Recommended Customer Reviews

Jon was prompt and courteous. His vast experience was evident as he diagnosed the leak issue/water pressure noise within minutes of arrival. His diagnosis saved me from a much more expensive visit from a plumbing company. This is exactly the kind of upfront and honest company I like to do business with. Kudos to you, Jon!

I didn't get to use On the Spot but wanted to commend Jon for calling me back while he was on vacation. He offered me great advice even though he didn't need to. Thanks.

Called John the day before Thanksgiving. Had no hot water at a rental. John came out at 530pm and diagnosed the problem. He was definitely Johnny On the Spot. Fair, professional, available, informative. I would definitely recommend for your plumbing needs!

John's communication was great. He showed up on time and did the job quickly and accurately. He was also more affordable than the company I was referred to. I'd definitely recommend him.

Great response very friendly he came to check where the leak was and I had my people fix it!
My kind of business!! Thank You!

We have used OTSLD many times and they are soooo good! Great service and John so helpful-never missed a beat and found leaks right away. def will use again

Jon was awesome. Answered on the first call and very responsive. Underground leak detection was well priced and quick! Would definitely use again... but hope not to need him

Out of the blue we found the carpet between the kitchen and living room getting lightly but consistently soaked from an unknown source. Since there was only one logical water line that could run under that spot I figured we must have a leak under the slab. I was cringing at the thought of both the expense of the repair and of having somebody jackhammering concrete in the middle of our living room.
I called several plumbing companies and it turns out most do not offer leak detection services, just leak repairs. Looking at the reviews here on Yelp I found On The Spot Leak Detection was getting excellent reviews. I called them up in the morning, and Jon told me he could be out that afternoon, and quoted a flat rate of $295.00 for the work. That was already $100 less than than some other services with ratings not as good on Yelp.
John arrived on time, and before bringing in any gear did a quick inspection of the problem area. He said something to the effect of ""Relax, this might not be as bad as you think."" He went into the kitchen, pulled the refrigerator away from the wall, and went around the back. A few seconds later he said, ""Good news, you don't have a leak under the slab. The connection hose to the ice maker has a slow leak at the shutoff behind the fridge and is leaking water down into the wall, which is soaking your carpet three feet away from underneath.""
Then, he said that since he didn't really have to do a regular leak inspection, would I be OK if he charged me $125.00 to cover his time to come out. I was so relived that I was NOT going to have a $2,000 plumbing repair expense and I was completely expecting to pay the $295.00 he had quoted, so my day just got better still. What great service and integrity.
Thank you Jon, I appreciate all you did.

We were not sure what was causing the leak so we called a plumbing company first. They referred us to On the Spot. Jon came out a couple of days later and immediately found out the cause. He gave us good advice and left without charging! He is friendly and we like him! We will definitely call him again in the future.

The city informed us we had a leak in our main water line, so we began our search based on Yelp's services. We wanted someone to detect our leak, not a plumber, after being gauged by a plumbing company who supplied a leak detection specialist. While Jon wasn't available immediately, he honored us for waiting with a lower price. He also provided a referral as well as comments that were helpful in narrowing the scope of the job we were facing. We're fortunate to have found him and will use him in the future because of his honesty, integrity, and skill set.
