The patio calls we get from Broomfield usually start the same way. Water sat against the back door after a storm, or the grill wobbles where it never used to. A patio tilting toward the house isn't just an annoyance. It aims every rain and every snowmelt at your foundation, and in a town where wind has already dried and shrunk the clay beneath the slab, that water has a ready-made path down.
Why the back corner drops first
More often than not the sunken corner is the one under a downspout. Roof water concentrates there, softens the clay, and washes the base out from under the slab edge. Broomfield adds its own twist: summers here are wind-dried, so the clay farther under the patio shrinks at the same time the downspout corner erodes. The slab loses support from two directions at once, and it settles toward the heavier loss. We lift the slab, but we'll also tell you to extend that downspout well past the slab, because a lift over unsolved drainage is a repair on a timer.
A 1962 slab and a 2004 slab fail on different schedules
Broomfield Heights patios from the 60s have survived six decades of freeze-thaw. Most of the ones we see are still in one or two solid pieces, which is exactly what mudjacking wants. We bring the pieces back to a single plane and the old concrete keeps doing its job.
Out in Anthem and the other 2000s neighborhoods, patios are often stamped or colored, and they sit on younger fill that can still be consolidating. Those slabs settle early but evenly. We lift stamped and colored patios routinely; the 1-1/2" holes get patched flush, and after a season of weather and foot traffic most owners quit noticing them. That matters here, because replacing a stamped patio means matching a pattern and a dye lot that may not exist anymore.
The seasons that move a Broomfield patio
- Freeze-thaw shoulder seasons: water in the joints freezes, expands, and levers the slab edges a little more each cycle. Wind-driven drying keeps those joints open so more water gets in.
- Spring melt: the biggest single erosion event of the year at the downspout corner.
- High summer: shrinking clay quietly withdraws support while the patio looks fine.
People ask whether they should wait for warm weather to book. No need. The slurry cures fine in cold, and we lift patios all winter; the only days we skip are the rare stretches when the ground freezes too solid to drill a clean hole. A patio lifted in January drains correctly through the whole melt season instead of feeding it to your foundation.
What it costs to put the slab back
A patio lift costs about a fraction of what replacement does, quoted free and in person. The honest exception: if a patio has broken into many small pieces, we won't quote a lift. Small pieces rise unevenly and the joints reopen, so you'd be paying for a repair that can't last. We'd rather tell you to replace it than take the job. Slabs in one, two, or three big pieces almost always lift clean.
One visit, and your evening back
One visit covers a typical patio. Drill, pump the sandy loam slurry until the slab reaches grade, patch, sweep up. Trevor will tell you at the estimate when you can walk on it and set the furniture back. If the slab also pulled the back step out of line, say so when you call; fixing both in one visit is cheaper than two trips. While the truck is parked out front, it's also the moment to have us tap the front walk or the driveway apron, since the trip charge is already paid and small add-on lifts are easy to fold in. The full rundown lives on our patio leveling page.
Have Trevor take a look, free
Every quote starts with an in-person visit. Trevor measures the tilt, checks the drainage, and gives you a number on the spot. If the right answer is replacement, he'll say that too. Request a visit at our quote page or phone (303) 526-2222, and get the water moving away from your house before the next freeze.
