What a Bozeman winter does to a deck

Deck repair in Bozeman usually starts in late spring, when the snow finally melts off and shows what the winter did: boards cupped from months under snow, railings bent by snow sliding off a metal roof, and stairs that moved because their footings sat too shallow for the frost. We check the structure under the surface first, the ledger, joists, posts and footings, then quote either targeted repairs or a rebuild and explain the reason for each. The work is done by background-checked craftsmen and guaranteed in writing for one year. Call (800) 884-2639 for an estimate.

The Gallatin Valley is hard on outdoor wood from two directions. Deep frost and many freeze-thaw cycles heave anything set shallow, which is why stair pads and posts on grade drift out of line year after year. And at roughly 4,800 feet, the summer sun is intense, so stain on south- and west-facing decks breaks down much faster than the label suggests, leaving gray, checked boards that soak up snowmelt.

We repair, rebuild and build new decks in cedar, pressure-treated lumber and composite in Bozeman, from small ground-level decks off a newer home to raised decks with long stair runs and porches on older houses near downtown.

Before you call

Signs your deck needs attention

Soft or spongy boards

Press a screwdriver into the boards near the house and around the stairs. If it sinks in easily, the wood has started to rot. One or two soft boards can be replaced; soft boards everywhere usually mean the framing underneath is wet too.

A railing that moves

Push on the railing posts. Any give is a safety problem, and snow sliding off a roof or piled against the rail all winter puts real load on those posts. Loose posts often mean the bolts or the rim joist behind them have deteriorated.

Stairs pulling away

A gap opening between the top step and the deck, or stairs that tilt, almost always means the stair footing is too shallow and frost is lifting it each winter.

Rust and stains at the house

Rust streaks or dark stains on the siding below the deck point to water getting behind the ledger board, where the deck attaches to the house. Snowmelt sitting against that joint for months makes it worse.

Gray, checked or cupped boards

Boards that have lost their stain to the sun, split along the grain or curled at the edges have been through too many dry summers and frozen winters. They are a trip hazard and they hold water against the joists below.

Posts sitting on the ground

Posts set directly on the soil or on a thin pad, rather than on a proper footing, wick up moisture and move with the frost. You can often see the bottom of the post darkening or splitting.

Repair or rebuild: we show you the structure first

Surface boards are inexpensive to replace. Rotted joists, a ledger without flashing, or posts on failing footings are not, and covering them with new boards only hides the problem until it gets worse. Our craftsmen check the deck from underneath as well as from above, look at every post and the ledger connection, and show you what they find. If the framing is sound, we recommend repairing the boards, railings and stairs and keeping the structure. If it is not, we explain why a rebuild is the better spend, and we keep any framing that is still good.

02
On-site look at the structure
We check the boards, railings, stairs, joists, ledger, posts and footings, take measurements, and talk through what you want the deck to do for you.
03
A written estimate
You get a written estimate that separates required structural repairs from optional upgrades, such as new railings or composite boards, so you can decide what to do now and what can wait.
04
Permits and scheduling
Inside Bozeman city limits, building permits go through the City of Bozeman's building division. Outside city limits the rules differ by location, so we confirm what your project needs before work starts.

A background-checked craftsman does the work and cleans up. When the job is done, the workmanship is guaranteed in writing for one year from the invoice date.

Materials

Cedar, pressure-treated or composite

Pressure-treated lumber

The most common framing material and the lowest-cost decking. It holds up when it is kept sealed, but it checks and splits as it dries, and Bozeman's dry air and strong sun speed that up. Nearly every deck, whatever the boards are made of, is framed with treated lumber.

Cedar

Naturally resistant to rot and insects, lighter and better looking than treated boards, with a warm color that weathers to silver if left unstained. It costs more than treated lumber and still needs regular stain, more often on decks that face south or west.

Composite decking

Costs the most up front but does not rot, splinter or need staining, and it handles months under snow without cupping. It suits owners who do not want a staining job every few summers. Composite boards can often be installed on existing framing that is still sound.

Cost

What affects the cost of deck work

Repair versus rebuild

Replacing boards and railings on good framing costs a fraction of a rebuild. The condition of the structure underneath is the biggest single factor.

Size and height

Larger decks need more material, and raised decks need taller posts, larger footings and longer stairs, all of which add labor.

Decking and railing materials

Treated lumber is the least expensive, then cedar, then composite. Aluminum and metal baluster railings cost more than wood but stop needing paint.

Stairs and footings

Rebuilding stairs on footings deep enough to stay below the frost takes digging and concrete, and long stair runs on sloped lots take more of both.

Access, season and permits

Tight yards, steep grades, the short building season and any permit requirements all affect the schedule and the labor involved.

Permits for deck work

Building a new deck, and rebuilding much of an existing one, often requires a building permit, with inspections of the footings and framing. Inside Bozeman city limits, building permits go through the City of Bozeman's building division. Outside city limits the rules differ by location, so we confirm what your project needs before work starts.

Frequently asked questions

Should I repair my deck or replace it?

If the framing and footings are sound, repairing boards, railings and stairs is usually the better value. If the joists are rotting, the ledger has failed or the footings have heaved, a rebuild costs less over time. We check the structure and explain which applies to your deck.

Why are my deck stairs pulling away from the deck?

Usually because the stairs sit on a pad or footing that is too shallow, so frozen soil lifts them each winter. Rebuilding them on proper footings below the frost stops the movement.

Why does my deck stain wear out so fast?

Sun at Bozeman's altitude is intense, and south- and west-facing decks take the most of it. Add months of snow and many freeze-thaw cycles and stain breaks down faster than the can suggests. Cleaning and restaining on a shorter cycle, or switching to composite, are the usual answers.

Do I need a permit for a deck in Bozeman?

New decks and many rebuilds need one. Inside Bozeman city limits, building permits go through the City of Bozeman's building division. Outside city limits the rules differ by location, so we confirm what your project needs before work starts.

Do you build with composite decking?

Yes. We build with composite as well as cedar and pressure-treated lumber, and we can replace worn wood boards with composite on existing framing that is in good shape.

Can you replace just the railing?

Yes. Many older decks and porches have railings that are too low or have gaps that are too wide. We replace them with wood or aluminum railings at a safe height and spacing.

Snow slides off my roof onto the deck. What can be done?

Snow off a metal roof can bend railings and crack boards. We repair the damage, can reinforce posts and railings where the snow lands, and talk through layout changes if a rebuild is planned.

When is the best time to stain a deck in Bozeman?

Late spring to early fall, once the wood is dry and temperatures stay above the stain manufacturer's minimum. Staining before winter helps the wood shed snowmelt.

How long does deck work take?

Board and railing repairs often take a day or two. Rebuilds and new decks take longer and can depend on permit inspections. Your estimate includes an expected timeline.

Is deck work covered by your guarantee?

Yes. Our workmanship is guaranteed in writing for one year from the invoice date. If a defect in our work appears in that time, we repair it free of charge under the terms of your agreement.
