Power washing/concrete sealing

25 Jul

Good Guy Home Improvements uses a 4,000 PSI power washer with a surface cleaner to clean driveways, sidewalks and patios. If the concrete has oil or rust spots we spot clean those areas first before we seal but we typically can’t remove all the stains. Concrete is very porous so it is easy to stain an area by setting potted plants on a spot for a season, or oil leaks and rust spots. The stain sinks deep into the concrete making complete removal next to impossible. Think of it like a piece of wood absorbing stain then to get it off you would have to sand away the wood until you get deep enough to remove it, well with concrete you could use an acid but it will remove fine layers of your concrete with it and if you don’t get all the acid off your sealant won’t stick to the driveway, so we use environmentally friendly chemicals to draw up and remove the stain as much as possible.

If you live in an area where temperatures drop below freezing in the winter you will want to seal all your concrete. If the concrete isn’t sealed, rainfall will absorb into it in the winter then freeze and pop out pits in the surface of your concrete. The sealer is good for 3 to 5 years depending on where you live and how much traffic your driveway gets.

Good Guy Home Improvements has used everybody’s sealer and have found one to be superior to the rest but we aren’t giving that info away in this blog. ¬†We charge 50 cents a square foot to power wash and 40 cents a square foot to seal. The larger the job the cheaper the cost.
