"As a realtor, my clients often require handyman services to help prepare their homes for sale. I have referred LMA (Lou) to my clients several times and have received great feedback on the quality of his work and competitive pricing. He listens to the client's needs, contributes his thoughts on possible solutions, and delivers superior results. Lou is reliable and courteous, which makes him my "go to" guy when recommending his services to my clients."

"Moved at a great pace, took care of my permits, and the driveway is immaculate. During the site walkthrough he identified issues the other concrete contractors didn't see, and came up with solutions on the spot. Everyone on the crew is incredibly friendly as well. Highly recommend."

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.
