Why it matters
A railing that fails isn't just an eyesore — it's a liability.

Updated railing transforms the entire look of an existing deck
Combined with resurfacing, it's a full visual refresh at a fraction of full replacement cost
FAQs
Can you replace just the railing without touching the deck surface?
Yes — railing replacement is a fully standalone service.
What railing system holds up best in Seattle weather?
Powder-coated aluminum is the strongest long-term performer in PNW conditions — impervious to moisture and rust-resistant for the life of the deck.
How long does railing replacement take?
Most projects are completed in one day. Larger perimeters or combined resurface projects may run two days.
