My entire experience has been all positive! Jonathan in the sales room was so friendly, helpful, patient, and thorough. We also had them do the construction work on our house, and everything turned out great. Ray, the manager, very professional and communicative. Jake and Bobby had a great attitude and you could tell they’re passionate for the work. Highly recommend!!! Very grateful for their team. Even my shower tile installer said we chose a great plumber and appreciated the good work.

The parts/showroom department deserve a medal for the help today. I have been stranded looking for vintage plumbing parts for a week now. Johnathan (didnt catch spelling) knew exactly what I needed at a split second. I am so impressed, and so happy that a place like this still exists in my hometown.

Keep it up :)

We had a clog in our system from years of buildup and worried that we would have to renew our drain system before remodeling our kitchen. Chris at McGill came to our house, cleared the drain and then inspected the entire system with a camera. Luckily, it was just build up over 20 years and water is draining perfectly! He was knowledgeable, kind and efficient. Arrived on time, and did a great job! Highly recommend McGill Plumbing!! The pricing was fair, unlike other ripoff plumbers we have used in the past.

Tom and Johnny came today to level my toilet, remove old and install new bathroom faucet, and replace kitchen sink filter. They called before arrival, arrived within time stated, did all repairs for a reasonable price. Very pleased with their work!

Nichole and her team help solve a major water heater and plumbing problem that we had over the holidays in a rental condo. They got a team over quickly who got everything repaired and back working The same day. We will always use McGill for future plumbing needs. Thanks so much for getting it solved.
