"Bobby and David provided great customer service, high quality work and excellent pricing. For my new kitchen, I had an interior wall removed (they brought in a structural pro to check for safety) , moved plumbing and added electrical. The entire kitchen was gutted and redone. They helped me with all my flooring and cabinet selections- they really know what works best! All my phone calls to them were returned very quickly. I highly recommend them and plan to call them back for more work!"

"This was a fairly big job to completely remodel our unfinished 1000 sq foot basement. The job took about 5-6 weeks to finish. Jeff showed up every day with his small crew and did an amazing job. Jeff was easy to work with and delivered everything we asked for. We also had Jeff's team replace our den floor with a heated tile floor which came out amazing. In addition, they also resolved a complicated leak that required some detective work to determine where it was coming from and thy were able to find and resolve the issue. I would highly recommend Northgate! Thanks Jeff!"

"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 ? ? ? ? ?"

"From beginning to end the process was flawless Let’s just start by saying not only was communication and follow up excellent, but unlike a number of contractors, Coco s team shows up punctually and on schedule. The work is priced fairly and done with skill and precision. My neighbors inquired about work on their home after seeing this company in operation. All work was explained and progress updates were provided. I’m totally pleased and would not hesitate to recommend them to anyone, and I have, and will continue to recommend them and utilize their craftsmen going forward"

"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."

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