Pressure washing in St. Louis

St. Louis mornings are damp. NOAA's Comparative Climatic Data, using the airport station's 1945 to 2018 record, puts the average morning relative humidity at 81 percent over a year, and 85 percent in August and September. By afternoon it falls to the mid-50s through most of the summer. Winter is the gray stretch: from 1965 to 1983 the station logged only 41 percent of the possible sunshine in December and 45 percent in November.

On a house, dew sits longest on the north wall, under the eaves and behind the shrubs. Those are the spots where green film and black mildew tend to start.

If you're getting a St. Louis house ready to sell or rent, the city has its own reason to look at your walls. Every property in the city sits in a Housing Conservation District. Before a vacant unit is occupied, or before an occupied house is sold without a certificate from the past 12 months, the Building Division inspects it, outside included, against the minimum exterior standards of the International Property Maintenance Code. If the certificate comes with violations, the owner has 30 days to fix them.

Questions homeowners ask

How accurate is a photo estimate?
It’s a ballpark, not a quote. A photo gives us a good read on the surface and how dirty it is, but a pro who sees the whole property will always be more precise. Use our number as the range to expect before you start calling around.
How is pressure washing priced?
Mostly by the square footage and the surface — a concrete driveway is cheaper per foot than siding or a wood deck, which need a gentler soft-wash. Heavy algae, mildew, or oil stains add to it because they take detergent and a second pass.
Will pressure washing damage my siding or deck?
It can if it’s done at full pressure on the wrong surface — that’s why good pros soft-wash siding and wood. Our ballpark factors in the gentler method for delicate surfaces.
Is this really free?
Yes. No signup, no credit card, no spam. We only make money if you choose to connect with a local pro — and that’s up to you.
What photo works best?
One shot showing the full surface you want cleaned — the whole driveway or the side of the house — gives the best read on the size and how dirty it is.
