I just had a service call by Stong Plumbing. They were here the same day I called them them. The technician diagnosed my water leak problem and resolved the situation. I have used Stong in the past but have never been so amazed and happy with the outcome of a service call as today. I was only charged a diagnostic fee. Spent less than $100. Tell me when you can do that with a plumber! They are local here in Malvern PA. I'll keep using them in the event more plumbing issues come up.... Fred

Offered a quick and fair estimate and scheduled the repair in a timely manner. Grayson was courteous and did great work in replacing the old exterior faucet with a new frost free faucet. The entire work area was clean. Would highly recommend.

Bottom of the barrel plumbing company. I dont think these idiots could fill a kiddie pool without screwing up. They ****** my parents out of $45k to ruin, oopss I mean remodel their 8 x5 bathroom. They didnt use stainless screws when hanging drywall, so theres now these beautiful decorative brow spots all over the drywall (rusting screws.) They used incorrect caulk in the shower which started cracking, allowing water behind it. That led to use finding out they didnt use any waterproofing material behind the tile shower!!! Their so called plumber also has zero clue how to sweat a copper pipe, he used so much solder that the pipes were partially blocked internally. They set the floor tile pattern incorrectly and were pissy towards us when we made them tear it out and fix it (we literally printed a picture of the exact pattern we wanted) They couldnt even hang the medicine cabinet straight and I had to fix it. The dry wall spackling is jacked, I couldve grouted better with a butter knife. Its seriously embarrassing that a diyer with some common sense is more capable and knowledgeable than the professionals After looking at all of their other awful reviews, its scary that this company is still in business, also notice how they arent accredited. Save your money and sanity, and stay VERY far away!

This was a toilet emergency right before family arrived during Thanksgiving weekend. To our amazement, the plumber arrived within an hour of my call and quickly resolved the unpleasant problem!

Grayson the tech was fantastic! He was at my house within the hour after I called for a failed sump pump and my basement was flooding. Grayson installed new sump pump within the hour. He was very knowledgeable and keep me in the loop the entire time he was onsite installing the sump pump. Highly recommend Strong Plumbing especially if its an emergency.

Stong had my $500 deposit for a year and a half and made no effort to schedule the work. I probably called 40 times and every time Gina said she would call back tomorrow. That never happened. Not once.. I had to call a dozen times just to get my money back. I heard "The check is in the mail" over and over again.

I appreciated how quickly they responded to my inquiry and how quickly they were able to come out to do the work. Though I felt they were slightly pricey I would definitely rec this company. The guys were friendly, respectful and went above and beyond. I would hire them again if I need them in the future. A+ rating

Positives are that the person that showed up (Grayson) was polite, professional and did quality work quickly. My negative comment is more with the HomeAdvisor aspect of this experience rather than with Stong Plumbing. Once I registered my project, HomeAdvisor then sent me multiple emails which set expectations for a price range that turned out to be noticeably lower than the eventual quote from Stong Plumbing. To Grayson's credit he then helped me by pointing out a coupon that I could take advantage of. That was greatly appreciated and reduced the overall price but didn't get me down to the incorrect expectations set by HomeAdvisor.
Response from Stong Plumbing

"I am very sorry for your experience, I believe that HomeAdvisor may also be selling services as well as providing contractors with leads. I was told by HomeAdvisor that once you go into a certain area you can see pricing, and I do not believe there is the language of who would do it for that price. I have had this problem on several jobs where the HomeAdvisor set an expectation for the job price prior to us ever arriving. I am glad we were able to complete the service for you with the coupon."
