The hardworking crew at GNC did a great job on our crawlspace. There is no longer a musty smell coming form the crawl space. Excellent work!

All of the crew at GNC we re hard working, pleasant, respectful and knowledgeable. Gilbert is a man of his word and went above and beyond to fulfill his promises AND to satisfy the ridiculous demands of the building inspector. He handled himself with professionalism and grace. The basement looks great, the drain tiles are working as planned and most importantly, the basement is dry for the first time in 3 years. I would definitely recommend GNC to anyone

Gilbert and his team worked hard on a difficult basement waterproofing project! I have a 100 year old house with no drainage and it was awful. GNC removed 100 years of grime, put in drain tile, a sump pump, and special walls. They also included an air purifying system. To top it off, I asked them to epoxy the floors. The work looks great and the difference in air quality is epic. I highly recommend this company!

Gilbert and his crew worked diligently on our basement. They were on site when they said they would be. Cleaned up before leaving for the day and kept disruption to a minimum. All GNC personal were respectful to us and our property. We had a family emergency and Gilbert worked around our schedule. It was a pleasure to work with him. This spring we had a lot of rain and our basement was completely dry. We live on Lake Ontario and with high water levels and the rain it was amazing to have a dry basement. The quality of the work is top notch. The job was completed on time and at cost. The crew did some extra work that was not part of the job but needed done. They went above and beyond our expectations. If all contractors were like GNC this would be a better place.

They did a great job. Gave options on how to resolve keeping the water out of the basement. Offers financing which made it more affordable than taking out a personal loan or saving up the money. Would highly recommend
