Recommended Customer Reviews

With a swift callback, he was able to tell me that he doesn't do heavy-duty street sewer cleanouts and referred another company instead. Much appreciated!

Just in case any one wondering why every review here talks about Steve, this Alfred Williams company is Steve's company and he is self-employed.
The kitchen sink in my home got clogged by food and I called Steve's phone number on this Yelp page (answered by a receptionist from an answering service company that would pass the message to Steve). Then Steve called back to me in 5mins, and agreed to come to my home immediately. He did, and pinpointed the problem immediately. The problem was a bit tricky because the blockage seemed to be deep down the pipe. But Steve worked very fast and proficiently, tried multiple times to use his machine to unclog the pipe, and finally fixed the problem. Steve also did multiple tests to make sure the water started flowing well and no leakage or the like. The entire process took 2 hours and Steve charged me $117 (for the service) + $10 (for the new pipe connection he installed), which I felt pretty reasonable given the amount of work and effort he had put into fixing the problem.
Highly recommended to everyone in the south bay area who has a plumbing issue.

Needed valves in toilet replaced. Steve came on time, fixed problem quickly with no mess and charged a very reasonable fee. I remain very satisfied with this plumber!

A year or so ago I put together a list of recommended service providers, for example plumbers, so that when an urgent plumbing event happened I would already have the best person to call based on the experiences of others. I obtained the information from Bay Area Checkbook, Yelp, BBB, State Contractor's Lic Board, etc. Alfred Williams Plumbing was on my list. So after discovering a toilet leak at floor level, I called them for help. Steve came out, removed the toilet, installed a new wax seal and reset the toilet in a very short span of time. The fee was reasonable. I was quite impressed. I have his card and for future plumbing needs I regard Williams Plumbing as a first choice service provider.

Steve is great! He came highly recommended by my mom and now we use him for all our plumbing needs. We called today and within the hour he was at our house fixing our clogged shower drain! Excellent service and prices.

Very good experience. Steve was on time, quick, friendly, happily explained what he was doing, and clearly made an extra effort to make sure everything was clean and tidy when the work was done. I will definitely call them again.

I've used Alfred Williams plumbing for several jobs. Prices are fair, service is excellent. Always on time and honest, highly recommend and will continue to use!

I called Steve to replace toilet tank bolts. He was very punctual, quick and professional!
I will call him next time!

Excellent service! After calling down the list of highly rated, but unavailable plumbers, Nelson Plumbing referred me to Steve. He was here within an hour, had me text over photos of my leaky shower and sink so he could make sure he the correct parts, quoted a reasonable price over the phone, fixed both in under an hour, and charged me the same reasonable price that he had quoted. Friendly and reliable.

Once again, Steve to the rescue!! I thought I did all the homework and figured a clogged valve kept a normal stream of hot water from filling up the tub within an hour...but Steve arrived the next day, and within 15 minutes located a super clogged pipe from the water heater and OMG...running hot water!!
