    Over soldered pipe leaking, refused to fix
    Rachael P.

    Highly recommend you keep looking for a plumbing professional. If a mistake is made good luck getting them to repair the issue without major headaches. Worst experience, terrible professionalism.

    After a power surge from the big storm, the electricity did not come back. I called 4 Service Pros to restore power. All the electrician did was to switch the basic on/off function, which switches from left (the off) to right (the on). But he still charged me over $256 for labor and $150 for emergency fee for only a 30-minute work. That's over $400! It's the biggest rip-off I've ever experienced.

    New shower/bath fixtures.

    All-around great company and excellent customer service. Technicians Zachary and Henrri identified cause of water leak from upstairs bathroom to downstairs laundry room. The leak damaged the drywall ceiling which also exposed other leaks. A technician from another company conducted the initial "repair" but did not completely resolve the water leak. Zachary and Henrri replaced the waste and overflow pipes. In addition, per request, they replaced the shower control and diverter spout and did a great job in sealing the fixtures as some of the water was leaking around the old spout and shower control handle. Thanks to Zachary and Henrri for their outstanding work. Also, thanks to the great office crew for scheduling my appointment! Definitely, a returning customer!

    New faucet on left, old one on right.

    I needed a plumber to replace my old faucets and replace my leaking supply lines. I checked Lowes for a quote and it was less expensive, but I ultimately went with 4 Service Pros because it was so much easier to reach them and schedule. I also liked that they come with a fully stocked plumber's van, so I didn't need to worry about having the right supply lines for the faucets I purchased.

    Digging out the old line and new line trench

    I had to have my nearly 60 year old cast iron sewer lines replaced at my house, inside and out. I can't speak highly enough about my experience with Matthew Loring and Stephen Savoy. First class service from the first day they showed up to do the initial inspection and quote, to job completion. They came prepared, immediately identified the issue and started formulating a plan of action on the spot. They even started locating the lines under the concrete in the basement to better describe how and where the work would be done. Due to the complexity of the work and the location of other pieces of equipment, I had planned on being without hot water and/or heat (boiler system) for a time as they removed the old lines but I was wrong. They are skilled enough that they didn't need to take them offline and got the job done in the original time frame proposed. A+ They are extremely professional, showed up on time and did not try to upsell me on anything. They truly understand what it means to provide customer service and exemplify it to the fullest extent. I would hire them again in a heartbeat and continue brag about them to anyone who will listen.

    We service all of Northern Virginia and parts of DC and Maryland.

I had several additional requests which they accommodated such as adding an extra drain line and additional return vent and all the work was done as requested. Since completion of the job, they have come back on routine maintenance visits to keep the system up and running and the cost of which was included with the original work. I therefore. have been very pleased with after-installation service. Separately, I used them for plumbing, specifically replacing a sink faucet, repairing a garbage disposal, and repairing a leaky shower fixture. I was very pleased with this service as well. Especially the garbage disposal because all it needed was a minor turn of a crank to loosen it up instead of a full replacement, which saved me a significant amount of money. Obviously, overall, I'm very happy with their services. I will be using them again and highly recommend.

It's unbelievable but some companies required upfront deposit even before assessment of the issue. Our technician,Brian,was on time,called prior,came with shoe covers,quickly identified problems with toilet,gave us estimates and couple options to think about. I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb. Can't deduct star for high prices,because they are using gas and supplies which are horrible now.

I also recommend sending photos as Mark correctly diagnosed my top issue and came up with a plan to help me bring a legacy water heater situation into compliance and make a home habitable. What I liked most was that Bill was a licensed plumber who was experienced enough to test his pipework for leaks before leaving. Star is reasonably priced for its quality of work. What I would liked even more is if Jason had showed up earlier to assist Bill earlier in carrying a water heater and uninstalling a legacy water heater. Note that it has a wide cargo truck for delivering long pipes or water heater and every foreseeable plumbing tool so it needs a larger than average parking above ground spot to succeed. My friend Walter first recommended Star Plumbing for a plumbing challenge and I am honored to second the recommendation.

I told him the bathtub in another bathroom was draining slowly and asked if he could take a look at it, he did but could not figure out what was causing the water to drain slowly, he moved a pipe around and was running the water for awhile, eventually he said he didn't know what the issue was but he could try to figure it out, I said I'll worry about it later, it wasn't a pressing problem as I never had a leak or any issues aside from water draining *slightly* slowly. We come downstairs as he's walking out, I look behind me and MY CEILING UNDER THAT BATHROOM IS ENTIRELY FLOODED. I called Mark who sent someone over but didn't offer to do anything, he left a couple of pipes for us to fix ourselves. I have an infant and water/pieces were falling out of the ceiling where she plays, we had to cut it out ourselves. Mark was so unprofessional and didn't offer ANYTHING for thousands of dollars worth of damage to my home Or even refund what they charged to come out!

He installed a brand-new water heater, and when it appeared there was still an issue, he went above and beyond by replacing it a second time to make sure the problem wasn't with the unit itself. Ultimately, we discovered that the real issue was an electrical problem with my circuit breaker, not the water heaters. What impressed me most was Matt's honesty, professionalism, and commitment to helping me get the issue resolved. Even after determining the problem was electrical, he worked with me on pricing and generously discounted his services so I could put those savings toward getting the breaker repaired. It's rare to find someone who genuinely prioritizes helping the customer over simply completing a job. Matt was responsive, knowledgeable, and incredibly fair throughout the entire process. I highly recommend him and his company to anyone in need of plumbing or water heater services.
