These guys knocked it out of the park! I had wood built on top of concrete whenever I became disabled. I asked CNS to redo the porch and make it into a patio. They extended the porch with concrete, added rails and put in a drain. I picked the color of the concrete to match the house. It looks amazing! I've gotten so many compliments already. It's definitely boosted my mood!

We had Chris come out to talk about removing and replacing the back porch on our 100-year-old house. He was extremely thorough, easy to talk to, and made sure all our questions were answered. We also appreciated getting to see some samples and our estimate during the initial visit. Thanks Chris!

We had a very positive experience with CNS and would highly recommend them for a deck. Customer service was great and the final product met all of our expectations.

The contractor completed a recent roofing project on my entire house in an expeditious manner. The job was completed by noon time of the same day. Very satisfied with quality of workmanship, clean up, and same day dumpster removal.

Outstanding and very professional. Very good experience throughout. The company and technician are 5 Star.

We had impressive consultation regarding options for replacing the old siding on our house with Hardie Plank. Chris and Nick were prompt, professional and very thorough. They were open to all questions, checking to make sure that they were answered to our satisfaction. The 3-D rendering was extremely helpful as was being able to handle samples of product.

Nearly 110 Squares of new roof, gutters, and fascia. Our church's roof was in bad shape and we were experiencing leaks and ice damage and the roof was only 15 years old. We received competitive bids from multiple companies. When we met with Sam, one of the owners, he brought the GAF Rep and we talked through the entire project, how the shingles are constructed, what type of underlayment they use, and how the new ventilation technology works.

No one else did that. To top it off, they were one of the lowest bids. We were not disappointed. The crew was excellent, the workmanship was fantastic, and they worked to keep the site clean throughout the project. We have a 50 year roof, and it has completely transformed the look of our building. I highly recommend CNS Construction.

They did an amazing job with the construction of our deck. Their crew is very hard working and very respectful it only took them 6 days to tear down the old one and put up the new one under roof. You won't be disappointed with this company. Sam is always available if you have any questions or concerns.

I am so happy with the work done on my home by CNS and their crew. They removed old wood shingles from my second floor and replaced it with vinyl shingle siding. It looks great! I'm so glad I discovered CNS. Sam is such an excellent representative of his and Calvin's company and I'm grateful for the opportunity of getting to meet and know him. I had three other bids for the job but when Sam came to the house I knew in a sort time that he's the one I was going to trust to do the job.

His knowledge, confidence and personal ethics made it an easy decision. Everything went smoothly. Sam was here before, during and after the work was done to make sure everything was going well and that I was happy. I am Happy . I will absolutely recommend CNS to everyone I know or meet who needs work done. Thank you Sam. You made the whole process a pleasure.

We had the best experience with CNS building our deck for our new home. Sam was extremely responsive and willing to revisit our plans until we were set on the perfect design. Our questions were always answered and we felt at ease through the entire process. I highly recommend CNS for any project you can dream up! Professionalism.

I can not say enough positive things about this company! I was able to easily schedule an IN PERSON appointment and was given an estimate at that visit. No waiting! Sam was very knowledgeable about products and made great recommendations regarding our back deck replacement. They are quick to reply to calls & text messages and keep you informed at every step of the process. Last, but not least, their workmanship is incredible!

Sam was great to deal with. Answered any questions we had and showed up when he said he would. Knowledgeable about his trade. I would recommend him to everyone. Value.

What more can I say? CNS Construction will always be my answer when someone asks for a recommendation for a local roofing company. Sam is professional and the quality of work his team produces has achieved the coveted status of having not one, but three stamps of approval by three different Pittsburgh dads. I contacted Sam after seeing a really cool looking deck on a house down the street. He passed the vibe check. you know, the one where you don't feel strangely violated after the contractor explains to you something you already know for an hour and then quotes you for what will likely be subpar work. Sam worked with me and was patient with my insurance weirdness.

Once the project started, he ended up discovering not one, not two, but four layers of waterlogged shingle sandwich on my roof. The crew shoveled garbage shingle for what seemed like an entire week. Those guys deserve a gold medal for real. Sam also dealt with harassment from my excessively angry neighbor who is the type to be angry no matter what is happening. 0% passing rate on the Mr. Roger's neighbor scale. The roof looks excellent and the quality matches the appearance. 10/10 would work with Sam again.

C&S Construction put a deck on our house, and my wife and I are very pleased with the outcome. We think they did an exceptional job. All of the guys were very polite and professional! We highly recommend C&S Construction! Value.

Calvin and his crew were very professional and did a wonderful job with the deck replacement. Creating a beautiful space. Clean up was amazing. I definitely will use them on future projects. Value.

There are no two better people in the world then Sam and Calvin to build your deck! They are extremely helpful, creative, respectful, and kind to work with! Value.

Sam and the crew were very polite and professional. Sam responded quickly to texts and emails. Construction began on our deck right when Sam said it would. The quality and workmanship are top notch. We highly recommend CNS Construction.

Sam and Calvin Milligan from CNS Construction replaced my fairly large deck floor and railings within three days. Sam thoroughly explained the work and gave a very fair estimate. Calvin kept me informed of the progress as they and their crew progressed. They were considerate, pleasant and easy to work with. Great experience! Impeccable work and very professional. I would highly recommend them to anyone wanting prompt and competent professional work done.

I just recently purchased a deck from CNS. The deck itself is a great deck that is exactly what I envisioned. What really stood out for me with these boys was their attention to detail and their service oriented attitudes. They went above and beyond to satisfy our requests. On top of it all, they were able to complete the deck in a matter of days.

This company is amazing. they showed up and started working taking down my old deck and replacing it with the new deck. When done they cleaned everything up as they said they would do. I just love my new deck. I have had so many compliments on it! If anyone is looking for a good company CNS Construction is the best. Decks, Roofs, Siding, Kitchen and bathrooms. You could not find a better group of workers!
