Jamison came to the rescue in our basement and far exceeded expectations. From the initial consult, Steve and team were extremely knowledgeable and professional. We were scheduled within a week for the installation and their team completed their week. We are extremely satisfied with our service and we would highly recommend for all of your basement proofing needs.

Steve continued to check back with me to see how the project was working. I had one issue and he resolved it right away. Now my basement is dry and it looks great. It was cleaned up perfectly each time. I highly recommend this company.

Sent a request for quote to Steve. He responded immediately and came to my house the next day. I received the quote that same day and installation was scheduled for one week later. The crew was very professional and knowledgeable. They showed up on time and got the job finished in one day. The basement looks great and it was all cleaned up to my satisfaction. I highly recommend this company.

My basement waterproofing project has exceeded my expectations.

I worked through a detailed proposal process with four waterproofing companies. I choose Jamison for one primary reason, Steve listened to me when I told him what it was that wanted. He worked with me on creating a plan that fit my needs and my budget. He coordinated scheduling and planning with my radon mitigation project team.

The actual installation of a French drain is a big effort. Steve brought his team to my house at the promised date and time. His foreman, Kareem and his right hand, Ryan stayed on the job for three days to complete everything we had agreed to; including sealing my walls and painting my floor.

My house is over 80 years old and my basement looks brand new.

had my crawl space encapsulated and chose Jameson for the job. Everyone at Jameson I dealt with was extremely professional. Steve, the project manager to Nasir the foreman and his crew with Miles and Dupree. Nasir and his crew were extremely polite and hard working. They were on time and stuck to their deadlines. Zero issue with my experience with great pricing. I would work with them again. Thank you Jameson.
