Homes in Bothell

Bothell has a small historic core around Main Street with older homes from the early 1900s, but most houses here date from the 1970s through the 2000s. North of I-405, Canyon Park, North Creek, Thrasher’s Corner and the Queensborough area are full of two-story subdivision homes with hardboard or fiber cement siding, attached decks and builder-grade trim. Westhill and Maywood have more 60s and 70s split-levels and ramblers on wooded lots. Many homes have tight side yards and backyards that slope toward greenbelts. Newer townhomes and apartments are concentrated near downtown, Canyon Park and the North Creek business parks.

Bothell sits in the Sammamish River and North Creek valleys, with hills rising on both sides. The valleys hold fog and damp air on winter mornings, while the hillsides have heavy tree cover and greenbelts that keep walls and decks shaded. Tight lot spacing in many subdivisions means side walls rarely dry out. Long, wet winters soften hardboard siding and trim, and builder-grade flashing from the 80s and 90s is reaching the end of its useful life.

Canyon Park and North Creek on the Snohomish County side have big 80s and 90s subdivisions where hardboard siding and nailed decks are aging out. Westhill and Maywood, south of downtown, are hillier and older, with mature trees and shaded lots. Homes near the Sammamish River and in the valley get more fog and dampness. Thrasher’s Corner and Queensborough have newer homes on tighter lots, often backing onto greenbelts with heavy shade.

Common problems

What we fix most in Bothell homes

Balcony & Porch Repair

Rotted balconies, porches, columns and railings rebuilt safely and waterproofed. In Bothell, that usually means balconies, porches and columns take weather on every side and rot at the connections.

Dry Rot Repair

We find where the water gets in, cut out every soft spot and rebuild it so it stays dry. In Bothell, that usually means small paint cracks turn into soft, spongy wood behind the paint.

Siding Repair & Replacement

Siding repair and replacement with the house wrap and flashing done right behind it. In Bothell, that usually means water gets behind older siding at every window, corner and roof line.

Every visit starts with a free inspection: we probe the wood, check moisture, photograph what we find and give you a written price before any work starts. Small like-for-like repairs often don’t need a permit, but structural work, new decks and larger replacements usually do. Permits come from the City of Bothell for homes in both the King County and Snohomish County parts of the city. We check with the City of Bothell before starting so your project is handled correctly.

Maintenance

A year-round checklist for Bothell homes

Fall

  • Clean gutters and downspouts before the first big storms
  • Check deck boards, railings and stairs before they get slick
  • Look over window sills and trim for cracked paint

Winter

  • Watch for stains on ceilings under decks and balconies
  • Note any spots where water pools against the house
  • Check that downspouts drain away from the foundation

Spring

  • Walk the house and press trim, sills and corners for soft spots
  • Wash moss off siding, decks and roofs gently
  • Book repairs early: summer schedules fill fast

Summer

  • Repaint and recaulk while the wood is dry
  • Reseal wood decks and recoat balcony surfaces
  • Replace rotted wood before the rain comes back

Bothell gets the same long wet season as the rest of the region, so most exterior damage builds slowly from October to May. A short walk around the house each season catches problems while they are still small.

How it works

From first call to finished repair

1

Probe and document

We test soft areas with an awl and a moisture meter and photograph everything before we quote.

2

Find the leak

We trace where the water comes from, so the repair fixes the cause, not just the wood.

3

Cut out all the rot

Damaged siding, sheathing and framing come out back to solid, dry wood.

4

Rebuild and flash

New framing and sheathing, house wrap, and the flashing that was missing.

Warranty

Backed by a 24-month workmanship warranty

Written scope

You know exactly what is included before work starts, with photos of what we found.

Our own crew

The people who quote your job are the people who do it, start to finish.

Clean site daily

Debris is hauled away and your yard is left the way we found it.

24 months covered

If our workmanship fails within two years, we come back and make it right.

FAQ

Questions from Bothell homeowners

Do you work in Bothell?
Yes. Bothell is part of our regular service area in King and Snohomish counties, and we can usually schedule a free inspection within a few days.
What do you repair in Bothell?
Rot, decks, siding, structural framing, waterproofing and flashing, windows and trim, chimney chases, fascia and soffits, balconies and porches.
Is the estimate free?
Yes. We inspect, take photos and give you a written price at no charge.
Are you licensed and insured?
Yes. Eco Home Repair LLC is licensed, bonded and insured in Washington (License #ECOHOHR774PU).
Do you serve both the King County and Snohomish County sides of Bothell?
Yes. Bothell spans both counties, and we work throughout the city, from Westhill and Maywood in King County to Canyon Park, North Creek and Thrasher’s Corner in Snohomish County. Permits for homes in either part of the city come from the City of Bothell, and we handle that process for you.
Why is the hardboard siding on my Bothell home swelling?
Hardboard siding swells when water gets into its edges or through failed paint, which is common on 80s and 90s Bothell homes. Once swollen it softens and rots. We replace damaged boards with matching material or fiber cement, add flashing and house wrap behind them, and seal and paint so the repair holds up.
Can you repair a 25-year-old deck on my Bothell home?
Often yes. Many original decks in Bothell subdivisions have solid footings and some sound framing, but rotted joists, boards or ledgers. We inspect everything, repair what can be saved, replace failing parts, and add ledger flashing. If the deck is too far gone, we can build a new one in composite or cedar.
