Brick Characteristics:

For a long time, clay brick has been one of the “must-have” materials in construction, used for building walls and paving surfaces for driveways, roads, and patios. Brick is the most popular choice for a home’s exterior according to research by the National Association of Home Builders. There are up 34% of the correspondents who are willing to pay more to get a brick siding while 21% would go for vinyl siding and less than 15% of them like stone and stucco.

Repointing is necessary to replace the old mortar and secure the stability of the structure. Brick is also a common material chosen to build pavers and arguably the most elegant among the paving surfaces and beefs up the value and beauty of your home
