"I had my 1960s paneled and drop ceiling basement room remodeled. I cannot tell you how pleased I am at the upgrade. Along the way Gary answered many emails and calls in a timely manner, usually within the hour. He gave me updates of when certain parts of the project would be worked on and made suggests on things that I hadn’t thought about ( like replacing the drafty original windows while construction was happening). He picked out doors and ceiling fans that were perfect since I am not good at decorating. Because GJP has all their own contractors there was no wait time between the remodeling of the walls and the electrical work that needed to be done.

Called 3X no return call Told me to call accounting and no one answered and the voicemail was not set up ??? Customer service is very, very bad. I would NEVER do business with them again!!!!"

FAQs for addition to existing structure building service projects in Port-penn, DE

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.
