I live near Super King Market on Glenoaks, and I recently had Drip Too Hard Plumbing out for a drain cleaning. I’m really glad I called them. The drain had been backing up and draining slowly, and they were able to clear it out quickly without any mess. They showed up on time, explained what was causing the issue, and made sure everything was flowing properly before leaving. The whole process was smooth, professional, and stress-free. You can tell they actually care about doing the job right, not just rushing through it. If you’re in the Glenoaks area and need a reliable plumber for drain cleaning, I’d definitely recommend Drip Too Hard Plumbing. I’ll be calling them again if anything else comes up.

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!
