Home Additions

All the personnel at Cornerstone are amazing to work with. Honesty, integrity, and great communication which is almost unheard of in that industry. I have worked with and known Jay for 30 years and Cornerstone will be your best decision for your building or remodeling needs.

Jay built my custom home nearly 20 years ago and we still reside in it. It remains our dream house and fortunately there is little I would change to this date. I credit this to Jay's ability to truly listen to his customer to understand and draw out expectations while sharing a balanced view on pros/cons of different approaches. I heavily leaned on Jay to provide both design and material recommendations. He provided numerous practical options while guiding us towards a short list that was manageable for us to select from. The characteristic I appreciated most about Jay was the fairness he displayed when the unknown but inevitable challenges occurred during the building process. Instead of leaving me stuck with expensive alternatives, he found cost-effective solutions and when appropriate shared the cost. To this day, I continue to reach out to Jay for advice and will forever count him as a trusted advisor.

Based on a referral, I employed Jay Frost to do some work on my master Bathroom. I was very pleased with his work and would not hesitate recommending him and his work. He is talented, friendly and dependable, a great people's personality. He'd be a great asset to anyone's designing and building needs. Thank you, Jay! Tina W.

I had the opportunity to work with Jay on several projects, and he sets a high standard for quality and professionalism. His attention to detail, strong work ethic, and knowledge of the trade really stand out. He runs his jobs the right way and makes sure everything is done correctly from start to finish. I have a lot of respect for how he works and would gladly work with him again on any build or remodel project.

I’ve known the owners of Cornerstone for half a decade. They have refurbished an entire patio for me that nearly ripped off the house from a wind storm for a fraction of what it would have cost to rebuild. They are honest, upfront, and extremely reasonably priced and don’t try to retire on a single job like other contractors who jack up their prices. If this review allowed me too I would give them 6 stars. We will definitely be using Cornerstone again and in fact are planning a bathroom remodel with them in the near future. Ted

I really enjoy working with this contractor.He is reliable,pays on time,and his work is truly impeccable . He takes pride in what he does, and it shows in every project. I highly recommend him and look forward to continuing to work together.

I've known Jay Frost for over 40 years. I have seen the completion of many of his projects including the entire build of custom homes. His work is excellent and he is a very honest and ethical person to do business with. I would highly recommend Jay Frost and Cornerstone Design and Build !

We had our bathrooms remodeled, and couldn’t be happier with the results. He was extremely professional, always on time, and communicated clearly throughout the entire process. The quality of his work exceeded our expectations, and his pricing was very fair. It’s hard to find a contractor this reliable and skilled. I would highly recommend him to anyone looking for a bathroom or any remodel needs done done right!

We hired the Frosts from Cornerstone Design and Build to help us with an update and upgrade to our condo in Scottsdale at Encore. My idea was quickly eclipsed by the astute eye of Jay Frost. Our goal was to lighten up and update the unit as we get very little light in the first floor. We efficiently agreed to an action plan for the kitchen, both baths and fireplace. The work was done efficiently and with care. The project evolved with various change orders and voila! Goals achieved and expectations exceeded. All within a modest budget. We are pleased to refer this vendor. Nancy & Gary

Jay Frost does excellent work, communicates well, and is a pleasure to work with. Highly ethical and stands behind his team’s work. Couldn’t recommend him more!

Jay and his workers were professional when remodeling my kitchen. I absolutely love my new kitchen! We had several issues come up during the remodel and Jay and his workers were able to fix the issue at more than a reasonable cost and time. I highly recommended Cornerstone and plan to use them in the future for a bathroom remodel, if I could give a 10, I would. They also took care of some flooring issues and replaced my sliding door!

I have referred Jay and Kim to my clients for years! The quality of the workmanship with clear communication and pricing are unbeatable! Highly recommended!
