Exterior cleaning and general contracting services for homeowners and businesses in Mountlake Terrace and the greater Seattle area. Every job starts with a free estimate.
Window cleaning covers the glass, frames, tracks, sills, and screens — inside and out, not just what’s visible from the street. Built-up dirt and mineral deposits in the tracks trap moisture, which over time can cause sticking, swelling, or staining if it’s never cleared out. We hand-wash and squeegee the glass to a streak-free finish and clean out the tracks and sills so the windows keep opening and closing the way they should.
We hand-clear leaves, seeds, and debris from inside the gutter channel, check that downspouts are flowing freely, and wash down the exterior fascia and gutter face. Clogged gutters force water to back up and spill over the edge instead of draining where it’s supposed to, which can saturate fascia boards, stain siding, and eventually reach the foundation. Clearing them regularly keeps water moving through the system and reduces the risk of that kind of water damage.
We wash the full roof surface with low-pressure equipment rather than a standard pressure washer, lifting dirt, algae streaking, and organic staining that build up on shingles over time. High-pressure washing can strip the protective granule coating off asphalt shingles, shortening the roof’s lifespan and potentially voiding the manufacturer’s warranty. The low-pressure method removes staining and growth without stripping that coating, so the roof looks clean and the shingles stay protected.
We apply a zinc sulfate treatment across the roof to kill existing moss and keep new growth from taking hold for up to three years. Moss holds moisture against the shingles, which can cause them to lift, curl, or rot, and over time it can work its way under the shingles and into the roof deck. Treating it early is far less costly than repairing the damage established moss can cause, and it’s typically paired with a full roof cleaning to start from a clean surface.
We pressure wash driveways, walkways, patios, and other concrete surfaces to remove dirt, mildew, oil stains, and general grime that builds up over time. Concrete can handle higher pressure than roofing or siding, so we can work into the surface texture and lift stains that have set in for months or years. Left untreated, mildew and algae growth can make concrete slick, especially in shaded or damp areas — cleaning it restores an even appearance and a safer walking surface.
We wash wood fences with low-pressure equipment to remove dirt, mildew, and the gray, weathered look that builds up on untreated or stained wood over time. Washing wood at the wrong pressure can splinter the surface, strip existing stain, or drive water into the grain, so we use a lower setting and technique suited to wood rather than concrete. That keeps the fence clean without the damage, helping it hold up longer before it needs to be restained or replaced.
We wash the full exterior of the home rather than just the sides visible from the street or driveway. Mildew, algae, and dirt build up fastest in shaded, damp spots — under eaves, around downspouts, and on north-facing walls — and left alone, that buildup can gradually break down the siding’s finish and trap moisture against the material underneath. A full wash clears that buildup and gives us a chance to flag anything else we notice along the way, like a loose panel or an area that could use recaulking.
Beyond exterior cleaning, we also handle general contractor work like deck repair, drywall, and more. Reach out to discuss what you need.
