Does your hot water fluctuate between scorching and lukewarm? This inconsistency could mean your hot water heater is failing to meet your household’s demands.
If you’re constantly calling for hot water heater repairs, it may be more cost-effective to invest in a replacement.
Most hot water heaters last 8-12 years. If your unit is older, replacing it with a modern, energy-efficient model can save you money in the long run.
Rusty water is often a sign of corrosion inside the tank, which can lead to leaks and reduced performance.
A leaking hot water heater tank is a clear indication that it’s time for a replacement.
Older hot water heaters are less energy-efficient, leading to increased utility bills. Upgrading to an energy-efficient model can lower your monthly costs.
Selecting the right water heater is crucial for ensuring a consistent supply of hot water and optimizing energy efficiency. Here are some key factors to consider:
Decide between natural gas, propane, or electricity. Each fuel type has its advantages. Natural gas water heaters are typically more energy-efficient and cost-effective, while electric water heaters are easier to install and maintain.
Assess your household’s hot water needs. Larger families may require a bigger hot water tank or a tankless water heater system to ensure a steady supply of hot water.
Look for energy-efficient water heaters with high Energy Star ratings. An energy-efficient water heater can help you save money on your energy bills and reduce your environmental impact.
Consider the available space for installation. Tankless water heaters are compact and can be installed in smaller spaces, while traditional tank water heaters require more room.
Determine your budget for the water heater and installation costs. While tankless water heaters may have a higher upfront cost, they offer long-term savings on energy bills.
We safely and efficiently remove your old water heater, ensuring minimal disruption to your home.
Regular maintenance is essential to extend the lifespan of your water heater and prevent costly repairs. Here are some tips to keep your water heater running efficiently:

Had a valve replaced and the price seemed higher than it should have been. When the plumber left, there were metal shards all over the bathroom that I had to... read more clean up. Just my experience. Update: Environmental Plumbing reached out to me and offered me a 15% refund because of my experience, and suggested that I update my review.

The technician you sent (Greg) was very efficient. He was a polite young person too. He did a tidy job. Please convey my appreciation to him. Michio
I had Lance help me out with an issue I was dealing with, and I couldn’t be happier with the experience. From the start, he was professional, clear, and took... read more the time to actually explain what was going on instead of just rushing through it!!! He walked me through the problem, pointed out what was causing it, and made sure I understood the options before moving forward. Once he got to work, you could tell he knew exactly what he was doing. Everything was handled efficiently, cleanly, and with a lot of attention to detail. What I appreciated most was that he didn’t cut corners. He made sure everything was properly fixed and double checked before wrapping up. It gave me a lot of confidence that the issue was fully taken care of and not just a temporary fix. Really solid experience overall and I wouldn’t hesitate to call him again!
Liam was great and wonderful. Will définitively recommend! Nice guy, very friendly, hard worker! We loved him at our home. He should quikly be a manager! Thank you Liam for... read more your awesome job!
Nick showed up promptly to install our dishwasher. He was extremely professional and quickly recognized some issues we had with our sink plumbing. He fixed the issues to... read more our complete satisfaction and was honest to not charge us the entire fee for installing the dishwasher as it required electrical work he was not licensed to do. Nick did an excellent job cleaning up after the job. We were extremely happy with the service and will contact Nick for future needs.
This afternoon we discovered a waterfall of water in our finished basement… cascading from the ceiling and creating a wading pool on our floors. I called Environmental Plumbing and Lance... read more was knocking on our door 15 minutes later. Less than 1/2 an hour later Lance had located and repaired the leak for us! I can’t say enough good things about how fast Lance worked and how cheerful and informative he was about the whole process. I can definitely say that the one good thing to come out of today’s water leak disaster was the fact that we have now found an excellent plumbing service for all our future needs as well as a really great plumber that we will ask for on any future visits! Thanks Lance for making us feel a whole lot better about this mess and for saving our basement from further damage.
They were responsive, kept me appraised of when the tradesman would arrive and explored options with me to address timing concerns. Very happy with the service and would recommend.
Miguel arrived promptly at 8 a.m. and quickly identified the cause of the problem that was not allowing my toilet to flush properly. He had a replacement in his truck... read more and had the flush working properly in minutes. He explained the billing clearly before he left. I was completely satisfied with the service he provided.
I have been using Environmental Plumbing's services for just over a year, and am always a happy customer! Most recently, (after yet another back up in the basement) Lance discovered... read more that my sewer line was sloping significantly. This would have led to further backups and drainage issues if left unfixed. Last week, Eric and his crew assessed the situation, and performed a lateral sewer line replacement. The job was done quickly and efficiently. Eric, Max, and Alex were very kind, thorough, and adaptable! They even did a great job cleaning up, and tried to make the yard look as normal as possible again. Environmental Plumbing is always the first call I make when something goes wrong, and I will continue to recommend them to anyone who will listen!
Had a huge plumbing emergency and Lance showed up in less than an hour at 2am and got it sorted out ASAP!!! Great service, friendly demeanour, super competitive pricing aswell!
Environmental Plumbing (my understanding is that they are a sister company of John the Plumber) The plumbing work at my home was completed in September 2025. I waited to post this... read more review because further renovations were required, and the seriousness of the issues only became clear once other contractors began their work. When my contractor’s licensed plumber inspected the plumbing, multiple deficiencies were identified, including: the toilet flange was installed 1.5–2 inches too short and unlevel and washer/dryer hook ups were not installed correctly, my tub was cracked and it took months to obtain pictures, not to mention that the supervisor was dismissive and unresponsive. These are not minor oversights. They caused delays with my contractors and required additional assessment to determine how to correct them. Considering the premium price I was charged; this level of workmanship is unacceptable — particularly given the errors that needed to be fixed. For the sake of keeping this review short, I have left out several other details. I repeatedly requested full photo and video documentation of the work. After persistent follow-up over several months, I was provided only five images. For a job of this cost and scale, that lack of transparency is concerning — especially since I required documentation for insurance purposes to confirm that pipes were replaced and to proceed with ongoing work. To be fair, Gary in accounting was professional and followed up when he said he would. I also dealt with Kelly A. in client service, who made a genuine effort to address concerns and helped restore some faith in customer service. However, the combination of substandard installation, pricing, project delays, and limited documentation has left me extremely disappointed. Based on my experience, I would not recommend this company.
I requested a plumber to check a low water flow in one of my toilets. The plumber showed up with no tools, left the led of the toilet and flushed... read more it to confirm the low, and checked the toilet brand (Gerber). His analysis was "I am not sure why this is happening, May be because you gave a canadian model, you should have bought American Standards, it is the best." He said that he will give me a price for installing a new one that "might" solve the problem, this is not what I asked for!!!!!. At the end he brought up the only tool he had on him, his phone to charge ~$90 for 7 minutes of guessing!!! I would not recommend this company at all!!!! It's a big scam and they have no experience plumbers!!!! P.S. The house was built in 2019, so it's not that old. **update based on the business reply: hiding behind industry standard practices doesn't give you the coverage to show up at people's place, do nothing, and provide no answer then charge people for what you say travel, lack of expertise, and made up assessment that is not related to the problem. also as you value your technicians' time, you have to understand that my time is valuable as well. I had to be away from my work and waiting at home for a professional plumber to show up and help me with my problem. Regrettably, the problem has not been addressed and I wasted a day out of my vacation days because of you.
What an amazing experience we had today with Liam! He did such a fantastic and wonderful job replacing our huge kitchen sink and our old faucet , and also unclogging... read more the hardest clog I've ever seen in my entire life! He dbl checked everything for any leaks and patiently answered all my questions. Such an efficient, skilled, polite knowledgeable guy! Wowwww!! I recommend Liam and Environmental Plumbing for all your needs!! 5 ⭐️
