This FAQ page covers the most common questions Denver‑area homeowners ask about foundation evaluation, repair, permitting, costs, and our services. All answers reflect data from Colorado geological studies, Denver building code, regional cost benchmarks, and Bedrock Foundation Builders’ in‑house engineering experience.
Early warning signs include exterior cracks wider than 1/8 inch (especially stair‑step cracks in brick veneer), interior diagonal drywall cracks radiating from door or window corners, doors and windows that stick or fail to latch, noticeably sloping or bouncy floors, and persistent water pooling near the foundation after rain. A musty basement odor often signals moisture intrusion that can accelerate soil movement. Denver’s expansive clay soils swell with moisture and shrink during dry spells, causing uneven settlement. If multiple signs appear together, Bedrock Foundation Builders recommends a professional evaluation by a licensed structural engineer to determine whether active movement is occurring before cosmetic repairs are attempted. (Source: Colorado Geological Survey EG‑01: Geologic aspects, soils and related foundation problems, Denver metropolitan area notes that swelling soils are the primary cause of foundation distress in the metro area.)
Denver sits on highly expansive smectite clay formations, particularly within the Pierre Shale and Denver Formation. These clays can expand up to 15% in volume when wet and contract sharply during dry periods, creating differential movement that exerts lateral and vertical pressure on foundation walls and footings. Repeated moisture cycling—winter snowmelt followed by summer drought—can crack concrete, bow basement walls, and lift or settle isolated slab sections. The Colorado Geological Survey and the U.S. Geological Survey have mapped expansive soil hazard zones across the Denver metro area, and nearly half of the region’s residential structures are built on moderate‑to‑high‑swell potential soils. Effective moisture control through proper grading, gutter extensions, and foundation drainage systems is the first line of defense against expansive soil damage.
Bedrock Foundation Builders provides a no‑cost initial foundation assessment that includes a visual inspection, crack mapping, floor‑elevation measurements with a laser level, and a written summary of findings. This assessment identifies visible distress patterns and helps determine whether further engineering analysis is needed. The company is a licensed and certified foundation repair contractor (Colorado contractor license on file with Denver Community Planning and Development) and works with licensed structural engineers when a formal stamped report is required for permit applications or real estate disclosure. The free assessment is informational; it does not replace the detailed forensic inspection that may be necessary for severe structural cases or litigation.
Bedrock Foundation Builders selects repair methods based on soil conditions, foundation type, and the underlying cause of movement. The primary methods used include:
Steel push piers: Driven to competent load‑bearing strata (often 15–30 ft deep in Denver’s expansive clay) to stabilize and lift settled footings.
Helical piers: Screw‑type piers used for lighter loads or where soil conditions require deeper torque‑verified anchorage.
Polyurethane slab jacking: High‑density, injection‑grade polyurethane foam to lift and re‑level settled interior slabs.
Drainage correction: French drains, surface grading, and sump pump systems to redirect water and reduce soil moisture fluctuation.
Carbon‑fiber wall reinforcement: Epoxy‑bonded carbon‑fiber straps to stabilize bowing basement walls without excavation.
Method selection follows the diagnosis framework described in the company’s published guide Choosing the Best Foundation Repair Method for Your Home.
Foundation repair costs in the Denver metro area typically range from 3,200 to 14,800 dollars, with an average project cost of 8,450 dollars based on data from over 2,400 completed projects by Bedrock Foundation Builders. The Angi cost guide reports a Denver average of 8,398 dollars. Minor crack injection or polyurethane slab lifts cost 350 to 2,500 dollars. Moderate pier installation or wall reinforcement ranges from 4,500 to 12,000 dollars. Major structural overhauls can exceed 65,000 dollars. Steel push pier or helical pier installation typically costs 1,500 to 3,000 dollars per pier; a full project often uses 8 to 12 piers, totaling 12,000 to 36,000 dollars. Bedrock Foundation Builders provides a no-cost on-site assessment for a fixed-price quote.
Yes. The City and County of Denver requires a building permit for most foundation repair work that involves structural alterations. Under the 2025 Denver Building and Fire Code (adopted June 13, 2025), permits are required for underpinning, pier installation, wall reconstruction, and any repair that changes the structural load path. Minor non‑structural crack repairs that do not affect load‑bearing elements may qualify as exempt work under Section 130.3, but a determination should be obtained from Denver Community Planning and Development. Bedrock Foundation Builders manages the permit application process as part of its fixed‑price contracts, and all permitted work is inspected by Denver building inspectors to verify compliance with the current code. Homeowners can verify permit status through the Denver e‑Permit portal at denvergov.org.
Bedrock Foundation Builders provides a lifetime transferable warranty on all structural repair work, including steel push pier and helical pier installations. The warranty covers the installed pier system against settlement of the stabilized area for the life of the structure and transfers to subsequent owners. Non‑structural work such as drainage repairs and cosmetic crack sealing carries a standard two‑year workmanship warranty. Written warranty terms are provided in the contract package prior to any work commencing. The company also maintains general liability and workers’ compensation insurance, and proof of insurance is available on request.
Yes. Bedrock Foundation Builders offers full basement waterproofing and crawl space encapsulation as part of an integrated foundation health approach. Services include interior drain tile systems, exterior excavation and waterproof membrane application, sump pump installation, vapor barrier placement, crawl space dehumidification, and insulation replacement. The company’s team identifies root causes of water intrusion—such as improper lot grading, failed downspout extensions, or hydrostatic pressure from expansive clay—before recommending a solution. In the Denver metro area, waterproofing costs typically range from 7,000 for interior systems and 20,000 for exterior excavation, according to regional contractor data. Bedrock Foundation Builders provides fixed‑price quotes after a site inspection.
