"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

"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 ? ? ? ? ?"

"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."

"Absolutely, I’d be happy to help you out with that review! Here’s a glowing one for Tri Build Construction and Ray: --- I recently had the pleasure of working with Tri Build Construction, led by Ray, and I can't say enough great things about the experience. From start to finish, the work was absolutely fantastic. Ray and his team were the epitome of professionalism: they arrived on time, communicated clearly, and maintained a clean and organized workspace every single day. Not only was the craftsmanship top-notch, but the attention to detail really stood out. They took the time to ensure everything was done exactly as we envisioned and even went above and beyond to accommodate a few last-minute tweaks we requested. The final result was everything we hoped for and more. In short, if you're looking for a reliable, skilled, and incredibly professional construction team, I highly recommend Tri Build Construction and Ray. They truly deliver a five-star experience!"

"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."

"Hired Elevate Construction for major home renovations and bathroom remodeling. They fixed electrical issues, painted, gutted and restored multiple rooms in my home that were severely damaged. The team was diligent and professional throughout. I was impressed by the quality, flexibility and commitment to finishing the job in the small timeframe I needed it complete. They put extra care into making sure each step of the project met my expectations and had excellent communication. Will hire again for future projects."

"The construction company, MGT Construction has just completed our +/-600 sq foot deck at our home in Southold. MGT managed the planning: We were determined to build the deck per Southold Town code using Timber-Tech composite decking and railings per their specifications. After we had the survey done Steven coordinated with their architect and liaised all building inspections. He was instrumental in all follow-ups with the town until final approval of the permit. We sourced the pressure-treated framing lumber from Amagansett Lumber and with four feet deep footings the underlying structure is solid and constructed to last 30 years, which is also the guaranteed life of the decking. MGT Construction excels in the carpentry aspect of the decking. They made sure the planks were correctly aligned and the surrounding picture frame planks were precisely fitted. This was also true as well regarding the fitting of the railings. We opted for “drink rails” and their finishing on those is superb. Our overall impression of the construction staff was that they were always courteous and friendly. We did however make the observation that the workers should pay attention to their attire, which at times was needlessly sloppy and awkward. However, they were hard workers and respectful. An electrical subcontractor had to redo work because a supervisor was not on the site. The work was corrected and promptly made without complaint. Cleanup was done in a timely manner and to our satisfaction. Having had other construction work done on homes I can honestly say, MGT Carpentry was professional and their work was excellent. I highly recommend them."

FAQs for addition to existing structure building service projects in Port Jefferson Station, 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.
