Jaco Waterproofing
I hired Jaco Waterproofing to waterproof my basement and install an Egress Window. If you are looking for Waterproofing, I recommend you look at a different company. I am very disappointed in the results. If you are looking for an Egress Windows ask that Ricky do the installation and it will be done professionally.
My original thought was to excavate the exterior of the east wall of the house where the previous owner had planted a trees and the roots had damaged the block wall foundation. After much discussion with the salesman, I went with an interior repair/ remediation for waterproofing. The salesman explained the process and I researched the products to be used for waterproofing. Both the waterproofing and the egress window would be done simultaneously by two different crews employed by Jaco.
Ricky lead the crew who installed the window and did an excellent job. He was professional and confident. I checked on him a couple times and I was impressed with his knowledge and workmanship. The window looks good and has added value to our home.
The waterproofing crew had no real leader and as far as i could tell none of them knew how to install the waterproofing system. They didn't contained the dust in the area of the basement where the work was to be done and the mess left at the end of day two took hours to clean. After breaking up the floor around the 52 foot of basement wall I thought the worst was over, no such luck. The sump pump was installed in the wrong place and had to be moved. The dimple board was installed so that my radon system was made useless and the white board was slapped up on the wall in the most unprofessional manner. There was not a sealed seam or joint in any part of the " water proofing" system. The lid on the newly installed sump pump was not sealed. My intention is to insulate and finish the basement so all the work would be hidden but as you can see from the photos the work was unprofessional, unworkman like and the radon system that had been installed 10 months earlier was render useless. I would not accept what at the ends of day 2 was "the completed" project. I spoke with the workmen and the salesman. I was not happy with the waterproofing system as installed and I was not happy with the mess that was left behind. I spent 4 hours cIeaning up stone, concrete and mud left by Jaco employees. I sent a message to the salesman with pictures attached. This was supposed to be a professional crew of workers.
On day 3, without notice, a third crew showed up to "fix" the job. After a lengthy conversation and my demand that the salesman, Charles come out to see the "completed " work, the white board, some of the dimple board and small amounts of concrete were removed. On day 4 the sealed lid was installed on the sump pump. The white board was reinstalled in a more workmanlike manner, the dimple board was caulked along the floor and where it meets the white board, although in places there is 1 to 2 inches of caulk to bridge the gap between the white board and dimple board. Brent and crew did a better job of controlling the dust and cleaning up. Eight days later the dirt left behind from the egress window was removed and the discharge pipe for the newly installed sump pump was patched so that the water was no longer leaking back into the basement. Please see the attached pictures. As it stands right now I have a "functional" waterproofing system that was partially removed and pieced back together.
I had to hire a second company to seal the seams and top edge of the whiteboard. I cannot recommend Jaco Waterproofing even though the egress window was put in and I have no complaints about it. The waterproofing is a DISASTER, it may be functional but it is the most unprofessional work I have ever seen.
