Excellent service! My youngest accidentally flushed a toy down my toilet causing the water to drain slowly every time it was flushed. Jonathan was very professional and knowledgeable. He assessed the situation, explained the process clearly, and got right to work. He was able to remove the toy without any issues and was careful to keep the area clean on top of being very detail oriented. He went above and beyond and also checked the water pressure and made sure everything was working perfectly before he left. I highly recommend this company for any plumbing needs. I know who I will be calling in the future if needed again ! Thank you so much Jonathan you were amazing!
Top Plumbing Issues in Monrovia
These issues come up again and again. We're ready for them in Monrovia.
Galvanized pipes corroding and restricting flow
Learn more
Many of Monrovia's 1950s-1970s ranch and craftsman homes still have original galvanized pipes that are now severely corroded. The moderately hard water from Golden State Water Company accelerates this corrosion, leading to restricted water flow and rusty water.
Tree root intrusion in sewer lines
Learn more
Monrovia's mature oak and pepper trees, especially in established neighborhoods like Old Town and Library District, send roots into aging cast iron and clay sewer lines. These roots cause recurring backups and require professional cleaning or line replacement.
Water heater making popping or rumbling noises
Learn more
Hard water minerals from Monrovia's groundwater supply create heavy sediment buildup in water heater tanks. This sediment causes popping and rumbling sounds as water heats, and significantly reduces efficiency and lifespan of the unit.
Slab leak causing foundation concerns
Learn more
Many of Monrovia's ranch-style homes from the 1950s-1970s were built on concrete slabs with embedded copper water lines. Age and ground movement near the foothills cause these lines to develop leaks that can damage foundations and flooring.
