Structural Problems
Don't Wait
Every one of these symptoms is a structural system communicating that something has failed or is actively failing. None of them resolve on their own. Delay increases repair scope — in most cases significantly. Homeowners searching for structural repair near me or structural repair contractors near me in the Tacoma area have found the right page.
Floor Feels Soft or Spongy
You feel give when you walk across a specific area. Classic indicator of joist deflection, partial rot, or subfloor delamination.
Sagging or Uneven Floors
Marbles roll one direction. Furniture rocks on a flat surface. Visible slope across a room. Load path failure or beam sag.
Bouncy, Springy Subfloor
Floor bounces when you walk near center spans. Joists are under-sized, over-spanned, or have lost cross-bearing connections.
Doors Sticking or Not Latching
Interior doors that bind seasonally or won't latch year-round can indicate foundation settlement or structural frame movement.
Visible Cracks in Drywall
Diagonal cracks at window and door corners, or horizontal cracks in walls, indicate differential movement in the structural frame.
Visible Rot in Crawl Space
Dark discoloration on joists, soft spots when probed, white or black fungal growth on framing. Active rot requires immediate scope assessment.
Musty Odor from Below
Persistent musty smell in the first floor — especially near exterior walls — is fungal activity in the crawl space framing. The source must be found and stopped.
Beam Visible Sag or Twist
A carrying beam that is visibly bowed, twisted, or separating from its posts is a structural priority. It will not recover on its own.
What We Repair —
Directly as GC
All structural work below is performed directly by APCON LLC under WA GC License #APCONL*825QO. No subcontractors on structural scope — this is our core trade.
Structural Beam Replacement
Sagging carrying beams, failed flush beams, undersized spans. We shore, remove, and replace with correctly sized engineered lumber or dimensional stock — with post bearing corrected.
- Temporary shoring installation
- Failed beam removal & disposal
- Engineered or dimensional lumber replacement
- Post bearing & footing verification
- Joist hanger hardware re-installation
Floor Joist Sistering
The most efficient structural repair when joists are deflected but not fully compromised. A full-length sister bears the load while restoring the structural plane of your floor.
- Full-length sister joist installation
- Blocking and bridging restoration
- Subfloor re-fastening as required
- Bearing correction at sill and beam
- Moisture barrier inspection concurrent
Floor Joist Replacement
When rot, pest damage, or physical failure has compromised the full joist depth, sistering is not sufficient. We replace fully — including bearing plate and hardware.
- Full joist removal including rot excision
- Treated lumber where moisture exposure exists
- Sill plate assessment concurrent
- Vapor barrier repair in affected area
- Subfloor & finish floor re-integration
Sill Plate & Rim Joist Repair
Where the framing meets the foundation. Sill plate rot is among the most common structural failure in Tacoma's moisture climate — and is always repairable.
- Full rot excision — no partial cuts
- Pressure-treated sill plate installation
- Rim/band joist replacement concurrent
- Sill seal and anchor bolt restoration
- Drainage source correction recommended
Post & Column Replacement
Point loads need full bearing columns. Rotten or failed posts transfer their failure to the beam above. We replace post and verify the footing beneath before re-loading.
- Post bearing assessment before removal
- Treated or composite post installation
- Post base hardware — code compliant
- Footing adequacy check concurrent
- Temporary shoring during replacement
Subfloor & Structural Sheathing
Water damaged, delaminated, or rot-compromised subfloor. We replace only what is actually compromised — with correct adhesive, fastener pattern, and seams over bearing.
- Full delamination mapping before scope
- Tongue-and-groove subfloor replacement
- Adhesive and screw fastening pattern
- Underlayment re-integration
- Finish floor transition management
Forensic First,
Rebuild Second
We do not enter a repair job with pre-loaded assumptions about scope. Every structural failure has a root cause. Finding it before we open the floor is what separates a permanent repair from a recurring one.
Book a $350 Forensic Diagnostic
One call or message. We schedule within 3–5 business days for non-emergency structural issues, sooner for active failures. The $350 fee is credited 100% toward your repair. Why we charge for diagnostics instead of giving free estimates →
Root Cause Assessment On-Site
We access crawl space, probe framing, check bearing conditions, trace moisture paths, and evaluate load transfer. We do not give you an estimate based on a 10-minute walkthrough.
Written Findings Delivered
You receive a documented report: what failed, why it failed, what conditions allowed it to fail, and a photo-supported written scope. This document is yours regardless of whether you hire us.
Lump-Sum Proposal — Fixed Price
One number. Not a range. Not an estimate. A fixed lump-sum that covers all labor and materials for permanent repair. You approved it before we start.
Permitted Repair Execution
We pull required permits, execute the structural repair, and document the completed work. Every repair is photograph-documented at each stage — for your records, your insurer, and your future buyer.
5-Year Written Guarantee Issued
After project completion you receive a written 5-year guarantee. Same structural problem from our repair — we return, we fix it, no charge. No paperwork. One call.

Fixed Right.
Fixed for Good.
Structural repairs fail when the root cause is not addressed. We have seen it — a joist sistered over a wet sill plate that continues to wick moisture, a beam replaced without correcting the drainage that saturated the original post. The repair looks correct. It isn't.
Our process requires that we identify and address the reason the structural failure occurred — the water source, the drainage failure, the inadequate bearing condition — before or concurrent with the structural rebuild. When both are corrected, the failure cannot return.
We back that standard with a written guarantee. If the same structural problem recurs from our repair within five years, we come back and make it right. No paperwork. No runaround. One call.
