How do I know if my yard has a drainage problem that needs professional attention?

Common signs include water pooling near your foundation after rain or snowmelt, soggy patches in your lawn that stay wet for days, visible erosion channels on slopes, and brown or dying plants in areas that seem overwatered. In Northern Colorado, clay-heavy soil makes these issues more likely because the ground holds water rather than absorbing it. If you notice any of these symptoms, a site assessment can identify the source and determine whether grading corrections, a channel system, or soil amendment is the right fix.

What drainage methods does AGT use for residential properties?

AGT's approach starts with a full site discovery that includes soil structure analysis, utility locates, and a review of your property's existing grade. From there, the team designs a solution using laser-grading equipment calibrated to within 0.25 in. to establish precise slopes that direct water away from structures. Depending on the site, this may include surface grading corrections, retaining walls built from boulder, block, or stone to stabilize slopes, and soil amendment with compost and expanded shale to improve absorption. Every project is documented with CAD-based as-built plans.

Why does Colorado's climate make drainage especially important for homeowners?

The Front Range experiences 70 to 90 freeze-thaw cycles per year. When water sits in clay soil near a foundation or under a hardscape, it expands as it freezes and contracts as it thaws, gradually shifting and cracking structures. High-altitude UV exposure also accelerates material degradation when surfaces are repeatedly stressed by water and temperature swings. Proper drainage removes water from these vulnerable areas before the freeze-thaw cycle can act on it, significantly lowering the long-term cost of maintaining your home and outdoor spaces.

Will AGT handle HOA or municipal permit requirements for my drainage project?

Yes. AGT manages HOA submittals and municipal permit requirements as part of the project process. The team is familiar with local water-use ordinances in Boulder, Longmont, Fort Collins, and surrounding communities, including requirements like Boulder 1041 and Fort Collins Water Wise. After installation, clients receive CAD-based as-built plans that document all drainage routes and grading details, which can be submitted to HOAs or municipalities as needed. This documentation also serves as a permanent reference for any future landscaping or construction work on the property.

Does a drainage installation come with a warranty?

Yes. AGT backs all drainage and hardscape installations with a 2-year warranty, which is double the standard one-year warranty common in the industry. This reflects the firm's confidence in its engineering approach and materials. Because AGT operates under a Design-Build-Maintain model, the same team that designs and installs your drainage system also maintains the surrounding landscape, so any performance issues are identified and addressed quickly. The $5 million general liability coverage carried by the company provides an additional layer of protection for homeowners throughout the project.

How much does residential drainage installation typically cost in Northern Colorado?

Project costs vary depending on the size of the area, the severity of the drainage issue, and the methods required to correct it. AGT offers transparent pricing and can provide specific estimates after a site assessment. For reference, foundation finish packages start around $8,000 to $10,000, while full-yard design and construction projects range from $25,000 to $40,000 or more depending on scope. Clients who bundle drainage work with other services such as irrigation or hardscape installation may qualify for a 10% full-service bundle discount.

Residential Drainage | Longmont, CA

Water pooling in your yard, eroding slopes, or waterlogged garden beds are more than a nuisance in Northern Colorado. Clay-heavy Front Range soils drain poorly, and with 70 to 90 freeze-thaw cycles each year, poorly managed water can cause serious foundation and hardscape damage. AGT Landscape & Design provides residential drainage solutions in Boulder, Longmont, and throughout the surrounding region, using laser-grading precision to within 0.25 in. to move water away from your home and protect your property for the long term.

Northern Colorado's native soil is dense, alkaline clay that holds water instead of absorbing it. When rain or snowmelt has nowhere to go, it pools against foundations, saturates plant roots, and carves erosion channels into slopes. High-altitude UV exposure and repeated freeze-thaw cycles then crack any hardscape sitting on that unstable, waterlogged base. AGT addresses these issues at the source, amending soil with compost, expanded shale, and mycorrhizal inoculants to improve drainage capacity, then engineering grading and channel solutions that redirect water before it can cause damage.

Every drainage project begins with a full site discovery, including sun angles, soil structure analysis, and utility locates. From there, AGT's team builds a landscape drainage design that accounts for your yard's specific grade, your home's foundation proximity, and any HOA or municipal requirements in your area. We use laser-grading equipment calibrated to within 0.25 in. to establish precise slopes that carry water away from structures and toward appropriate discharge points. Completed projects include delivery of CAD-based as-built plans showing all drainage routes, giving you a permanent record of the work and simplifying any future permit or HOA submissions.

A drainage solution is only as good as the materials and methods behind it. AGT installs water management systems using regionally appropriate materials that resist the cracking and shifting caused by Colorado's 70 to 90 annual freeze-thaw cycles. Our retaining walls, constructed from boulder, block, stone, or railroad tie, stabilize slopes and prevent erosion while integrating cleanly with the rest of your landscape. Because AGT operates under a Design-Build-Maintain model, the same team that engineers your drainage plan also installs it and monitors site performance over time. All drainage and hardscape installations are backed by a 2-year warranty, double the industry standard, giving you confidence that the work will perform season after season.

AGT Landscape & Design serves homeowners throughout Boulder, Larimer, and Weld Counties, including Boulder, Longmont, Erie, Lafayette, Louisville, Superior, Lyons, Loveland, Fort Collins, Windsor, Johnstown, Firestone, Niwot, and Broomfield. Our crews carry OSHA 10 cards and hold Colorado Pesticide-Applicator licensing. The company is owner-operated by Alex Tanner, based out of Longmont and Berthoud, meaning the team managing your drainage problem knows the local soil conditions, water ordinances, and HOA requirements firsthand. Whether you are dealing with a waterlogged backyard, an eroding hillside, or foundation water issues on a new build, AGT has the regional knowledge and technical tools to solve it correctly the first time.
