"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"I called based on an Angie's List review.  They showed up promptly and most importantly the problem was fixed.  We have toilets that flush to the rear (not the ground) and they can be very tricky.  The toilet was leaking, but these guys fixed it.  Pricing was fair for the job.

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"Outstanding! Nick and his crew completed a renovation of our master bathroom, which involved replacing everything except one light fixture. Our project included removing the huge Jacuzzi tub; moving the toilet and building a half-wall to separate it from the rest of the bathroom; re-doing the shower fixtures; replacing the vanity, sinks and counter; enlarging the shower area; adding new lighting; tiling the shower and floor; repairing drywall; and painting the entire bathroom. Nick recommended vendors who provided tile, custom vanity, granite, plumbing, and glass products for our bathroom. All coordinated their services well with Nick to ensure there were no delays. One reason we chose to work with Nick is because he does all of his own work and does not subcontract to others—thus controlling the quality of work. It was evident he takes quality work very seriously. For example, he carefully explained the steps he was taking to prevent leaks in the shower. He also provided sound recommendations based on his experience; for example, we were considering a door-less (open) shower, but he explained that some people later regretted this choice due to drafts. Nick was also very flexible and able to accommodate changes as our project progressed. Although we didn’t deviate significantly from the original plan, we did make a few smaller changes along the way, such as opting for tile rather than wood baseboards. Nick’s team used care each day to protect our stairs, carpet and the adjacent bedroom. And each day, he explained his progress and what they would be doing the following day. When not on site, he was responsive and easy to communicate with. Nick completed the project in just over two weeks and in line with the budget we discussed in our initial meeting. We are thrilled with our new master bath! We are considering several other future projects and hope that Nick will be available to work with us when we are ready to begin."
