Where We Work:

Seattle Neighborhoods

At Synapse Construction we serve homeowners and contractors across Seattle’s distinctive neighborhoods — from Magnolia to Capitol Hill, Ballard to Queen Anne, and beyond. Whether you need siding repair, water-intrusion mitigation, or full building-envelope restoration, our Seattle team delivers fast response, meticulous workmanship, and durable solutions tailored to the Pacific Northwest climate.

Eastside Communities

Synapse Construction provides building envelope repair, siding services, waterproofing, and leak investigation throughout the Eastside — including Bellevue, Kirkland, Redmond, Issaquah, and surrounding communities. From modern homes to older properties with aging exterior systems, we help Eastside homeowners and contractors identify moisture intrusion issues and deliver durable, code-compliant repairs designed for the Pacific Northwest climate.

Greater Puget Sound Communities

We also cover a wide service area across the Puget Sound region — from Edmonds and Mukilteo in the north, to Kent and Black Diamond in the south, and Bainbridge Island, Lake Forest Park and surrounding suburbs. If you’re outside Seattle and need trusted building-envelope repair, siding replacement, waterproofing or emergency leak response, Synapse Construction brings the same quality, reliability, and local expertise your Seattle neighbors expect.

Mercer Island

Waterfront weather and shade demand materials that shrug off moisture while keeping a refined look. We recommend fiber‑cement lap or panels with factory coatings, metal accents, and careful integration at decks and fascia. Expect meticulous caulking, flashing, and venting to protect sheathing and interiors. If you’re also updating glazing, we coordinate trim, returns, and sills for a crisp finish. See options and request a site visit via our window replacement page.

We integrate rainscreens, proper flashing, and long‑life finishes so your exterior looks sharp and stays dry. Metal and fiber‑cement panel systems pair well with Northwest modern architecture, while updated trim profiles elevate traditional homes. Expect tidy job sites, tight timelines, and thoughtful material guidance to fit your design goals. See options, warranties, and a step‑by‑step process on our metal siding installation page.

Medina

Medina homes deserve exterior systems that balance refined curb appeal with low maintenance. We recommend fiber‑cement or metal options that keep lines crisp and resist moisture year‑round.

If you’re refreshing a classic façade or modernizing a waterfront view, we’ll match materials to architecture and HOA expectations, then deliver a neat, on‑schedule install. Start with a balanced material plan and pricing on our siding installation in Seattle page.

Bellevue
