"This was the only service that provided me with a price over the phone before they came out. All the other services wanted to charge me a fee to just come look at the downspout extension, so I had no idea what kind of charge to expect. Evan was great, showed up on time and kept in communication with me on his arrival time. only took about 20 minutes from start to finish. "

Hi. My name is Scott and I am the owner of Plumb-It Inc. I am a 6 year army infantry veteran and have been plumbing for 12 years now. We are a newer company with low overhead so we can provide you with the top notch service of a larger company without the high pricing. We are experienced with all facets of plumbing to include service, remodeling, and new construction, commercial and residential. Honesty, integrity, and respect are cornerstones of my life philosophy, and I employ these characteristics in my daily work and dealings with people

"Scott, was very knowledgeable and responsive. He showed up on time and explained clearly what the situation. I've used him 3 times now because I know he is reliable, fair and knowledgeable. 1st time I spoke with him on the phone he was very patient with me and walked me through the problem. As to why the Hot water had a weird smell. He spent close to 30 mins on the phone with me. I will also call Scott whenever I have any plumbing issues."

"Prime Baths is one of the most impressive companies my husband and I have had the privilege of working with. Kevin came out to give us a quote and we didn't feel rushed as we tried to agree on what we actually wanted. When it came time to decide how to pay, you can pay in full or finance. We gave a deposit and decided to pay in full at the end of the project, so the materials were ordered. Material arrived on time, we scheduled the installation, and we pulled the dream installation team of Bill and Lennon. These two were amazing, they took out the old tub/shower and had the new walk-in shower installed in day one. They were very professional, personable, and knew what they were doing. They were back on day two to install the floor, vanity, linen closet, mirror, and towel bars. We are absolutely thrilled with the end result. Both my husband and I would highly recommend this company if you were thinking about making a change in your bathroom(s). Added plus to all of this, they have a lifetime warranty on their products and workmanship!!!"
