"My professional window installers were prompt, courteous, friendly and most importantly knowledgeable. They were able to answer my concerns and questions before during and after installation. The rooms were left clean and orderly. The yard and carport where the windows were stored after delivery by Lowe's was spotless, the old windows, trash and debris were gone! Very impressed! When we signed the paperwork for an installer we didn't know we were getting an entire company with Severson, Inc. Thank You Denise Capps"

Plaster Repair FAQs, answered by experts

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even 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.

Like many other repair projects, the cost to fix a behind-the-wall shower leak depends on several factors. The cost of your repair may depend on the type of leak (from a clog or burst pipe), type of piping, and location of the leak. The extent of the issue and how difficult it is to access the pipes can greatly impact and increase your price. On average, you can expect to pay around $150 to $600 to repair a leaking shower.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.

It depends on the construction of your wall. Most handypeople can fix small holes in drywall. If your wall is plaster or brick, more significant damage may require a drywall contractor or a mason. Hiring a handyperson costs less than a more specialized type of contractor, but they’re not trained in all types of wall repairs.
