EXCELLENT Based on 28 reviews Posted on Google Horia PopoviciTrustindex verifies that the original source of the review is Google. I live in East York and hired G1000 (Gemil and his crew) to dig down (approx 1-ft), add benching, install sump pump, interior waterproof, and pour new flooring for the basement in my 100+ year old home. As part of the project we were also able to remove a post to create additional space, as well as replace an old rotten support post (that Gemil and his crew noticed had major issues). I don’t know much about basement work and waterproofing, and from the very start Gemil was great at explaining every step that needs to happen and why it’s important. He was also key in helping me apply for permits with the city, finding an architect and engineer to work with, helping me get multiple quotes from plumbers to do the required piping work, and managing inspections with the city. Gemil’s original quote for the work was accurate throughout the whole project. It was great working with Gemil. He was in daily communication with me via text+calls to keep me up to date on progress, his team and crew were very experienced, professional, and polite. They somehow left the job site cleaner than it was when they first started, and perfectly repaired the entry-point for removing dirt from the basement digging. I was surprised that all this work only took ~3-4 weeks. I’m fortunate I got to know Gemil and his crew as part of this project, and will be contacting him for help again on future major house work!Posted on Google J JTrustindex verifies that the original source of the review is Google. Gemil knows his stuff!! He wasn't the least bit pushy and took the time to explain everything thoroughly. Highly recommend.Posted on Google GTrustindex verifies that the original source of the review is Google. Gemil is a pleasure to deal with whether it's for home inspectors or flooring. He has a wealth of information and is a really kind person 5/5Posted on Google shirley choTrustindex verifies that the original source of the review is Google. I was looking into a french drain solution as the water from my neighbour's downspouts flowed directly toward my house, causing my window wells to overflow at times. After assessing a few proposals, I picked G1000 Home Substructure. What convinced me to go with Gemel Lacroix is that he took his time to answer ALL my questions. He even drew a diagram to show me exactly what he was proposing ! Not every company that I contacted was willing or able to do that !!! His quote for a french drain, 4x4 well and downspout extensions was also very competitive. Gemel and his crew did a great job. They arrived on time, took care to keep my lawn intact as possible, and left the place very tidy ! While he was here, he noticed my front steps had sunk and he suggested that I get them raised. Something I did not think but so glad I got this safety hazard fixed too ! My thanks to Gemel and his team for a great experience !Posted on Google Kim KaneTrustindex verifies that the original source of the review is Google. I hired G1000 Home to waterproof my basement and I have to say that I was 100 percent satisfied with Gemil and his crew. The job went smoothly from start to finish. Gemil was onsite and always available to answer any questions at any time. The job site was kept very clean and the quality of work and professionalism was very impressive and completed in a timely manner. I could not have asked for a better experience. Thank you for making a difference and caring about your customers!! Kim Kane May 2025Posted on Google L KellyTrustindex verifies that the original source of the review is Google. Had some water proofing that needed to be done. Gemil was easy to work with. They were not the cheapest price but I went with my gut feeling. They did a great job. 5 stars 🌟 all day longPosted on Google Yalini RaviTrustindex verifies that the original source of the review is Google. I had the pleasure of speaking with Gemil, and I was genuinely impressed by his professionalism, honesty, and integrity. It’s rare to come across someone in business who is truly more focused on helping others than simply making a profit. Gemil took the time to understand our situation thoroughly, provided thoughtful advice, and even helped troubleshoot the issue by taking photos to assess everything properly. What stood out most was that, despite not earning anything from our interaction, he referred us to a trusted plumber and made it clear we were welcome to reach out again with any questions or if we needed further assistance. It’s clear that this company operates with genuine care for its customers. I highly recommend them to anyone looking for trustworthy, knowledgeable, and service-oriented professionals.Posted on Google KevCarly CGSTrustindex 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.Posted on Google Wendy GrisbrookTrustindex verifies that the original source of the review is Google.
