Trusted across the San Marino area for honest pricing, clean work, and real warranties.
I have been using Drip Too Hard Plumbing (rebranded from DTH) for about a year. They were recommended by a good friend of mine who is a developer, and I have been ecstatic to find such a competent, ethical and reasonably priced plumbing service. Harry is very accommodating and has done a number of small plumbing jobs for me, including fixing work of previous plumbers (Installed new fixtures, fixed leaks from plumbing connections and garbage disposals and installed gas shut off valve). He has also done major construction for friends. I HIGHLY recommend him

Thank you so much for the kind words and continued trust over the past year. We're grateful for your friend's referral and even more grateful that you've chosen us for both the small fixes and larger projects. Harry and the team take pride in doing things the right way, and it means a lot to hear that it shows. We truly appreciate your recommendation and look forward to being your go-to plumbers whenever you need us.
We recently hired Drip Too Hard Plumbing when our old water heater went out, and I have to say they’re the best La Crescenta plumber we’ve ever worked with. From the first call, their team was professional, explained our options clearly, and gave us a fair estimate. We decided on a tankless water heater install, and the whole process was seamless—super clean work and they even took the time to walk us through how to use it. A few weeks later we had another issue with our drains, and they came out right away for a sewer line repair. The job was done quickly, with no surprises, and it’s been working perfectly since. If anyone is looking for a reliable plumber in La Crescenta, this is the company to call. Worth every penny for the peace of mind and quality of service.

Thank you for the amazing feedback! We’re so glad we could help with both your tankless water heater installation and your sewer line repair. Our goal is always to provide clear communication, fair pricing, and clean, reliable work that gives you peace of mind. Hearing that you consider us the best plumber in La Crescenta means the world to our team. We truly appreciate your trust and look forward to being here whenever you need us.
I found Drip Too Hard Plumbing while looking for a plumber in Burbank, and I’m so glad I did. From the moment I landed on their website, everything felt professional and easy to understand it’s rare to see a plumbing company with such a clean, modern site where you can actually book a free estimate in seconds. Their customer service was top tier. The team texted me before arriving, explained everything clearly, and didn’t pressure me into anything. They diagnosed my issue fast and gave me options with upfront pricing. What really stood out is that all their work is warranty-backed they don’t just fix and disappear. You can tell they care about doing things the right way. If you’re in Burbank and want a plumber that’s honest, responsive, and stands behind their work, Drip Too Hard Plumbing is the one to call. I wouldn’t go anywhere else.

Thanks so much for the awesome review! We’re proud to be your go-to Burbank plumber, and it means a lot that you noticed the effort we put into making everything easy — from the website booking to our free estimates and text updates. Our team always aims to treat every home like it’s our own, and we stand by every job with our DTHPromise warranty. If you ever need us again — whether it’s a quick leak fix or a late-night emergency — we’ve got you covered anywhere in Burbank, Toluca Lake, or North Hollywood. Appreciate you trusting Drip Too Hard Plumbing with your home!
San Marino Plumbing Problems We Solve
From older pipes to local water conditions, we've seen it all across San Marino.
Galvanized pipes corroding and restricting flow
Learn more
San Marino's pre-1960s estates often have original galvanized steel pipes that have corroded over decades. The moderately hard water accelerates this corrosion, leading to restricted flow and discolored water throughout these historic properties.
Water heater making popping or rumbling noises
Learn more
The mineral content in San Marino's water supply causes significant sediment buildup in water heaters, especially in older homes near Huntington Library and Lacy Park. This sediment creates popping sounds as the unit heats up and reduces efficiency over time.
Tree root intrusion in sewer lines
Learn more
San Marino's mature oak and pepper trees, particularly in established neighborhoods around Sierra Madre Boulevard, create persistent root intrusion problems in older sewer laterals. These roots seek moisture and can completely block clay and cast iron lines.
Low water pressure throughout the house
Learn more
Many San Marino homes experience declining water pressure due to mineral deposits accumulating in aging copper pipes and corroded galvanized systems. This is especially common in properties built during the post-war expansion of the 1940s-1950s.
