Concrete Foundation Repair
Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs.

Alex, the owner and lead contractor was a pleasure to work with. From start to finish the process was seamless. The waterproofing process was explained as well as the benefits from performing the work. Alex was personable, professional and knowledgeable. The pricing was very fair and competitive with the highest quality of workmanship.

He always delivers exactly what he promised. Not only was the quality of the work top-notch, but Alex also made the process stress-free. Communication was excellent, the job was completed on time. After working with Alex on a number of jobs I’d highly recommend Alex and his company to anyone looking for reliable, professional water proofing professional.
