WHAT WE COVER
Deck Inspection Services
Across Seattle
We define all six parts of the Seattle deck inspection scope before work begins. Your written estimate spells out the included work, and your workmanship warranty terms are written into your agreement.
We spell out the project scope in a written estimate before work starts, and your warranty terms are written into your agreement.
01 / DECK INSPECTION
Structural Integrity Check
Our inspection covers twelve review points: ledger attachment, joists, beam connections, post anchors, footings, board attachment, guard height, baluster openings, stair stringers, tread securement, corrosion and spans. We explain concealed areas and calculation limits. The NADRA deck evaluation guide provides an industry checklist; an inspection is not automatically an engineered certification.
02 / DECK INSPECTION
Ledger Board Assessment
Review the ledger connection, flashing, fastener corrosion and the house rim area where accessible. Specify ledger attachment separately from lateral-load connections. Simpson Strong-Tie DTT2Z is a tension-tie option for a designed lateral-load connection, not a universal substitute for the ledger fasteners or an automatically strongest system. Our inspection findings are based on the connections we find at your deck.
03 / DECK INSPECTION
Footing & Soil Review
Confirm footing dimensions, depth, bearing and connections using appropriate records or an agreed investigation. A probe alone may not establish all details. A universal thirty-inch pass/fail depth is not sufficient. If correction is needed, compare engineered pier or helical-pile solutions for the actual soil and loads.
04 / DECK INSPECTION
Railing Code Compliance
Check the applicable guard and handrail requirements, openings and connection details. We check the 36/42-inch heights, four-inch opening rule and 200-pound load figures in context, including stair exceptions and building classification. Do not perform an improvised proof-load test on a potentially unsafe guard.
05 / DECK INSPECTION
Moisture & Rot Probe
Agree on moisture measurements and probing at suspect boards and joists. Ten-to-fifteen readings may be an initial scope to discuss; the actual assessment follows conditions and access. Photograph findings, locations and limitations, and avoid treating a meter reading alone as a complete decay diagnosis.
06 / DECK INSPECTION
12-Point Written Report
We prepare a PDF report with findings, photographs, relevant code references where appropriate and repair/replacement recommendations and estimates. We go over the report format and delivery timing when you schedule. If a buyer, lender or insurer will receive the report, let us know when you call so we can plan the format with you.
Not sure exactly what you need?
Start with a site assessment and ask what is included in a free inspection before scheduling.

WARNING SIGNS
When Your Deck
Should Be Inspected
These seven situations can justify a deck assessment. Distinguish a contractor’s repair estimate, a home inspection and an engineer’s structural evaluation so the report fits its intended use.
Deck materials and construction details to consider for your project.
01
Buying a home with an existing deck (pre-purchase)
Before purchasing a home, include the existing deck in due diligence and clarify whether the inspector is qualified for the requested report.
02
Selling a home and need disclosure-ready inspection
For a sale, discuss known deck concerns and appropriate documentation with the transaction professionals. A report does not replace applicable seller disclosures.
03
Insurance request after wind, snow, or storm damage
Ask the insurer what documentation it needs after wind, snow or other storm damage. Agree on photographs, scope and limitations before ordering the report.
04
Visible damage (rot, loose railings, sagging boards)
Visible rot, a loose railing or sagging boards warrant assessment. Restrict use of an apparently unstable area until it can be evaluated safely.
05
Deck is 10+ years old without recent inspection
A decade without a recent assessment is useful history, not a safety threshold. Condition and original construction matter on younger decks too.
06
Planning to add hot tub, grill station, or heavy load
Evaluate a proposed hot tub, grill station or other heavy addition before loading the deck. A routine visual inspection may need to be supplemented by engineering.
07
WUI fire-zone compliance documentation required
Verify whether wildland–urban interface requirements apply to the property and the proposed work. Define the actual material and documentation requirements rather than assuming every Seattle deck is in a WUI zone.
Discuss your deck inspection options.
Describe the property, existing deck and preferred timeline. We’ll confirm a visit time that works for you.
REPAIR OR REPLACE?
Repair or Replace
Your Seattle Deck?
Sometimes a few boards are the whole problem. Sometimes the boards are hiding a frame that is done. The free estimate tells you which one you have, before you spend anything.
01 / REPAIR
Repair makes sense when…
The damage is in a few boards, one railing or one set of steps, and the joists, beams, posts and ledger underneath are solid. You keep the frame and pay only for what failed. Deck repair in Seattle ↗
02 / REPLACE
Replacement makes sense when…
Rot has spread into the joists or the ledger, the deck sags or bounces, or the same spots fail every year. A new deck resets the clock and lets you change the size, layout or material. Deck replacement in Seattle ↗
Not sure which one you need?
We check the frame at the free estimate and tell you what we find.

SEATTLE PERMITS
Does a Deck Repair After Inspection
Need a Permit in Seattle?
Most deck repairs are boards, railings and stairs. Seattle’s building department (SDCI) requires a permit to build a deck that is more than 18 inches above the ground, a roof deck, or a deck in an environmentally critical area, and we tell you at the free estimate whether your repair needs one.
Source: Seattle SDCI deck requirements.
01 / HEIGHT
More than 18 inches above the ground
Measured from the ground to the deck. Lower decks do not need a permit unless one of the next two cases applies.
02 / ROOF DECKS
Built on top of part of the building
Every roof deck needs a permit, and it goes through the full addition or alteration permit.
03 / CRITICAL AREAS
In an environmentally critical area
Such as landslide-prone or flood-prone ground. The city visits the site before any permit application.
04 / MOST DECKS
A quick field-inspection permit
Most Seattle decks need only a subject-to-field-inspection permit. The full addition or alteration permit applies above 8 feet, with beams 14 feet or longer, solid decking or more than 750 square feet.
We check the permit at your estimate.
If your project needs one, it goes into your written scope.

PACIFIC NORTHWEST DECK INSPECTION
Inspected for Seattle
Rain, Moss and Salt Air
Rain, evergreen shade, seasonal freeze–thaw conditions and Puget Sound salt exposure all belong in a Seattle deck inspection assessment. Moss and slow drying can hide moisture problems around board ends and structural connections.
For shaded or north-facing decks in Fremont and Ravenna, inspect moisture retention and ventilation. Waterfront properties around Magnolia and Alki may need additional attention to corrosion. Sloped or elevated sites in Queen Anne and Capitol Hill call for a close review of supports and access. We confirm the actual conditions at each address.
- Compatible stainless or coated fasteners. Select for the lumber treatment, connector and exposure.
- Appropriately treated framing. Use ground-contact-rated material where the assembly and exposure require it.
- Joist and ledger moisture protection. Detail flashing, drainage and protection tape as part of the repair.
- Finishes suited to the site. Confirm any marine-grade or waterfront coating against the product’s approved uses.
Read the background on deck construction and repair and the Seattle SDCI deck requirements.
Plan for repeated Seattle rain, shade and drying conditions at the actual property. Specify corrosion-compatible stainless or coated fasteners as part of the complete lumber, connector and exposure design.

BBB Accredited Business. Free phone consultation, no obligation.
A deck inspection in Seattle is free with your on-site estimate. If the inspection finds a problem, repairs start at $199, with up to 25% off qualifying projects.
We can discuss the price of a Seattle deck inspection after defining the assessment and access. A standard twelve-point review, moisture investigation and more detailed structural assessment involve different work; your quote should identify the report and any specialist evaluation required.
Confirm inspector qualifications, access, probing, report detail and intended use before comparing fees. A repair estimate and a transaction-ready professional report may be different services.
No. The inspection visit is free with your estimate, and there is no obligation.
Yes. The on-site estimate is free and comes with no obligation. You get a written price and decide on your own time.
Tell us the size of the deck and what you see, and send photos if you have them. That is enough to talk through the likely scope on the phone. The exact number comes from the free visit, because rot, footings and framing hide under the boards.
If your project needs a Seattle permit, we tell you at the estimate and include it in your written scope. Most decks need only a subject-to-field-inspection permit from Seattle SDCI.
We can agree on the inspection appointment and report delivery date before the visit. Single-level, multi-level and hillside decks need different access and assessment time; discuss whether moisture testing or structural evaluation changes the report scope.
We confirm the appointment length and report delivery date with you before the visit. Size, access, concealed construction, testing scope and any engineering follow-up can change those timings.
The twelve topics are ledger attachment, joist condition, beam connections, post anchoring, footing depth, deck boards, railing height, baluster spacing, stair stringers, tread fastening, corrosion and spans.
Ask what can actually be observed or measured, whether calculations are included and what requires invasive investigation or engineering. A useful written report records limitations as well as findings; compare the NADRA deck evaluation guide for broader evaluation context.
Ask your real-estate and legal advisers which inspections, disclosures and contract conditions apply to the transaction. A pre-listing review can help identify repairs before negotiations, but it does not replace required disclosures.
Buying a home with a deck? We can discuss your pre-purchase questions and the deck assessment you need. For a professional home inspection, check the Washington Department of Licensing requirements and the inspector’s actual credentials.
Ask your insurer whether it will accept the proposed inspector and report before commissioning it. Document observed damage, photographs, assessment limitations and estimated repair scope as requested.
If your policy is with State Farm, Allstate, USAA or another insurer, ask whether the proposed report meets its requirements. We can discuss the deck inspection scope; cause of loss, coverage and claim approval remain the insurer’s decisions.
The ledger connection is an important point to inspect alongside supports, joists, guards and stairs. Corroded hardware, inadequate attachment, missing flashing and hidden rim damage can contribute to problems.
We can discuss the complete house-to-deck connection, including ledger attachment and lateral-load connections. The deck’s age or the absence of one branded part does not diagnose the condition; the assessment needs the actual fasteners, wood and connection details. Simpson Strong-Tie DTT2Z is a tension-tie option for a designed lateral-load connection, not a universal substitute for the ledger fasteners or an automatically strongest system. Assess the complete connection rather than diagnosing failure from one missing branded part.
Our registration is on file with Washington Labor & Industries. Our Washington contractor registration number is listed at the bottom of every page.
We carry $1 million in general liability insurance, and a certificate is available for your project. We are a BBB Accredited Business.
Ask for written coverage of framing, ledger attachment, footing connections, railings and stairs, together with exclusions, claim steps and any transfer rights on sale. Talk with us about the workmanship coverage for your project. Only the contractor’s written warranty establishes the duration and coverage.
We can review Trex, TimberTech and IPE material coverage separately from workmanship coverage. Match the exact product, collection, purchase date and installation requirements to the manufacturer’s current warranty, then confirm the contractor’s written terms for the agreed work.
