Outdoor living with the grading and drainage to back it up.
A concrete patio is the piece of your yard you stop walking past and start living on. Done right, it gives you a flat, durable floor for the grill, the table, the fire pit, and the foot traffic in and out of the house. Done wrong, it pools water against your foundation, cracks across the middle, and tilts toward the back door the first time the ground moves. The difference is almost never the concrete itself. It is the grading, the base, and the jointing underneath that nobody sees once the pour is finished.
On the Front Range that prep carries extra weight. Our soils swell when they get wet and shrink when they dry, and the surface goes through dozens of freeze and thaw cycles every winter. A patio that was not graded to drain or built to flex with that movement will tell on itself within a few seasons. We pour patios that shed water away from the house, hold their finish through hail and hard sun, and stay flat and crack-controlled for the long haul.
We build for Boulder County soils and the colder northern winters so the concrete holds its shape and finish. For concrete patios, that local knowledge is exactly what protects your investment. We plan the base, drainage, reinforcement, and finish around the conditions on your Longmont property, not a generic detail.
We serve every part of Longmont and the surrounding area, including Prospect, Old Town, Southmoor Park, Renaissance. Wherever you are in Boulder County, the crew shows up with the same standard.
At roughly 4,979 feet, Longmont gets intense high-altitude sun and a freeze and thaw cycle that is hard on any concrete poured without care. For patios, that means air-entrained mixes, deliberate curing, control joints cut on time, and a base prepared for the expansive clay under your property. It is the difference between work that holds for decades and work that starts failing by the first or second spring.
A patio sits right against the house, which makes its slope the most important number on the whole job. We pour a slight, deliberate pitch away from the foundation, usually about a quarter inch of fall per foot, so rain and snowmelt run toward the yard instead of pooling at the wall. That matters more here than in a lot of places. Water that collects against the foundation soaks into expansive clay, the clay swells, and you have invited the exact soil movement that lifts and cracks slabs. We set the grade before a single yard of concrete shows up, tie it into how the rest of your yard drains, and check it again as we screed. Get the slope right and the patio protects the house instead of feeding water to it.
The flatness you walk on five years from now is decided before the pour. We strip the topsoil, bring in and compact a base that gives the slab firm, even support, and add reinforcement so the concrete works as one piece instead of independent chunks. Then we cut control joints on a planned spacing. Concrete shrinks as it cures, and it is going to crack somewhere. Control joints decide where, giving the slab a clean line to crack along below the surface instead of a jagged one across the top. On a patio we lay those joints out so they look intentional and line up with the shape of the pad, not like an afterthought. Compacted base, steel, and joints in the right places are why a patio stays flat through our wet springs and dry late summers.
Here is the straight version: every concrete patio develops some cracking over its life, and any contractor who promises you a slab that never cracks is selling you something. Concrete is strong in compression and weak in tension, so when it shrinks during curing and when the ground underneath shifts, hairline cracks can show up. The real job is controlling where they go and keeping them cosmetic instead of structural. We do that with a properly compacted base, reinforcement sized to the slab, control joints cut on the right spacing, and real curing so the concrete gains strength evenly. On our clay soils we also pay attention to drainage, because the patios that crack badly are almost always the ones holding water against an already moving slab. Build it that way and the cracks that do appear stay thin, stay in the joints, and stay out of your way.
A patio is where the finish does real work, not just decoration. A broom finish gives you reliable grip when the surface is wet or there is a skiff of snow, which is the safe default for most families. If you want it dressed up, we stamp patterns that read like stone or plank, mix integral color through the pour, or expose the aggregate for a natural, textured surface that hides dirt and grips underfoot. Smooth trowel works for a sleeker look, though we will talk through traction before going slick on an outdoor pad. Whatever finish you pick, sealing it helps the surface shrug off UV fading, splash, and the road salt that tracks in over winter. We match the texture to how you actually use the space, then seal it so it keeps looking right.
Every Longmont job starts with a free, written estimate and a structural engineer on staff for the work that needs one. Licensed, bonded, and insured, with finishes from a clean broom texture to stamped, colored, and sealed.
You always know what is happening and what it costs before we mix a single yard. Here is the path from first call to final walkthrough.
We visit the site, measure, check drainage and soil, and hand you a clear written quote. No charge, no pressure.
We set the grade, thickness, reinforcement, and finish. Structural work gets engineered and permitted.
Forms, rebar, and a clean pour. We screed, float, and finish to the texture you picked, then cut control joints.
You can walk it in 24 to 48 hours. We walk the job with you and explain how to care for it through the first winter.
