At the time, there was already some water in the basement, but I believed I had a solid plan in place to manage it—completely unaware of the damage that was about to unfold. The next day, I went downstairs to check the situation and was devastated to find nearly four feet of water filling my basement. Storage totes were floating, along with irreplaceable family artifacts that meant the world to me—pieces of history from loved ones who are no longer here. I immediately tried contacting the fire department, but I wasn’t alone in this situation; many others were dealing with flooding as well. With no other option, I had to purchase another water pump. After a grueling 10-hour ordeal, the water was finally removed. Unfortunately, the damage was already done. I lost cherishe"

"From start to finish, Hernan + crew did an outstanding job on a very big yard clean-up project. Our yard was completely overgrown. We needed to have all the weeds, leaves, and vines cleared. There was quite alot of brush to be removed, along with some small tree stumps. The crew started on-time, was always professional, cleaned up daily, and worked hard to complete the project within the promised timeline. Hernan responded quickly and was good with any necessary follow-up. The quote was very competitive (we got a number of bids for the work.) We highly recommend Eight Lanes and look forward to hiring them for future yard-related projects. "
