About Alpha Leak Fix Pros

A DeKalb leak detection company that would rather charge you for an hour of diagnosis than a day of demolition.

We work out of 1600 E Lincoln Hwy Ste D, DeKalb, IL 60115, on the east side of the Lincoln Highway corridor. The business exists because of a gap we kept running into as plumbers: the standard way to deal with a hidden leak was to start opening things until water appeared. That works, eventually, and it is enormously expensive for the homeowner.

So we bought the equipment and learned to use it properly. Ground microphones, correlators, tracer gas, thermal imaging, line locators, sewer cameras. Then we built a rule around it that we have not broken: two independent methods have to agree on a location before anyone cuts anything.

What we do and don't do

Our work

  • Electronic leak detection on water, sewer, gas, pool and irrigation systems
  • Slab, under-slab and buried service line locating
  • Sewer camera inspection and defect locating
  • Leak repair, re-routes, sectional replacement and repiping
  • Water heaters, valves, fixtures, sillcocks and gas line work
  • Basement water diagnosis — plumbing versus groundwater
  • Insurance-ready documentation of losses

Not our work

  • Exterior foundation excavation and membrane waterproofing
  • Pool liner replacement and shell resurfacing
  • Fire suppression system alterations
  • Septic system installation and field replacement
  • Mould remediation and contents restoration

We refer these to people who do them well in DeKalb County rather than stretching into work that isn’t ours.

How we price

Detection is quoted before we start and credited toward the repair when we do the work. After-hours, weekend and holiday response carries a premium and you hear that number on the phone, not on the invoice. Repairs are quoted in writing before they begin. If the answer to your problem is a five-dollar toilet flapper, you pay the diagnostic and we go home — that outcome has generated more referrals for us than any job we talked someone into.

Ask for the number when you call. We would rather have an awkward conversation about price on the phone than an awkward one on your driveway.

Licensing, insurance and code

Plumbing is licensed work in Illinois and we are licensed to do it. We carry general liability and workers’ compensation coverage and can provide a certificate of insurance naming your entity before we start on a commercial property. Where a job requires a permit we pull it with the City of DeKalb’s Community Development Department at 164 East Lincoln Highway and schedule the inspection.

Work is carried out to the Illinois State Plumbing Code and DeKalb’s local amendments, including cross-connection control requirements for irrigation and other connections to the public water supply.

Working in this town

DeKalb has about 40,000 residents, a university that roughly doubles the daytime population in term, a housing stock spanning a century and a quarter, and a climate that puts every pipe in the city through a hard freeze annually. It produces a distinctive set of leak problems and we have spent years learning them.

Practically, that means we know which subdivisions have PEX crimp fittings and which blocks still have galvanized, that the busiest week for burst pipes is the one after a cold snap rather than during it, that a sump running in dry weather usually means an under-slab supply leak, and that a “foundation leak” in a twelve-year-old house off Dresser Road is very often a patio that changed the grade.
