We do free estimates and take no money down until the job is started or complete, depending on size of job.

"In the past, we had Massey Tuckpointing repair and tuckpoint the brickwork on our rental property. They were polite, arrived on time, matched the mortar and brickwork, cleaned up everything and did a fantastic job without any headaches. Recently, we had them clean and inspect our chimney and fireplace at our home. Once again, their service technician arrived early. He was very polite, cleaned and vacuumed the fireplace and did a really nice job cleaning up afterwards. It was like they were never here. We highly recommend Massey Tuckpointing for all your needs. With outstanding service, A+ work and great pricing. Massey Tuckpointing is the only choice! Jim and Karen C. "

"The job was promised by the very attentive owner Doug Kropp in 1-2 weeks. He had a crew leader Paul who kept everyone on track and on time. Even though labor day holiday fell in the 2 week period, he had a worker here. All the work was custom and looks as if it was part of the existing now 19 year old home. I highly recommend this team of excellent professionals."

Home Building questions, answered by experts

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

Building permits serve a few purposes, the most important of which is to keep you and the people around you safe by ensuring your contractor does work safely and to code. Permits also help your municipality tax your property appropriately, as taxes are based on land improvements and the upgrades you make to your home. Finally, permits ensure your project won’t have a negative impact on the environment or your neighbors.

The maximum size of a tiny home you can move depends on your state transportation guidelines, but the rule of thumb is a maximum of 400 square feet. However, as long as it falls within the local limits for traveling on public roadways, you should be good to hit the road.

While a log cabin is often less expensive to build than a typical home, cabins actually have a similar cost per square foot. The main difference affecting price is that log cabins tend to be much smaller than traditional homes. For instance, many cabins are about 500 square feet, versus a traditional house which averages between 2,000 and 3,000 square feet.

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.
