"I had water damage to the ceiling of my garage. Vicente provided evaluation and written estimate in one visit with attention to details and my customer satisfaction. He took the time to verify my plumbing problem by video taping my water leakage of my bathtub drain pipe with his phone through the broken spaces in the ceiling. He returned the next day with Eduardo, assistant, to complete repair with pipe replacement of old bathtub drain pipes. I was impressed with Vicente's respectful, honest, confident, and professional demeanor with attention to customer satisfaction and service. Vicente exceeded my expectations with exemplary work. Bonus: I discovered afterward that Vicente had fixed my slow flowing sink faucet next to bathtub without request or charge. I would request Vicente again for all my plumbing needs in future. Thank you Vicente. You are special!"

"**Highly recommend FDL Plumbing!** Francisco from FDL Plumbing was prompt, professional, and efficient. He arrived at 10am to diagnose my water heater issue and clearly explained my options. After discussing pricing, we agreed to proceed, and Francisco had a new unit installed by 11:45am, exceeding his initial timeframe. Francisco was a pleasure to work with â he completed the job expertly while maintaining a friendly demeanor. His work ethic and competitive pricing (especially for San Francisco) were refreshing. Thank you, Francisco, for the outstanding service!"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

"Hot water heater went out in the evening, contacted HomeAdvisor the next morning, In and Out contacted me within 15 minutes, arranged to come by at 2pm that same day. They arrived ON TIME (actually a little early!!) and gave me an estimate with two options -- repair existing or replace. I chose replace. They finished the installation of the new water heater (and removal of the old one) by 5pm."
