat accordingly. While managing humidity is important, avoid using a dehumidifier, which can remove moisture too aggressively and result in crumbly plaster.

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.

Costs depend on damage extent of damage, labor, finishing, and whether mold remediation is needed.
