Frequently Asked Questions

How do I know if I have a hidden leak? +
Common signs include unexplained increases in your water bill, damp spots on walls or ceilings, moldy odors, warm floors, or the sound of running water when fixtures aren’t in use. In Twin Cities homes, leaks are often hidden behind walls or under slabs, so they’re not always immediately visible.
Can you find leaks without cutting into walls or floors? +
In most cases, yes. We use advanced leak detection tools such as acoustic listening devices, thermal imaging, and moisture sensors to pinpoint the source accurately before making any openings. This helps minimize disruption and unnecessary damage.
Where do leaks most often occur in Minneapolis and St. Paul homes? +
We commonly find leaks in pipes behind walls and ceilings, under concrete slabs, at older plumbing joints, near water heaters, and at outdoor connections affected by seasonal temperature changes. Homes that have been remodeled in stages often have mixed piping materials, which can increase risk over time.
Is leak detection worth it compared to opening walls to look for the problem? +
Professional leak detection is often far less disruptive and more cost-effective than exploratory demolition. Accurately locating the leak first helps limit repairs to only what’s necessary and reduces the chance of repeated damage.
How long does leak detection and repair usually take? +
Many leak detection and repair jobs are completed in a single visit. Detection typically takes one to two hours, depending on complexity. Repair time varies based on location and severity, and we explain expectations up front.
Will you explain my repair options before starting work? +
Yes. Once the leak is located, we walk you through what we found, why it’s happening, and your repair options. Pricing is provided before work begins so you can make an informed decision without pressure.
Can leaks cause long-term damage if left unaddressed? +
Yes. Undetected leaks can lead to structural damage, mold growth, flooring and drywall damage, and higher utility costs. In Minnesota homes, freeze–thaw cycles can worsen small leaks over time, making early detection especially important.
Do you service leak detection throughout the Twin Cities? +
Yes. We provide leak detection and repair throughout Minneapolis, St. Paul, and surrounding Twin Cities communities, working in homes of all ages and layouts.
