Maltby homes, lots and the ground under them
Maltby sits north of Woodinville and south of Snohomish, where State Route 522 meets State Route 524, and homes here carry Woodinville or Snohomish mailing addresses. On our jobs it's mostly houses on roomy lots with long driveways, outbuildings and tree lines, with a small cluster of shops at the center in and around the old Maltby School.
With forest and wetland running south of SR 522 around Paradise Valley, a Maltby yard is often soft, damp or sloped, so much of our work here happens in the digging out and drainage before the pour.
Concrete work we do on Maltby properties
Concrete driveway building
Long Maltby driveways that climb from the road need a dug-out, packed base and a planned path for runoff, so the slab doesn't settle at the low end.
Concrete patio construction
A back patio beside the tree line gets roots, shade and damp soil, so we dig past the soft topsoil and slope the slab away from the house.
Stamped concrete services
Stamped concrete gives a Maltby patio or walkway the look of stone or brick, and we set the cut joints along pattern lines where they blend in.
Concrete sidewalk building
A walk from the driveway to the door, or out to a shop, needs a packed base and a slight slope so water runs off instead of pooling.
Garage floor concrete
When a Maltby garage floor has cracked, sunk or chipped, we break it out, fix the base underneath and pour a new slab that drains toward the door.
Decorative concrete
Colored, exposed-aggregate or patterned finishes suit a front entry or patio on a larger Maltby lot, and we talk through upkeep before you pick one.
Concrete retaining walls
On a sloped Maltby yard, a retaining wall holds back soil to make level room for a patio, with drainage behind it so water doesn't build up.
Concrete floor installation
Shops, outbuildings and basements around Maltby need a level floor, and we set the base, any vapor barrier and the finish to fit how you'll use the space.
Concrete pool decks
A Maltby pool deck needs a finish with grip for wet feet and a slope that carries splash water away from the pool and the house.
Concrete steps construction
Homes on sloped Maltby lots need sturdy steps, and we pour them with even risers and a brushed broom finish that grips underfoot when it's wet.
Slab foundation building
For a new shop, garage or addition on a Maltby lot, we pour the slab foundation over a packed base with steel rebar tying it together.
Foundation installation
New homes, additions and outbuildings here start with a foundation set to the ground they sit on, and sloped or soft spots get extra planning before we dig.
Concrete parking lot building
Small businesses around Maltby's center need parking that carries delivery trucks, so we pour a thicker slab on a deeper base and plan where water drains.
Concrete footings
Decks, posts, sheds and retaining walls on uneven Maltby ground need footings dug to firm soil and set level so the weight above doesn't sink or lean.
Foundation raising
When part of a house or garage has settled on soft or wet ground, foundation raising lifts it back toward level before cracks spread further.
Concrete cutting
We saw-cut old slabs on Maltby properties to remove a damaged section, widen a driveway or open a path for drain lines, so the rest stays intact.

How permits and licensing work for Maltby concrete jobs
Snohomish County sets land use and zoning for the Maltby area, and its Planning and Development Services office issues building permits and clearing and grading permits in the county's unincorporated areas, so that's the office to ask whether your job needs one. The county's residential permit list names work like additions and repairs rather than driveways or patios, so I look at the permit side when I come out for the estimate, and if a permit is needed we prepare and file it and plan the start date around it. The state requires every construction contractor to register with the Department of Labor & Industries and to be bonded and insured, so it's fair to ask anyone you're considering about it. We're licensed and insured. The county itself licenses only a short list of regulated businesses, such as pawnbrokers, so most businesses need no county license, though a job inside Snohomish city limits needs that city's business license for contractors based elsewhere.
What moves the price here is mostly what's under and around the slab, such as how much soft ground we dig out and replace with packed base, how steep the run is, whether an old slab has to be broken out and how far the concrete truck can reach down a long driveway. The schedule turns on the permit, when there is one, and on curing, the days new concrete needs before it can take weight, and I'll walk you through both for your job at the visit. We're a concrete contractor based in Bothell, WA, and we do the same driveways, patios and steps in Lake Forest Park and Kenmore, but the long drives and uneven ground on Maltby lots usually put more of the job into the ground work.
Why Maltby driveways and patios settle and crack
Most of what we're called out for here starts with slope. A driveway that climbs from the road carries runoff down its whole length, and if the old slab went in on dirt that was raked level instead of dug out and packed, the subgrade, the ground the slab sits on, softens until the concrete sinks and cracks at the low end. We dig down to firm soil, build and compact a gravel base, and set the slab to fall away from the house so water leaves instead of pooling against your foundation.
Damp ground and tree roots do the rest. Near the wetlands and tree lines here, roots push up slab edges and soft spots hold water, so I look for both at the visit and plan the base, and sometimes the layout, around them.
What to expect when you hire us for concrete in Maltby
From your first call to the final walk-through, here's how a Maltby job runs and who you'll be dealing with at each step.
Call or send the form
Call (425) 384-1147 or send the form with a few lines about the job, and we'll get back to you to set up a visit. A short description of the space and the address are enough to start.
I visit and write the estimate
I come out myself, look at the slope, soil, drainage and truck access, and ask what the space needs to do. You get a written estimate that spells out what's included and what isn't, so there's nothing left to guess about the price.
We handle permits and pour
If the job needs a permit, we prepare and file it and set the start date around the county's review. Our own crew does the digging out, base, forms and pour, and I lead the work on site.
We walk the finished job
Once the joints are cut and the slab has started curing, I walk the job with you. I'll go over how long to keep feet and cars off it and how to look after the surface.
Concrete contractor questions from Maltby homeowners
How much does a new concrete driveway cost in Maltby?
A Maltby driveway is priced on its size, the base work under it and the finish on top, and the written estimate I give you after the visit spells out each part. Building up a slope or adding a drain line or retaining wall adds to it, while a plain broom finish costs less than stamped or colored work. If the budget is tight, I'd rather you keep the finish simple than thin out the base, because the base is what keeps the slab from settling and it can't be fixed later without starting over.
What causes a concrete patio to crack or sink?
Most cracking and sinking comes from the ground under the slab, usually a base that was raked level instead of dug out and packed, water running under the edges, or joints that were cut late or skipped. Control joints are shallow cuts we make in the fresh slab, so when the concrete shrinks and cracks a little, as all concrete does, it cracks along those lines instead of across the middle. A pour in midday heat can also leave a weak, dusty top, so we time our pours to avoid it.
How long does a new concrete driveway take before I can drive on it?
You can usually walk on a new driveway well before you can drive on it, because the concrete keeps curing and gaining strength for days after the pour. I'll give you the days for your slab when we finish, and keeping cars off until then is the simplest thing you can do to protect it.
Do I need a geotechnical engineer for concrete work on a sloped lot in Maltby?
Yes, when there's a slope of 33% or more on your parcel or within 200 feet of the planned work, because the county requires a geotechnical engineer to evaluate it. Under the county's landslide hazard rules, building in a landslide hazard area is allowed only when there's no other location and code conditions are met, and a covenant stating the hazard and your acceptance of the risk has to be recorded on the property before any permits are issued. State hazard maps only show landslides already mapped, so a slope with nothing on the map can still carry risk, and I look at the grade closely when I come out.
How do I find out if I need Health Department approval for a new slab foundation in Maltby?
If your lot isn't served by sewer, call the Snohomish County Health Department at 425-339-5250 about septic tank requirements, because it has to approve plans for new construction, additions and some remodel projects. We keep slabs and footings clear of the tank and drainfield, so it helps to know where yours are before I come out.
What paperwork should a contractor give me for a concrete job in Maltby?
For any residential job of $1,000 or more, a registered contractor has to give you the state's Model Disclosure Statement Notice to Customer. From us you also get the written estimate, with what's included and what isn't spelled out, so you know exactly what you're paying for.
