Pool and Spa Leak Detection in Longmont
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak protects the pool shell and the soil around it.
Sewer Line Leak Detection in Longmont, CO
Sewer line leaks can cause foul odors, slow drains and potential health hazards. Our team uses camera inspections to visually identify breaks, cracks or blockages within your sewer lines.

We address sewer leaks in all types of piping materials common in Longmont homes, from PVC to cast iron.

Frequently Asked Questions About Leak Detection in Longmont
The cost of leak detection in Longmont can range from $250 to $800, depending on the complexity and location of the leak. Factors like slab leaks or those requiring special equipment may be at the higher end. We provide a detailed estimate after our initial assessment.
Most residential leak detection appointments take one to three hours. Larger homes, commercial buildings or multiple leaks can take longer. We give you an estimate when we schedule.
Older homes may have galvanized steel or polybutylene pipes, both known for higher leak rates due to corrosion or material breakdown. Copper pipes can develop pinhole leaks over time, while PVC and PEX are usually more reliable but can still leak at fittings or due to installation errors.
While you can check for obvious leaks like dripping faucets, hidden leaks require professional tools and expertise. DIY attempts can often misread the problem or cause further damage, especially with slab or gas leaks.
We use a range of professional tools including acoustic listening devices, thermal imaging cameras, specialized moisture meters, pressure testing equipment and tracer gas detectors for precise and non-invasive leak identification.
You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires specialized equipment. That is where professional detection saves time and money.
Many larger systems in Colorado draw on mountain snowmelt that runs fairly soft, while plains communities and groundwater sources often deliver harder water. Hard or aggressive water can cause pinhole corrosion in copper pipes over time. Slab foundations on shifting soils also put stress on pipes underneath the house, and high water pressure in some areas adds more stress.
Turn off all water in the house and watch the meter. If the leak indicator or dial moves, water is escaping somewhere. A sudden jump in your water bill is another clear sign.
