Cobblestone is not a type of rock but a term for a mosaic or rock laid down as a surface. It used to be made from the closest available stone but now can be made from nearly any hard rock, as machining has made shaping the stone much easier and cheaper.

Cutting stone comes with a number of safety hazards. First and foremost, if you’re not comfortable with the equipment required to cut stone, including blades and grinders, you could easily injure yourself. The heavy machinery also poses a risk to your ears if you don’t wear proper ear protection; similarly, you need to wear eye protection to keep debris from irritating your eyes.

However, the biggest risk from cutting stone comes from the stone dust. When breathed in, stone dust can be a huge hazard to your lungs. Always wear a face mask when cutting stone to prevent inhaling stone dust, and thoroughly clean the work area when you are finished.

To avoid injury, we recommend hiring a stone-cutting professional, rather than attempting this job yourself.

While painting can certainly change the look of a chimney, you should think twice about giving your brick chimney the old landlord special.

Painting brick is porous, meaning it’s full of tiny holes that can soak up moisture. Those holes also allow it to dry, though. So, when you paint it, you trap any moisture inside, providing an opportunity for mold, mildew, and water damage.

Paint also shows wear faster than naked brick. This means that once you paint a brick surface, you’ll have to keep painting it to maintain a clean look. A paint job is also harder to undo on brick because of its porous nature. Once you paint it, it’s hard to go back without some serious power washing—another added cost.

Solid brick structures can last a century or more, potentially 100 to 150 years with proper maintenance like tuckpointing. Without major repairs, classic red bricks may last 20 to 40 years. Brick veneer siding is also a long-lasting material, with a lifespan ranging from 50 to 100 years, provided it is properly installed and maintained. To maintain brick veneer, you should scrub it annually with a special detergent and a soft-bristled broom. It's also important to inspect the bricks and mortar regularly and hire a masonry contractor for any necessary repairs, such as fixing worn mortar or bowing bricks.
