Recommended Customer Reviews

We have used Wallace plumbing several times over the last couple years. They have repaired our drain lines, clean out our drain lines and replaced our water heater. Mark, Jordan and Manny have always provided excellent service at a fair price! Very impressed with their work!

DO NOT USE this company. I purchase a new water heater from them at almost $4,000 and I still have no hot water - they do not guarantee their work .. they will not respond to my call to fix the issue.

thank you mark! you are my hero. came to our rescue on a sunday; quality work; we enjoyed meeting you today. would recommend with a five star rating; wish i could give a ten star rating.

Mark, Jordan and Manny are all awesome.
They shoe up and actually CARE about what is happening at your place.
Mark is a sweetheart and an excellent plumber. Thank you for getting us thru our remodel!

Mark and his team replaced my broken water heater in 1 day.
Professional, efficient, clean up and disposal of old water heater.
He did a great job and we are very pleased with the work he did.
Thank you Mark for being available on a Sunday and getting us hot water again. If I need plumbing work done again, I'll call Wallace Plumbing!!!

Can't say enough about the SERVICE, SPEED and QUALITY of work performed by Mark and his team at Wallace Plumbing! Our water heater had sprung a leak and left a large puddle of water in the garage. Called Wallace Plumbing and they showed up within a half hour! Replaced our old water heater same day and took away the old one. Taught us how to drain it once a year and showed us the ins and outs of maintenance. Same day and service with a smile. Would definitely use them again! Thanks Mark & team! 5+ stars!

Very Friendly
But call to fix leaking faucet
Came on time with helper after $350 bill left with faucet still leaking

Great service and communication. Fair pricing and very helpful and friendly.
I would highly recommend Jordan.

Wallace Plumbing did a great job replacing my old water heater in a painless (no pressure (pun intended)) and very timely manner (same day). Very professional work. I really appreciated their honesty in discussing options and their reasonable costs. I won't hesitate to call them for future plumbing needs.

We can not thank Wallace Plumbing enough for all of their hard work on our home. Started off with a small plumbing job and turned into a need for completely new water and sewer lines. These guys were so friendly and flexible during the whole process, even during these huge storms. The whole team at Wallace Plumbing, Jordan, Mark, Kyle, Allen.. and many others involved made this process that much easier. Special thank you to them all for being so warm and welcoming to our family. If you are looking for a local plumbing company to get any job done large or small, give these guys a call.
