"

Insulating the exterior walls of our two story, 1700 sq ft house, involved drilling holes between each stud, blowing in insulating material, plugging the holes, spackling over the holes, priming and finally painting the holes.  Two man crew was very efficient in setting up scaffolding and then doing the work described.  We got a chance to see what the insulation looks like inside the wall when the force of the insulation popped out a built-in bookcase that was not secured.  Its a solid blanket of insulation, filling in the entire space.   Very impressive.  The results have been very noticeable.  The house feels more comfortable, and the heater turns on less frequently.  We should have done this years ago. 

Last part of the project was to blow additional insulation into the attic, which went very quickly.  Overall, the project took 2 very long afternoons/evenings to complete.  It makes a mess around the outside of the house, but they did a good job of cleaning up each day.

"Had a great experience hiring Bay Valley Insulation. The quote arrived very efficiently and was the price I was looking for. The crew of Tony and Henry arrived inside the scheduled window and work was completed in a timely manner that day. The job looked great in the blown attic and final clean-up was great. Thank you."

Drywall Insulation questions, answered by experts

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.

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.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

Walls should be as smooth as possible before applying peel-and-stick wallpaper. Although you technically can apply wallpaper on textured walls, the peel-and-stick variety won’t last long without a clean, smooth surface for the adhesive to stick to. If you have textured walls, consult a pro about removing the textured finish before moving forward with wallpaper.

Plaster is a beautiful finish but is labor-intensive to install and remove. It’s vulnerable to cracking and more sensitive to moisture variance than drywall. Installing plaster on a new wall is an expensive process that can take days to weeks, depending on the scope. Removing a plaster wall can also be quite expensive and time-consuming.
