Had an amazing experience with GLP - and Marcus was amazing! I’m an agent up in the area and it’s so nice to have a thorough company who talks you through what they find, what their recommendations are and answers any questions you have (and is available afterwards if clients have questions!) Thanks Marcus!!

Grand Lake Plumbing effectively communicates on service availability schedules and ensures we know who to expect will arrive at the specified time. We've worked with the company for years and Sam Brown, the plumber who helped us today, was knowledgeable and explained what he was going to do and why. He is personable and gracious. We recommend Grand Lake Plumbing wholeheartedly.

It can be hard to find great service in mnt towns, and I have to say GL Plumbing & Heating is a rare and exceptional find. They were able to move my existing appointment to accommodate a furnace issue. Communicated effectively and often. Great automated system, plus the human element, winning team. Looking forward to a long term relationship with them. Thank you!!

Timely and very communicative. Inspection was thorough and he warned us of issues to come so we know to start setting money aside for when they are pressing. Excellent service!

Arrangements were made for tech to enter and work on water heater when we would not be there. We were kept informed throughout the process. They responded to our need the day after our call. We felt like, "This is a really good company to work with."

Thankfully GL got us in same day and communicated with us every step of the way. Sam was easy to work with, friendly with our dogs that were on the loose. You will definitely pay a premium but quick and friendly service can be hard to find these days.

We had a great experience with Grand Lake Plumbing. We had a less straightforward job for them to do involving redoing the pipes for four sinks — one of which was a kitchen sink with a garbage disposal. This work was done over two days because we were replacing our countertops. I appreciated that they assigned the same technician to the second day so that he already had context on our unique job. They were very diligent, took their time doing everything with high quality. They cared about the outcome of the job which with some plumbers, they’re in and out as fast as they can. We’ll definitely use them again.

I love Grand Lake Plumbing! Becky and Rebecca are super helpful on the scheduling side. It’s been so nice getting to know Des Oliver who came out as the plumber for my pipe job. I really appreciate how he is so amazing at his job - not only on the technical repair/ installation / problem solving side but also as a patient and consultative partner for home owners. Really impressed by his professionalism and ability to explain the problem / teach me about maintaining my home plumbing systems. Meticulous and tidy. I also really like that there is an effort to keep the same tech on the case from start to finish and look forward to working with Des on my next project in a couple weeks.
Update - another awesome job led by Des with support from Seth today on my hot water heater install. Great problem solving, communication, and experience as always!!

They do excellent work and stand behind their solutions. Proud to have them as an Authorized Crusader Water Dealer for Granby County.

Joe, with Grand Lake Plumbing, did a very thorough job helping us with a tricky furnace repair. He was very thoughtful and communicative through the process. I feel like we hit the jackpot with Joe. We know that everything was fixed and no shortcuts were taken in completing the job.

We had a Phyn smart water controller installed last week. This device allows us to both remotely shut off the water but the device also learns usage patterns and will automatically shut the water off if it senses a leak. Very valuable device for a second home and wish we would have installed it several years ago.
Grand Lake Plumbig (Des) did a great job with the install, which took a little more than an hour.
We use GLP for all of our plumbing and heating needs both large (full boiler replacement last year) to small (radiant heat leak) and once again we were very happy with the service. Easy to schedule, great communication and fair pricing.

We always have a good experience with GL Plumbing & Heating. My most recent experiences have been with Marcus, and he is professional, fair, patient with my many questions, and gets the work done and done well. Des was also onsite with Marcus recently for a quote and to help troubleshoot a solution on a project and he was also kind and helpful. Becky at the office is usually the person answering the phone and is probably hearing people at their most stressed out, and she is the best. I am always grateful for her assistance getting things sorted out!
Grand County is fortunate to have this company of experts (and overall genuinely nice folks!)
Updated 10/17/25 to add that working with Sam today on a maintenance project for our sewer line winterization went smoothly! He was straightforward with our options, provided helpful info on how to weigh those options, and I appreciated his patience and good humor this morning!

Sam and his crew came and replaced a kitchen facet and added a fresh water bib to fill our hot tub. Very knowledgeable and explained different options. Yes, it was expensive but the two man crew was here for almost 3 hours. Also I had a boiler/heat inspection done by another GL employee who explained things well and explained benefits of their service contact. Very happy with service from all three employees.

Des (the plumber) did a great job. He installed water cop and new kitchen faucet. There was some faulty plumbing by previous contractors before we bought our current house in Columbine that was repaired by Des. I would recommend Grand Lake Plumbing. All of their technicians have been great. I have been using them for my houses in Grand Lake since 2005 and I’ve always had good results

GL Plumbing was exceptional! Extremely communicative. Very clear in explaining what was going to happen and to set expectations. The guys who came out and did the work were friendly, efficient and did a superb job. I kept thinking how incredibly professional every aspect of their operation is. Would recommend them in a heartbeat.

Today Josh carried out a service call on our heating system. An excellent technician both in terms of knowledge, skill set and a great ability to communicate. Work was carried out and follow up information was sent within the hour! Highly recommend this company.
March 26, 2025. Full boiler installation, with controls and water treatment complete! I love the technicians (Barry) and the workmanship. Design and technical feedback was excellent. Only issue is being able to contact the office. Hold time can be 30 minutes. Even the Building Inspector was unable to contact them to schedule an inspection. Fortunately he was able to contact me directly. Inspection passed with no issues.
August 6, 2025. No issues with the recent boiler installation, it has been working perfectly. I noticed an issue use with our water pressure over the last few days and contacted GLPH. Rebecca called me back within an hour and scheduled me for the next day (today) 👍. Des arrived promptly and quickly diagnosed the issue with a failure on the main well expansion tank. Upfront pricing was provided and Marcus collected the part from the shop. Both guys stayed late to get the install finished so we had water this evening. Thank you to the whole team!

All of our under-ground sewer line drainage system from under our garage and lower bathroom concrete slabs had to be removed and replaced all the way out to the road. Our house is 42 years old and the hardness of our water supply had corroded and even broke though the interior cast iron drains. The outside PVC sewer lateral also had a break and a couple of sags that necessitated replacement.
Grand Lake Plumbing did an exceptional job in communication and coordination of the project. There were four different contractors involved. They even met our needed “aggressive timeline.” I highly recommend using Grand Lake Plumbing for any of your plumbing needs.
I would like to give a special thank you and shout out to Travis Appelhans, John Schenk, Jon Chrysler, Anthony, Barry, and Danny. Their concern and skill for a job well done was simply extraordinary.!
The office staff of Becky and Melissa made communication and customer service a pleasant experience.
Again, for any and all your plumbing needs, Grand Lake Plumbing is definitely your default- choice!
Thank you to the entire staff of Grand Lake Plumbing for the successful completion of this complex project.

Grand Lake Plumbing, Heating and Sweetwater Pumps provided excellent service during my appointment. They came out and performed a well flow test for me.

Excellent customer service. Your receptionist was exceptional in keeping in touch and fitting us in next day. Our technician, Bayley, did an awesome job explaining the process and " after care".
Very professional, she was able to clear the clog rather quickly and followup testing to be sure all drains were flowing freely. The price was a bit high IMO, however the response time and professional work were awesome.
We contacted a number of local plumbers with little response or scheduling a week out (no toilet for a week was not acceptable).

Barry and Jayden were pleasant, friendly, and professional young men. They called in advance to let me know of their impending arrival. They were neat and clean throughout the process of removal and installation, and they even put down a large tarp as they wheeled units in and out of our dirty garage. They was patient with me as they answered all of my questions. I appreciated their willingness to share their knowledge. They went above and beyond during this project. We highly recommend Grand Lake Plumbing and Heating! They are the best!

John’s expertise as an engineer gave us the confidence in his understanding of our complex water, heating and ventilation issues. He spent considerable time with us to help us understand and make decisions regarding filtration, protection of our pipes and appliances, water storage, water heater and furnace. Exceptional customer service once again from Grand Lake Plumbing.

They did a great job troubleshooting my issue but were unable to correct it because it was electrical in nature. The tech (Aaron) was great but the diagnosis fee was incredibly high. I had to pay almost $300 for what amounted to a ten minute diagnosis and “sorry, we can’t fix it, call an electrician”. I still recommend these guys as they responded really quickly, but you will pay top dollar for their service
