Get matched with top pressure washers in Mohall, ND

If you don’t use the right PSI setting for your fence’s material, then yes, pressure washing can ruin your fence. Specifically, if you use a PSI that's too powerful, you may permanently damage a fence. Pressure washers can also remove paint from fences, though this can be a great thing if you’re looking to restore an old wood fence.

It is best to power wash your deck and sand it, as cleaning removes grime, mildew, and dirt, while sanding refreshes the wood and allows the stain to penetrate. You should clean your deck first, sand it, and then stain it. You should clean your deck annually, while sanding and staining only needs to be done every three years.

If pressure washers are stored in freezing conditions and aren’t pretreated for such temps, any liquid remaining in the water pump may freeze, expand, and severely damage your machine. While often recommended, emptying the machine with compressed air is a long and tedious process and still may not completely drain the liquid in this pressure washer part. But adding a bit of antifreeze instead will keep it in tip-top shape without the extra effort.

You should wait until your pavers have completely dried and cured before pressure washing them. Wait at least three to five days, though some sealants may need up to an entire week. Rushing that timeline can mess with the finish, weaken the seal, or leave streaks that are tough to fix. Once the sealant has fully set, stick to a gentle approach. Keep the pressure under 1,500 PSI and hold the nozzle at least two feet from the surface. Anything stronger or closer can blast the joint sand loose or wear down the sealant you just applied.
