On Valentine's Day I discovered a big leak under my kitchen sink. With company coming the next day I knew I needed to get it repaired today! After calling 2 other plumbers unsuccessfully, Thomas came to my rescue that afternoon. Patrick quickly ascertained that I needed a new faucet. While I went to Home Depot to buy one he removed the leaking faucet and was ready to quickly install the new one. In spite of having to go to the store, the job only took one hour! Patrick was efficient, clean and confident, and he gave us the senior discount. I was both relieved and very pleased.

Awesome service! They were able to come out the next day. They gave us a time frame and called 30 minutes before their estimated arrival. Patrick arrived and had shoe protectors on ready to get the job done. We had a small leak on our master bathroom toilet. With the holidays, we just shut it off and then it sat for two months. So of course, our issue did not appear to be an issue when help finally arrived as the leaking could not be seen. Patrick went ahead and took everything apart to check and make sure there was no water damage underneath. He replaced the seal and put everything back together in a timely fashion. Highly recommend this company and love the fact we can support local businesses!

Great company! While they weren't able to solve our tricky problem, they were very responsive and waived our service fee due to this issue. Would recommend them!

Cody, the plumper from Thomas Plumbing was a credit to his profession and to his company!!! He was professional and he had great people skills. He explained every step of what he was doing. When I asked for his recommendations he gave them clearly, then left the decisions up to me. He worked with diligence and efficiency while maintaining a cheerful attitude. When he was finished he double checked his work. I was very grateful to have my plumbing problems fixed. The price was fair too.
The bonus for me was that I have used Thomas Plumbing a number of times and I have been very happy with them EVERY TIME!!!

I was very please with the promptness of Thomas Plumbing. Dave Thomas called back within the time he specified and had a technician out quickly. They addressed an issue under our house (crawl space) with the kitchen drainage pipe and were able to fix it without a problem and at a very reasonable cost. Cody was very straightforward, thorough and efficient.
I would highly recommend Thomas Plumbing and will not hesitate to call them again if any other plumbing issues arise in the future.

They've done great work on my plumbing and now on my
A/C unit. The young men that work there are always polite and their prices are very reasonable!

I can't begin to tell you how happy I was this morning when this Company ""squeezed me in""
in a very busy schedule since we're in the middle of a long, hot heat wave. My air conditioner went out suddenly, early afternoon yesterday. The company who put in my system, Valley Heating & Cooling could not get me in for three weeks, July 13! I never thought to get somebody local so I started making calls via Yelp. I made some 10 calls, most companies had the same 2-3 wk wait while anothers didn't answer their phone at all.
The HVAC person they hired recently is Gary, he was SO professional, polite, clean and
honest. He was in and out of my job in about one hour. The bill seemed very reasonable and fair.
I have use this company many times for plumbing services within the last 15 years, but I did not know they did heating and air-conditioning and it did not coming up in Yelp under A/C and heating.
I was referred to them by another company that did not do residential work named Duerr A/C and Heating. The gentleman there was very helpful, he told me how much he liked Dave Thomas, that he was always a fair, nice business owner. Thank goodness I called Duerr's to get Dave's name and number!
Thanks a million Dave & Gary. My house is now cooling off. I would recommend them if anybody needed air conditioning work.

Terrific service from a professional plumber service. Replaced water heater (~2015), and has continued to provide reliable and trustworthy followup. Recommend Thomas Plumbing for all service.

Everyone at Thomas Plumbing and Heating has been very kind and personable. I feel that the price and quality of my new furnace are excellent. My house feels much more evenly heated and comfortable with the Bryant unit they installed.
Thomas Garlick, the technician is very dedicated to his customers. He's a hard worker and great at his job.
I can't say enough about the fine service I have received.

Wow! If i could give a negative I would. Stay far away from this company. After 3 visits to install a reverse osmosis system and fix a tub that had only hot water, the tub was fixed, I have to call another plumber for the reverse osmosis system, and I had to fork over $600.00!! The kid they sent me didn't know what he was doing and even said that he looked up on utube how to fix the tub, and yet on the 3rd day his boss had to come with him to walk him through how to fix it. Never ever again. Beware! Update: So, after speaking with the owner, very nice man, the charge is reduce to a 1 1/2hr labor charge, very resonable. Family run business, son in law comes out to return my check, once again very freindly and apologetic, all I can really say is, I'm very happy that they show true concern for their clients, but they need to send experienced plumbers with the unexperienced ones so that this doesn't happen. Crazy, maybe, but I'm considering having them back for the reverse osmosis on the condition that they send an experienced plumber! Will return for another update.
