Loomiller is one of Longmont's oldest residential neighborhoods, occupying the blocks south and east of Old Town along Longs Peak Avenue and the surrounding streets. Development here began in the early 20th century and continued through the 1950s, producing a housing stock that includes some of the oldest plumbing in any residential Longmont neighborhood outside of Old Town proper.
The early-construction homes in Loomiller, built between 1910 and 1940, commonly retain original galvanized iron supply lines. In homes where the galvanized was never replaced, the pipe bore has narrowed through corrosion to a fraction of its original diameter, reducing water pressure at upper-floor fixtures and making the corroded sections vulnerable to joint failures under the pressure spikes that occur when water is shut off and restarted. A loud water hammer sound in an older Loomiller home is often the galvanized supply system expressing the combined effect of reduced bore and aging joints.
Sewer and Drain Risk in Loomiller
Loomiller's proximity to the St. Vrain Creek creates two specific plumbing risks. First, the water table in the blocks nearest the creek rises significantly during spring snowmelt, pressurizing basement walls and foundation floor joints from below. Second, the mature tree canopy throughout Loomiller, established over decades in front yards and parking strips, has extended root networks through cast iron sewer lateral joints throughout the neighborhood. Camera inspection of a Loomiller sewer lateral frequently reveals active root intrusion at multiple joint locations.
The most common services in Loomiller are whole-house repipe assessment for homes with original galvanized supply, sewer line camera inspection for root-compromised cast iron laterals, and basement leak detection during the spring snowmelt season. Foundation leak assessment is also common for the pre-war homes with rubble-stone or early poured concrete basement walls.
Loomiller Leak FAQ
My Loomiller home has very low water pressure upstairs. Is that a leak?
In a pre-1950 Loomiller home with original galvanized supply, low pressure at upper fixtures usually indicates mineral buildup narrowing the pipe bore rather than an active leak. A plumber can test pressure at the meter and at an upper-floor fixture to confirm how much pressure is being lost in the supply line. If the difference is large, repipe will restore pressure and eliminate future failure risk.
My Loomiller basement gets wet every spring. Is that fixable?
Seasonal hydrostatic intrusion near the St. Vrain Creek in Loomiller is addressable, but the approach depends on whether the water is entering through a wall crack, the floor joint, or a plumbing penetration. We identify the specific entry point before recommending any repair, so the intervention targets the actual cause rather than masking the symptom.
