This has taken time to share but not forgotten. I thought I could check the Homestars call for quotes feature. In May 2018, I was looking for installation of a under the sink filter, to repair a bathroom faucet and to replace a kitchen faucet. I uploaded pics for better understanding.
From the responses that came back I got a good indication of the customer service standard of each. Just through the messaging service I could see the promptness and clarity of the responses only from Lampert. I got 5 responses. Only Arthur gave a clear cost for each. He offered to buy the spare for the imported faucet and send with the plumber for which he gave a price upfront. I got a clear idea of the work and the cost. His plumber came over at the appointed hour, went about the job smoothly and efficiently and delivered as promised. Thanks Arthur.

I had good online interactions with this company through the HomeStars site and the price quoted for the work seemed reasonable. The issues arose after the plumber finished his work. The job was straightforward but the plumber demanded the top end of the quote range, which was supposed to cover any difficulties encountered with the job. I tried to explain to him the arrangement that had been reached and showed him the relevant HomeStars messages but to no avail. Unfortunately a call to the owner did not resolve the issue and the plumber became more and more insistent that I pay the higher amount. I held firm to the original agreement and he eventual departed, but not without some choice words for me. While the work seems to have been well done, I cannot recommend this company based on my experiences with their plumber and the lack of early resolution of this issue.
The owner later apologized and I hope that they resolve these customer service issues going forward, as I went with them based on the many other positive reviews.

We contacted Lampert Plumbing, to give us advice to replace our units.
Arthur was very accommodating, and very strait forward about price and installation. extremely patient to our questions, helped us to make a decision. We will recommend this company to any one who asks for a plumbing company! On time ,neat ,efficient, the gentleman who came did the work and cleaned up after himself !
very impressed.

My 30 year old bathtub faucets needed replacing. This is a job for an experienced plumber. Bob was a real pro at removing the old fixture and installing the new one. He did an excellent job and left the bathroom spotless. Thank you Bob.....

The kitchen faucet at my elder mom's condo was leaking. I was trying to find a plumber who could fix it for the next day since it was the only time I could accompany her and be present. I had called a few plumbers the night before but none of them would be able to do it in the next morning within a short period of notice. Fortunately, I found a website of Lampert Plumbing and left a message there asking for the service as soon as possible. I did not expect to get a response promptly, though since most companies will usually response customer's emails within 24-48 hours.

But I got a phone call from Arthur in the morning and told me that he would try to find someone who could do it at the same day. Israel came to our place and fixed the leaking faucet in timely manner (it took only about 30 minutes). The price is also reasonable. We are very pleased with prompt and professional manners that Arthur and Israel have done so far. We highly recommend Lampert Plumbing.

I was having trouble finding someone who would do the counter work and the plumbing together until I called these guys. Extremely professional and high quality results. They were willing and able to adapt to our particular requests, custom ordered a colour matched countertop and then installed everything and left NO mess. The finished product is flawless and we are happy with money well spent. Highly Recommended.

We recently had exceptional service from Lampert Plumbing and without hesitation consider it 10/10. We had a complex problem with the faucet in an old bathtub for which parts were no longer available. The expert attention given to the job resulted in a successful new installation. We are grateful for the timely, professional and knowledgeable attention Lampert Plumbing provided and we highly recommend them.

Purchased a new house and the first time we used the bath, the water leaked right through to the floor below.
I called Lampert immediately and my fears were immediately eased by Steve who answered the phone and let me know (based on my description) that I didn't need an emergency visit. He scheduled a visit first thing this morning.
Israel, the plumber who came to my home this morning quickly identified the problem (a gasket that needed replacing). He also checked my other bathroom to make sure it did not have the same issue.
I only wish they could have done the drywall as well!
Thank you, Lampert! I hope we won't need any plumbing help again, but if we do we will certainly call you first!

water pipe above main room ceiling froze because I forgot to replace thermostat battery . I had to cut off all water to the house to stop the leak from the water pipe being frozen. Again because the furnace didn't know when to heat the place enough due to malfunctioning thermostat on the wall the battery of which needed replacing. I will not forget again especially when going to visit friends for an overnight. Lampert Plumbing Service were happy to make a service call . Sent a super nice guy ,they did, whom anyone would be comfortable with. He was fast, efficient and very very much skilled by the looks of it and that was the most important thing. This Plumbing Co. for forty years is known as the very best.
