EXCELLENT Based on 22 reviews KevCarly CGS2025-02-01Trustindex verifies that the original source of the review is Google. Like many, the July 2024 flooding that hit Toronto impacted our home, and we had to make the difficult choice to either just repair the damage and waterproof the basement, or go with a much more involved underpinning (and waterproofing) job, that would leave us with a more open, usable basement area. After talking with multiple companies, G1000 came highly recommended and we couldn't be happier with their work. The owner (Gemil) remained conscious/understanding of our budget, timelines, and need for consistent, open and honest, two-way communication. As newbies to the world of underpinning and all the nuance associated with the plans, plumbing, and permits, it was great to have a (very) patient and understanding expert to support us through the process (and even recommend his trusted basement renovation contractor for phase two - basement finishing). We HIGHLY recommend Gemil and his G1000 team for their great work, customer focus, and professionalism. Shriraj Shetye2025-01-27Trustindex verifies that the original source of the review is Google. I recently hired G1000 Home for waterproofing and underpinning services, and I couldn’t be more satisfied. Their team was professional, knowledgeable, and efficient throughout the entire process. They took the time to thoroughly assess my property and provided expert solutions to address the issues I was facing. The quality of their work is outstanding, and I feel much more confident in the stability and safety of my home now. If you’re in need of waterproofing or underpinning services, I highly recommend G1000 Home. They’re reliable, trustworthy, and truly care about their customers! Wendy Grisbrook2024-10-12Trustindex verifies that the original source of the review is Google. Gemil was incredibly helpful and informative. He saved us a lot of money and grief with respect to a home purchase. I highly recommend G1000 Home Substructure for any concrete needs. You will not be disappointed. A highly reputable company. Navpreet Kaur2024-09-21Trustindex verifies that the original source of the review is Google. I recently hired G1000 for underpinning and waterproofing, and I couldn't be happier. The team was professional and efficient, completing the job with minimal disruption. My basement stays dry even during heavy rain. Excellent customer support throughout the process. Highly recommend their services for anyone needing solid foundation work! Joan andScott2024-07-15Trustindex verifies that the original source of the review is Google. We hired G1000 to underpin the crawl space of our home. This is a very complex project so we took our time to find the right company to do the job and he was highly recommended. We are so happy we chose G1000. It was an amazing experience and would highly recommend G1000 to anyone doing underpinning or any concrete work. As an expert in project management, with 25+years of experience, I can say that this project was well planned and efficiently executed. Gemil’s communication skills are fantastic. He ensured we are comfortable with the approach before proceeding and addresses any questions or concerns very quickly. He managed our expectations and delivered as promised. He always made the time to speak to us. This was our first project that required a city permit and many inspections, so we had a lot of questions. After every conversation, we felt reassured with clear and understandable next steps. Each inspection was passed with flying colours – the city inspectors were so impressed with the work being done. His team is wonderful – professional, on time, works hard, and cleans up every day. Our neighbours were wow’d on the efficiency of the project - they completed in 4 weeks! Gemil is truly the example of great client management and professionalism. Adam Hill2024-06-25Trustindex verifies that the original source of the review is Google. I would definitely recommend G1000 for their extensive knowledge, quality work, and superb communication! From the initial site visit to the finishing touches, Gemil was always available to answer any questions and give honest advice about the project - going above and beyond what was expected. We had lots of cracks in our foundation and serious settling in our floors, and since the repairs we’ve had several heavy downpours and not a drop in sight! Contractors don’t have the best reputation, but you can put your mind at ease when dealing with Gemil and G1000. Arash Rahimpour2024-06-25Trustindex verifies that the original source of the review is Google. Gemil and G1000 was recommended to me by a trusted friend who had recently hired them for a major sub structural work in his home. I was having lots of water issues in my basement, especially after any heavy rain. I contacted Gemil who promptly responded to my request. From the initial meet, I could tell Gemil was different from all other waterproofing companies that I had contacted. His approach to educate me on the causes for the flooding I had been experiencing, explaining the different options available to me and working within my budget, really made him standout. I could tell that this wasn't just about a job for him. He truly values taking care of his clients and delivering the highest level of quality and service. The work itself was done on time and on budget by a crew of highly professionals. They were there when they said they were going to be, and continued to provide me with progress updates as the work was being completed. Gemil, himself regularly checked-in with me and his team to make sure the highest level of service was being delivered every day. I can't thank my friend enough for having recommended me Gemil and the G1000 team. Let me return the favour and recommend you to contact them for your next sub structural work in your home. kavyn laflamme2024-06-25Trustindex verifies that the original source of the review is Google. we had very good service. Professional service and very qualified staff. Jenn Phillips2024-06-10Trustindex verifies that the original source of the review is Google. Gemil and his team were fantastic! We had a leak in our basement and I reached out to G1000. There were able to locate and solve the problem on a short time line. I would highly recommend G1000's services! Luc Bjork2024-05-27Trustindex verifies that the original source of the review is Google. Good communications with Gemil. He listens to the customer, provides honest advice (I learned that he was formerly a home inspector, and it shows), a fair price and he follows through on timelines. He also remained involved from start to finish which is a big plus when hiring a contractor. I am very happy with the work.
