Synapse Construction - Seattle Siding and Windows

This is the kind of detail most people would never notice — which is exactly the point.

That white panel on the right is a door being fitted to match the horizontal siding depth on the surrounding wall. The goal: when it's done, the door surround reads as a seamless part of the facade rather than something bolted onto it.

Our crew spent time at a recent management meeting walking through exactly how they're calibrating the depth to achieve that match on this Lake Washington waterfront build. Getting it right requires precision at every course — because even a few millimeters off throws the whole plane.

Nobody sees the work that goes into making something look effortless. That's what craftsmanship actually is.

This is what we found behind the stucco at a deck-to-wall transition.

The exterior looked fine. No obvious signs of failure from the outside. But once we opened it up, the damage told a different story — years of water finding its way in at the junction between the deck and the wall, with nowhere to go.

This is one of the most common failure points we see on Seattle homes. Deck-to-wall connections require proper flashing, waterproofing, and drainage details to perform long term. When those details are missing or fail, water infiltrates slowly — and by the time it shows up inside, the damage behind the wall is already extensive.

The plastic sheeting you see is us protecting the opening while repairs are underway.

If your home has a deck attached to the house, it's worth having the transition inspected — especially before fall rains arrive. We're scheduling summer assessments now.

From outdated to modern.

This Seattle exterior renovation completely transformed the look and performance of the home with updated siding, trim, waterproofing details, and modern architectural finishes.

A successful exterior project is about more than curb appeal — it’s about creating a durable building envelope designed for the Pacific Northwest climate.
