Our Process


Con•struct•i•fy - v. To engage in the process by which any renovation project is properly planned, to achieve project goals while maintaining budget. [Origin - Cornerstone Carpentry & Contracting]

Synonyms:  efficient, logical, cost-effective; finally, the right way to do things.

CONSTRUCTIFY is a Cornerstone Carpentry & Contracting process that provides a systematic approach to project planning for renovation projects of any size. These steps will be applied in partnership with the design development plans: 1. identify, 2. specify and quantify, 3. modify and solidify, and 4. verify.


Cornerstone Consulting Services offers cost analysis and planning for home renovations, insurance repairs, and real estate transactions. In today's economy, we are seeing a greater number of people take a more cautious approach in matters concerning significant investments in their homes, whether it is a large-scale renovation or a decision related to buying or selling of a home. We firmly believe that an informed decision is the best decision, and have therefore developed this service to assist with the following:

Buying a Home

Selling a Home

Homeowners' Insurance Claims

Project Planning and Design Viability

Our consulting services are provided on an hourly basis. A significant return, on a relatively small investment, can be realized through actual cost savings, effective planning, or simple peace of mind.










"When we made the decision to embark on a kitchen remodel of our Hopewell Borough home, we invited several contractors in to help walk us through the process, discuss designs and layouts, establish a strategy and game plan, and submit proposals. After several weeks and numerous contractors, it was no question that Cornerstone Carpentry and Contracting LLC stood out amongst those we invited to meet with. Not only is their work second-to-none, but their communication, support, and on-time delivery of milestones of the project were impeccable. Their concern for not just the project's completion, but for the best interest of us as clients, was seen from Day 1.

It is with great pleasure that we recommend Bruce Cortelyou and his team for any upcoming project you may have."

Mark and Kate P., Hopewell, NJ

"A good contractor gets the fundamental job done. A great contractor gets the job done well with attention to details you didn't know even existed. But an exceptional contractor adds value to the entire process, anticipating problems well before they arise and giving you a result better than you hoped. By that definition, Cornerstone Carpentry & Construction is an exceptional contractor.

Bruce has that rare and wonderful combination of knowledge, skill, and desire to 'do it right.' He's got great teaching and people skills, too -- we learned a LOT from our kitchen/bar remodeling project and appreciated his many tactful ways of navigating us away from bad decisions. Also have to give a shout out to Jeannine and Kathy, who are organized, thorough, responsive, and great advocates with subs and suppliers. I relied on their opinions constantly in redoing our powder room remodel without a designer. Absolutely loved both the process and the result!"

Debbie & Moz M., New Hope, PA

"We are absolutely thrilled with the beautiful sunroom that Cornerstone Carpentry built for us. The addition is the showplace of our home! Bruce and his team were a phenomenal resource to us as we planned every detail of the room together. Cornerstone's ability to understand our lifestyle and our taste was invaluable as they guided us throughout the decision making process. The quality of the work was first-rate, the job was done on time, within budget, and it was a pleasure to work with their entire team of professionals. We were so pleased with the sunroom, that we are now working with Cornerstone to renovate our kitchen!"

Scott and Stephanie C., Ringoes, NJ

"Over the past six years we have worked with Cornerstone Carpentry on several jobs both big and small. Regardless of job, we have found that we can trust Bruce and his team to quote the job accurately and provide us options and insight as to how the job can best be completed. Most importantly, we know that the job is going to get done correctly and be held to the highest possible standard, which is why we will continue to trust Cornerstone with any house projects that we have in the future. We really enjoy working with Bruce and his team at Cornerstone, they are responsive, skilled carpenters, and really nice people."

Chad & Kathrin S., Pennington, NJ

"We want to thank you for your efforts as it relates to the renovation of our second floor bedroom and master bathroom. We heard all the horror stories about contractors and were expecting at least some of it, but it never happened. We were particularly pleased with your craftsmanship, manners and tidiness. Everything ran like clockwork, exactly as planned; we credit your professionalism and attention to detail for the end result.

Bruce, you have a fine company and wonderful bunch of folks who work with you. We appreciate you and your company for the wonderful job you did for us."

Roy & Ann H., Hopewell, NJ

"Cornerstone Carpentry has enabled our house to become a Home. We have been working with Cornerstone on home improvements since 2000. We have gone from door and window replacements, finished basements, to just finishing an incredible kitchen renovation and addition. Bruce and his contractors are always professional, knowlegable and dependable. It is difficult to find people with such dedication and skill who consider it their priority to do your project as they would do to their own homes. One of the best part of our experience was always being communicated to regarding any issues and then supported through resolution. All of Cornerstone’s staff are there to support your efforts, help with your concerns, and make your project a success."

Erica & Kevin G., Belle Mead, NJ

"I can't say enough positive things about my experience working with Cornerstone and their crew. Bruce is detail oriented, quality conscious, and expects as much from his employees as he gives of himself. We did a complete kitchen renovation and addition and after setting a realistic deadline upfront with room for expected delays, they finished right on time! When product arrived that wasn't as ordered, they were sent back and I feel that I got the quality all around that we paid for. Communication was excellent and I always knew where things stood with progress. I am thrilled with the end result and feel that my vision has come to life! I would also recommend you listen to Bruce's suggestions if he offers them! His years of experience in the business speaks volumes."
