Real Proof That Smart Service Works

Once again a very pleasurable technician was here. He not only explained before what was needed to be done but after showing me what he did and why. I’m very pleased with this company! I appreciate knowing ahead of time who was coming and then followed up with a call telling me when he would arrive. Thank you!

I've called Intelligent Plumbing quite a few time over the last 8 years for any plumbing related issues I had around the house abd must say that every single time they have been honest, courteous, and professional. They came in, repaired what needed to be fixed, and made sure the work are was clean before leaving. I've had great interactions with the techs that came to repair the issues and I will continue to use their services for years to come.- Nyght O.

Edgar from Intelligent Service was the best plumber I've ever had. He was kind, courteous, and a great problem solver. As with most repair jobs, once you open that wall, a million unexpected things go wrong. Edgar solved every problem and did so in a way that kept the job from turning into a massive beast of torn out tile or cut-outs behind cabinets, blah blah blah. I would fully recommend Intelligent to anyone with an old home that perhaps was not updated correctly in the past- and needs a creative thinker to solve your weird plumbing problems.- Teegan N.
Also- the person who called me to schedule everything and check on times was very well spoken, kind, and competent- something I unfortunately have found lacking in many repair service companies of late. So kudos to the office side of this company as well! -

They informed us what they could do and what options were an available going forward to avoid further issues. They provided us with a reasonable rate after observing the type of problem and if we were okay with the plumber going ahead and fixing issue. He took his time and was pretty thorough.

Just had an auto-water shutoff (Flologic) installed by Johnny. He quoted a fair price and we were able to get the work scheduled a few days later. He was professional and courteous. Overall a great experience and would definitely recommend.- Ben H.

At 3:00 in the morning my sump pump inverter started kicking on continuously, and I called they had a 24-hour hotline available. I chose to wait until normal business hours to have somebody come out, and they came out within 2 hours of opening. My technician was knowledgeable, gave me great advice, found the problem instantly, and then replaced it within an hour.- T. Duncan
