Doors that seal, latch, and last

Entry doors, patio doors, sliders, interior doors, and storm doors installed across Bellingham and Whatcom County.

A door is more than a hole in the wall

An exterior door is a weather seal, a security barrier, and often the first thing a guest touches. When it’s installed poorly it drafts, sticks, and lets water into the framing around it. When it’s installed well you almost never think about it.

We install exterior and interior doors across Whatcom County — pre-hung units, custom slabs into existing jambs, patio sliders, and full French door assemblies. Every exterior install gets proper pan flashing, weather-stripping, and a threshold set to shed water away from the house.

What's included

Entry Doors

Fiberglass, steel, and solid wood front doors installed to seal properly.

Patio & Sliders

Sliding glass, French, and multi-panel patio doors.

Interior Doors

Passage, closet, pocket, and barn-door installs throughout the home.

What we offer

Entry Doors

The front door sets the tone for the whole house. We install fiberglass units for low-maintenance performance, solid wood for traditional Whatcom County craftsman homes, and steel for security-focused applications. Every install includes proper flashing and a weather-tight threshold.

Patio Doors

French patio doors, out-swing single doors, and multi-panel folding units — we install them all across Bellingham. Patio doors need a wider rough opening and careful header work, which is why they’re often left out of DIY window projects.

Sliding Doors

Modern sliders are a huge step up from the aluminum units common in older Whatcom County homes. New vinyl and fiberglass sliders seal properly, run on true ball-bearing tracks, and include integrated security features.

Interior Doors

Bedroom, closet, pantry, and utility doors — we install them as part of remodels or as a stand-alone refresh. Sliding barn doors, pocket doors, and glass French doors are all options for interior spaces.

Storm Doors

A well-installed storm door protects the entry door from wind-driven rain and adds a second layer of insulation. We install full-view, mid-view, and retractable-screen units matched to the entry door behind them.

Frequently Asked Questions

Can I keep my existing hardware?2026-09-09T13:25:06-07:00

Sometimes. If the hardware is high quality and the bore pattern matches the new door, absolutely. We’ll tell you before install if the transfer will look clean.

What about security features?2026-09-09T13:24:52-07:00

We install multi-point locking hardware, reinforced strike plates, and full-length hinge screws on entry doors. Simple upgrades that make a real difference.

Do you install pocket doors?2026-09-09T13:24:39-07:00

Yes — as part of remodels where we can open the wall, or in new-construction and addition framing where the pocket is planned from the start.

How much does an entry door install cost?2026-09-09T13:24:31-07:00

A quality pre-hung fiberglass entry door installed runs $1,800 to $4,500 depending on the door itself. Custom wood or wide French units run higher.

Can you install a door in an existing opening?2026-09-09T13:24:18-07:00

Almost always, yes. Pre-hung units drop into the existing rough opening. Slab-only installs into existing jambs work when the jamb is square and sound.
