Plumbing reviews in Grand Terrace, California

It was great

Great help!

Please call your orders ahead of time.

They really try to help but, a lot of times they don't have what we need for plumbing.....

Great customer service, very helpful as well..

Great spot for specialty items and valves I definitely recommend them

Great customer service with outstanding knowledge. They have most anything you could imagine for plumbing.

I had a great experience. The customer service is awesome. Ill go back any time. Very fast service i was in n out..

This place is awesome. Always have what I need. Ask for rey and he hook you up. Easy to talk to and will figure everything out that I need all in one trip.

As a service and repair plumber for 30 years and a new construction commercial plumber for 6 years, I can say hands down the best supply house in the IE. Don't waste your money or time going anywhere else.

These guys are cool. They know their stuff and took time to explain in detail what I needed to do the job. You simply can't get this kind of help at Home Depot. Highly recommend.

Awesome knowledge and service

Had the whole thermopile assembly go out on our AO Smith water heater on a Friday night. No luck or knowledge at home Depot or Lowe's. Finally gave a call to Winnelson. They ask for the serial number, verify the correct part, had it sitting on their shelf and was open on Saturday.

They have my repeat business from this point forward.

Winnelson plumbing supply is how I wish Ferguson plumbing supply was. Every time I call this place the guys know what they’re talking about, they are in a good mood, they provide me with helpful advice, all-around great experience. The only downside of this place is there aren’t more of them.

Had an awesome experience here! Bryan went above and beyond to help me out. I highly recommend this establishment, looking forward to doing future business with them!!!
