Everything you need to know before building or replacing a deck in Colorado.
Materials, permits, climate, lifespan, ROI — the homeowner's guide.
A 30,000-foot view of what decking projects in Colorado actually involve.
Wood, composite, PVC, hardwood, aluminum.
Pressure-treated pine is the cheapest, lasts 15–20 years with maintenance. Cedar is mid-tier, beautiful, lasts 15–25 years stained. Composite (Trex, TimberTech) is premium, lasts 25–50 years with no staining. PVC (AZEK) is top-tier, completely synthetic, 50+ year life. Tropical hardwoods (Ipe) are gorgeous, expensive, and surprisingly demanding.
The right choice depends on budget, maintenance appetite, and how long you'll own the home.
What 'Colorado' adds to the wear equation.
High UV, hail (especially I-70 corridor), 40-degree daily temperature swings, freeze-thaw cycles, and dry winters that suck moisture out of wood — Colorado is harder on decks than most of the country.
A 25-year deck in Indiana might be a 15-year deck here if built from the same materials.
What requires one and what doesn't.
Any new deck or any structural repair requires a permit in every Front Range jurisdiction. Cosmetic refinishing and surface board replacement generally do not.
Permits exist primarily for life-safety inspections of ledger, footings, framing, and railings. Skipping them is the #1 issue we see in pre-sale inspections.
IRC 2018/2021 with local amendments.
Most Front Range cities adopt the IRC with their own amendments around snow load, wind, and footing depth. Jefferson, Denver, Boulder, Arapahoe, Douglas, and Adams all have slightly different rules.
We know each one and design accordingly.
Front Range loads are real loads.
Front Range ground snow load is typically 30 PSF, climbing to 50–70 PSF in the foothills. Wind loads matter for railings and pergolas. Mountain properties often have 80+ MPH design wind.
These aren't abstract numbers — they decide joist sizing, post sizing, footing depth, and railing attachment.
Where the water goes is the whole game.
Snowmelt off the deck, snowmelt off the roof onto the deck, summer storm runoff — all of it has to be managed. Proper grading under the deck, ledger flashing, post-cap flashing, and (on two-story decks) below-deck drainage all matter.
Water is the #1 killer of decks. Always.
What you'll actually do, by material.
Pressure-treated and cedar: strip and re-stain every 2–4 years. Composite: rinse with soap and water annually, deeper clean every couple years. PVC: just rinse. Hardwood: oil annually or let it silver.
Know what you're signing up for before you pick the material.
What you'll get back at resale.
Remodeling Magazine's Cost vs Value report consistently puts deck additions at 65–75% cost recovery in the Mountain region. Composite slightly outperforms wood at resale.
More importantly, decks dramatically improve time-to-sell — homes with quality outdoor living spaces close 9–15 days faster on average in metro Denver.

Answers before you ask.

How long should a Colorado deck last?
Properly built and maintained — composite 25–50 years, wood 15–25 years. Improperly built, half that.
Do you do free estimates?
Yes. Initial site visit, conversation, and basic quote are always free.
What's the wrong way to pick a contractor?
Lowest bid, no portfolio, no references, no permit history. That's also how you end up with a deck you'll rebuild in 8 years.
