"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

"We are finishing our basement. We put up framing, insulation and paneling only to discover we had a condensation problem. We contacted a locally well known water damage and restoration company. After waiting two weeks, they called to tell us they were not interested in working with us. During these few weeks, we tore down the paneling and insulation.  We contacted Superior Insulation after noticing their great reviews here on Angie's List. We talked to Rick who gave us an idea of what the solution was and set up an appointment to view the problem area. Once he saw the problem area, he decided on a slightly different solution. Contract signed 3/18/15. Work completed  by Rick and Jim 3/30/15. They were very professional, thorough and nice to deal with. We are very happy with what they did.

Drywall Insulation questions, answered by experts

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.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

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.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.
