"Meant to build and display a big Lego city collection as well as letting the kids use it as well. Im sure they’re gonna be climbing on it, it’s got to be sturdy and man this thing is sturdy. The finishing details are awesome and to think this is a utility type project. 10/10 will be getting more made."

"I can?t recommend this team enough! They completely transformed my kitchen, and the entire experience exceeded my expectations from start to finish. Our kitchen remodel was about $30,000, and they completed everything in just 3 weeks without sacrificing quality. They were punctual, professional, and kept me informed throughout the entire process. The workmanship is outstanding, the cabinets, countertops, backsplash, lighting, flooring, and every finishing detail came together beautifully. What impressed me the most was their attention to detail and commitment to getting everything right. They kept the work area clean, stayed on schedule, and were always available to answer questions or make adjustments when needed. It?s rare to find a contractor who delivers exactly what they promise, but they did just that."

"Jorge and his brother (Edwardo) of Gomez Vision Construction are 2 of the most hard working, honest, talented contractors anyone could hope to find. Extremely reliable and responsive. They listened and were very willing to modify things to meet our needs. Did an outstanding job feathering in new and existing hardwood flooring along with a full kitchen gut and remodel. Very fair pricing I would recommend them without reservation. We will be using them again for a bathroom remodel."

"I am very impressed to deal with Emil . The work went very professional and fantastic eventhough not completely done 100% but I am sure will come beautiful more than we expected. Very seldom now to find someone honest and professional gives advice to save some money and less money for him. Emil is available seven days a week to answer any question or concern. All crew's working from bottom of their heart like this is their own house with using technology tools to do the Job. I can't thank them enough for what they doing so far .they came yesterday very cold weather to do the work, even my neighbors told me that your construction crew's working every single day. I am highly recommended for anyone who is looking to get professional work with reasonable price and enjoy peace of mind because you are in honest hands professional people worry about their reputation and credibility. I will share some pictures of the work done so far Even though not completely finished. Also I was very impressed to hear a comments from tge rough inspectors personal who came to do the inspection stated that we are like to walk in clean job and people know what are doing good. Infact the inspector asked for phone number to recommended for other people. I will share more pictures after the work completely done ✔"

"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!"

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