Mercury builders was great and very professional. I got a recommendation from a friend and couldn’t be happier with the results. Tal is great to work with and got everything done within the said timeline. Plus he presented all options clearly. Would recommend mercury builders to anyone!a month ago Liam K

The yard of my Family home in Lemon Grove needed a retaining wall built. We went Mercury and couldn't be happier with our decision. Tal made the process simple and his crew did amazing work. Omar was also incredibly friendly and made sure that the job site was spotless when he finished. High recommend.a month ago Quentin Hnilica
