"The work went very well. Lou is very knowledgeable, professional and easy to work with. He inspected my house thoroughly and explained my concerns in great details. He went beyond and explained some of the common non-structural issues on an old house. He also suggested on the proper ways to fix them.

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation 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."

Structural Engineering questions, answered by experts

In Long Island, structural engineering upgrades—such as foundation reinforcement or hurricane-resistant features—can significantly boost your home’s value and attract buyers. Homes with documented wind and flood resistance often command higher prices. Energy-efficient improvements add further appeal. Keep all engineering reports, permits, and warranties organized, as these reassure buyers and may help you secure lower insurance premiums, making your property more marketable.

Helpful?

After finishing structural engineering work in Long Island, promptly schedule a final inspection with your local building department and submit all necessary completion paperwork within 90 days. Update your homeowner’s insurance to reflect the improvements and store all permits, drawings, and inspection reports together. For coastal properties, arrange a wind resistance check after storm season and monitor for foundation settlement, especially in areas with clay-rich soil.

Helpful?

In Long Island, begin spring by checking your foundation for cracks caused by freeze-thaw cycles. During summer, review hurricane preparedness by inspecting roof ties and deck fasteners. In fall, look for storm or water damage and examine chimney supports. Winter requires monitoring snow loads and watching for ice dams. For homes near the coast, quarterly inspections help catch salt air corrosion and storm-related issues early.

Helpful?

For a smooth project in Long Island, start by reviewing local building codes, zoning, and flood zone requirements. Assemble a team that includes a structural engineer, architect, and skilled contractor. Apply for permits using detailed engineered drawings, and plan work outside hurricane season to avoid weather delays. Mark underground utilities before excavation, communicate with neighbors, and document progress with photos and inspection records for future reference.

Helpful?

For Long Island projects, use concrete rated at least 4,000 PSI with air entrainment for freeze-thaw protection, and epoxy-coated rebar to guard against coastal corrosion. Opt for hot-dip galvanized steel near the shoreline and hurricane-rated connectors for framing. Engineered lumber and waterproof membranes are essential for high water tables. Always confirm your materials meet local climate demands and building code standards.
