Gas Leak Search
One flat price to find the leak — no guessing, no hourly meter running.
When the utility company shuts off your gas, you need the leak found and fixed before it goes back on. Swan is a one-stop shop: we run the leak search, then make the repairs needed so your gas can be turned back on — no second company, no starting over.
*Cannot be combined with any other offer. The $250 covers the leak search only — repairs are not included and are quoted separately. Must mention when scheduling.
