Flagstone Patio Installation, Built for the Mountains.
Hand-fitted Colorado Red flagstone patios, designed around your property's grade, sun exposure, and views — built to hold up to real mountain freeze-thaw cycles, not just a flat backyard.
A Patio That Belongs on the Mountain, Not Just in the Yard.
Most patio contractors are used to flat, easy lots. High-altitude Teller County properties are a different job entirely — thin topsoil, exposed granite, steep grade, and a freeze-thaw cycle that will crack a poorly-built patio within a couple winters.
We build every patio on a properly excavated and compacted base, sized to the site's drainage and frost conditions — not a shortcut base that looks fine the first summer and heaves the next spring.
Flagstone is hand-set and fitted piece by piece rather than laid to a generic pattern, so the finished patio reads as natural stone that belongs on your hillside, not a poured slab with rock glued on top.
Joints are finished with sand or polymeric jointing sand depending on the look and durability you want — we'll walk you through the tradeoffs on-site rather than picking for you.
Every patio is designed in context with the rest of your property: how it ties into a retaining wall, a set of stone steps, a fire pit, or a walkway back to the driveway, so the finished space feels like one project instead of a patch bolted onto the yard.
How a High Point Patio Gets Built.
Site Walk & Design
We walk the site, read the grade and drainage, and design the patio shape and stone layout around it.
Excavation & Base
Proper excavation and compacted base sized for mountain freeze-thaw — the part you never see, but the part that matters most.
Hand-Set Flagstone
Colorado Red flagstone is fitted piece by piece, with boulder or timber borders where the design calls for it.
Joint & Finish Work
Joints are finished with sand or polymeric sand, and the site is cleaned up before final walkthrough.
Frequently Asked Questions
How long does a flagstone patio take to install?
Most residential patios take anywhere from a few days to two weeks depending on size, site access, and grade — we'll give you a realistic timeline during your quote.
Do you use mortar or sand-set flagstone?
It depends on the application. Most patios are dry-laid over a compacted base with sand or polymeric jointing sand; we'll walk you through the right approach for your specific site.
Can you build a patio into a slope?
Yes — terracing a sloped patio into a hillside, often paired with a boulder retaining wall, is one of the most common projects we build in this area.
What about drainage under and around the patio?
Drainage is planned into the design from day one, not added as an afterthought — we grade and, where needed, run drain pipe to keep water moving away from the patio and your foundation.
