"Fantastic! Very quick response on a Saturday. Tyrone was close by and quickly came over to evaluate whether or not this was a repair or a replacement for our Rheem tankless water heater. He was very kind and knowledgeable. Unfortunately, as I suspected, it was a replacement. Jeff the project called and we walked through our options and price with him. He was low pressure and very understanding. We decided after our research to schedule a replacement for Sunday morning. Les and Brandon arrived on time and were very nice and worked quickly. Overall it was a great experience and GREAT customer service! Les and Brandon were very helpful, knowledgeable and informative. HIGHLY RECOMMEND!!!"

"Andrew was very knowledgeable and thorough in explaining to us the differences and advantages about converting to a tankless water heater. The installation went smooth and as of now we are happy customers and would call them again if we needed."

"I called on Wednesday afternoon before thanksgiving day. We scheduled an appoint for Friday morning. The technician arrived at about 10:00 am. The technician was very polite, professional and cleaned up after himself. He had the problem identified and fixed within about 1/2 hour. After the repair was complete he gave us a couple of options as far as paying for the repair for that day or choosing a annual plan which included an annual tuneup for the air-conditioner and furnace. He was not high pressure just laid out what the offer was. We choose the later since we needed to have that none anyway next year. Very pleased with the service.

"As can happen, the project started out slow. Ryan was a little late the first day. But we discussed it, and he made up for it by getting right to work. He had a couple of guys with him, and they all worked very hard taking out the old deck, and getting ready to put the new one in it's place. During the project, we had a couple of hiccups (which I was quick to point out...lol). However, Ryan took care of them right away. And, as anyone who has ever done home repairs can tell you, sometimes unexpected things come up. Ryan went out of his way to take care of them as well. As for the new deck, I had a very detailed design that I wanted executed, and Ryan and his guys did a great job making my vision a reality. Bottom line, I am so pleased that I will keep him in mind for any other jobs that I may decide to do in the future."

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"I tried to fix my own sinks, but ended up having to turn off the water. I called Integregity Plumbing late Wednesday night. Steve was over first thing the next morning. He was prompt and friendly. Not only did he fix both sinks and restored my water, he brought both my bathroom sinks up to code. While he was working, I asked him several different questions about other problems I had in my house. He was very helpful. If I need any other help with plumbing problems, I will definitely call Steve again!

"I highly recommend Ultra Plumbing. This company is professional, efficient and solved my problem in a very timely fashion. Our laundry line backed up in the basement and it overflowed (water and grease everywhere). Ultra sent Shaun out to take care of it. Shaun didn't even have to pick up the job as he was just on call rather than on a shift, but he did anyway. He augured the drain and unclogged it and had the entire job wrapped up within an hour or two. We have not had the issue resurface since. The pricing was very fair as well."

"Rob is a consummate professional. He assisted us in discovering and dealing with damage from a leak in our basement wall. Rob made suggestions for the repair which was completed by our waterproofing company. He replaced the dry wall after cutting a one foot high section out of the perimeter of the room for the waterproofing work. Weeks later after the waterproofing was finished, he replaced the dry wall. We painted the walls and he came back to replace the baseboard trim. Rob always kept his appointments for work at our house. If he could not come at the appointed time, he called and set up another time. The work stretched over several months. We were delighted with the results. He did a wonderful job and we would not hesitate to call on him again."
