"I hired KJ Drywall to frame, insulate, and sheetrock/texture a basement bedroom. Kevin did a great job. He was very knowledgeable about what needed to be done. He worked very hard and completed the job in a good time. He seems pretty efficient. We had a plumbing issue during his work, and he had someone out to fix it within about 45 minutes. The repair was made in Avery professional manner. Long story short, this fellow and his help were very good to work with, very fair with the price, And Kevin seems like just a really good guy. Glad to have worked with him."

Masonry FAQs, answered by experts

You will repoint over a fraction of the old mortar, but you should scrape away 1/2 to 1 inch of mortar from the joints before repointing. Otherwise, the repointing is only masking the weakened mortar instead of actually replacing it, which could put your chimney at risk of bigger, more expensive damages later on.

Always work with licensed and certified masons in your area when installing a stone wall or even a stone veneer. Just like all home designers, they should provide an impressive portfolio and offer a free estimate for the project. Pick the pro who fits your budget and schedule and, most importantly, helps you realize your landscape vision.

Painted exterior brick does not usually need sealing. Brick is a porous material, so you don’t want to apply a sealant that could trap moisture inside the bricks and cause erosion and structural damage. The risk of moisture-induced damage after sealing is higher in colder climates where trapped moisture can expand if it freezes. On the other hand, it makes sense to seal really old brick or kitchen backsplashes, where moisture from cooking can weaken the brick.

You should use cement for a chimney crown. The purpose of the chimney crown is to protect the mortar below from water damage and the effects of weather. For this reason, chimney crowns should only be made using cement. When repairing a crown, use caulks and sealants designed for cement repair rather than mortar repair.

Brick and stone are durable, low-maintenance materials for siding and walls that offer excellent insulation, aesthetic appeal, and can increase property value.
