Why it matters
Rot, rusted hardware and weak connections often hide under the surface. NADRA’s numbers show why regular inspections matter:

What we inspect
We follow the structure of NADRA’s deck evaluation, working from the ground up.
Are the footings sound and the posts properly sized, attached and free of rot, notching or splitting?
We check beams, joists and the hangers and connections that tie them together.
Where the deck attaches to your house — one of the most common failure points. We look at fasteners, flashing and water damage.
Soft, cracked, rotted or loose boards and the fasteners holding them down.
Stringers, treads, risers and the stair’s connection to the deck and landing.
NADRA names handrail failure as the largest source of deck injuries — we test every post and rail for strength and safe spacing.
Correct fasteners in the right places, and signs of corrosion on nails, screws, bolts and connectors.
A clear verdict: what’s safe, what needs attention soon and what should be fixed before anyone uses the deck.
Warning signs
If you notice any of these, stay off the affected area and have the deck inspected before you use it again:
Good times to inspect
Know exactly what shape the deck is in before closing — or fix issues before a buyer’s inspector finds them.
May is NADRA’s National Deck Safety Month® — a good reminder to check your deck before cookout season.
Freeze-thaw cycles, heavy snow and storms are hard on footings, ledgers and fasteners.
If you didn’t build it, don’t know when it was built, or it has never been checked, it’s time.

Inspection questions

The North American Deck and Railing Association (NADRA) is the trade association for the deck and railing industry. Its members include deck builders, inspectors, manufacturers, dealers and lumberyards, and it promotes safe building practices through programs like National Deck Safety Month® and its Deck Evaluation certification.
NADRA’s Deck Evaluation certification trains industry professionals in a systematic approach to assessing deck construction and safety, and requires passing NADRA’s exam. The certification is valid for three years and requires current NADRA membership, so it has to be kept up to date.
No. We tell you what we find and what it means. Plenty of decks only need small repairs — and if yours is in good shape, we’ll say so.
Yes. Because we build and repair decks too, we can quote any repairs right away. You’re never obligated to hire us for the work.
Call, text or use the form on our contact page and choose “Deck inspection.” We’ll set up a time that works for you.
