Recommended Customer Reviews
We are so happy with Colorado Plumbing and Gas Lines. Everyone that works here is so nice and caring. The field guys worked so hard and did a great job cleaning up and making sure everything is done correctly and safe. You won't go wrong using them.
My sister-in-law has been working with Nick since he was a young boy going out on jobs with his father. She recommended I call him to replace the toilets in my home and he was amazing. Nick gave me and estimate and his work was fantastic. Now, he is the only plumber I trust. He is very busy, but will always try to help in any way he can. I highly recommend Nick Unger with Colorado Plumbing and Gas Lines!!
Katy S.Nick installed a new hot water heater for me and found a problem with the venting. Even though it wasn't technically part of the installation he spent a considerable amount of time explaining and fixing this problem for me - AT NO CHARGE. I highly recommend this company.
We smelled gas in our house at 9:30 at night. We had Excel out to shut off the gas and in the morning I called about 5 different companies before I found Colorado Plumbing and Gas. They fit us into their schedule that day and fixed both sources of leaks (one from the stove and a second major leak from the furnace). Very prompt and professional!
Jim installed a new gas line for our stove. He was expert and very fast! Highly recommend him and the company.
David W.First off Nick, Jim and Lilly are all fantastic. I will fully and wholly recommend Colorado Plumbing & Gas Lines for ANY of your plumbing or gas line needs. Lilly works at the office and sets up the appointments. She is so kind and friendly to deal with on the phone. We stumbled upon Colorado Plumbing & Gas Lines strictly by accident. Through an exterior sewer line warranty I called with concerns about my sewer lines slow draining. I set up an appointment with the warranty company who contracts with local plumbing companies to do warranty work for them. The warranty company set up a time to have my sewer line scoped with a camera. I already knew my cast iron sewer line had to be replaced inside the house and I had 5 bids from local companies and also some large ""chain"" companies for an estimate. I figured if I had problems outside the house could get fixed at same time as inside the house.
My bids all came in and ranged between 9-25k. While Nick came over to scope the line for the warranty company, I asked him to give me a bid for the inside the house work. I told him that I was waiting on some bids and he said that he would get me one too. Nick said that he'd be more than happy to talk to me AFTER the sticker shock from the competition wore off. The bid to replace all the above ground cast iron sewer and a large stretch of nearly 20' of under the concrete slab in my basement, add a gas line since we wanted a gas oven, add a drain for my washing machine and also add a drain for our dishwasher was under 8k.
What really got me was Nick had a wonderful personality. He said that we didn't need to do certain things and wasn't trying to upsale us. His honesty was refreshing. I made an appointment with Lilly to get Nick to come back and replace the sewer line. Unfortunately we ran into asbestos floor tiles sitting on top of the concrete we were going to have removed and also in the drywall. At that point we had to have that professionally abated and had to cancel our original appointment. I called Lilly and talked to her and she was completely understanding and fantastic to deal with. We called a couple of months later after the asbestos had been abated and rescheduled the sewer replacement.
Jim and Nick showed up and literally started tearing out the old sewer lines and replacing them. They made sure that we were able to have waste lines for our toilet shower and sinks at the end of each day since it's our only home and we were living in it during this week long process. Jim and Nick are absolutely awesome, with great personalities. They made the process tolerable and were so informative and friendly. They will stand behind their work too.
One final thing that impressed me was when the city inspector showed up and checked the plumbing, he said that they did nice work. He also was impressed with the fact they ""bonded"" the gas line, which the inspector said he doesn't see often and again mentioned he was impressed with the plumber.
If you need a sink replaced or your entire house or business plumbed, do yourself a favor and call Colorado Plumbing & Gas Lines, you WON'T be disappointed.
April U.Loved working with Colorado Plumbing and Gas Lines. We used them to install a gas line in our backyard before pouring concrete. They were very informative about how much things would cost and how much we could save ourselves if we dug the trenches ourselves. I loved working with Nick! So personable and informative! He's a good guy to know! I would use them again in a heartbeat and absolutely recommend them!
Justin R.After receiving a quote from another company to replace a small section of pipe that was causing a restriction and low water pressure in our home , we decided to get a second opinion and we are glad to have done so!! A++ for saving us time and money!! HONEST and AFFORDABLE
Laura H.Jim came out and got my fireplace gas log set connected to the natural gas line and installed an emergency shutoff. He did a great job and it was no problem for him (numerous other plumbers didn't know how to do it or ""weren't interested"" in the job). I highly recommend! Thanks Jim--will be loving this come winter!!!
Cortney D.We hired Colorado Plumbing and Gas to move a gas line on a home we are remodeling. Lilly was so friendly and helpful in scheduling our appointment and getting us what we need. Nick was not only personable, but knowledgable, informative, and up front with his costs and timeframe for completing the work. Both Nick & Lilly are always pleasant - even when I ask a million questions! (which is common since I know virtually nothing about plumbing) Nick even let us know we were missing a vent for our water heater, which he noticed while installing the new gas line. Their pricing though not necessarily the cheapest, is fair (we had received some seriously inflated quotes previously) and Nick gets the job done efficiently and you won't have to worry about it being done right.
We would definitely recommend/refer them to anyone needing a good, honest plumber! Nick and Lilly are the best!
