I cannot say enough great things about Pshem and Jakub and their family-owned construction company! They recently installed tile flooring in our kitchen and foyer, and the results are absolutely stunning. From the initial consultation to the final touches, their professionalism and attention to detail were unmatched. Pszem and Jakub took the time to understand our vision, offering helpful suggestions and ensuring we were completely satisfied with the tile selection and layout. They worked efficiently without cutting any corners, and the craftsmanship truly speaks for itselfeverything is perfectly aligned and flawless. Not only were they incredibly skilled, but they were also a pleasure to work with. They treated our home with respect, keeping the workspace tidy and minimizing disruption throughout the project. It's clear they take immense pride in their work, and it shows in every aspect of the finished product. I highly recommend Pszem and Jakub to anyone looking for quality craftsmanship and exceptional service. We will definitely be using them again for future projects! Thank you both for making our home even more beautiful.

We had old decks and fence that needed replacing. Deckmaster was patient with us as we worked out the timing and they were able to do our project before season end. The job was lightly complicated with an upper deck and lower deck built 30 odd years ago. Oleg and his crew made it look easy. They did a great job working flat out and finished in 6 working days. All in all, great value in our opinion. Thanks Oleg.

This company did our flooring job recently and they did a horrible job. My floor is shaking, my baseboards are misaligned, they are badly finished, poorly painted. These guys just don’t know their job. I now feel I could have done a better job myself. They would charge you 90% upfront and would then never deliver. I am so disappointed amd feel so sad for myself for getting my place spoiled and wasting so much money. I won’t recommend them at all.

Build or replace decking- 22 Oct 2025
Artem of Novo Building was very professional and skilled. After a site visit and discussion, the project estimate we received included a very detailed list of the cost of materials and labour which we really appreciated. He was friendly, detail oriented, listened to what we wanted and had great suggestions on how to make the deck better than our expectations. He did an awesome job removing our old deck and building our new one. Our neighbour came by, was so impressed with the deck he immediately asked Artem for his business card. We would definitely hire Novo Building again. Bruce

We couldn't be happier with the job StarTech Stucco did. From describing the work that would be done, to extremely tidy set up and ongoing work to the finished product. The team was both respectful and experts in their workmanship. If you need exterior stucco done, I recommend StarTech Stucco every time.

You cannot trust their estimate. I contracted them to build a second floor addition, and after supplying them with detailed CAD drawings, architectural plans of the existing house, and all the information they needed to provide the most accurate and realistic estimate possible, they later increased some of the biggest costs to MORE THAN DOUBLE what they had estimated. One could accept increases of up to 10% or 15%, but not over 100% when there are no changes or unforeseen circumstances to account for them! They claim that they work with you and keep you on budget every step of the way. That is not true. The designer had not even looked at the estimate to begin with, and during the design process, I was not able to get any pricing until the design was finished. And then they put obstacles and threatened additional design costs when I wanted to go back to make the necessary revisions to reduce a large cost increase. That was the first of three instances in which they doubled costs for no other reason than having made a mistake or omission in their initial estimation. This is by no means the honest, customer-focused company they profess to be. They do provide a more itemized estimate than other builders, which is why I chose them. But when they increase costs by so much for no valid reason, the estimate means nothing. In short, after two years spent correcting the designers constant mistakes (which also delayed permits), waiting for updated costs and information, and disputing unfair cost increases, I had to give up the addition before construction had even begun. Besides the disappointment and aggravation, I have also lost a non-refundable deposit of over $20,000 plus the cost of all the permits.
