Recommended Customer Reviews

I've owned a 118 year old quadraplex for 32 years. I've needed many plumbing repairs and used at least a half-dozen plumbers...probably more. I recently found Dejager & Reilly and they have now done two repairs. They are unequivocally the *best* plumbing company I've used--from the woman who answers the phone to the skilled plumbers. They are a small, local company, all easy to communicate with, and their billing is reasonable. I'd give 10 stars if I could. Look no further!

I have been working with DeJager for about 19 years, and have been beyond satisfied with the entire family crew. They know this building so well, old pipes and all. I highly recommend them and Candy the office manager is an added pleasure!

TRULY a family business! Proud to see Rob passing along the tricks-of-the-trade to the lil' one! We will always call on the DeJagers to fix our plumbing issues!

Our homeowners association -- as well as many of the individual owners, including myself -- have worked with DeJager & Reilly Plumbing for well over 25 years. This is an established multi-generation San Francisco family business. All of the plumbers are pleasant, professional and competent. Kudos especially to Sean and Leo. Candy, the Dispatcher, is responsive and helpful. With all the many many projects D&R has handled over the years, we have never had a problem. I recently used D&R to do a small plumbing project (in another location) replacing all sorts of faucets and toilets, and they did an excellent job, on time and on budget. If you are looking for an honest plumbing company to work with, I can't recommend D&R highly enough.

Have worked with D&R Plumbing two times and have had excellent results. The first time was several years ago, when they diagnosed and resolved a leak in my garage that stumped two other plumbers.
Most recently, Leo fixed our kitchen sink setup that had been leaking, as well as figured out and fixed a water pressure issue in our faucet.
Candy at the office is efficient and great to work with, and everyone shows up on time or within the timeframe scheduled. I am a busy real estate agent who has also recommended D&R to clients and other agents, and everyone has had positive experiences.

We use them for our annually required backflow testing. I always look forward to scheduling because the lady who answers the telephone is the happiest person on earth. The tech always arrives within the agreed upon time window, completes the testing efficiently, and files the needed paperwork.

Not sure why my previous review was deleted...
I have used DeJager & Reilly for both residential and commercial plumbing needs. They always get the job done!

Business must be good. I them called three times just to get an estimate for my 89 year old godmother's carbon monoxide spewing (turned off by PGE) boiler and they never called back. When I called them back the third time asking when we could schedule an estimate and when I told them no one had called me back, the woman said they had a ""big, emergency job with the city"" and was surprised no had called me. I confirmed my phone numbers as correct and waited again. No call. This was over a 2 week period.
I'm Done.
NOT impressed and not recommending.
It would probably be a good business practice to say right up front they are too busy for small, piddily jobs and they only deal with big jobs.
Good luck riding the housing $ tide in SF. Maybe when times are tough, you'll call the little folks back again.

I could not be more a fan of these folks. As a property manager for several years running, DeJager & Reilly are now the only plumbers I call when in a bind. They're efficient, have fantastic follow-through and get the job done right- with both time and affordability in mind. Candy at the front desk is a gem whom I look forward to speaking with every time I call. She's always readily available with realistic estimates and truly does her best to come through in emergencies. All of this combined with the personal touch one receives when dealing with a family-run business (how often can we say that these days?) wins these guys a well-deserved 5 star rating. Keep doing what you're doing, guys. You rock!

I have been a property manager for 20 plus years and I highly recommend this plumbing company. First of all they are small enough to be nimble and Candy will work with you to get the appointment time you need. Don't bother with the large companies where no on e knows your name. Patronize a smaller company with a big impact!
