"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."

Customers say: Super punctual
"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local. The last part is important because he understands the importance of reputation which gives me full confidence in his work. I will definitely be coming back to him again for any future work on my house and wholeheartedly recommend!"

"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."
