Recommended Customer Reviews

Another great recommendation! Mark came to my rescue and John checked a shower cartridge and replaced a handle and handle adapter that another plumber gave up on. Now my shower doesn't leak. Thanks for the great service.

Gerhard Weise Plumbing was recommended by my condo building's HOA president. At first, I was very pleased with them. They came out in a timely manner and completed the job well. However, I'm beginning to feel very frustrated with their administration. I received a bill and have called on 3 separate occasions to pay my bill. Each time I've left a message with an administrator and have not received a return call. Despite my efforts to pay, the company sent me a late bill notice. Is it my responsibility to track them down to pay a bill? I've done all I can do, and I feel that it's their responsibility to return my calls if they'd like to receive payment.

Highly recommended! We've been using Gerhard Weise Plumbing for years. They were originally recommended by our Realtor, who's also a neighborhood resident.
They've been quick when we've had semi-emergencies and have always done great work. When we have a routine task, like a new toilet to install, they're on time, courteous and if they can't come when they said they would because of another emergency someone always calls to let us know. We're never left hanging.
When we've had weird situations, like the sink in our lower level that drains upward (house built 1928), the plumbers collaborate and ask each other questions and work together to get things solved. They're also clear about explaining to us what the problem is and why it's challenging in a way we understand. Prices are reasonable.
Even our dogs love the Gerhard Weise plumbers!
I feel like we're always in good hands. Highly recommended!

The best plumbers in the area They do great work and they work quickly. The prices are very reasonable too. And when they are finished they clean up any mess.I have been really pleased with their service.We live in a senior condo and they come in here when someone needs them. Last Saturday evening was one of those times. The plumber had just left our building and was on his way home to his son's birthday party. Well he actually left and came right over to our condo did the work here and returned home late to his son's birthday party. We didn't want him to miss the party but he was only to glad to help us out in our time of need.Now that's saying something. Thanks for the great service!

I have used Gerhard plumbing a long time ago and I always liked them. They are very professional and do excellent work. I had to call them recently to fix a few things and they are efficient and good. I recommend Gerhard plumbing highly

I manage condo buildings in West LA and have had ample opportunity to work with both Gerhard Weise Plumbing and many other outfits that serve the area. I can say without question that I trust GWP to correctly diagnose the issue and not overcharge to fix it.

When a pipe inside the wall of my condo ruptured, we called Gerhard Weise Plumbing. They arrived quickly (late on Sunday afternoon). They SPEEDILY made permanent repairs. We did have to pay additional because it was an emergency and also an additional Sunday rate. The amount we paid was extremely fair even though there was extra cost for our circumstance. I will definitely call Gerhard Weise Plumbing the next time we need plumbing services. They are effective, efficient, and professional. Thanks so much for a JOB DONE WELL!

The plumber was good however it took them exactly 1 year to send me an invoice after calling them and asking them to send it for 3 months since I was never billed! I ended up calling another plumber for further work locally who was great, and actually gave me an invoice so I could pay them.

We got a note from the gas company during a building inspection that we couldn't have rope on our dryer ventilation pipe (put there by a previous owner) and needed to replace it with heat-resistant tape. The gas company advised us to call out a plumber for the fix. After a previous plumber I called completely balked at the job after he got here (even though I'd told his company exactly what I needed in advance over the phone), saying that he wasn't going to move the dryer to fix it--I called Gerhard Weise, who I am familiar with due to work they do for our HOA. The Gerhard Weise plumber threw away the rope and replaced it with heat-resistant tape in 10 minutes, all while only slighting moving the dryer to gain access. Thank you!

I have used this company for the last 7 yrs. I like that they are a family owned business. The customer service is always good, american speaking person on the phone who answers. Mark is honest and prices are fair.
