  We had an amazing experience with this contractor during our office renovation. They repainted the entire space, built a new wall to create an additional room, completed a full bathroom, designed a beautiful accent wall behind our fish tank, hung all new artwork, and built custom office desks. The workmanship was excellent, the process was smooth, and the attention to detail really shows. Highly recommend!

  Dmytro and his team worked on a demo and repour of the concrete slab of our basement. The team worked quickly and efficiently, and despite some unexpected, prolonged issues with our permit, they returned the day after issues were resolved to continue work. They were attentive to our needs and the work was generally to our satisfaction, especially for the very competitive cost of work. Dmytro was ever present during the work. My only complaint would be that communication could have been better at times, as there were days where no one could understand English and we were more or less in the dark about the work that was being done. In a similar vein, a window was removed for the duration of the work, but we were not aware that it wasn't going to be put back until the last day - which a little more communication would have solved.

  My first interaction with Andre was very positive, he seemed very knowledgeable and asked questions about the age and history of the home. He also said he only did one project at a time, and didn't start the next one until the previous was complete to our satisfaction. This feeling did not last very long once we had paid the deposit for the renovation. The original scheduled start date was in November. In October we received an email that it was delayed until February. Actual work didn't start until mid March. We agreed at the start of the project that if he needed to stay late if he was going to waste material (like grout or cement). What happened instead was he showed up most days between 10am-1pm and stayed 6-10 hours. Halfway through the project I clarified that I only wanted him in the house between 9-6 and the extra leeway was only for special circumstances. He came on time one day and returned to arriving between 10-1 after that. When demolition started, we was surprised that the walls of the 1930's home were not drywall, and had not heard of rocklathe that the walls were actually made of. He was also surprised the tub was made of cast iron. Both of which he charged more for above the quote price and added 1 week on the 2 week project. Once the bathroom was almost done, I had messaged him to confirm I was able to use the tub which he had tested. Once it drained, I noticed the ceiling below the tub was leaking, the original pipe was held together with epoxy and had come loose from the renovation. Another added cost, and I had to replace my own ceiling, he wanted to charge more and he was behind on the next job. He also moved the bathroom light switch to inside the bathroom, which was also not tested (it turned off all lights upstairs). The light switch move was a line item in the quote and paid for, but when I told him about it he would not entertain fixing the issue. In the end I will need to change this myself, even through I have paid for it and is a line item on the "add-on" quote. Other short nitpicks: - He did not install a shower curtain rod (not specifically called out in the job, but I had assumed that would be included) - Tiles not all flush with the wall, some sticking out - Did not get the tub we wanted, apparently it was out of stock on back order (we paid him the deposit 1 year before the work started) - Shower head was not installed well, o-ring was crushed and was leaking. Luckily I was going to replace with a different head so it was an easy fix The frustrating part is the bathroom itself is well done. If the Andrei and Jessica had just given an accurate quote from the beginning and did the work they said they would it would be a 9-10 star review. They are both very personable and very good hard working people. In the end, I would have been better off with a different company who quoted higher but had explicitly called out the complexity of working on an older home and likely wouldn't have had the surprise cost.

  Install or replace heating systems- 5 Feb 2025

  Fantastic experience, look no further. I had Enercare come in and tell me I needed a new furnace because I had a crack in my heat exchanger, tagged the furnace as unusable, they even showed me a picture on his phone. I requested quotes through HomeStars for a new furnace and Richard called me back. He was very thorough and honest. He asked how the crack was diagnosed, and after telling him he said that didn't seem right. I had him come in to give a second opinion for $200. I watched as he opened up the furnace, take pictures, look through the scope etc. No crack to be found. Enercare had shown me an old picture. Richard even fixed the humidifier that was installed incorrectly, gave me some helpful hints and tips, and removed the tag. Richard is a friendly and outgoing individual who saved me thousands with his honesty. I highly recommend CoreTemp for your furnace needs, thanks again Richard!

  My furnace was not turning on. So, yesterday I called my HVAC maintenance company (not Ultrabin). The tech found a faulty power switch but he also said the equipment was not safe to operate. He put a red tag on my unit, he turned the unit off and left. I then called Ultrabin coz I thought the previous tech didn't do any testing. Paul from Ultrabin came to my house right away. He did many tests including CO tests, gave it a good bill of health. Highly appreciate Ultrabin's (Eric's Team) promptness to help with the situation, my regret is that I didn't call them first.. thanks again Eric and team, you guys made the uncertainties go away!
