Deck builder services in Fort Collins
Fort Collins deck projects mostly fall into three groups: a new deck on a newer house that came with a bare patio slab, a rebuild of an old wood deck whose frame has gone soft, or shade over the deck or patio that already exists. The nine services people ask for most are below; the rest are in the list under them.

Frost, 30 inches down. Fort Collins sets its frost depth at 30 inches, so piers under a deck attached to the house go at least that deep; a freestanding deck can sit on 12 inch piers. Larimer County uses the same 30 inches everywhere outside city limits. Shallow footings are the usual reason an old deck pulls away from the house after a few winters, and the footing depth and snow load guide lists every number the nearby towns publish.
Snow and wind. The City's residential design snow load is 35 pounds per square foot on the ground, which matters most when a roof goes over the deck. West of Overland Trail the City maps winds above 140 mph, where a steel deck needs an engineer. When the roof of a covered deck or a pergola on a deck rests its weight on the deck framing, Fort Collins wants stamped plans; posts carried down to their own footings avoid that.
Sun, hail and dry air. At about 5,000 feet, strong sun and very dry air pull the moisture out of unsealed wood, and Colorado ranks second in the country for hail insurance claims. That is why so many Northern Colorado homeowners pick capped composite, and why a cedar deck here gets sealed every year or two. The composite vs wood guide weighs both.
Permits for more than new decks. In Fort Collins, swapping out joists, posts, beams, stairs or the guard railing needs a permit too, not only a new build. Most deck repair in Fort Collins beyond loose boards is permitted work, and the Fort Collins deck permit guide walks through the plans the City wants.

How a Fort Collins deck build runs
A composite deck installation, a deck replacement and a second story deck follow the same five steps. A hot tub deck adds an engineer before the permit, and railings follow the railing and stair code.
- 1Measure and sketch
Size the deck around how it will be used, mark where it meets the house, and check the lot: setbacks, the slope, window wells under the deck footprint, and any HOA design rules.
- 2Draw it to code
Fort Collins wants a site plan, a framing plan, a side view and connection details. Hot tubs, stacked decks and covers resting on the deck need an engineer's stamp, so those are flagged now.
- 3Permit, then footings
Once the permit is issued, pier holes are dug 30 inches deep for an attached deck and inspected open, before any concrete goes in.
- 4Frame and inspect
Posts, beams, joists, the flashed ledger and the lateral connections go in, and the rough-frame inspection happens before a single deck board covers them.
- 5Boards, rails, final
Decking, stairs, landings and railings go on, then the stair light and the final inspection. A wood deck gets its first coat of sealer once the boards have dried.

Fort Collins and Northern Colorado
The base is Fort Collins, from Old Town and the CSU neighborhoods to the newer subdivisions south of Harmony Road. Around it are eight towns with their own building departments and rules: south to Loveland and Berthoud, east to Timnath, Windsor, Severance and Johnstown, north to Wellington, and west to Laporte, where Larimer County's wildfire code applies.
Each town page says which office issues the permit and what that office publishes for frost depth, snow and wind. Full service area

About Pineridge Deck Pros
Pineridge Deck Pros is a deck company named for the pine-dotted ridge along the west edge of Fort Collins, below Horsetooth Reservoir. It sticks to what goes on the back of a house: decks and stairs, the railings around them, and the covers, pergolas and screens that make them usable in July sun. Concrete patio slabs, fences and sunrooms are other trades, so they aren't offered here.
Prices on this site name their source and year, and rules quote the City or county document they come from. Where a town doesn't publish a number, the page says to confirm it with that town's building office. More about us
Deck Builder in Fort Collins: Common Questions
What is the average cost of a deck in Colorado?
A new deck in the Denver market averages $9,640, and most land between $5,055 and $14,243, according to Angi's 2026 figures for Denver, the TV market Fort Collins belongs to. Per square foot that is about $22 to $55 installed. Pressure-treated wood sits at the low end, capped composite like Trex at the high end, and stairs, railings, height and covers push a deck up the range. Quotes vary by site.
How much would a 14x20 deck cost in Fort Collins?
A 14 by 20 foot deck is 280 square feet, so at Angi's Denver-area rate of $22 to $55 per square foot installed it comes to roughly $6,160 to $15,400. A low, freestanding pressure-treated deck with one short stair lands near the bottom; a composite deck attached to the house, with aluminum railings and a full stair to the yard, lands near the top. The City's deck permit adds $110 plus sales tax.
Do you need a permit to build a deck in Fort Collins?
Usually yes. Fort Collins requires a permit for any deck that is attached to the house, more than 30 inches above grade at any point, larger than 200 square feet, or serving the front door, and for replacing joists, posts, beams, stairs or guard railing. The permit costs $110 ($38.50 plan check plus $71.50 permit) plus sales tax. A small, low, freestanding platform can be exempt.
What is the most expensive part of building a deck?
Labor and the structure under the boards. Modernize puts labor at 50 to 60 percent of a deck's total cost, and much of that time goes into footings, posts, beams and joists that nobody sees. After that, the decking material and the railing are the biggest line items: composite boards and aluminum or cable railing cost several times more per foot than pressure-treated wood.
How deep do deck footings have to be in Fort Collins?
At least 30 inches for an attached deck and 12 for a freestanding one, per the City's deck guide (revised June 24, 2026). Width matters as much: the City's chart, at 1,500 psf soil, sizes each round pier by the deck area its post carries, from 12 inches across at 20 square feet to 16 at 40, 22 at 80 and 31 at 160.
Is composite or wood better for a deck in Northern Colorado?
Composite usually holds up better here, and wood costs less up front. Fort Collins sits at about 5,000 feet with strong sun, dry air and freeze-thaw winters, which dry out and check unsealed wood; cedar and pressure-treated decks need sealing every year or two. Capped composite skips the sealing and carries 25 to 50 year limited warranties from Trex, but its boards cost roughly twice what pressure-treated lumber does (Modernize) and it runs hot in direct sun.
When is the best time to plan a deck in Fort Collins?
Plan in winter, build in spring through fall. Interest in deck builders across the Denver market peaks in August, and in covered patios in May, so spring calendars fill first. Design, the City's plan review and HOA approval can all happen over the winter, and footings can be dug whenever the ground isn't frozen.
