How Much Does it Cost to Sandblast an Exterior Surface?
Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. Sand used to be the most commonly used material, but since the lung disease silicosis is caused by extended inhalation of the dust created by sand, other materials are now used in its place. Any small, relatively uniform particles will work, such as steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell.
Uses and caution
Sandblasting is used to remove paint from stucco and other textured structures. It is also used to rejuvenate concrete, bring back the original look of brick, pebbles or other rock designs. While the process is relatively simple, the prep work is labor intensive as your contractor will need to take care to protect your windows, roof and landscaping. Additionally, due to the dangers of inhaling dust during the process, sandblasting is carefully controlled, using an alternate air supply, protective wear, and proper ventilation. These are all things that will be taken into consideration in the cost of your quote. Continue Reading

Some cities and counties will require a permit for this type of work so you may have to spend additional monies on the permit as well as any costs associated with your contractor filing the paperwork.
Be prepared for additional costs associated with protecting your neighbors home, yard as well as formal notifications of the work. Your contractor, for an extra fee, can normally be hired to visit your neighbors and answer any questions they may have. You must give your neighbors 3-days notice that sandblasting will take place. Your neighbors should be advised to move their vehicles from their property to prevent dust and/or particles from damaging/dirtying the vehicle. You and your contractor will need to do what you can to prevent any damage to your neighbors home so that you don't incur additional costs of fixing their properties.
Damage may still occur due to unforeseen complications because of type/density of texture on your property's surface. Sections of your exterior may come off during the process so you may incur additional cost to fix this. In rare instances, windows are damaged or gutters become loose. These are always risks when sandblasting an exterior surface so consider these possible extra costs when hiring your contractor. Also remember, in extremely rare cases, your neighbors may experience property damage that you will be liable for.
