House washing in Ham Lake, MN
The green on the north side of your house is not dirt. It is organic growth, and it is alive.
Green and black growth on Ham Lake siding is algae, mildew and lichen, growing where shade keeps the wall damp, and homes near Coon Lake, Lake Netta or Ham Lake stay damper still. Glass House kills it at the root with a soft wash, a cleaning solution that does the work so no force ever touches the siding.
The Honest Results Standard targets roughly 90% improvement on normal organic buildup, without risking the siding to chase the last few percent. Oxidation, rust and deep stains are separate treatments, and Carson Brenny, the owner, points them out at the walk-around before any work begins.

HAM LAKE SPECIFICS
What house washing means in Ham Lake
The local conditions that shape how Glass House approaches house washing in Ham Lake, and the standards it holds to on every visit.
LAKES
Coon Lake, Lake Netta, Ham Lake
Part of Coon Lake lies within the city of Ham Lake, Lake Netta sits in its northern end, and Ham Lake itself lies east of Highway 65. Air near open water holds more moisture, so roofs, siding and decks dry slowly after rain and morning dew. Algae, mildew and moss take hold on surfaces that stay damp, usually beginning on the shaded north side. Homes near water grow algae fastest, which is why we recommend a house wash at least once a year there.
TREES
Oaks protected by a no-cut season
Ham Lake protects its oaks with a no-cut period from April 1 through July 15 to slow the spread of oak wilt. Oak shade keeps roofs and siding damp long after rain and dew, which gives algae, moss and lichen the moisture they need. Oak leaves, catkins and acorns pack gutters, and wet debris left on a roof holds moisture against the shingles and feeds further growth.
HOMES
A median home built in 1994
The median Ham Lake home was built in 1994, and about 45% of homes date from the 1990s and 2000s. After about three decades of sunlight, the surface of vinyl siding, painted trim and gutters breaks down into a chalky film, a process called oxidation. Rain running over the chalk leaves streaks, and the roughened surface gives dirt and algae a better grip. Siding that age is checked for loose panels, aged paint and old caulking, which can call for a damage waiver.
WATER
A private well at every home
Ham Lake has no city water system. Every property runs on its own private well, on a lot of at least one acre, so sprinklers apply groundwater exactly as it leaves the ground. Minnesota groundwater commonly carries dissolved iron and hardness minerals. When sprinkler spray dries, the water evaporates and the minerals remain: iron oxidizes into orange stains on siding and concrete, and calcium leaves white spots on glass. A house wash will not lift orange iron stains, which need their own treatment because bleach sets rust.

HOW WE WASH
Chemistry does the work. Pressure never touches your siding.
A pressure washer runs 3,000 to 4,000 psi. Our soft wash system runs 50 to 300, comparable to a garden hose, so the solution does the cleaning and nothing is stripped, etched or driven behind your siding.
01
Everything is rinsed first
Before any solution goes on, plants, windows and anything not being cleaned are wet down, and they stay wet during and after the wash. Drift that lands on a pre-wet surface is diluted to the point of being harmless, which is why landscaping comes through a soft wash well.
02
A mix matched to your siding
The solution is sodium hypochlorite, similar to a diluted household bleach, and its strength depends on the surface. Vinyl, painted wood, stucco, brick, stone and composite each receive their own mix, always starting with the lightest the surface will take and reapplying rather than going stronger.
03
Dwell time, watched closely
Dwell time is how long the solution stays on the wall before rinsing: about 5 to 10 minutes on vinyl, and only 3 to 5 on paint. Carson's field rule is simple: algae that turns brown is coming down, and algae that turns black is going to come back. Green algae usually fades right away.
04
A thorough, low-pressure rinse
Everything put on the siding either stays there or comes down, and bringing it down takes a great deal of water. The system moves 11 gallons a minute, so each wall is rinsed completely, with no chemical left behind to discolor the surface.
FOR HAM LAKE HOMES
What to know before your visit
SPRING
Pollen and winter grime
Spring pollen is the most common reason a house washed last year looks dirty again, and winter salt spray, sand and road film come off in the same visit.
SUMMER
Worked in sections
Heat makes the cleaning solution work faster and dry faster, so on hot days walls are pre-wet and washed in sections, and the solution never dries on the siding.
SPRINKLERS
Keep the siding dry
Aim every sprinkler head at the lawn, never at the house. A drier wall grows less algae and mildew, and keeping spray off the siding stops new iron stains from forming.
HOW OFTEN
Every year or two
Most homes need a wash every year or two. Lake lots and heavily shaded homes need one at least once a year, because damp air and shade bring growth back faster.

House Washing (Soft Wash) typically runs $450–$700 — $450 for a 2,000 sq ft home and $700 for a 4,000 sq ft home. That's standard siding, and bigger homes go up from there. Carson confirms the exact price after he looks at it.
House Washing (Stucco/Brick/Stone) typically runs $675–$1,050 — $675 for a 2,000 sq ft home and $1,050 for a 4,000 sq ft home. Yours depends on the home, so Carson confirms the exact price after he looks at it.
THE OWNER
Soft washing the homes Carson grew up around
Glass House is based in Ham Lake, the town where Carson Brenny grew up. He owns and runs the business himself: there are no crews, subcontractors or handoffs, and he has worked full-time in exterior cleaning since 2020. He quotes the house, mixes the solution for your siding, washes it and walks it with you when the work is finished.
Ham Lake homes sit among oaks, Coon Lake and Lake Netta, and every property runs on a private well, so one wall can carry green algae and orange iron at once. Carson names each before he starts, soft washes the growth at 50 to 300 psi and keeps the plants wet. Nothing on the property should be harmed getting the house clean.
IN CARSON'S WORDS
“It's my neighbors' homes: their biggest investment, one of the places they spend the most time, and where the people they care about most live. It's something everyone should enjoy, and I believe that.”

WHAT IS INCLUDED
What a house wash includes and leaves out
A house wash is maintenance cleaning for organic growth and everyday grime. Stains and damage are separate services, and we identify them before we start.
INCLUDED
In every house wash
• Soft wash of siding, soffits, fascia, eaves and trim
• Algae, mold, mildew, pollen, cobwebs and bug residue removed
• Plants and windows wet down before, during and after
• The lightest mix each surface will take, stronger only if needed
• Roughly 90% improvement on normal organic buildup
• Before and after photos with your receipt
NOT INCLUDED
Specialty work, quoted separately
• Oxidation, chalking and color that has faded out
• Iron, rust and manganese stains
• Artillery fungus, paint stains and failed coatings
• Tiger stripes on gutters
• Deep staining in porous surfaces
• Inspecting or repairing outdoor outlets and fixtures
EQUIPMENT AND METHODS
Chemistry does the work, not pressure
The soft wash system moves 11 gallons a minute at 50 to 300 psi and reaches 85 feet from the ground, so most homes are washed without a ladder touching the siding. The mix is sodium hypochlorite, similar to a diluted household bleach, at the lightest strength each surface will take. Surfactant, an additive that makes a mix cling, is left out of most house washes because it takes far more water to rinse off; it is added only when a home is heavily landscaped.
HAM LAKE QUESTIONS
House Washing in Ham Lake: FAQ
Do homes near the water in Ham Lake cost more?
No. Being near Coon Lake, Lake Netta or Ham Lake does not change the price, and those homes are quoted the same way as any other in Ham Lake. We do recommend house washing more often there, because humid air keeps surfaces damp after rain and morning dew, and damp surfaces are where algae and mildew grow back fastest.
Do you serve all of Ham Lake?
Yes, every neighborhood. Glass House is based in Ham Lake, so homes here are the shortest drive on the route and there is never a trip fee. Carson often works within a few miles of where he grew up, and he quotes, cleans and walks every job himself.
Will soft washing hurt my plants or lawn?
No. Everything we are not cleaning is rinsed before, during and after the wash, so any drift lands on a wet surface and is diluted to the point of being harmless. If you have prized plants or a koi pond, tell us when you book and we will take extra care around them.
Is soft washing the same as pressure washing?
No. Pressure washing cleans with force, at around 3,000 to 4,000 psi. Soft washing cleans with chemistry and rinses at 50 to 300 psi, comparable to a garden hose. Force is what strips paint, etches siding and drives water behind it, and it does not kill growth at the root, so the growth returns.
Do you need my water?
Yes. We connect to your outside spigot, so it needs to be turned on and easy to reach, not shut off at the inside valve or behind a locked gate. This matters most in spring and fall, when a winterized spigot can be opened only from inside the house. Where there is no outside water, a water tank can be brought to the site.
My siding looks chalky. Will washing fix it?
Washing removes the loose chalk, but faded vinyl does not regain its color, because the color has faded out of the material itself. To check, hose the wall down: if the color comes back rich while it is wet, oxidation removal can recover it. We confirm this at the walk-around, before any work starts.
