Project manager Steve C went out to do a free basement inspection . Steve C provided the homeowners with a healthy Basement level 1 . We installed the GrateDrain drainage system ( French Drain ) at the floor wall joint where ground water was seeping in the basement. We install inspection ports along the GrateDrain system so we can access it in case of a problem, but it's rare for the system to clog and the GrateDrain system has large drain openings to prevent clogs. The GrateDrain system will drain the ground water to the GrateSump and the GrateSump will pump the water into the sewer Line , which is code in Philadelphia. Now the homeowner has a dry basement !

At Jamison Basement Waterproofing we recommend staying on top of your sump pump maintenance so your equipment will be ready when you need it. A defective sump pump probably won’t be obvious until it fails to operate when it’s really needed. By then, basement flooding and water damage could be extreme. Annual sump pump maintenance is recommended at lest once a year . If your sump pump needs service please give our service department a call at 215-885-2424 Jamison Basement Waterproofing

Our certified basement waterproofing expert, Ed inspected the interior and exterior of the crawlspace . He designed a perimeter drainage system inside the crawlspace to fix the water and moisture issue. This will include our below-floor GrateDrain sealed drainage system that will capture water and channel it to our GrateSump pump to keep water out of the house. On the outside of the foundation we buried a long discharge line and installed a catch basin outlet at the end to let water surface.

Project Manager Steve C went out to take a look at the concerns the homeowners were having with the sagging floors and cracked floor joist . Steve told the homeowners you can usually remedy sagging problems yourself by “sistering” new joists alongside the existing ones (this also works for stiffening bouncy floors) Steve also recommendation was to add 3 new 4x4 support columns placed on 16x16 solid concrete footers .. First crew Foreman Robert remove electrical cables, pipes and other obstructions. If this is difficult (it often is!), consult your local building inspector ... If a crack or sag is isolated to one area, the sister joist should extend at least 3 ft. on both sides of the problem area. But it’s usually best to run the sister joist over the entire span. When the sagging joists are level, apply a generous bead of construction adhesive to the existing joist. After we was all finish the clients noticed a big difference !
