What Our Customers Are Saying

I have known Bob for over 30 years. His work is impeccable and always exceeds expectation. I highly recommend him both for his work and integrity. You will not be disappointed in using his services.
-Andrew Spriegel, Customer

Remodeling, or any kind of renovation, (whether big or small) can be very stressful - but having Bob as our contractor really helped alleviate the majority of our concerns and I will definetely be calling him for any future renovation needs we may have.
-Chris Carl, Customer

My experience with Bob and Cornerstone Construction has been consistent across the spectrum of projects that we have done together. Work is consistently delivered on-time and on-budget, and to say that Bob goes the extra mile is to ensure that you are satisfied with every detail would be an understatement. I recommend Cornerstone Construction for jobs both big and small.
-Kevin Hanley, Customer

Workmen are knowledgeable, clean, courteous and not afraid to explain what they are doing. Easiest remodel I've ever had! Plus, the work is done when they say it will be done and the owner is on the site frequently and makes regular calls for updates. HIGHLY Recommend!
