They completed our addition in a time manor and we could not have been more pleased with the outcome.

"Carmelo and his team SET THE BAR for responsiveness and dedication to customer satisfaction. Legacy remodeled the front of our house, including a new front door, building a portico, fixing structural damage, siding, and window framing. Transparent every step of the way. Carmelo was flexible with decisions involving sourcing materials and was informative about our options as we made decisions throughout the project. We will be repeat customers in the future; I would trust Carmelo and his team with any project!"

"Hasnain and his team at Wa did a 2nd level addition and remodel of our ranch. We were on a tight schedule and they did everything they could to get us home on time. During covid, with many supply issues, this was no easy task but they pulled it off."

"My family had the pleasure of contracting John and his crew to remodel our kitchen. We live in a nearly century-old house that was not properly cared for by the previous owner, and our original kitchen showed it. John helped us plan out a full remodel with new cabinetry, countertops, appliances, flooring, and ceiling (the latter two were originally slanted and uneven). He was communicative and thorough during the planning phase and his crew was always on time, professional, and thorough during the actual construction work. John was on site each day to supervise and keep us in the loop on how things were progressing. They caught multiple major structural/functional issues along the way that they were able to fix without it even impacting their timeline for the project. Thanks to John, my family now has a beautiful, functional kitchen. We will definitely be reaching out to him when we start additional projects in our house!"

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

They did a wonderful job installing multiple shelves in my guest room, were clean and efficient, very friendly and experienced. I was so excited to see that they provide so many services. Highly recommend and will definitely use them going forward. They were wonderful."

FAQs for addition to existing structure building service projects in Mendham, 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.
