Recommended Customer Reviews
Steve S.I could hear water running in my main level bathroom, but I could not figure out where it was leaking. I tried shutting off the water main but was having issues with that as well.
I called C4, and Mark showed up within 15 minutes, had the ceiling cut out and located the leak within 10 minutes, and had everything repaired and operational within an hour and a half.
I don't have the slightest idea what the going rate for a plumber is so I can't say if his prices were fair or not. I can say that I was very pleased with his response and his work.
I would definitely recommend him to anyone.
Update for my review just beware of plumbing companies that just throw out a quote after a quick assessment by walking through and doing nothing. My problem wasn't even plumbing related it was a leak dripping from my hot water heater into the floor missing the drain pipe causing the leak in the ceiling below. So if they were so professional they would have found out the real cause and not trying to get over with outrageous quotes. When you have someone to come to assess the issue whether they charge a trip charge or not you would expect them to be honest this is not the case with this company. So beware of the plumbers that are just looking to swindle you .
T G.I would be wary of using this company. Witness their driver in a wrapped van get over without a blinker and there was a car in the lane right next to him. And he kept going all the way. Luckily the lady saw him at the last second and swerved causing a big truck in the fast lane to have to swerve too otherwise it would have been hit by her. Super careless and due to the fact of the lack of blinker, it's apparent that the driver could care less about other people. I suspect that reflects in the quality of the work. This review is my opinion.
Buyer beware - C4 Plumbing is HIGHLY overpriced and I'd say they borderline on gouging customers. They will do a decent job and they have professional workers who will do decent work, but they will charge 3-4 times the price of a normal plumber who will do work equally as well. Shop around!
I hired C4 plumbing to come check out my nonfunctional air conditioner in early April. Two younger guys came to diagnose and clean my AC on 4/7. The workers power washed my AC unit before telling me that was their plan, and now the AC won't switch on at all. They told me that I was ""low on freon"" but they didn't have any freon available and would get back to me. Despite my calling multiple times and getting a promise of service and ""put on the schedule"" on several different days, I still have a nonfunctional AC unit a full month later. I have a medical condition that makes me particularly sensitive to being exposed to heat for prolonged periods of time, so this entire month of fluctuating temps has resulted in making me quite ill.
I'm fully aware that air conditioners are closed units that are designed to not allow freon to escape, and that freon doesn't need to be replaced or ""topped up."" Instead, my unit is probably leaking. I'm also aware that power washing an AC until will most likely damage the coil. I'm not thrilled that the AC techs either thought they could scam a woman or that they weren't knowledgeable enough to diagnose, clean, and fix the AC properly. I should have listened to the negative reviews before hiring. Zero stars.
Concerned C.Freezing temperatures caused a pipe to burst in our laundry room. Called a number of plumbers but C4 were able to get to us in the shortest time frame. Plumber was punctual and gave us an estimate before work was started. Excellent communication and they made sure we understood what was being done to fix the problem as well as mentioning things that could be done to avoid this issue in the future. Work was fast and cleaned up very well. I highly recommend their services
I've never written a review before, but thought other people need to know. This company significantly overcharges the customer. We had C4 plumbing come in to replace a 2 foot section of ABS drain pipe. The final charge was $900 with a 10% discount. The actual labor took less a half an hour. Complete ripoff! I will never use C4 again and if someone asks who I might recommend I will start off by saying who not to use-C4. Buyer beware.
Had an outside pipe leak in a newly owned house. Mark talked me through how to shut it off over the phone. He did not have to do that, so a thousand thanks to Mark. We can now get landscaping company out to blow lines!
David S.I try and refrain from award all stars because it can cause grade inflation quickly . I stop at just before the hugest rating. So understand what I mean, please.
C4 Plumbing merits close to full rating. In terms of Local, nearby, live person, who works there, phone service, respectful, sooner than estimated in all aspects, and finally, in repair or return-to-Service efficiency and economical.
My water system repair was in a tight space, hard to get to, and compounded by other difficulties, including never at the best time to fail.But Technician M, made a quick evaluation, offered a quote, and was finished within an hour.
I find it difficult to point to any areas where improvement could be suggested.
I can't offer a picture because I am in bed after a relaxing shower. I am going to sleep well.
Samir A.Caught a leak from our kitchen sink basket and Jeremiah came out the next morning. Fixed it all up and gave us the chance to swap out some of the problematic piping that was causing some unrelated odor issues.
Not the cheapest guys around but you get what you pay for, *especially* with plumbing. I know first hand that water has a way of making you ultimately pay for shoddy work so it was worth it to have a master plumber service something we use so often.
After the job was done I had asked about a purifying system and he was ready with literature and was very knowledgeable on just about everything I asked him. He was very personable and just an overall nice guy to talk to.
Highly recommended and will reach out again for any other plumbing work. A+
