Exterior Cleaning in Birch Bay, WA

What kind of homes does Birch Bay have?

Mostly detached houses, with a big manufactured-home share and a young median age. The census counts 4,363 single-family detached units and 875 mobile homes out of 5,974 in total, and it puts the median build year at 1990. Growth explains the young median: the population more than tripled between 1990 and 2010, from 2,656 to 8,413.

Older layers are still there. Birch Bay Village, a planned community, broke ground in 1966, and in the 1920s Birch Bay Resort amounted to 12 small cabins. So a single morning on the route can take in a mid-sixties house, a 1990s build and a manufactured home, each with different siding, glass and roofing to think about.

For us the practical upshot is variety. We quote each house on what is actually on it rather than on what the street is supposed to look like.

What does living on the bay do to the outside of a house?

It adds salt and wind to the usual western Washington damp. The shoreline is exposed enough that on January 13, 2021, a storm pairing high wind with a high tide pushed seawater and big driftwood logs at Birch Bay Drive, and stretches near Birch Bay State Park without the berm had water across the road. The county finished a 1.58-mile berm from Cedar Avenue to the mouth of Terrell Creek that August.

Weather that throws logs at a road also throws spray and mist inland. On a house, that shows up in three places:

• Seaward glass picks up a dull film that plain rain does not rinse off
• Siding and trim on the exposed elevation hold grime and salt residue where the eaves do not shelter them
• Gutters and downspouts collect whatever the wind drives onto the roof, which near the water is not only leaves

The landward side of the same house can look fine at the same time. We treat the two faces as different jobs when it saves you money to do so.

How do you look after a home that sits empty half the year?

We plan the visit so you do not need to be there. About one Birch Bay home in five is held for seasonal, recreational or occasional use, and historically many of those owners lived across the border; through the 1970s and 1980s most of the seasonal owners here were Canadian. A cabin that is closed from October to May can go a whole wet season without anyone looking at its gutters.

For absentee owners the usual pattern is simple. We walk the property, send you the quote with photos, agree access and a date, and do the exterior while you are away. Afterwards we can send pictures of the finished work, so you are not relying on a promise. If you want the place cleaned the week before you arrive, say so, and the first evening back is spent on the deck rather than on a ladder.

A closed-up house also benefits from someone noticing things. If a downspout has come loose or a section of moss has gone thick over winter, we tell you rather than leave it for your next visit.

Window cleaning at the bay

Glass is usually the reason people buy here, and it is the first surface the salt dulls. Our window cleaning covers inside and out, screens and tracks, with a water-fed pole for upper floors and anything above a deck.

The pole runs on purified water we carry in the truck. We have not found a published hardness figure for the Birch Bay Water & Sewer District supply, which comes from City of Blaine groundwater, and we are not going to guess one. Bringing our own water makes the question moot for the glass we clean.

Bay-facing picture windows often go on a tighter schedule than the rest of the house. Remote owners who only want the view side refreshed before a visit can book just that elevation.

Gutter cleaning and downspouts

Every trough gets emptied by hand, the fine silt flushed, and each downspout checked to its outlet. That is the core of our gutter cleaning, and on a seasonal home it matters more than on one that is lived in year-round, because nobody is home to see the overflow in December.

Wind-driven debris does not wait for autumn here. Where a lot has trees, needles and leaves add to it; where it does not, blown sand and grit still find their way into the gutter line. We book most Birch Bay gutter work for early autumn, ahead of the wet months, and a second pass in spring where the roof is shaded.

Roofs and moss

We soft wash roofs and lift moss by hand, and we do not put a pressure wand on shingles. Our roof cleaning and moss removal services apply here the same way they do across Whatcom County, with the method set by the roofing material rather than by how green the roof looks.

Manufactured homes deserve their own note. Many have lower pitches and lighter roofing than a site-built house, so we look at what the roof actually is before anyone steps onto it, and some are better cleaned from a ladder and pole than walked. Where a roof should not take foot traffic, the quote will say so.

Moss grows fastest on the shaded pitch. On a house that is empty all winter, the first sign of trouble is often a gutter full of moss clumps, which is worth mentioning if you see it on arrival in spring.

House washing and siding

Siding here collects both the ordinary green growth of a damp climate and the residue that comes off the water. House washing is a low-pressure soft wash: a cleaning solution suited to the siding, time to work, and a gentle rinse. We use it on vinyl, painted wood, fiber cement and manufactured-home panels alike, adjusting the mix and the pressure to each.

Trim, fascia and window surrounds on the exposed elevation are where the salt shows first. A wash of just those areas is possible if the rest of the house is holding up.

Driveways, decks and walkways

Concrete and composite outdoor surfaces go slick with growth wherever shade and moisture sit. Pressure washing covers driveways, paths, patios, steps and decks, with a rotary surface cleaner on flat concrete so the finish comes out even rather than striped.

At a seasonal property the deck and the steps up to the door are usually the priority, because they are what the family walks on in the first hour back. We can do those alone if the drive can wait.

Solar panel cleaning

Panels near salt water gather a film just as the windows do, and a dirty array produces less than a clean one. For solar panel cleaning we use purified water and soft brushes, never abrasives, and we work from the ground or a ladder rather than walking on the panels.

Owners who monitor output remotely sometimes spot a dip before they spot the dirt. If your app shows the array falling behind its usual numbers, a clean is a cheap thing to rule out first.

Which wash-water rules apply in Birch Bay?

Whatcom County’s, because Birch Bay is unincorporated and has no municipal code of its own. Chapter 16.36 of the county code, on illicit discharge detection and elimination, covers unincorporated areas inside Ecology’s Phase II stormwater permit area, and the county’s permit area includes the Birch Bay Urban Growth Area.

Two parts of that chapter shape our work:

1. WCC 16.36.050(C) bars anyone from discharging a pollutant to the county’s storm sewer system or to surface and ground water.
2. WCC 16.36.050(D)(4) treats a routine building wash-down that uses no detergent as a conditional discharge that is not illegal, unless the public works director finds it is causing pollution.

Stormwater in the watershed has had its own management body since March 27, 2007, when the Birch Bay Watershed and Aquatic Resources Management District was set up. Water quality here has a history too: the area around the mouth of Terrell Creek was closed to shellfish harvesting over high fecal coliform, and Birch Bay was added to the state’s threatened shellfish areas list in 2003. The county reports that the Birch Bay Shellfish Protection District was dissolved in July 2026, so the current status of that closure may have changed.

What it means on the job: plain-water rinsing where that is enough, drains protected wherever a cleaning solution is used, and rinse sent to soil rather than to the storm system. The full detail is on our wash water and storm drains page.

Which nearby towns do you cover?

Birch Bay sits in the north-county part of our route, alongside Blaine, Ferndale and Lynden, with Bellingham as the base. We work those towns on a regular rotation, which is why a booking at the bay does not mean waiting for a special trip.

If your property is on the edge of Birch Bay and you are not sure whether it counts, ask. We would rather give you a straight answer on the phone than discover on the day that the drive is further than we planned.

How to book

Call (360) 303-6806 or send a request online. Tell us whether you are living at the property or visiting it, and when you next plan to be there; we will schedule the walk-round and the work around that date.

You will get a quote written for your house and the surfaces on it, and the owner-trained crew who does the work is the same one that turns up on the rest of the north-county route.
