We called Jamison first this morning after we noticed a leak in our basement. We thought the problem was our French drain behind the ( drywall ) so we called Jamison do to their great reviews . Steve C answered the call on him mobile, asked a few questions and promised to be out in an hour or so . He showed up early and got right to diagnosing the problem . He knew pretty early that it was something other than a drain problem . He soon found a leaky pipe that was the cause of the problem. He than helped me get to the pipe inside the drywall , isolate the problem and help with a mitigation plan until a plumber could arrive . He was awesome, Steve C then helped me clean up and left . There icing on the cake is that despite the hour that he was there to identify the issue - he did not charge us . This was start to finish A+ service and I give them the highest recommendation.. Thank you to Steve ..

Ryan Bond did an excellent job of leading the crawlspace waterproofing project from end to end . He was professional, on time and extremely customer centric . Additionally , the Jamison team who handled the installation lead by Jose were on time and got the job done as quoted ..

Mr. Custus and his crew was amazing two years later in my basement is still dry. They were professional and made sure to protect my carpets and protect my items in the basement. They placed the sump pump where I want it so I could still keep my bathroom in the basement also the warranty is transferable so I am very happy because I intend on selling my home , great company highly recommend ..

I would not hesitate to recommend Jamison ! Do wait for years like we did - book it now you can finally relax when the radar shows storms and flooding are on the way !

The guys were great! I’ve never had work in my home where the contractors were so concerned about protecting where they were working! They covered flooring where they had to walk to get to basement. The outside lawn was covered. They are the best! Went over the work performed answered any questions or concerns I may have had. I Strongly recommend Jamison Waterproofing! You’ll be very pleased for sure!

I’ve used Jamison twice now for two different projects. Both times Steve Custus was the lead man. He was professional and his team did a great job. Norman Brown was Steve’s right hand man on my second project. He went above and beyond to satisfy my change requests as the job went forward. I highly recommend the services of this company.

I used Jamison 3 times. The first two times my expectations were met and projects were completed on time in a professional manner. The third time was special. I had an emergency with a sump pump. Called Steve on a Saturday night and Sunday morning I had a fantastic member of the team, Elerie, show up and install a new pump and also some custom piping into an existing drain. Without this work I would still be emptying my sump by hand every two hours. This team goes the extra mile. Highly recommend.

Family has used Jamison Basement Waterproofing for years. They are honest, prompt and left the basement cleaner then it was before they got there. One of the few contractors I can actually say I trust.

After getting several estimates, I went with Jamison Basement Waterproofing because of the knowledge of the project manager Steve Custus. He didn't attempt to pressure me to sign for the estimate the day of allowing me time to think the job over and pricing.

Now that the job is complete, I am happy that I have chosen Jamison because after this past week of rain my basement has been dry as a bone thanks to Steve and his team!

Can't say enough about my experience with Jamison. Ed came out for my estimate to address an issue with water creeping in through the cinder block walls in my basement. He was know
ledgable and did not pressure me or oversell me on a solution. Work was completed as quote
d and on schedule. Shout out to the crew as well. Don, Darrien, Miles, and Kareem completed the work with great care. Apologies for any name misspellings or if I omitted anyone. They were highly efficient, courteous, and answered all of my questions throughout the process. They did a fantastic job!

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.

project went well from start to finish.
Called Brandon G He came out. We discussed my issue.
brandon promptly sent me a proposal. He returned ,we discussed details and my questions were answered.
We set a date Brandon came out with his crew 10/30/19. Donald and his cohorts did a very thorough and professional job from start thru cleanup.
They were very easy to work with and I'm quite happy with the result

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.

I am pleased overall with Jamison, but it would be helpful if the customer can be better informed about the persons being sent to do the job. By this, I mean the exact names of the persons and which of them is authorized is authorized to finalize the job and handle the paperwork at closure.
