Plumbing reviews in Denver, Colorado

The owner is very professional and personable. They pay close attention to detail and their work is something they take pride in and it clearly shows. I would recommend them 10 out of 10 times. They are a smaller local business which I love! I see a bright future ahead for them.

Danny and his team are easy to work with and great at what they do. They may not be the most cost effective option, but the quality they provide makes it more than worth it. Clear communication and expectations, followed up with great service. I have worked and seen the work of others, and will be calling One Line before anyone else in the future.

Highly recommend One Line Electric for any electrical needs. Danny, Aidan, and the rest of the team are fantastic at what they do. The team performed a thorough assessment of a fire-damaged property, as well as recommendations for everything needed to bring the system back to safe and normal operation.

One Line has outstanding service—punctual, professional, and honest. Their work was clean, efficient, and up to code. Highly recommend for any electrical needs in the Denver area. Dan and his team are top notch!

I wholeheartedly recommend One Line Electric Plumbing and HVAC. They delivered exceptional service, expertly handling my AC unit and wiring. The team arrived punctually and demonstrated remarkable professionalism and expertise. From beginning to end, I felt confident and well taken care of by their outstanding service.

I needed a Level 2 EV Charger installed in a way that would still allow me to use my welding machine at other times. They came up with a great solution! Clean installation, and both systems are working well.

I had the privilege to have One Line Electric set up our electrical outlet for our hot tub and not only was everyone I interacted with from the company, respecful, knowledgeable, professional. They also did the best job I could have asked for. I realize quickly that I was in good hands and will not hesitate to call them again if the need arises.

I was Superintendent sharing GC duties on a huge job in a very prominent neighborhood in Beaver Creek Colorado. We were short staffed and needed to meet our deadline. Danny and his crew were happy to help and made the long drive from Denver leaving family and friends behind to come and bail us out. Danny and his team were so professional. They were courteous, fast and did an amazing and professional job. The home they serviced was featured in an online magazine/video because it turned out so amazing. I would recommend One Line Electric for any and all jobs if you are looking for a clean, concise, and extremely thoughtful and professional outfit to reach all of your Electric, HVAC and Plumbing needs, and would give them 10 stars if it was available.

Danny and his team are absolutely fantastic! They are thorough, knowledgeable, and straightforward to the approach of the project at hand. Danny's professionalism and timely help is unmatched. I couldn't recommend One Line more!! Just do it already, you wont be disappointed!

An amazing plumbing, electrical, and HVAC company. The owner of the company is such a standup guy which made trusting him and his team with these projects an easy choice

We have used One Line Electric in the selling of our old home and the purchase of our new one, and both times they've been phenomenal to work with. The communication has always been professional and responses have been timely. Their customer service and quality of work is really unmatched. I'm so thankful to have been referred to them!

We had a great experience working with One Line Electric. They installed a new electric panel in our home and did a fantastic job—everything was done cleanly, professionally, and right on schedule. Super knowledgeable and honest throughout the whole process. Highly recommend!

Danny and Tommy were absolutely awesome at helping me out with plumbing issues. They scheduled the visit quickly since my sink was leaking pretty heavily. Tommy came out on time and fixed it without a problem and taught me why it was leaking and how to avoid the problem in the future. I also had him look at my other sink and he found an issue that I didn’t know about saving me a ton in repairs in the future! I highly recommend them and will be using them for the future. They were fair with their pricing, on time and great with communication, and just all around great people. It was the easiest time I’ve had getting something fixed in my house

Danny and One Line were very prompt, professional, and great to work with. I was very pleased with the work they have done and definitely will be using them in the future.

I’m a masonry contractor in Denver and I run into many clients asking if we know a good electrician. I have referred several of my clients to Danny at One Line Electric and every single one of them has thanked me. Danny is very responsive and knowledgeable. I highly recommend One Line Electrical whether it’s an older home, newer home, remodel, or new construction.

Tommy (plumber) and Alex (electrician) were amazing and super quick repairing my water heater. I appreciate they didnt push me to replace water heater and simply fixed the unit. I appreciate that. When it is time to replace my water heater, I will be using these guys. Thank you.

The company is absolutely amazing. The staff is amazing and they are always there for you and your needs. Highly recommend Callie for all your needs

Danny and all the professionals at One Line are impossible to beat. Professionalism, transparency, and an impeccable outcome can all be expected. Five stars and highly recommend!

I had the pleasure of hiring One Line for a project in my basement, and I couldn’t be happier with the results. They tackled a variety of tasks, including installing new lighting fixtures, upgrading the electrical panel, and ensuring everything was up to code. What impressed me most was how they handled the challenges of working in a tight space with outdated wiring, turning a tricky situation into a seamless success.
The team was exceptional from start to finish. They arrived on time, were incredibly courteous, and demonstrated a level of professionalism that put me at ease. They didn’t just get the job done—they took the time to explain everything to me, answering all my questions with patience and expertise. It’s clear they know their craft inside and out.
The quality of their work speaks for itself. The craftsmanship is top-notch, with every detail meticulously handled. My basement now feels safer, brighter, and more functional than ever before, thanks to their efforts.
I wholeheartedly give One line a 5-star rating and highly recommend them for any electrical work. They went above and beyond my expectations, and I’ll definitely be calling them again for future projects. If you’re looking for reliable, skilled electricians who truly care about their customers, look no further!

I made the mistake of trying to do electrical work on my own. Called ONE LINE ELECTRICAL LLC for help. They sent out Doug and he amazingly fixed my problems. Had a GFI that wasn’t getting power he found out the problem quickly and got it working..
super grateful for all the help! Will use them in the future for other electrical shortcomings. Thank you all it was pleasure working with you. Danny worked to quickly get me in when they are normally busy with other projects.
