Zetta completed the underpinning under the addition on my home. The existing main floor had a 325 sq ft addition added to it with a 3 foot crawl space. The existing basement has 7'6 ceilings and we were looking to add light and head room- 1 eight inch step. I began my online research and found 4 companies that would do work in Whitby. Zetta fortunately had several great reviews on Homestars which gave me some piece of mind. I contacted all 4 companies and had them all out to review the work. Each company had ideas for the project. The major difference with Victor was he listened to the fact I didn't want to lose space due to benching and that I wanted one company to own the project. Some others would do underpinning leaving water proofing, beams, and window wells for to me to complete with other contractors. I received all prices and Zeta was very competitive with an inclusive solution. I then checked 3 references to ensure I was making the right decision. Zetta 's crew was knowledgeable and polite, Raf and Brendan had to underpin from the outside and then jack hammer the existing slab and soil to dig out 5 feet of materials. This was no small task via conveyor. They even managed several laughs along the way- ask Raf about his Brazilian buddies...Throughout the project Raf and Victor kept me updated on progress, they kept the site clean, executed the project finishing on schedule and within the planned budget. The Zetta crew clearly take pride in what they do showing me every step of the way (I work from home). They made sure I was happy with the progress and work completed. I would highly recommend Zetta for your underpinning project and am open to anyone contacting me. I would add, it is worth understanding the entire scope of the project to ensure you have budgeted for all aspects. Zetta can help you with that or at least point you in the right direction.
