Basement Gurus did a great job on our city basement, sealing it up, patching holes and giving it a nice facelift. The whole team, from sales to Dylan’s install crew were great to work with and did a fantastic job and listened to my needs. They were onsite 4 days and all went smoothly. Definitely call them for a quote and talk through your issues. They listen!
