"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

"Excellent! Alta Renovations did my bathroom from the studs out. Tile, sheetrock, floor, vanity and the plumbing and towel hardware. The job was was in a co-op, with very frustrating "rules" and "requirements ". Most contractors would not want to participate (paperwork, time schedules and parking restrictions). Jose, the owner of Alta, abided by all the rules, whiles still keeping a smile!!! His workers worked neatly and orderly, knew exactly what had to be done, and did it. Very pleased. I'm recommending him to all my ? ? ? ? ?"

"It went very well. Inson always focused on the highest quality products that would fit the design. Also tried to get each item at the better price. Additionally he was meticulous with the project and **** ** the vendors to make no mistakes and focus on a quality outcome. Finally Inson and his team were diligent to make sure everything was constructed in the right manner. In our case the proper wiring and safest plumbing. Always relied on master builders and plumbers who new what they were doing. The final outcome was above expectations. I would keep in mind any project like ours will cost money - we spent extra with Inson but in the end it was the right thing to do and well worth it."

"Anthony is the consummate professional. He worked with us to design a porch that not only looks outstanding but adds curb appeal and value to our home we never could have imagined. He is efficient, neat, completely open to last minute "hey we forgot but could you...", incredibly excellent at everything he does (he's also done for us internal painting, fixed floor planks etc) and most important is that he is just the nicest person with whom to work on home projects. Highly recommend."

"Kenneth from JKL Construction, Inc. did such an amazing job remodeling our kitchen and living room that we hired him again to rip down our old deck and build a brand new one. Once again, he was professional, polite and knowledgeable. He offered ideas how we could put the staircase off to the side and really maximize the space on the deck. His work was beautiful and we couldn?t be happier with the results! We decided to hire him a third time to remodel the front of our house so check out those pictures to see the incredible transformation, as well as the pictures of the gorgeous kitchen he created for us!"

FAQs for addition to existing structure building service projects in Holtsville, NY

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.
