In University Place's aging housing stock, dry rot has had 50–70 years to work undetected through crawl space framing, mudsills, window frames, and siding substrate. APCON LLC identifies the full extent, eliminates the moisture source, and replaces compromised structural members — licensed, permitted, and warranted for 5 years. GC License #APCONL*825QO.

University Place's post-war housing stock presents a specific dry rot profile: homes built before 1975 with original untreated or minimally treated mudsills sitting directly on uncoated concrete, crawl spaces with absent or failed vapor barriers, and 50+ years of Pacific Northwest wet seasons working on framing that was never designed for this duration of service. The decay isn't hidden — it's in the first place any experienced contractor looks. What varies is the extent: mudsill rot that looks contained to one corner is frequently found to extend 8–12 feet laterally once framing is exposed. The forensic diagnostic exists specifically to map this before pricing — not during build.
These are the specific, observable indicators that the structural system has been compromised — not vague warnings, but the exact things homeowners notice and inspectors document.
Probing the sill plate where the house meets the foundation reveals soft, dark, or crumbly wood. This is the single most common structural finding in University Place's pre-1975 inventory.
Pressing on exterior window sills, door jamb bottom rails, or trim boards reveals softness instead of resistance. This indicates decay behind the surface finish that will be flagged on any inspection.
Repeatedly failing exterior paint in specific locations — window sills, corner boards, fascia board ends — is driven by moisture migrating through decaying substrate, not by paint quality.
The characteristic cube-crack pattern of brown rot visible on joists, posts, or mudsills at the crawl access. The wood is brittle and breaks in rectangular blocks when disturbed.
Persistent ground-level odor in first floor rooms, particularly in older areas of the home. Fungal decay produces volatile compounds detectable at low concentration — often before visible damage is apparent.
A record of roof leaks, overflowing gutters, or damaged downspouts over the life of the home. Each uncorrected water event deposits moisture into wall cavities and crawl space framing.
Every structural repair by APCON LLC (GC License #APCONL*825QO) carries a 5-year written guarantee. Fixed-price lump-sum contract. No hourly billing. The $350 forensic diagnostic fee credits 100% toward your repair.
Understanding what actually drives structural failure in Western Washington homes — not surface symptoms, but the underlying conditions that produce them — is what separates a forensic repair from a patch job.
The mudsill — the first piece of framing sitting on the foundation — was the most important piece to protect and the least protected in University Place's original construction. Most pre-1965 mudsills have zero remaining decay resistance.
University Place receives 38–42 inches of annual precipitation with the majority concentrated between October and May. Seven months of sustained precipitation means structural wood that cannot dry out between wetting events accumulates moisture content above decay threshold.
University Place's mature landscaping and aging gutters frequently fail to route roof water away from foundations effectively. Splash-back, clogged gutters, and grade-level downspout discharge keep foundation perimeter wood perpetually moist.
Failed caulking at window frames, disconnected downspouts, and deferred roof repairs create moisture entry points that persist for years in owner-occupied homes that have not had a contractor assessment.

License & Compliance: APCON LLC holds Washington State General Contractor License #APCONL*825QO. All structural framing work falls within the GC scope of practice under WAC 296-200A-016(23). Specialty trade work (plumbing per RCW 18.106, electrical per RCW 19.28) is coordinated under GC oversight with licensed trade contractors only. APCON LLC does not perform or advertise specialty trade work directly.
Dry rot in University Place's housing stock is never an isolated finding. It is a system indicator — when you find dry rot in the mudsill, you find it in the rim joist. When you find it in the rim joist, you find it in the first several joists. The scope cascades unless it is addressed in full at the root cause level. Surface patching or epoxy fill does not resolve section loss in load-bearing wood, and it does not satisfy the disclosure requirements or financing conditions associated with a licensed GC finding.
The transaction implication: a buyer who discovers unaddressed dry rot in a University Place home is looking at a negotiating adjustment of 2–3× the actual repair cost. A seller with a completed, permitted dry rot remediation and a 5-year warranty is in a different transaction position entirely.

In University Place's sustained Pacific Northwest moisture conditions, active fungal decay can progress 2–4 linear feet per year through floor framing when moisture sources are unaddressed. A contained repair today is a fraction of the scope that the same repair requires after two more wet seasons.
Borate-based wood preservatives are a legitimate supplemental treatment for at-risk adjacent framing, but they do not restore structural capacity to decayed wood. Any load-bearing member with section loss requires physical replacement.
Yes. Experienced inspectors in University Place's market specifically probe mudsills, rim joists, and post bases. Fungal decay found during a buyer inspection becomes a material disclosure item with direct transaction impact.
Fungal decay progresses through structural wood from the interior outward — particularly at mudsills, window sills, and rim joists. The exterior paint face can appear intact while the wood substrate has lost 50–60% of its structural section. Probing with a pointed tool is the only reliable surface assessment.
Fungal mycelium can traverse masonry surfaces to reach adjacent wood — this is a known characteristic of certain brown rot species. This is why repair scope must include assessment of all wood adjacent to confirmed decay, not just the visibly affected member.
