Within 24 hours, and almost always the same day during business hours. Send a couple of sentences about the job and a photo if you have one — that is usually enough for us to quote a flat price without a site visit. For larger or multi-story properties we may ask for a quick walkthrough first so the number we give you is the number you pay.

Most Seattle homes land around $300, with a baseline near $10 per pane. Smaller single-story homes with easy ground-level access start around $149; large multi-story properties with a lot of glass or awkward access run $500 and up. A recent two-story West Seattle home came to $249, which is typical for that size. What moves the number: pane size and count, how many stories, and the windows themselves — older wood-frame sashes need careful hand-cleaning and take noticeably longer than modern metal frames. Baked-on staining such as bird droppings or hard water needs a multi-step treatment and adds roughly $100–200 across a whole house. Steep or tall access, and glass above decking, add time as well. Frames, tracks, sills, and screens are included in every visit rather than billed as extras. Two things lower the cost: upkeep is cheaper than a first clean, so homes on a twice-yearly spring-and-fall schedule pay less per visit, and bundling windows with a driveway or roof visit beats paying for two trips. Send a photo of the front of the house and a rough pane count and you will have a flat written price within 24 hours.

A full exterior — siding plus the driveway and walkways — averages around $650 for a typical Seattle home. Booked separately, a standard driveway runs $250–375, and a two-story siding wash lands between $500 and $800. Small single-story homes with straightforward access start near $299; large multi-story properties with extensive flatwork, multiple patios, or long retaining walls run $1,200 and up. The variables that matter are square footage of surface, how many stories, roof pitch where we need to reach above it, and the condition of what we are cleaning — ordinary dirt and algae is a different job from years of oil staining, rust, or thick moss packed between pavers. Heavy oil or rust treatment adds roughly $100–250 depending on spread, since it needs a dwell-and-agitate process rather than a single pass. Note that siding is soft washed rather than pressure washed, which is the correct method for it and not an upcharge. Bundling the whole exterior into one visit is meaningfully cheaper than booking flatwork and siding as separate trips, and Signature Care Plans run about 15–25% below à la carte. Every quote is a flat written price within 24 hours, with nothing added on site.

Neither is better; they solve different problems, and using the wrong one is how homes get damaged. Pressure washing drives water at high force and is right for hard, non-porous surfaces that can take it — concrete driveways, sidewalks, patios, pavers, brick, and stone. Soft washing applies a biodegradable cleaning solution at roughly garden-hose pressure, lets it dwell, then rinses. That is the correct method for anything force would harm: vinyl and fiber-cement siding, stucco, painted wood, cedar shake, and roofs. On siding, high pressure forces water behind panels and into wall cavities, strips paint, and leaves permanent streaking. On a composition roof it blasts off the protective granules and shortens the roof’s life; on cedar it splinters and fuzzes the grain. There is also a difference in how long results last. Pressure washing removes what is on the surface, so mold, algae, and mildew regrow from the roots left behind. Soft washing kills the organism at the root, which is why a soft-washed surface typically stays clean two to three times longer — and in a climate as damp as Seattle’s, that gap is the whole argument. In practice most homes need both on the same visit: flatwork pressure washed, siding and roof soft washed. We choose per surface and sequence it correctly — roof first, then siding, then glass — so nothing gets re-dirtied, and we tell you which method we are using where before we start.

Yes — properly licensed in Washington State and carrying liability insurance on every job. We are happy to send documentation before we start, and we never subcontract your property out to a stranger; the work is done by our own trained professionals.

Twice a year suits most Seattle homes: once in spring after the pollen drops, and once in fall before the winter rain ramps up. Homes under heavy tree cover, near saltwater, or on busy arterials collect film faster and do better on a quarterly schedule. Our deionized-water rinse leaves no mineral spotting, so the glass stays clear noticeably longer between visits than a traditional bucket-and-squeegee clean.

Late spring and early fall are the two sweet spots. Spring works best once the tree pollen and cottonwood have finished dropping — usually late May into June — because cleaning before that just means catching the next wave. Early fall, roughly late September into October, is the more important of the two: it clears summer dust and pollen and gets the glass clean before the winter rain, when you are indoors looking out and daylight is scarce. Hitting both is why we recommend a twice-yearly schedule for most homes. Winter cleaning is perfectly possible here and we do it year-round — our deionized-water rinse dries spot-free even in damp weather — it simply stays clean for less time. The one window worth avoiding is right before a windstorm or a heavy pollen week; if that is in the forecast we will tell you and suggest a better date rather than take the booking.

Roof moss is most of our roof work, and no — our method is specifically designed to avoid damage. We use a low-pressure soft wash that lifts moss without stripping the granules off composition shingles or splintering cedar, then apply a moss-prevention treatment that kills the root system so regrowth is much slower. You also get inspection notes on flashings, valleys, and problem areas, plus a realistic maintenance interval for your particular roof and tree cover.

Most Seattle homes land between $175 and $325, with a typical single-story house around $175–225 and a standard two-story around $250–325. Larger properties, steep or complex rooflines, and homes where ladder access is tight run higher. The main drivers are linear footage of gutter, how many stories, roof pitch, and how much is actually in there — a light needle load is a different job from two seasons of packed, composted debris that has to be bagged and hauled out. Downspout flushing is included in every visit rather than billed separately, because a clear gutter draining into a blocked downspout has not solved anything. Genuinely clogged or disconnected downspouts that need to be opened up add $25–75 each. If your gutters have guards or screens, removal and reinstallation adds time. Heavy moss growth in the gutter line is usually a sign the roof needs attention too, and bundling that into the same visit costs less than two trips. You get a flat written price within 24 hours — a photo of the house from the street is usually enough for us to quote without visiting.

Twice a year is the right default for most Seattle homes: once in late fall after the leaves have finished dropping, and once in spring to clear what the winter blew in along with moss and grit off the roof. Homes with significant conifer cover need more — Douglas fir and cedar shed needles year-round rather than in one clean drop, so three to four visits a year is realistic on the Sammamish plateau, in Issaquah, or anywhere under mature evergreens. Homes with little overhanging tree cover can often stretch to once a year. Skipping to an every-few-years schedule is where it gets expensive: standing water in a packed gutter rots fascia board, overflow saturates the foundation, and in a cold snap ice damming can push water back under the shingles. A cleaning is a small fraction of what fascia replacement or a roof repair costs. If you are not sure what your property needs, we will tell you after the first visit based on what we actually pull out.

Late fall is the single most important window — roughly late October into November, once the deciduous leaves have finished dropping but before the sustained winter rain arrives. Cleaning too early in the fall means the gutters refill within weeks. The second-best time is early spring, which clears winter debris, roof grit, and any moss that has taken hold, and gets drainage working before the spring downpours. If you can only do one visit a year, make it the late-fall one. We work year-round and mid-winter cleanings are common — usually because a gutter has started overflowing and needs clearing then and there — but planned work in dry weather is safer on the ladder and lets us flush and test every downspout properly. We do reschedule for high wind, ice, or heavy rain, since roof-edge work in those conditions is not worth the risk.

Our holiday packages start at $675 per season for a single-story roofline, $1,250 for a full front elevation, and $2,400 for estate properties. Most Greater Seattle homes land between $700 and $1,400 for a first season. Every price is all-in — the lights, custom cutting to your roofline, installation, an energy-saving timer, in-season repairs, takedown, and off-season storage — and because the strands are leased rather than sold, you never pay for inventory you then have to store. The first season costs the most, since measuring and cutting your set is front-loaded work; renewals are lower. See the full holiday lighting service →

On a single-story house with lights that already fit, doing it yourself is reasonable. On a two-story home the calculation changes: December in Seattle means wet shingles, early darkness, and cold hands, which are the worst conditions for ladder work at the roof edge. You are also paying for fit — we cut each strand to the exact length of its run, so lines sit tight to the fascia with no sagging or visible cords, which store-bought fixed-length sets cannot do. Add free in-season repairs if a section goes dark, and a display that disappears in January without you touching it. Compare holiday packages →

Greater Seattle and the Eastside: Seattle, Bellevue, Kirkland, Redmond, Sammamish, Issaquah, Mercer Island, and Shoreline. Each area weathers differently — lake air in Kirkland brings mildew back faster, the Sammamish plateau packs gutters with needles, and Issaquah homes shaded by the Alps hold moss longer — so we tailor the method and the schedule to where you actually live. If you are just outside that list, ask anyway; if we are working nearby that week we can usually fit you in.

Not for exterior-only work — many clients are at work while we are there. Interior window cleaning does require access. Either way, if you are around at the end we walk the property with you so you can point out anything you want redone before we call it finished.

Yes — give $50, get $50. When someone you refer books their first service with us, they get $50 off that job and you get $50 off your next one. There is no cap: refer three neighbors and that is $150 in credit. Just have them mention your name when they request a quote, or put it in the “Referred by” box on the quote form, and we apply both credits automatically once their job is done.

After the work is done, never before. Card, Zelle, Venmo, cash, or check — whichever is easiest for you. We do not ask for a deposit on standard residential jobs and we do not take payment until you have seen the results and signed off.

We come back out. If something gets missed or a result is not what you expected, we redo it before we take payment — that is the whole arrangement, and it is why we do not ask for money up front. In-season touch-ups for plan clients are included.
