Testimonials 
"I wanted to pass along my sincere thanks to all the people at SGS for raising our foundation floor. From the estimator Keith Burns and the scheduling coordinator John Cook to the service technicians who completed the work, the professionalism was first class! When I told my neighbor what I paid as opposed to the cost of replacing the floor, he was astonished!!"
Patricia Fontaine (Homeowner) - Slabjacking "SGS has provided services for us for over 20 years. They are great to work with and are always available for emergency work including nights and weekends. John has always made sure we are a priority and the crews he sends are experienced and efficient."
Kenny Payne - (Pepco) - Leak Sealing Conduits "We prefer using SGS for all of our concrete crack repairs and pipe penetration sealing because they are always willing to accommodate odd hours in all of our tenant buildings. The service technicians that work on our various properties are always professional and leave a very clean work area when the job is complete."
Tony Wells - (Hines Interest) - Concrete crack repair/Pipe Penetration Sealing "We have used SGS on several of our projects for waterproofing below grade brick and cinderblock foundation walls. We have not found any other waterproofing contractor that uses the specialized products that they do for every type of situation. We have had other companies attempt to repair below grade leaks to no avail and SGS has come out and gotten the job done without fail!"
Steve Nuerenberg - (Linden Contracting) - Waterproofing/Leak Sealing with Chemical Grouts
"When we found various voids on our project site, other companies would not take the job on because they were too small and too spread out. SGS stepped up and took the project on and kept our homes being built from falling behind schedule. We would definitely use them again in the future for any of our developments that needed this type of work or any other services they provide."
