"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"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 ? ? ? ? ?"

"I used K&A Home Repairs to rebuild my deck. I found them to be dependable, professional and experienced for what I needed. Anthony came at the appointment time to provide a fair estimate and followed the work schedule as close to the plan as He could, weather permitting. I am extremely pleased with my new deck and will be calling K&A for more projects on my home."

"I had a new porch built and working with Ken and co, and they were outstanding from start to finish. The crew showed up when they said they would, kept the workspace clean, and treated my home with real care. They walked me through choices, gave clear timelines, and delivered exactly what they promised. The craftsmanship is solid and the porch has already become our favorite spot at the house. What stood out most was how easy they made the whole process. No surprises, no pressure, just steady communication and thoughtful work. I’d recommend them without hesitation to anyone looking for reliable, high-quality construction."

"Ronald and his team were great. He was the first to give me an estimate and was the only one who went on the roof to inspect it. He gave me an amazing price snd was available if I had questions. His team came early (7am) and worked until the afternoon. I would recommend them to anyone and hope to use them again for more work on my home."

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