Sheds, enclosures and detached garages in Northwest Washington

Sheds, equipment enclosures and detached garages, built to sit right on your lot and look like part of the house. We work across Skagit, Snohomish, Island and Whatcom Counties, from shed kits on a gravel pad to insulated buildings on a poured slab.

An insulated lean-to shed in Clinton, built to drawn plans by a crew we hired and supervised.

What this covers

  • Storage sheds, built on site or assembled from a kit
  • Lean-to sheds against the house
  • Enclosures for equipment such as propane tanks and water-treatment systems
  • Detached garages and shops
  • The base: gravel pads, pressure-treated runners and poured slabs
  • Siding, roofing, trim and gutters to match the house
  • Insulation where what's inside needs protecting
  • Lights and outlets, which can stay with us under our residential electrical license

How we handle a shed or garage

At the site visit we look at where it will sit, what it needs to hold, how you'll get in and out, and where the water goes. That decides what goes underneath. A kit shed can sit on a gravel pad and pressure-treated runners, while an insulated shed or a garage usually sits on a poured slab.

We draw the plans, and the written proposal lists the base, framing, siding, roofing, doors, trim and gutters line by line. Siding and trim can be matched to the house, and doors and windows are weather-sealed.

During the build you get dated progress photos, and any change goes in a signed change order. At the end we walk it with you.

Questions people ask

Can a shed match my house?

Yes. We can match the siding, trim color and roofing to the house so it blends in, as we did on the Clinton lean-to with fiber-cement siding.

Do you assemble shed kits?

Yes. Pick the kit you like, and we'll assemble it, set it on runners or a pad, and weather-seal the doors and windows.

Can you build a detached garage or shop?

Yes. We look at the site with you, then put the slab, framing, roof, siding, doors and any wiring in one written proposal. The wiring can stay with us under our residential electrical license.

Can a shed protect equipment like a water-treatment system?

Yes. That's what the Clinton lean-to was built for: insulated, vapor-sealed walls and ceiling, a slab floor and weather-stripped doors.
