The surface keeps its condition, right up until it doesn’t
Grime is not a neutral layer sitting on your siding. It holds moisture against the surface, and moisture held against siding, a deck board or a concrete slab is what starts the failure. Algae and mould root into what they sit on. Freeze-thaw cycles then work the moisture into the material, and the surface starts to crack, pit and shed.
That process is slow and then it is not. A deck that has gone grey and soft is a deck that needs boards replaced, and that is a different project by an order of magnitude. Siding that has been left long enough can need a repaint — which is another job entirely.
Cleaning the exterior is not about how it looks. It is about keeping water and organic growth off materials that cannot afford to stay wet.
What our pressure washing includes
- Pressure matched to the surface — enough to shift the grime, not a figure picked without looking at what we are washing
- Driveways, sidewalks, decks, walkways, fences, building exteriors and roofs
- Eco-friendly, biodegradable detergents, safe for plants and pets once dry
- A fixed price in writing before the work starts
Window cleaning is not part of a wash. It is a separate service, quoted on its own estimate.

A typical pressure wash averages around $119. Your written estimate carries the exact figure for your house.
When it needs doing
Once a year for most homes in this area, in spring after the winter grime and before summer growth sets in. Any surface sitting under trees needs it more often. If you are seeing green streaks on the north side of your house or dark spotting on a deck, that is mould and algae establishing, and the longer it stays the more of the surface it has to come off.
Curb appeal you can see from the street
In addition to maintenance benefits, pressure washing significantly improves a property’s curb appeal. A clean, well-maintained exterior can leave a positive impression on guests, potential buyers, or customers. Whether for residential or commercial properties, pressure washing restores surfaces to a like-new condition, creating a fresh and inviting look.
Mold and mildew do not clean themselves
Beyond aesthetics, pressure washing also contributes to a healthier environment. Mold, mildew, algae, and other contaminants can accumulate over time, posing potential health risks. Regular pressure washing helps prevent the buildup of these harmful substances, promoting a cleaner and safer space for occupants.
Overall, pressure washing is a valuable service that offers both practical and aesthetic benefits, making it an essential maintenance practice for property owners.
