What We Build



Precise construction, well planned and timely completion.


Best work I have seen in a long time!


Brad and his crew were outstanding! Easy to work with, clear communication, punctual and a great job on our deck build. Highly recommend Cornerstone Decks!


Contractor gave a very thorough and detailed bid. Workmanship is excellent.


Brad Hisgen and his team were excellent! Work was done on time and on budget. Brad was easy to work with and delivered as promised (unlike other contractors I've worked with in the past). Finished product looks great!


Brad & his crew were very professional & experienced. Their construction knowledge, craftmanship, design & attention to detail were amazing! If you desire the Best, Cornerstone Decks & Patio Covers is your Company!


I would like to start off and say how particular I am about any work needing to be done in my home. I am VERY particular with who I hire and the quality of work they provide. So to get a positive review from me is really good. I contacted several decking companies prior to contacting this company and I am so glad I found Brad. After experiencing the deck building process and seeing how intricate it is, it really is like art work. I can’t say enough good things about Brad and his crew! After watching them build the decks it is safe to say that his crew were super professional and super nice, too! Brad walked me through the whole process and answered all my questions. He ensured my happiness. Just an overall great experience. Building a deck is no small task there is way more to it than most people understand. And not hiring the right company could be a nightmare. If you are building a deck, these are the guys you need to hire!!! They will do the job RIGHT!! Would definitely recommend. DOUBLE THUMBS UP!
