HIGHWAY ROBBERY!!!

Charged $466 for a 30 minute job to unclog a drain and replace the p-trap. Said that it was 1.5 hours of labor. Absolutely unreasonable prices. Shop around, and get a better deal!

THESE PEOPLE DO NOT GUARANTEE THEIR WORK.

They installed a sewer line. Afterwards, we got a back up, and since they put it in ,we called them. THEY CHARGED US OVER $400 TO SNAKE A DRAIN that they installed. In the process, they unplugged our garage deep freeze and spoiled all the food. Then they initially denied doing it.
They did not even repair our issue. The same thing happened within days of them ""fixing"" the problem, and we called them to come back. ""We paid all this $ for you to not resolve anything,"" we told them.

They informed us that they do not guarantee their work. Even if they just came out within a few days, they still will not guarantee that they fixed anything. But, they told us they'd be happy to come back out, but we'd have to pay that $400 again. We called another plumber, because
we felt like we were getting swindled.

My radiant floor heating wasn't working for some reason. Malcolm plumbing was very professional and sent Anthony over. He was great, was excellent at diagnosing a complicated situation with 6 different zones. It could have been any number of different things. Anthony took a very methodical approach and fixed multiple problems. I'm very grateful for finding Anthony and Malcolm Plumbing.

I called Malcolm Plumbing to repair a leaky shower head. I thought it would be an easy repair. The plumber spent 1.5 hours wrestling with it, only to decide that he needed to order a repair kit. He billed for 2 hours. I ordered the repair kit, and then had another plumber from Malcolm plumbing come by to install it. After 1 hour of his time (billed for 1.5), he said it didn't work and applied some silicon in the hopes that that would help. It did not. Exasperated, I called another plumber on the recommendation of a friend. He took one look at the leak and informed me it couldn't be fixed because the leak was coming from a single, unreplaceable piece. He did not even charge me for the time since it was only 10 minutes, but I still paid him for his trouble. It cost me $40 from a good plumber to find out I needed a new shower head, but then I received a bill for $1000 from Malcolm Plumbing for the time of their two plumbers who did not realize that my showered was not repairable. At no point did either plumber from Malcolm Plumbing suggest that repair was not worth the cost; when I asked, they assured me that it was worth it because my showered was discontinued and could not be replaced.

I asked Malcolm Plumbing to lower my bill a bit since they completely failed at their job. I heard nothing back. I called again to follow up, and they again said they would follow up. I've now heard nothing. So for $1000 and several hours of my time, I've gotten nothing from Malcolm Plumbing other than the lessons in finding a good plumber.

The reason this plumbing firm gets 1 star is because to do the most basic 15-minute job, they charged me over 630 dollars.

This was a simple task that I felt like they robbed me on.

Charged way to much for labor.

They charge $225 per hour (which I knew but had to use them as they are the only ones authorized to shut off water in my condo building). They also charged me 30 minutes additional time for the travel to get to my condo, which they did not tell me in advance. (why would I pay $112.50 for driving over to my place?).

To replace a kitchen faucet and the valve under the sink ended up costing $868. I have replaced faucets and valves before by plumbers (not handymen) and it costs about $100 for each.

When I called them to ask about the invoice , they removed the 30 travel time charge. When I said that it should not have taken 3 hours to shut off water, replace a valve and a faucet and turn on the water, the owner began to have a very demeaning tone and at one point started yelling at me. That stereotype way men try to bully women because they think we don't know anything about plumbing.

The owner also mentioned that their plumbers are part of a union and they pays their plumbers a living wages and benefits. I'm all for that. I'm a teacher, (union, benefits and retirement) and I don't make $868 for 3.5 hours of work and I certainly don't get paid for the drive time to my school.

In addition, the plumber who came was young (probably not a super experienced plumber). The faucet started to leak after he left. I had to call their emergency number the next day (as it was Saturday). He came back to fix it (no additional charge) however I had to change my weekend plans and wait 45minutes as he did the repair. He was an OK plumber but if you are going to charge $225 don't take 3 hours to do a 1 1/2 hour job and don't make me stressed over night because the hose was leaking all night long and waste my Saturday.

I do not recommend them. They are overpriced, take too long to do the work and the owner used a loud and demeaning.

I had a shower that was not regulating temperature properly - would randomly spew out scalding hot water. I tried working with a different plumber first, but he kept postponing and I was worried about scalding. Malcolm plumbing was able to fix within 2 days. The only reason for 4 stars instead of 5 is that they were definitely not cheap. I know I could have got the job done for a LOT less money. That said, they gave me a somewhat accurate quote before they showed up. I was just desperate for a fix.

New 50 gallon water heater purchase & install

This was the third water heater I've purchased and installed from Malcolm Plumbing since 1995. The man who inspected my non-functional 15 year old heater was extremely thorough. He found that water was coming from the roof exhaust and went up on the roof to inspect the cap. He then discovered the angle of the exhaust pipe coming from the heater was causing the water problem. When I decided to buy a new heater he gave me an estimate and took pictures of the old set-up.

When the crew came the next morning to do the installation they were exceptionally attentive to details. One thing they did was bring my existing earthquake restraint up to current code by replacing the metal straps and adding two horizontal boards to prevent the heater from moving in that direction. They also cut the flu pipe and realigned it to fix the standing water problem.

The model of Rheem heater they installed was a ""Classic Series--Professional"" which comes with many quality features and a 6 year guarantee. Although the price was a bit more than I expected, it was well worth it given the extra work they did and the overall quality of their work and the heater itself. Plus they gave me a senior discount!

All three men showed up in masks and were friendly, well informed and professional. After installation, there was a minor technical problem in getting my copy of the signed invoice but it was resolved by a phone call.

Vadim came out to repair my boiler which feeds hot water to my radiators. He is very knowledgeable and had all the right tools, and did a great job. I would give 5 stars but they are quite expensive, and the job took longer than they estimated. However, they treat their workers well (union wages), so the extra expense is probably worth it.

First, let me say that I had been a long time customer of Malcolm Plumbing. Second, I have never submitted a yelp review before, but felt that this company deserved a review. I had always thought that their pricing was high, but continued to use them because of a referral

Had a problem with our kitchen sink being clogged couple of weeks ago on a Saturday. When I called Malcolm, they wanted to charge me over $800 just to come out. Understand that it was on a Sat, but to charge me 3 times their normal rate, I thought was ridiculous.

Called another company and they charged me less than $200 to complete the job and they found out it was just a minor problem. I have found a new plumber moving forward. Maybe some of their customers don't care about high pricing, but if you do, I recommend finding another plumber cause Malcolm just lost a customer for good
