" OSC is to be congratulated and thanked for providing us with one of the most satisfying construction jobs that I have experienced. They went above and beyond their “scope of work” to make sure that every item was addressed and that we were satisfied and pleased with the end product. I believe that OSC exceeds industry standards in quality and workmanship. We are extremely grateful to you for giving us your BEST!”
—Diane M., Denver, PA

"Starting a remodeling project is like getting married. You cannot possibly know enough about your contractor before entering into such an enormous financial, emotional and time commitment. You hope that your partner will be a good communicator, honest, fair, and dependable. I got lucky and Ken Hanlin and his crew had all these qualities. I never once thought about divorce through the tough times, and I would not hesitate to get hitched again.”
—Robert and Joyce K., Boiling Springs, PA

"Ken and his crew were prompt, courteous, extremely diligent and professional.  After the job was completed, except for a beautiful new roof, there were no remnants of an otherwise messy job having taken place at my home.  When I wrote the check, I actually felt like I had gotten more than I paid for, which is unheard of in these ever-changing economic times.  Without hesitation, I have and will continue to highly recommend OSC, Inc. to my friends, colleagues and neighbors.”
—Scot and Angi W., Camp Hill, PA

“We recently had OSC construct a new deck to our house. OSC did a great job. They were able to work with our budget and gave us a terrific new space. The craftsmanship was fantastic. This was just one of many projects OSC has completed at our house and we are always pleased with the finished product.  Thank you so much!”
—Christopher and Christine P., New Cumberland, PA

“Integrity still exists truly describes the business practices for Ken Hanlin – the man keeps his word.  When OSC does my work, I can sleep through the biggest storms, knowing the job was done right.  Thanks again for everything.”
—Annette K., Newville, PA
