"We recently remodeled a 100 year-old Craftsman home. We initially discussed the project with Mose Troyer and were very impressed with his knowledge and advice. The project required replacing and replicating a considerable amount of the woodwork. Mose also modified the existing Shaker kitchen cabinets. Modifications included building new cabinets to match the existing ones. He also adjusted several cabinets while maintaining the original look of the cabinetry. Mose also completely built an entire wall of pantry cabinets in the Shaker style. He installed new baseboards and window trim. He rebuilt and repaired existing window trim in several other rooms. Mose integrated the repairs to the point that after painting no one could discern that the sill had been repaired. His work was flawless. In addition, he walled off a doorway and built a bookcase with enclosed shelves in the lower half. He installed 10 new doors with hardware in line with the original style of the home. He also installed two barn doors with hardware. He is conscientious and easy to work with. Without his creativity and craftsmanship the project would never have been as successful and we’re thrilled with the results. Without reservation, we highly recommend Mose for cabinetry/carpentry work."

"The roof was completed in 1 day and the ceiling leak in 2 days due to dry time. I am highly satisfied with both results. The crew was polite, professional, cleaned up after the jobs were complete, and the workmanship for both jobs were at an experienced level!"

"We hired Diamond in the Rough Construction for a home addition, and while the finished result looks good at first glance, the process was full of issues and cost us much more than expected. We chose Diamond because of Abby, the salesperson, who was incredibly helpful and responsive. However, she left midway through the project, and we missed her support. Addison, the project manager, did his best but was left to handle more than he should have. The owners, Joe and Mike, were completely absent ? no check-ins or follow-ups, even when major issues arose.There were significant mistakes, like framing the windows to the wrong size, and we were blamed for "approving the wrong windows." HVAC was also forgotten until after construction started, forcing us to pay thousands more. The trim was poorly finished with putty that didn?t match the color of the pre-painted trim, and the solution was simply to cover the nail holes with a paint pen. In the end, we can?t recommend Diamond in the Rough"

"Chris did an excellent job adding a beautiful bedroom to a part of my garage. I i got four estimates for my project and CCKA was by far the best. He thought of everything the bedroom would need and got the job done expertly. It is beautiful and exceeded my expectations. I requested he come back to do stairs renovation when he gets time in his schedule. I highly recommend CCKA Enterprises for any project you have. He is customer oriented and easy to work with. Awesome job!"

"We had R&D build us some custom built-ins around our fireplace. My wife saw some ideas on Pinterest. Rick came out we talked about what we wanted and he took measurements. Four weeks later our project is complete and my wife absolutely loves it. They were also cheaper than an estimate we got from a big box store."

FAQs for addition to existing structure building service projects in Delaware, OH

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
