Ultra Renovations is a deck builder in Lake Stevens, WA for decks and pergolas, plus deck extensions, stairs, privacy walls and even a pergola for a hot tub. We're owner-led and bilingual, so you can plan your project in English or Spanish.
Before & after
Two carpentry jobs from our crew: a sagging gate swapped for a sturdier one with new hardware, and a Marysville coffee stand given a new subfloor, a reinforced structure and waterproof vinyl plank.

‹ ›BeforeAfterThe Ultra standard
A deck is built outside, but we're still working at your home. Here's how we handle it.
Ultra is owner-led by AJ Lopez Murillo, and you can plan your deck or pergola with us in English or Spanish.
A past deck customer wrote that no shortcuts were taken. That's the bar for our framing, stairs and railings.
People are usually home during a deck build, and we work around the household that lives there.
Our workmanship on decks, stairs and pergolas is backed for three years once the project is complete.

About Ultra Renovations
Owner AJ Lopez Murillo grew up in the Pacific Northwest and worked across the trades, supervising team projects, before building Ultra around one value: professionalism is what separates a great contractor from an ordinary one.
Ultra's first job was a deck built from scratch. Since then, AJ's outdoor builds have included a 13 ft custom pergola with a bar slab and barn door, and a hot tub pergola with high-end panels at Big Lake.

How it works
What happens between your first call and your first evening out on the new deck.
Call (425) 268-0035 or send the form with what you have in mind: a new deck, an extension, stairs, a pergola or a privacy wall.
We visit, measure the space, and talk through size, layout, railings, stairs and how you plan to use it.
We review the estimate and scope with you in English or Spanish. When you approve it, the build begins.
Our crew builds the structure, stains or finishes the wood if that's part of the job, and walks the finished deck with you.

Decks & Pergolas FAQ
Yes. As a deck builder we handle decks, deck extensions, stairs and privacy walls, and we build pergolas too. One backyard project combined a 13 ft x 13 ft x 10 ft custom pergola with a bar slab, a privacy wall and a barn door, plus a 14 ft x 16 ft deck extension.
Yes. For a home in Big Lake, WA, we installed a concrete slab and built a private pergola for the hot tub with high-end panels, plus a slab for drinks.
Yes. We've added a 14 ft x 16 ft extension with a custom decorative privacy wall, and one of the beams underneath can hold a soft swing.
Often, yes, especially for attached or raised decks and decks with stairs. Inside city limits, permits come from the City of Lake Stevens Permit Center; in unincorporated areas, from Snohomish County Planning and Development Services. Ask us about it at your estimate visit.
Keep it swept and sealed, and plan to re-stain once water stops beading on the boards. Rainy winters wear down unprotected wood, and re-staining on time is easier than replacing boards later. We stain existing decks as well as the ones we build.
Most deck work happens outside, and we plan around the people in the house. One deck customer noted that the crew was respectful of someone still living in the home during the project.
It depends on the city's frost depth. Lake Stevens lists a 12-inch frost line in its 2021 residential design criteria, while Monroe lists 18 inches, so check the city where the deck will go. Footing width is set separately by Washington's deck footing table, based on soil bearing capacity, the deck area each footing supports and snow load.
Not a standard deck. Washington's code requires decks to carry a 60 psf live load, and its deck span tables assume 60 psf live load or 70 psf ground snow load. The American Wood Council's prescriptive deck guide says decks supporting large concentrated loads like hot tubs are beyond its scope, so a tub needs its own design.
At least 36 inches. Washington's residential code requires guards on open sides of decks, stairs and landings that sit more than 30 inches above the floor or grade below, measured within 36 inches of the edge. Stair guards can be 34 inches. Edmonds' deck handout adds that intermediate rails must stop a 4-inch sphere from passing through.
In unincorporated Snohomish County, an uncovered deck, porch or steps can project into a required setback if it is no more than 4 feet above finished grade, stays at least 30 inches from every property line and extends no more than 6 feet into a street setback. Taller or covered decks must meet full building setbacks.
Washington's code fastens the deck ledger to the house band joist with 1/2-inch lag screws or bolts spaced by joist span, and the ledger must be flashed to keep water off the band joist. The standard lateral detail adds hold-downs rated 1,500 pounds or more within 24 inches of each deck end. Decks 30 inches or lower may be freestanding.
