What Homeowners Say
Real reviews from our Google profile — unedited, from real projects.
“We recently had Paul with GP General repair a damaged corner protector and sidings. His estimate was reasonable, his availability was timely, and his job was excellent. Our home hadn’t been re-painted in a while and the paint had considerably faded, yet he was able to match the color perfectly. Now we know who to turn to when in need of another repair work.”
“GP General replaced LP siding on our garage. Paul was very thorough when he came out to do the estimate; he listened to my concerns and was able to work out solutions on the spot. His crew did a great job and were very courteous. They also were careful about cleaning up (I didn’t find any nails!). Really happy with the job and can recommend GP General.”
“I highly recommend GP General Corp for siding replacement. We recently had our wood siding replaced with James Hardie lap siding, and Paul and his team did an excellent job.”
Why GP for decks
Decks built by the crew that keeps walls dry
A new deck should add years to your house, not quietly subtract them. We’re an Everett exterior contractor first — siding, flashing, water management — so we build decks the way we build walls: drainage-first, flashed, and documented.
Then we finish them in TimberTech composite that won’t splinter, rot, or ask for a weekend of staining every other summer.
Typical tired wood deck
Composite rebuildWhat we build
Deck work around Everett
From tear-off rebuilds to second-story decks, every project gets the same standard details: flashing-taped ledger and joists, proper post bases (never buried posts), stainless or coated fasteners, and our 20-point final walkthrough.
Deck rebuilds
Tear off the failing deck, fix what it did to the house, rebuild in composite. Our most common deck job — and the one where siding expertise matters most.
New composite decks
Engineered framing, TimberTech surfaces, hidden fasteners, stairs and landings — built to the plan set when there is one, built like there is one when there isn’t.
Elevated & structural
Second-story and walkout decks, structural posts and beams, engineered footings. We work from stamped plans and pull the permits.
Re-decking
Sound frame, tired surface: new composite decking and railings over your existing structure — the budget path to a new-deck feel.
Free on-site assessment
Get a real deck number, not a teaser
Free on-site assessment anywhere in Snohomish County: a written line-item quote, honest re-deck vs. rebuild advice, and a free photorealistic rendering of the deck on your actual house.
Choosing boards
Composite, PVC or wood? How they compare here
We install TimberTech PRO capped composite — the sweet spot for Puget Sound — and TimberTech’s Advanced PVC line where budgets allow, over engineered pressure-treated framing with hidden fasteners. Weighing brands too? Read our honest TimberTech vs Trex comparison.
| TimberTech PROCapped composite · our standard | TimberTech Advanced PVCPremium PVC · the AZEK line | Cedar or pressure-treatedTraditional wood | |
|---|---|---|---|
| Core | Wood fiber and polymer, sealed in a protective cap | Fully synthetic PVC — no wood fiber to absorb water | Natural lumber; open grain takes on water |
| Warranty | 25–30 year product and fade & stain coverage, by collection | Lifetime limited product + 50-year fade & stain | Rarely backed long-term |
| Wet-climate durability | Very good — the cap keeps water out of the core | Best — nothing organic to rot | Needs sealing; shade and moss shorten its life |
| Upkeep | Soap and water, no staining | Soap and water, no staining | Restain a flat deck every 2–3 years |
| Heat underfoot | Average — lighter colors stay cooler | Select colors engineered to run cooler | Varies by species and stain color |
| Installed with GP | $70–95/sf typical new deck, all-in | Premium board — priced above composite | Lower day-one cost, higher upkeep over time |

One family, one crew
James Hardie now owns TimberTech. We install both.
In July 2025, James Hardie — the company behind the siding we install every day — completed its acquisition of AZEK, the maker of TimberTech decking. Your walls and your deck now come from the same manufacturer family.
As a James Hardie Select Contractor who installs TimberTech, we’re exactly the contractor that combination was built for: one crew, one accountability, one standard of installation across your whole exterior. (The two contractor programs are still separate — there’s no combined certification.)
The detail that matters
Where most decks fail — and where we’re strongest
Most deck failures don’t start in the deck — they start at the ledger, where the deck bolts to your house. Building that connection right is siding work, and it’s the exact detail on every engineered deck plan we build from.
- 1Siding cut backSiding comes off where the ledger lands, so wood never traps water against the wall.
- 2Sheathing checked & replacedRotted sheathing behind an old ledger is cut out and replaced before anything bolts to it.
- 3Membrane + metal flashingSelf-adhered membrane behind the ledger and a drip-edge flashing over it, lapped under the house wrap.
- 4Ledger bolted to the rim joistFastened through to the house framing per the plan — never just nailed through siding.
- 5Hangers + joist tapeJoists hang in metal hangers, and butyl tape caps every joist top to keep the frame dry.
- 6TimberTech surfaceHidden fasteners, code-correct gapping, a clear gap at the wall and matching fascia.
Railings
Railings that fit the house — and the view
Guardrails are code above 30 inches, and they’re half the look of the deck. We build four ways, and bring samples to your assessment.
Cedar
Our signature: real wood warmth, built on site with a wide cap — about $28–30 per linear foot in materials.
Stainless cable
Cables nearly disappear — the view-keeper for water and mountain decks, marine-rated by nature.
Glass panels
The cleanest sightline plus a windbreak on exposed decks. Wants the occasional wash.
Aluminum & composite
Clean, low-maintenance railing systems in black or white that pair naturally with composite boards.

Permits, handled at cost
In unincorporated Snohomish County, a deck needs a permit unless it’s under 30 inches above grade, freestanding, and not serving an exit door; the City of Everett runs its own permit desk with similar thresholds.
- Anything with guardrails (required above 30″) or a ledger connection is permit territory
- Reviewed under the 2021 residential code
- We coordinate drawings and pull the permit — the fee is a pass-through line, never marked up

Common questions
Everett deck building — FAQ
How much does a 20×20 deck cost in the Everett area?
A 400 sq ft TimberTech composite deck typically lands between $28,000 and $38,000 installed — framing, decking, standard railing, and a stair run included. Elevated or structural versions run more. Size-by-size numbers are on our deck cost page.
Do I need a permit to build a deck in Washington state?
Usually yes. In Snohomish County a deck escapes permitting only if it’s under 30 inches above grade, freestanding from the house, and not serving an exit door. Attached decks, decks with guardrails, and rebuilds with structural work are permit projects — we pull the permit at cost as part of the job.
Should I repair my deck or rebuild it?
The honest test is the frame: if the ledger, posts, and joists are sound, new decking and railings (re-decking) buys you a new deck feel at $55–75/sf. If there’s rot at the ledger or in the posts — which is where decks usually fail — a rebuild is the responsible call, because surface boards over a failing frame are cosmetics on a safety problem. We tell you which one you need at the free assessment, and we’re equipped for either.
Why TimberTech instead of Trex?
Both are quality products. We standardized on TimberTech for Puget Sound because its better lines cap the board on all four sides — meaningful in a climate with 37 inches of sideways rain — and because James Hardie now owns TimberTech, which puts your deck and your siding in the same manufacturer family. Full comparison here.
How long does a deck build take?
A straightforward re-deck runs about a week. A full rebuild with new footings, framing, and stairs typically runs 2–3 weeks on site, plus permit review time before we start. Weather matters less than you’d think — composite installs fine in Puget Sound winters, which is also when our schedule is most flexible.
Do you build the railing too?
Always — guardrails are code above 30 inches and they’re half the look of the deck. Cedar is our signature (real wood, built on site, $28–30/lf in materials), and we also install composite and aluminum railing systems and cable or glass railing where a view deserves to stay visible.
