ABOUT ANOKA
What we see on Anoka homes
WATER
Six wells, four treatment plants
Nearly all of Anoka is on city water from six deep wells, and all four of its plants filter out iron and manganese. Filtering iron does not soften water, so the hardness stays. Hard water that dries on a home leaves its minerals behind as white spots on glass and a dull film on siding. Deposits left through a few summers bond to the glass and become much harder to remove, so spots are best treated while fresh.
TREES
A Tree City USA community
Anoka is in its 41st year as a Tree City USA community and cites diseased trees citywide, with emerald ash borer confirmed in Anoka County. Mature trees shade roofs and north walls, so those surfaces stay damp long after rain, which is where algae and mildew start. Their leaves settle in gutters and on roofs, where they hold moisture against the surface. Spring and fall gutter cleaning keeps that moisture off the roof edge.
RIVERS
Where the Rum meets the Mississippi
Anoka sits at the confluence of the Rum and Mississippi Rivers, which the city calls two of its greatest natural resources. Humid air near two rivers keeps roofs, siding and decks damp, which is where algae, mildew and moss take hold, usually on the shaded north side first. A soft wash, matched to each surface and applied at low pressure, kills that growth; on roofs, the rain often does the rinsing.
HOMES
Older homes, median 1973
Anoka's homes are older than most in the north metro: the median was built in 1973, and 11% date to 1939 or earlier. That means older paint, wood trim, storm windows and brittle screens. Decades of sun chalk and thin old paint, and high pressure can lift it or force water behind aging trim. These homes are washed gently at low pressure, with the mildest mix of all on painted surfaces.

ANOKA WATER
How Anoka water marks a house, and what helps
Anoka removes iron from its city water but not the hardness, so the marks on a home here can come from more than one source. Here is how to tell them apart, and what helps with each.
Two kinds of mineral stain
Orange and brown streaks on siding, brick and concrete are iron or manganese. Anoka filters both out of city water, so here they usually trace to a private well, lawn fertilizer or rusting metal rather than the tap. White spots on glass come from the city water itself, which stays hard and leaves its calcium behind as it dries. Two sources, two problems, and two different treatments.
Why bleach makes rust worse
Bleach is the usual first instinct, and on rust it is the wrong one. Bleach is an oxidizer: on rust, it oxidizes the iron further and sets the stain. Iron comes out with acid-based chemistry that dissolves it or binds it into a form that rinses away. Acid and bleach must never meet, mixed or one after the other without a full rinse, because together they make chlorine gas.
What prevents most of it
Aim every sprinkler head at the grass, never the house, and keep hose spray off siding and glass. Anoka filters iron out of city water, so when orange stains show up, look first at fertilizer, rusting metal or a private well. Most lawn fertilizers contain iron, and granules thrown onto a driveway or walk leave small orange spots once they get wet.
How we clean with your water
We connect to your outside spigot and run the water through reverse osmosis, carbon and deionization filters in our van until it reads 0 PPM (parts per million of dissolved minerals). Water with nothing in it cannot spot as it dries. Hard water wears the filters out faster, so we check the meter as we go, and the filter resin is replaced before the next job once a reading reaches 15 PPM.
THROUGH THE YEAR
A year of home care in Anoka
SPRING
Clear the winter
Pollen and winter film come off the glass, and spring gutter cleaning clears seeds and catkins. Branches trimmed back from the roof let it dry faster, which slows algae and moss.
SUMMER
Watch the sprinklers
Anoka's odd/even schedule runs from June 1 to September 1, with no watering from 10 a.m. to 7 p.m. Aim the heads at the lawn, and treat new stains early, before they bond.
FALL
Gutters before the freeze
Gutters are cleaned once the leaves are down and before the first hard freeze, so wet debris does not freeze in place. Exterior cleaning wraps up November 15.
WINTER
Ice dams and lights
When storms create ice dams, they are removed with steam only, which melts the ice rather than chipping it. Roofline holiday lighting installs begin November 1, with takedown and storage included.
ANOKA QUESTIONS
Questions from Anoka homeowners
Do you serve all of Anoka?
Glass House serves every neighborhood in Anoka. The business is based in Ham Lake, and Anoka is part of our regular north metro route, so there is no trip fee. Every visit starts with a quick walk-around, so the method and the mix suit the age and surfaces of your home before any work begins.
Can you clean my windows with Anoka water?
Yes. We connect to your outside spigot and run the water through reverse osmosis, carbon and deionization filters in our van until it reads 0 PPM, meaning no dissolved minerals are left to spot the glass. Hard water wears the filters out faster, so we check the meter as we go. Please make sure the spigot is turned on and easy to reach.
Why are there orange stains under my windows?
Orange stains under windows are usually iron, carried by sprinkler or hose water and left behind when the water dries. Anoka filters iron and manganese out of city water, so orange staining here often traces to fertilizer, rusting metal or a private well rather than the tap. It takes an iron-specific, acid-based treatment, never bleach, which sets the stain. The sooner it is treated, the better it comes out.
How often should a house in Anoka be washed?
Most homes in Anoka should be washed every year or two. Homes near the Rum or the Mississippi, and homes on shaded lots, should be washed every year, because algae and mildew return faster where siding stays damp. Older painted homes receive the mildest mix and a short dwell time, which is how long the solution stays on before it is rinsed.
How do quotes work?
To request a quote, send a photo or book a walk-around. Every online quote is verified in person before the work starts, so Carson can confirm the surfaces, including any aged paint or brittle screens, and bring the right mix for each one. You will have the exact price before any work begins, and nothing starts until you have agreed to it.
When is your season?
Exterior cleaning runs March 1 through November 15. Roofline holiday lighting installs begin November 1, so the two overlap in the first half of November. Through the winter, ice dams are removed on call with steam only, and interior window cleaning remains available.
Who does the work?
Carson Brenny, the owner. Glass House is owner-operated, with no crews or subcontractors, and is insured to $2M. The person who quotes your Anoka home is the person who cleans it and walks the finished job with you, so the standard does not change from one visit to the next.
What if the weather turns?
Weather reschedules are always free and never count as a cancellation. We send a text the day before with your arrival window, and another when Carson is on the way. For any other change to an appointment, please let us know at least 48 hours in advance, as the service policies explain.
THE OWNER
Why Carson takes the gentle route in Anoka
Glass House belongs to Carson Brenny, who runs it himself from Ham Lake, with no crews, subcontractors or handoffs. Anoka is part of his regular route. He has worked full-time in exterior cleaning since 2020, and on every Anoka home he quotes the job, does the work and walks the result with the homeowner before calling it finished.
Anoka's homes are some of the oldest on the route, with a median build year of 1973, on tree-shaded streets where the Rum meets the Mississippi. Older paint, trim and screens call for an especially careful hand, so Carson takes the gentle route and explains what he sees, because for most families, the house is their largest investment.
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.”
Carson Brenny, owner
