We compared 18 foundation repair services in Denver on Google Maps · 5 listed · How we rank

A sloping floor or a stair-step crack can mean anything from a drainage fix to a structural repair, and foundation repair services in Denver are not one single trade. The businesses below hold more than 5,400 Google reviews between them, all rated 4.7 or higher, yet their reviews describe very different jobs: slab and driveway lifting at some, basement walls and crawl spaces at others.

Short answer: Groundworks Foundation Repair Denver has the largest review base, at 4.7 stars from more than 2,600 Google reviews, though its reviews mostly describe lifting garage, patio and driveway concrete. Liftech Concrete Stabilization Systems (4.9, more than 1,100 reviews) is a Lakewood concrete-leveling company that also lists foundation repair, and HomeStrong is rated 5.0 on more than 400 reviews, many about basements and crawl spaces. One Colorado Structural Repair reviewer said a competitor quoted about $20,000 to lift a balcony before CSR found no foundation problem.

Our take: A smart call for a second opinion on a quote that feels large, and its site lists wall bracing, anchors and helical piers. Fewer reviews than the top names, at more than 250.

What the scorecard shows

Every figure here comes from public Google data on the date shown. Rating is the live Google star average. Review volume is how many customers have rated each company, set against the others on the page. Confidence weighs the rating by that volume, and recency shows how lately people are still leaving reviews. No business can pay to change these numbers.

What does foundation repair cost around Denver?

Foundation prices swing with the repair method, the size of the area and whether water has to be dealt with at the same time. One Colorado Structural Repair reviewer said a competitor quoted about $20,000 to lift a balcony, before CSR found no foundation issue. That is a single story, not a typical price, so get a written scope from at least two companies.

Foundation help across the Denver area

These contractors work from Denver, Lakewood, Henderson and Englewood addresses. Colorado Structural Repair lists Denver among its service areas on its site. If you are searching for foundation repair near me, ask each company how soon an estimator can visit your address.

What to ask before approving foundation work

  • Is this a foundation problem, or is it concrete settling or drainage?
  • Who evaluates the home, and is an engineer involved?
  • What method will you use, such as lifting, piers or wall anchors, and why?
  • What does the warranty cover, and will it be in writing?
  • What happens to drywall, landscaping or flatwork around the repair?

Frequently asked questions

Do I need a foundation contractor or a concrete lifting company in Denver?

It depends on what is moving. The reviews of Groundworks, Liftech and Thrasher mostly describe slabs, patios, driveways and porches. Reviews of Colorado Structural Repair involve basement walls, and HomeStrong’s cover basements and crawl spaces. If a wall is bowing or a floor inside is sloping, start with a company whose work involves walls and footings.

Can a Denver foundation company tell me I don’t need a repair?

Some do. Two Colorado Structural Repair reviewers said the company told them no foundation work was needed, including one who had a competitor’s $20,000 balcony lift quote. A Groundworks reviewer likewise said the estimator recommended only what made sense. A free evaluation costs nothing and a second opinion is easy to get.

Do these Denver foundation contractors offer a warranty?

One Thrasher reviewer mentions a five-year warranty and said a driveway area was later repaired under it, and Liftech’s website says its work comes with a warranty. Terms differ, so ask each company for the length and what it covers, in writing, before you sign.

Which of these companies also handle basement waterproofing and crawl spaces?

HomeStrong’s website lists basement waterproofing, crawl space encapsulation and sump pumps, and its reviews describe crawl space jobs. Liftech’s website also lists basement and crawlspace waterproofing. Groundworks and Thrasher are listed on Google as waterproofing services, and Thrasher’s reviews mention French drains and downspouts.

Where to begin

For sunken concrete around the house, Liftech and Groundworks are sensible starting points. For basement walls or crawl spaces, call HomeStrong or Colorado Structural Repair, and get a written scope and warranty from whoever you pick.
