"The professionalism and quality was superb. From the very first consult to the last day the owners were available to answer any questions. They walked thru the process from step one. Wendy even assisted with design. Staff always cleaned up everyday and they even became friends with my two dogs. You hear about nightmare remodels but mine was wonderful and it was a large job. Can’t wait for them to do my next project."

"I had a leak upstairs in my 2nd floor bathroom which in turn ruined most of my first floor ceiling and floors. It was stressful and I was not sure what to do first despite my insurance covering the damages. Trying to find the right people was very difficult. After much research and multiple quotes, I decided to go with JA DRYWALL. From the first day Isaias came to give me the quote, to the last day his father, George finished the painting... JA DRYWALL did what was promised and more. After each day of work, house was cleaned and livable. All of the JA DRYWALL employees were professional and courteous. It is good to know that I was able to trust a company to do the work as promised without any worries. Thank you JA DRYWALL for making my home looking like it was before the leak... It looks like a brand new ceiling. Your work and professionalism is amazing."

FAQs for addition to existing structure building service projects in Williamstown, NJ

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.
