Keep 150 Days of Rain Outside — Building Envelope Engineering in Seattle

Curtain walls, cladding, and waterproofing engineered for a city that gets 150 days of rain a year. Norquist designs, tests, and verifies the details that keep the weather where it belongs — outside.

Why Norquist

We Only Do the Envelope. That's the Point.

Most firms treat the facade as a line item between structure and interiors. Norquist treats it as the whole job — because on Puget Sound, the envelope is where buildings succeed or fail. Fourteen years, one discipline: how water, air, heat, and light move through a wall. Our engineers hang off the buildings they assess, spray-test the details they draw, and sign what they seal.

  • Licensed PEs who do their own fieldwork
  • Design-side and forensic-side experience
  • Details contractors price with confidence

How We Work

Survey. Test. Detail. Verify.

The same discipline whether it's a new tower or a sixty-year-old leak — evidence first, drawings second, verification always.

1

Survey & Document

We put eyes — and often ropes — on every elevation, and document the envelope as built, not as drawn.

2

Test & Diagnose

Spray racks, smoke pencils, and moisture mapping isolate the actual failure path before anyone opens a wall.

3

Detail & Specify

Repair and design details drawn at buildable scale, with specs contractors can price without padding.

4

Verify in the Field

Mockup reviews and installation testing confirm the built wall performs like the drawn one — before closeout.

The Seattle Problem

Water Always Finds the Lazy Detail.

Thirty-seven inches of rain a year doesn't destroy buildings — unresolved transitions do. The window-to-wall joint nobody drew. The parapet cap that relies on caulk. Norquist exists for those two centimeters of the building where most of its lawsuits are born.

  • Leak investigations with documented failure paths
  • Repairs designed to the actual cause, not the symptom
  • Litigation-grade reporting when it comes to that
The Norquist Way

Why Our Walls Stay Dry

We Test, Not Guess

Every diagnosis is backed by field measurement — moisture mapping, spray testing, thermal imaging — so the repair targets the real failure, the first time.

Details Drawn to Build

Our details come from people who watch them get installed. If a sequence doesn't work with gloves on at sixty feet, it doesn't leave our office.

Verified at Closeout

We field-test the installed wall against the design intent — so the building you accept is the building we engineered.

The Standard

Every Engagement Gets

Sealed PE Deliverables

Every report, detail, and spec carries a Washington PE stamp — and the professional liability that stands behind it.

Field Testing to AAMA Standards

Water and air infiltration testing run to recognized field protocols, documented so results hold up to any reviewer.

Thermal Bridging Analysis

Envelope assemblies modeled for real heat flow — not catalog U-values — so energy code approval doesn't stall the permit.

Buildable Specifications

Scope language contractors can price tight, sequenced for occupied buildings when tenants are staying put.

Owners Who Stopped Chasing Leaks

Elena Vasquez
Three consultants told us the leaks were 'settling.' Norquist spray-tested the curtain wall, found the failed splice joints in two days, and drew a repair the contractor could actually build. Dry through two winters now.
Daniel Okafor
Their peer review caught a thermal bridging detail that would have cost us the energy code approval. One markup saved the schedule — and about four hundred thousand dollars in redesign.
Priya Raman
The recladding spec was so thorough our bids came back within four percent of each other. No allowances, no surprises, no change orders on the envelope. That never happens.
Questions

Asked Before the First Site Visit

Do you work for owners, architects, or contractors?

All three — on different projects. Owners hire us for assessments, leaks, and recladdings; architects for facade design and energy modeling; contractors for mockup and field testing. On any single project we're clear about who we represent.

What does a facade condition assessment cost?

It scales with elevation count and access. A mid-rise visual survey with a drone runs a few thousand dollars; a full rope-access assessment with intrusive openings on a high-rise is a bigger, phased number. We scope it after a document review and a walk-around — that first look is free.

Can you test an occupied building without disturbing tenants?

Yes — most of our field testing happens on occupied buildings. Spray testing is staged elevation by elevation with notice to affected floors, and interior verification is scheduled around tenant hours. Nobody's workday should end because we found a leak.

What if the test doesn't reproduce the leak?

That's information too — it eliminates a failure path and narrows the search. We escalate methodically: more water, higher pressure differential, adjacent details. Leaks that only appear in a south-westerly with wind-driven rain get tested like it.

Our building is from the 1980s. Reclad or keep repairing?

That's a math question, and we'll show the math: remaining service life of the existing system, repair spend rate, energy penalty, and the capital cost of overcladding versus full replacement. Sometimes the answer is 'ten more years of maintenance' — we'll say so.

Do you handle the permit and energy code side of a recladding?

Yes. Recladding triggers current energy code, and that's where projects stall. We model the proposed assembly, run the compliance path, and sit in the plan-review meetings until the permit clears.
