QSC built a gable porch roof over my deck. I had three other contractors that signed for the job before them and each one took my deposit but never started. After I eventually got my deposit back from each one I then signed with QSC. They did a great job with the construction. The job is plumb, square and took extra measures to get the shingles to match. The three sets of crew that came out were courteous and professional. Kudos to their Supervisor/project manager as he always responded within 24 hours. The company did start latter on my project than was cited in the contract and they took longer

We love our newly added roof and appreciate the time and attention Quaker State Construction gave to our project. Dave was wonderful to work with and took on a project that another builder had designed but never showed up to complete the job. Scott was our project manager and offered helpful suggestions we hadn't considered. He is extremely knowledgeable and does high quality work. We would use Quaker State again for additional home projects.

We are thrilled with our new deck! We had a couple of other quotes at nearly 3 times more than Quaker but Dave Dickson came up with a perfect solution for us. They started our job very quickly after we decided to go with them and they got it done within 2 weeks. Eric and Anthony were such professional and meticulous craftsmen who were also very friendly. We had steps to our yard added and it is such a quality staircase compared to any I have seen! We are so impressed with the quality materials and job they did as well as the cleanup. We made the right choice!

We thought by going with this company since porches are what they do it would be good...... Showed up, banged out demo, framed, put decking on...... problems really started when the roof went on and it was time to seal it so it is water tight. At this moment after about 5 visits it is still not water tight. We are getting closer and they are still returning although not without telling us we are picky. Deck is beautiful, but if you want a roof on beware. One crew can't do the entire job, it takes multiple teams and everyone wants to rush through the job to be done and leave details to someone else

We recently had had a 12x16 deck installed on 6-18-17 was very poorly built. his workers never showed up with promised. we had several things wrong with the deck, 5 boards came up. two steps was off level, when asked to come and fix we never gotten a call back. And we hired a different company to come fix. they could not fix the deck due to insurance issues. we are under a lawyer advisor to write this review. I hope this helps others to don't let company waste your money and time. Please know the company we hired did a amazing job, it only took them 3 days to complete. we gave them a review as
