I made an appointment with Tim over the phone days in advance for his Leak Detection service. He did not show. Called him twice the same day and left voicemails. Have not heard from him. Bottom line : Disappointed

Top notch service! We called On the Spot because we were concerned about a possible hidden leak in between our bathroom walls. John came out that same day, was super informative and helpful. He did a thorough check (he even checked our outdoor crawl space in the dark!) and was able to determine that we likely did not have any kind of internal leak, however, he DID detect an external leak coming from the base of the bathtub spout. Neither my husband nor I knew it was leaking (it was a tiny leak). I am SO glad we called this company!! John was helpful, friendly, funny, and prompt in getting over to our house. I will definitely use their services again in the future if ever needed!

Tim came out and spent a good deal of time working to find our trouble spot. Since we are in a condo the problem was within the shared wall with a neighbor. He gave us a recommendation for a specialist for our specific problem. He couldn't have been more helpful. We sent him off with a bottle of wine for his efforts:-) I would recommend him to both friends and family.

I recently moved to Sacramento and encountered a leak on the side of my home. I had at least 2 additional services out to try and detect the leak and fix it. They were unsuccessful and a waste of money. Not wanting to give up, I contacted Jon at On the Spot. He was very courteous and professional. I immediately got the impression this guy knew his business. He instilled a sense of confidence that you want in somebody who is trying to solve a problem for you. Jon arrived at the schedued time and immediately got to work. Within 30 minutes he had resolved what the problem was and the leak was fixed. I woke up the next day and yep you guessed it no leak. Don't hesitate to call at On the Spot, I had heard that Jon was the best in the business and after watching him work you soon realize why!

My mother in law needed termite treatments in her home which necessitated drilling of the concrete slab foundation and patio. I called Tim of On the Spot Leak Detection for locating the water pipes in the slab to avoid drilling into them. Matt came out to do the locating and was friendly, thorough and professional. He marked the pipes with blue painter's tape. The termite work was completed successfully without damage to the pipes. The price for the locating was quite reasonable too. I highly recommend On the Spot Leak Detection.

I've worked with Tim many times over the past 10 years or so. My line of work has us drilling through concrete on a regular basis, so having a good utility detection company is worth every penny. He's literally never steered me wrong. Thanks Tim!

Thank God they have offices in Sacramento & East Bay. I lhave been using Jon/Inspector (Sacramento) for several years. Gives me a true picture of the underground plumbing situation instead being at the mercy of unscrupulous plumber (who always finds more work after they dig). Always made it a point to clearly define findings- very respectful never condescending - very responsive to following up to make sure Leak problem is found. Hard to find contractors like this.

I am so grateful to know about On the Spot leak detection. My plumbing company advised me before even they came out, I should contact Tim at On the Spot leak detection because he has special equipment that could identify the exact location of our problem. Tim was prompt, professional and personable. He not only diagnosed the problem with his underground camera, but he then made two additional trips to our home in Orinda (at no additional cost): once to work collaborate with the plumber from Lett's, and a third time with a smaller and more agile camera to assure that the sewer line was clear beyond the initial obstruction. Tim's skill and thoroughness is far above and beyond the level of service I've come to expect in recent years. I highly recommend this company.

We found out we had a leak when a neighbor walking by the house saw a stream running down the walk. We called, talked with Tim and Matt came out to find the leak. Once found, we worked with Lett's plumbing and had everything fixed quickly. Great teamwork, highly recommended!

Best guys and service. I called yesterday because our water bill had sky rocketed. Tim called me back, and we chatted. Such a sweet man, he listened to our situation with kindness, and offered advice. Since we felt that he had located the problem over the phone, he still offered to come out to our home for a courtesy check of the water meter at no charge.
It's rare to find a company that really wants to offer the best service, for your benefit instead of their own. You can tell by Tim's caring nature that he is a stand up guy. I would refer this company to anyone looking to locate a leak in their home!
