Had a pipe leak near the water main in yard and received many quotes for double and near triple what Knowles Plumbing actually charged. Richard was able to come out and fix the issue within my timeframe and had minimal downtime with no water to the house. Thanks, and much appreciated.

Knowles Pipeworks & Plumbing was amazing! They helped us get our bathroom sinks, vanity, and toilet all back up and running after a leak. Amazing quality work!

Highly recommend! We had a leaking shower valve, and they tracked down the proper parts and repaired the valve. Works great now! Even cleaned up to better than when they arrived to perform the repairs.
