Manny is truly outstanding! Tim and Tori have consistently provided excellent service for the past 8 years, taking care of three of our homes. We recently had two new installations done, and this time the company exceeded all expectations. Manny and Geo are incredibly knowledgeable, responsive, and thorough. They took the time to sit down with me and explain everything in detail.

From the way beginning, back in April, my wife and I saw 3 different companies to see what is the best fit for us. One was very confident and was trying very hard to sell us. The second person, she was a little more friendly but still didn't fit our request, third person was just all over the place, and finally 1st Choice came along. Tim, who was very knowledgeable, courteous, and friendly, told us everything

Manny came in ready to get my AC back up and working, he began by ensuring the component was in stock and available. When he showed up at the house he worked tirelessly and diligently despite the 106 deg heat. He completed the job perfectly ensuring the unit was cleaned and working properly. He checked the house inspecting the vents to ensure air was coming out at the right temperature.

Signs You May Have a Slab Leak

Slab leaks aren’t always obvious, but your home will usually give you clues. If you notice any of the following, call us right away:

Our Slab Leak Repair Services

When it comes to slab leak repair in Phoenix, AZ, we offer several approaches depending on the location and severity of the leak. Spot repair is the most direct option, as it allows us to access the damaged pipe and fix it at the source. For older or more deteriorated pipes, rerouting is often a better long-term solution, running a new line through the walls or ceiling to bypass the problem area entirely. In cases where the pipe system has seen significant wear, repipe and recoat options may also be on the table. We walk every homeowner through their options clearly so you can make the best decision for your home and budget.

Frequently Asked Questions

What causes slab leaks in Phoenix, AZ homes?

Phoenix’s extreme heat and shifting soil put constant stress on underground pipes, causing them to crack, corrode, or wear down over time. 

Most repairs are completed in one day, though more complex jobs involving rerouting or repiping may take longer, depending on the scope of work.

Coverage varies by policy. Many plans cover the cost of accessing and repairing the leak, but not always the pipe itself. We recommend checking with your insurance provider directly. 

Yes. Left untreated, water from a slab leak can erode the soil beneath your foundation, leading to settling, cracking, and costly structural damage.

If you suspect a leak but haven’t confirmed it yet, detection comes first. Once we locate the problem, we’ll recommend the appropriate repair approach based on our findings.
