Pick the Repair Type
That Matches Your Symptom
Each guide is based on actual jobs we've performed in Tacoma, Pierce County, and the South Sound. The scope tiers show how pricing scales from spot repair to major structural rebuild. If your situation doesn't fit neatly into one bucket, the $350 diagnostic figures out exactly where it lands.
Dry Rot Repair Cost
Dry rot ranges from a single rotted window sill to a full structural rebuild with siding replacement. Scope tiers move from spot repair through medium section rebuilds to major multi-area structural work.
- Spot repair (single window / fascia section)
- Medium section (rim joist, multi-bay sheathing)
- Major multi-area (structural members + siding)
- Real Tacoma range: $1,500 – $15,000+
Sill Plate Replacement Cost
Mudsill and sill plate replacement pricing is driven by perimeter length, crawl space access, number of bearing points requiring temporary shoring, and whether rim joist replacement is concurrent.
- Partial sill replacement (single run)
- Corner or multi-run replacement
- Full perimeter replacement with rim joist
- Real Tacoma range: $7,500 – $12,000+
Floor Joist Repair Cost
Floor joist repair ranges from a single sistered joist to full section replacement with subfloor and beam work. Access conditions and moisture remediation scope drive the higher end.
- Single joist sistering (small repair)
- Multi-joist sistering with subfloor patching
- Full section rebuild with subfloor & beam
- Real Tacoma range: $750 – $18,000+
No Free Estimates.
Here's Why That Protects You.
Free estimates look attractive until you understand how they get priced. Contractors who show up for free have to recover that cost somewhere — usually by padding the bid, underbidding and generating change orders, or walking after a quick eyeball estimate that misses the real problem. Our $350 forensic diagnostic eliminates all three failure modes.
Free Bids Bias High
A contractor giving free bids has to recover his windshield time somewhere. Either he pads every bid by $200–$500 to cover the ones that don't close, or he undershoots and writes change orders once the walls are open. Either way, you pay.
Pay for Accuracy. Credit Back on the Repair.
You pay $350 for a real on-site forensic diagnostic. We map the full scope, document with photos, and write a lump-sum fixed-price bid. If you proceed with the repair, the $350 credits 100% against your project total. You only pay it if you walk.
No Hourly. No Change-Order Roulette.
Every Realty Repair Co. contract is lump-sum fixed-price. Scope is locked at signing. Material substitutions or owner-requested scope changes get a written change order with fixed pricing. No open-ended hourly billing on residential repair work.
Written Guarantee on Structural Work
All structural repair work carries a five-year written guarantee. That's only possible because the diagnostic maps the full scope before the bid is written. You can't guarantee work you didn't scope correctly.
