Mid-century patios meet foothill weather
A big share of Golden's neighborhoods went up in the mid-century decades, and the back patios poured with those houses are now sixty-plus years old. They were honest pours. They've also spent all those years sitting on weathered Pierre Shale, under a sky that delivers the metro's first upslope snow and some of its fastest winter warm-ups. Concrete that old, on ground that active, rarely stays where the finishers left it.
The good part: a settled patio is one of the quickest things we fix. Trevor will tell you at the estimate when you can walk on the slab.
The shale swells, the wind takes the moisture back
Expansive clay moves a patio in two directions. Wet springs swell it and push slabs up against the house. Then Golden's wind goes to work. Chinooks and steady foothill gusts pull moisture out of open soil faster than almost anywhere in the metro, and the clay shrinks back from the slab edges. First a gap, then a lean, then a patio pitching toward your foundation.
That last stage is the one to take seriously. A back-sloping patio delivers every storm's runoff straight to your basement wall, and the repair bill for chronic foundation moisture makes a slab lift look like pocket change.
Why late fall keeps our phone ringing in Golden
Upslope storms drop snow on Golden patios early and often. A Chinook melts it in a day, the meltwater soaks into the clay, and the next clear night freezes it in place. Every one of those cycles works the slab a little. By the time the ground finally locks up for winter, the patio that was slightly off in September is holding water in November. We lift year-round, but the homeowners who call us before the deep freeze get the easy version of the job.
What the visit looks like on a Golden lot
Our 10-yard truck parks at the street or in the drive, and the portable pump travels to the backyard, which matters on hillside properties where nothing wheeled is getting behind the house. The crew drills 1-1/2" holes through the low sections of the patio, pumps the cement, water, and sandy loam soil slurry until the slab floats back to grade, and patches the holes before packing up. One visit, start to finish.
While we're there, we'll also point out what made the patio sink in the first place. More often than not in Golden it's water routing: a short downspout, a grade that funnels the hillside's runoff along the slab edge, a planting bed that holds moisture against one corner. Fixing that costs little and it's what makes the lift last.
What Golden patio leveling costs
A patio lift comes out to roughly a fraction of what a tear-out and re-pour costs, quoted free and in person. Stamped and colored patios lift the same way; we patch the 1-1/2" holes flush afterward. Things that move the price within the range:
- Slab size, since a bigger patio takes more slurry and more holes
- How far it has dropped, from a half inch to several inches
- Voids underneath, which we only fully know once the pump starts
- Access on sloped yards, common on Golden's hillside lots
When a new pour is the honest answer
Slabs in two or three large sections we can usually bring back to one plane. A patio that has broken into many small pieces is a different animal: the pieces rise unevenly and the joints spread. In that case we'll tell you to pour new, even though it means we don't get the job. We'd rather lose a lift than sell you a repair with a short life.
Get eyes on it before it gets worse
Estimates are free and always in person, because a patio can't be quoted from a photo. Trevor checks the drainage, taps out the voids, and gives you a written number on the spot. Call (303) 526-2222, or start with the online quote form and we'll set a time.
