Epoxy & Polyurethane Injection Specialists
We seal and repair foundation cracks in Fort Collins homes with epoxy and polyurethane injection: fast, clean, and built to last.
If you've found a crack in your foundation wall, the first question is always the same: is it serious? Our inspection answers that directly, and if a repair is needed, we get to it fast. Most foundation crack injections are completed same-day, with no excavation and no torn-up landscaping. Whether the crack is a hairline shrinkage line or a wider structural split, we diagnose it honestly and repair it with the method built for that specific problem.
Every job starts with an in-person look at the crack, the surrounding wall, and any related signs inside the home (moisture, staining, or nearby drywall movement) before we recommend anything.
For cracks that need to be structurally bonded back together, we use a low-viscosity epoxy injected under pressure along the full depth of the crack.
For cracks where water intrusion is the main concern, we use a flexible polyurethane injection that creates a permanent, flexible water seal, even in cracks that move slightly with the seasons.
For cracks tied to a larger drainage or grading issue, we can pair interior injection with exterior waterproofing recommendations. This is especially relevant for homes on sloped lots or with grading that directs water toward the foundation, a common contributor to recurring cracks in older Fort Collins-area neighborhoods.
Not every crack needs the same fix. We identify which category yours falls into during the initial inspection, before recommending any repair.
Every foundation is different, and so is every crack. Length, depth, width, and cause all affect the right repair method and the price. Rather than guess at a number that doesn't apply to your situation, we give every homeowner a free, in-person quote before any work starts.

If a crack doesn't need injection, we'll say so. Every recommendation is based on what we actually find during the inspection.
Our repair methods are chosen with Front Range clay soil and freeze-thaw cycles in mind, the same conditions that caused the crack in the first place.
Every injection repair is backed by our workmanship warranty.
A cracked foundation shouldn't be a mystery.
An in-person evaluation of the crack and any related symptoms. No repair is recommended sight unseen.
A plain-language explanation of what's causing the crack and which injection method fits.
Full-depth epoxy or polyurethane injection, completed in most cases in a single visit.
Every completed repair is covered by our workmanship warranty.
Yes. Most foundation cracks, whether hairline shrinkage cracks or wider structural cracks, can be permanently sealed and stabilized using epoxy or polyurethane injection, without full excavation. The right method depends on whether the crack is structural, water-related, or both, which is exactly what our free inspection is for.
Width is one factor, but not the only one. As a general rule, cracks wider than about 1/4 inch, cracks that are actively growing, cracks with a diagonal or stair-step pattern, or cracks accompanied by doors and windows that no longer close properly all warrant a professional inspection.
Cost depends on the length, depth, and cause of the crack, along with which injection method it needs. Because every foundation and every crack is different, we give every homeowner a free, in-person quote rather than a generic number that may not apply to their situation.
Surface sealants like Flex Seal can temporarily slow a minor leak, but they don't bond a structural crack back together or create a permanent seal against water pressure from outside the wall. For a lasting fix, an injection repair performed from within the crack itself is the more reliable option.
