Siding installation and replacement that protects the building envelope and holds its color through Oregon's wet seasons.

Windows and Doors

Window and door replacement that improves insulation, stops drafts, and seals out moisture.

Targeted repairs to rotted trim, damaged fascia, and failed flashing before small problems turn into bigger ones.

Exterior Work Built for Willamette Valley Weather.

We choose materials and installation methods that stand up to Lane County's wet winters and overcast, moisture-heavy climate. That means proper flashing and moisture barriers behind siding, rot-resistant decking and fasteners, and window and door openings sealed the right way from the start. On a lot of older Springfield and Eugene homes, we see water finding its way in around trim that was never flashed correctly in the first place. We build so that doesn't happen on your house.

Exterior Construction Questions from Springfield Homeowners.

  • What siding and decking materials hold up best in this climate?

    We lean on fiber cement siding and rot-resistant or composite decking for most Lane County projects. These materials shrug off moisture and freeze-thaw cycles far better than untreated wood, which soaks up water, swells, and eventually rots or warps in our wet winters.

  • How do you keep water from getting behind new siding or windows?

    It comes down to what you don't see once the project is finished. We install moisture barriers and proper flashing behind every siding job, and we seal window and door openings correctly during installation. That layered system is what actually keeps water out, not just the finished look.

  • How long does a typical deck or siding project take to finish?

    A standalone deck usually takes one to two weeks. A full siding replacement typically runs three to six weeks depending on the size of your home. Weather and permitting can push either timeline out, so we build some flexibility into every schedule we give you.

  • Do I need a permit for a new deck or window replacement?

    It depends on the scope of work and your local jurisdiction. Some smaller window swaps don't need one, while new decks and larger replacements usually do. We handle the permitting process ourselves as part of the project, so you don't have to track it down.
