Lia5.0 / 5 ·

I decided to go with Tetra based on the good reviews and discovered they were all true. Tetra renovated our upper floor. The contract was clear and detailed. Hans and his team of skilled trades worked long days to get the work done and were attentive to every detail. They take pride in their work and worked closely with me to provide the necessary solutions as we moved through the process. A pleasure to work with, highly recommend.

Hans and the team did a wonderful job finishing my basement. These guys show up when they say they will, and communicate well throughout the project. I'm very happy with my gym-office-man cave! I would strongly recommend Tetra Group to anyone looking to renovate in the GTA.

We got our entire office renovated by Tetra Group. From start to finish, the entire process was smooth and efficient. Vahid and his team are professional, always maintaining clear communication and addressing any concerns promptly. Their responsiveness and positive attitude truly set them apart, making the renovation experience not only stress-free but also enjoyable. Happy that our office transformed into a modern and functional space that perfectly aligns with our needs. I recommend Tetra Group services to anyone seeking top-notch renovation work backed by exceptional customer service.

We were lucky to find Hans and his team through HomeStars and could not have been happier with the renovation to our bathroom. In a very short period, in the midst of severe water damage, they built us a beautiful new bathroom (including a luxury shower) and fixed all the other water damage in our house. They were kind, helpful, responsive and we were grateful for their quick response in a difficult situation

They do the full renovation for my bath and main floor. Their initial consultation, was super perfect for us . I should tell my special thanks to Hans .

Your own checks

What to check before you hire

Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire.
A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay.
Confirm they cover your area and can actually come out in your timeframe before anything else.
