Pergolas, covered deck roofs, code-compliant railings, built-in benches, planters, lighting, and stairs that finish out a deck and make it usable in our rainy months. Railings get checked against current code.
A deck in Bellingham gets a lot more use when there's a roof over part of it. We build pergolas and covered deck roofs that let you sit outside through the gray months, plus the pieces that finish a deck out: code-compliant railings, built-in benches and planters, deck lighting, and stairs. These are the add-ons that turn a bare platform into a space your family actually uses October through March.
Railings are the one we take seriously, because they're a safety item and the city checks them. We bring railings up to current code on height, baluster spacing, and load, whether it's a new deck or an old one that never met code. Most add-ons run $2,500 to $20,000 depending on scope, and a lot of them get bundled into a new build or a rebuild. Tell us what you're picturing and we'll scope it.

Frequently asked questions.
How much does a pergola or deck add-on cost in Bellingham?
Most deck add-ons in Bellingham run $2,500 to $20,000 depending on scope. A code railing run is at the low end, a full covered pergola is at the high end. Stairs, benches, planters, and lighting fall in between. We scope it on-site and give you a line-item quote.
Do you bring old railings up to code?
Yes. A lot of older Bellingham decks have railings that don't meet current code on height or baluster spacing. We rebuild them to code, which matters both for safety and if you ever pull a permit or sell the home.
Can a pergola work in our wet weather?
It can, and a covered roof is even better for the rain. We build pergolas and covers sized for our wind and rain loads, tied into the deck framing so they hold up. A covered section means you can use the deck through the gray months, not just summer.
