"Jim and Danielle help me take a room that was old-fashioned and in need of a remodel into a space that is very warm and inviting. With his guidance on the day-to-day work and his ideas for how to design the space, he was a valuable resource for me through the process. He gave me lots of ideas and choices from flooring to fixtures. As the crews that came into the house were friendly and considerate of my privacy as I work from home. They worked hard and completed their piece of remodel as planned. I highly recommend Jim and Danielle Katz at Casade Customer Renovations, LLC. "

We are a family owned and operated business since 1988. You will receive personal one on one attention directly with the owner. We are a design build company that can take you through every step of your project with the utmost professionalism and detail. We always encourage communication as we schedule weekly meetings throughout your project. We do this so the project stays on track and all details are given our full attention.

"I am so happy that we found Krain Construction. Brian and his crew really brought our vision to life. We wanted to build 2 stories on top of an already existing foundation that only had a roof on it. We had a hard time finding someone to do it but Brian had no hesitation. He drew up a floor plan and we loved it. His crew built the new frame for our house, did the siding, doors, windows, decks, gutters, hvac. My husband and I are going to do the interior part of the house. If we had any issues we could easily text Brian and he would resolve them quickly. If we had any last minute changes, he would work with us. Very personable and professional. If we ever needed anything else done I would use them again and I would recommend to anyone needing a remodel. I will post some pictures of how our house started and how it is now that they’re done."

FAQs for addition to existing structure building service projects in New Kensington, PA

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.
