Downspout Installation & Repair in Clovis, NM

Downspouts in Clovis face dual challenges: persistent High Plains winds that stress mounting systems and poor-draining clay-loam soil that pools water near foundations. Both must be addressed for long-term performance.

Clay-Loam Soil Drainage

Much of Clovis sits on clay-loam soil that drains slowly. Unlike sandy soils that absorb water rapidly, our dense clay causes surface pooling. Water discharged near foundations accumulates rather than infiltrating, leading to hydrostatic pressure against basement walls or slab edges.

Over years, this causes foundation settling, cracking, and moisture intrusion. We see this frequently in homes with inadequate downspout extensions—an easily preventable problem. Proper extensions move water 5-10 feet from structures to areas where slow infiltration won't threaten foundations.

Wind-Secure Mounting Essential

Sustained 20-30 mph winds with frequent 50+ mph gusts create constant stress on downspout mounting straps. Standard installations use straps every 5-6 feet—inadequate for High Plains conditions. These loosen over time, allowing downspouts to pull away from buildings and eventually separate.

We use commercial-grade mounting straps every 3-4 feet secured with masonry anchors or structural fasteners. This prevents wind-induced movement and ensures long-term stability even during severe wind events.

Monsoon Flow Capacity

Standard 2x3-inch downspouts are undersized for Clovis's monsoon intensity. During peak July-September storms, a 1,500 square foot roof receiving one inch in an hour generates 900+ gallons—far exceeding 2x3 capacity.

This causes gutter overflow even when downspouts are clear. We recommend 3x4-inch downspouts for all Clovis installations. The 60% capacity increase handles even our most intense storms without overflow.

Proper downspout placement requires understanding Clovis's unique challenges:

Foundation Protection

Minimum 5-foot extensions in all cases, 10+ feet for properties with known drainage issues or basement/crawlspace concerns. Water must discharge to areas where slow infiltration in clay soil won't affect structures.

Wind-Secure Mounting

Commercial-grade straps every 3-4 feet (vs. standard 5-6 feet) secured with appropriate anchors. Prevents wind-induced movement and separation during High Plains wind events.

Underground Drainage

For properties with limited yard space or severe clay soil drainage problems, underground lines route water to street drainage, dry wells filled with gravel, or safe dispersal areas. This is the premium solution for problematic sites.

Monsoon Load Distribution

Large or complex roofs benefit from additional downspouts. Rather than overwhelming two downspouts with massive flow during intense monsoons, four or six distribute loads evenly and reduce overflow risk.
