"We are very pleased with the new deck build by Bryan and his team. They first tore down the old deck to the frame, which was still in good shape. They then rebuilt the deck. They replaced the floorboards, the side railings and boards, and the steps. It looks great and is very solid. See attached pics."

"BelMax did several projects for me including two major projects; (1) remodeling a basement bathroom with the addition of a shower and adding a second-floor addition to the house which became a walk-in closet. BelMax worked with an architect to get a solid design, pulled the permits, completed the work, and got the work approved. I am very pleased with the quality of their work. Throughout the job, the crew wore masks and shoe coverings when they worked inside, which I appreciated. They were also very clear about what was budgeted for each minor project so that later when we changed some of the requirements, we were able to work together to figure out the change in cost. Please note that some of the changes in scope were required. For example, after prior to the work stating, the architect said that we had to add another bedroom window to the house to meet city code. I recommend them and would consider them for work at my house in the future."

"Iâ m not one to write reviews but I feel compelled to let others know how grateful we are to Hasnain and his team at Warraich building company. He is a shining example of how a business should be run. We were extremely fortunate to find someone so honest and caring, especially during COVID and these crazy times. I was expecting our second child at the time we met Hasnain, so it was extremely hard to be onsite as much as I wanted to be. As first time renovators for our big job (gutting and expanding our one hundred year old house in Millburn, NJ) during COVID, pregnant, and completely overwhelmed, Hasnain held our hands throughout the entire process. When baby was born, I resorted to texting Hasnain in the middle of the night often and Hasnain always responded, even on weekends. He performed an outstanding job to our utmost satisfaction and we are so proud of our new home. Throughout our 1.5 year renovation, Hasnain was straight to the point, patient, caring, meticulous, intelligent, tech savvy, reasonably priced, transparent, upstanding, stuck through to the end, and we are glad that we can call him our friend. We will be recommending Warraich Associates to all of our friends and family. Thank you Hasnain and team!! With warm regards, Stefanie and Qin"

After spending almost 7 years working to make other companies clients happy, I was able to confidently come to the conclusion that I could not only do it better, but also offer a wider range of services that cater to big and small customers alike. In a world where prices and effects of services are ever increasing, I would like to be the grounded affordable option to make sure that families can get the work they need done and not suffer for it financially. I want to be the one that shakes up the game and makes sure everyone can feel confident and proud of the home they own.

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