Stone can last anywhere from 15 to 100 years before it needs to be restored. You should clean your stone flooring or countertops regularly using cleaners designed for stone surfaces. Stay on top of vacuuming to prevent scratches from deteriorating stone faster, deep clean your stone surfaces using a pH-neutral cleaning solution at least once a year, and reseal the stone every one to five years, depending on foot traffic or usage.

Rock salt and ice melts contain sodium chloride, aka salt, and are corrosive to metal and concrete. If used frequently over time, it can cause corrosion, discoloration, chipping, and cracking to patios, walkways, and driveways. You can try a rock salt alternative or hire a professional snow removal company instead. 

Chimney mortar typically lasts 20 to 30 years, depending on its quality, local weather conditions, and maintenance. Over time, exposure to moisture, freezing, and thawing cycles can cause mortar to deteriorate, leading to cracks and gaps. Regular inspections and timely repairs, such as repointing or tuckpointing, can extend the lifespan of chimney mortar by ensuring the structure's integrity.

Yes, you can technically use a pressure washer to remove paint from brick, but it comes with a significant risk of damaging the brick surface. A high-power pressure washer can be fast but may leave the brick looking unsightly. The recommended method is to first apply a chemical paint stripper, following the product's instructions, and then use a stiff metal bristle brush or a pressure washer on a low-pressure setting to remove the loosened paint. Due to the risk of damage, it is often best to hire a professional who can use low-stress methods.
