- Elevating Exteriors – From Concept to Completion
Conway sits low in the Skagit River delta, wedged between Fir Island farmland and the I-5 corridor that runs past Mount Vernon and Burlington. It is a small, mostly unincorporated community, but it shares the same building climate as the rest of Skagit County: wet winters, open agricultural wind, and in many spots a water table and flood history that homeowners elsewhere in Washington rarely have to plan around. All of that shapes what a deck replacement actually costs here, not just the square footage. This guide walks through realistic price ranges, the local factors that move those numbers, what a trustworthy quote should spell out, and how to compare bids without getting burned. Alpine Exteriors replaces and rebuilds decks throughout Conway and the rest of Skagit, Island, and Whatcom counties, and the ranges below reflect what we typically see on real jobs in this area rather than a national average pulled from somewhere else.
Most full deck replacements in the Conway area land somewhere between a modest low-thousands repair-and-refresh and a mid-five-figure rebuild, depending heavily on size, material, and how much of the substructure needs to be redone. A small, low-to-the-ground deck rebuilt in pressure-treated lumber sits at the low end. A large, elevated deck rebuilt in composite or PVA decking with new footings, engineered railings, and a full tear-off of the old structure sits at the high end. Nobody can give you an honest number without seeing the site, but the table below breaks down the pieces that push a quote up or down so you can gauge where your project is likely to fall before you ever call a contractor.
| Cost Factor | Typically Adds (Low) | Typically Adds (High) | Why It Swings |
|---|---|---|---|
| Decking material | Pressure-treated lumber, lower end | Composite or PVA boards, higher end | Composite and PVA cost more up front but resist the moss, splintering, and rot that heavy Skagit rain causes in treated wood over time |
| Substructure & footings | Reuse sound framing where code allows | Full tear-off with new footings and joists | Ledger boards and posts that have taken years of winter rain often need full replacement, not patching |
| Height & stair runs | Low, single-level deck | Elevated deck with long stair runs | Some Conway lots sit on fill or piers due to the flood plain, so framing height and stair length add material and labor |
| Railing & guard system | Standard wood or basic metal baluster rail | Cable rail, glass panel, or engineered wind-rated rail | Open exposure across the Skagit flats means railings on taller or exposed decks sometimes need extra bracing to meet wind loads |
| Demo & disposal | Small deck, easy access | Large deck, tight or wet-yard access | Hauling old decking and framing off a soggy, low-lying lot costs more than off a dry, curb-accessible one |
| Permitting & site review | Standard residential permit | Floodplain or setback review required | Parts of Conway fall inside Skagit County's mapped flood zones, which can add review steps before framing starts |
A handful of regional realities show up again and again on Conway deck jobs and they are worth understanding before you get a quote, not after.
A vague one-line estimate is the biggest source of disputes and change orders on deck projects. A detailed quote from Alpine Exteriors or any reputable contractor should spell out, in writing, at minimum:
If a quote is missing several of these, ask for them before you sign anything. It is far cheaper to clarify scope on paper than to discover a gap once framing is already open.
Deck quotes are hard to compare fairly because two bids for the same size deck can price out very differently based on what is actually included. Before comparing the bottom-line number, line up each quote's scope side by side: same square footage, same material grade, same substructure work, same permit handling. A lower bid that reuses questionable old framing or skips ledger flashing detail is not actually cheaper, it is just deferring a cost. Confirm every contractor you consider is currently registered with Washington's Department of Labor & Industries and carries active liability insurance, and ask to see it rather than taking it on faith. Alpine Exteriors holds Washington contractor license ALPINI751OW and can provide proof of registration and insurance on request, and any contractor working in Conway should be able to do the same without hesitation.
Many homeowners in Skagit County finance a deck replacement through a home equity line, a contractor-arranged financing partner, or a personal loan, and it is worth comparing terms across more than one option before committing since rates and fees vary. On the insurance side, a homeowners policy typically does not cover the gradual rot, wear, or age-related failure of an existing deck, since that is treated as a maintenance issue rather than a covered loss. Sudden damage from a specific covered event, such as a windstorm or a fallen tree, is a different situation and may be covered depending on your policy, so it is worth a call to your insurer with photos and a written contractor estimate before assuming either way. Do not assume replacement will be covered just because the deck failed suddenly; ask the specific question and get the answer in writing.
A straightforward, at-grade deck replacement typically takes a matter of days to complete once material is on site, while a larger or elevated deck with new footings, stairs, and engineered railings takes longer. Weather is the biggest variable here, since sustained winter rain can push back excavation and concrete work, so timelines are usually more predictable if the project is scheduled outside the wettest stretch of the year.
Most deck replacements of meaningful size require a residential building permit through Skagit County or the applicable local jurisdiction, and decks in mapped flood zones near Conway may also require floodplain development review before a permit is issued. A reputable contractor will know whether your specific property falls inside that mapped area and will handle the application, but it is worth confirming who is responsible for pulling the permit before work starts.
Composite and PVA decking cost more upfront than pressure-treated lumber, but they resist the moisture absorption, splintering, and moss growth that heavy Skagit County rainfall causes in wood decking over the years, and they generally need less ongoing maintenance like staining or sealing. Whether that trade-off is worth it depends on your budget and how long you plan to stay in the home, since wood decking is a legitimate lower-cost option if it is properly flashed and maintained.
Sometimes, if the framing, posts, and footings are structurally sound and code-compliant, but that determination should come from a physical inspection rather than an assumption, since ledger rot and corroded fasteners are common on older decks in this area and are not always visible from the surface. A contractor should be willing to inspect the substructure before quoting a boards-only replacement, and should tell you honestly if what looks like a simple resurfacing job actually needs framing work first.
A deck replacement in Conway is not a project to price from a phone call alone, given how much local conditions like flood-zone framing, ledger moisture, and open-field wind exposure affect the real scope of work. Alpine Exteriors serves Conway and the surrounding Skagit, Island, and Whatcom county communities, and can walk your specific property, explain what your deck actually needs, and put together a detailed, itemized quote so you know exactly what you are paying for before work begins.
