"I had the pleasure of working with Dave for my kitchen renovation. From start to finish, their attention to detail and craftsmanship were truly remarkable. The contractor displayed excellent communication skills, always keeping me informed about the progress and any changes that needed to be made. Not only did they complete the project on time, but they also exceeded my expectations in terms of quality. Every aspect of the kitchen, from the countertops to the cabinetry, was flawlessly executed. Additionally, Dave was highly professional and respectful throughout the entire process. They were always punctual and ensured that the work area was clean and organized at the end of each day. It was a pleasure having them in my home."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Norman helped us to make our Master Bathroom modern and usable. The process was easy, straightforward and relatively quick! Norman's showroom was a great meeting spot to review and talk about design, choose materials and go over any details. He was communicative and helpful in answering any and all questions throughout the process. We are thrilled with our new Master Bath that feels like we are at a hotel or spa. Thank you Norman and team. Highly recommend Homecraft!"

"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 ? ? ? ? ?"

"Memo and Abby are fantastic. The communication is exceptional in both clarity and attentiveness, and the work quality - from prep to the job itself to clean up - itâ s the tops. I engaged Memo to build/install and paint, finish, and wallpaper a double-sided wall with some mill work and moulding details. For the same room I also engaged him to purchase/hang/install a solid core slab door in an existing doorway. Though not a huge job, as a designer I was really keen to work with someone on the details - and Memo was so easy to do this with and delivered on everything I wanted. I will absolutely be hiring Memo again for more things and bigger jobs."

"Inson worked with us on our home in the Hamptons and house in San Francisco. He brings an extraordinary combination of very high end style personalized for our tastes; access to special deals from the most elite and sought after designers; and a sense of working within the budget you have in mind. We were able to get museum quality pieces for both homes at unbelieveable discounts. Inson also continues to provide important follow up services as needed. For example, we had a fabric issue with our 40 outdoor chairs that developed after the warranty. The cost to change would have been tens of thousands of dollars but the manufacturer handle the out of warranty issue at no cost to us, which I believe was due to inson’s relationship and advocacy on our behalf. He’s terrific."

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