Local Details
A lot of Covington neighborhoods were built with light-colored siding and wide concrete driveways, which is exactly where our climate shows first. Green algae settles on the shaded side of the house, driveways dull out to gray, and gutters fill with fir needles long before anyone notices water spilling over the edge.
We treat siding and trim with a soft wash so the finish and caulking stay intact, then pressure wash flatwork with a surface cleaner so the concrete comes back evenly rather than in patches. Roofs are cleaned gently, which matters on the newer asphalt shingles common in Covington developments.
Gutter cleaning is one of the most requested jobs we do here. Debris is cleared from gutters and downspouts so rainwater drains away from the roofline, siding and foundation instead of soaking into them.

Before & After
Exterior cleaning is easiest to judge with your own eyes. Here is the kind of difference a proper wash makes.



Common Questions
Yes. Soft washing uses low pressure with a cleaning solution, so it lifts algae and grime without forcing water behind the siding or damaging the surface.
Late fall after the needles and leaves have dropped is ideal, with a second check in spring if your property has tall firs nearby.
Not usually. We only need access to an outdoor water spigot and the areas being cleaned, and we'll confirm the details before we arrive.
