"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."

Water main install, replace or repairs FAQs

Whether you need a permit depends on your local regulations. Always check with your municipality before beginning the installation. Most contractors will handle the permitting process for you.

If your backflow preventer fails, dangerous contaminants can enter your clean water supply, posing serious health risks. You may notice signs like visible leaks, a sudden drop in water pressure, slow drainage, unpleasant odors, or discolored water. If you experience any of these symptoms, contact a professional immediately.

Signs of a failing backflow preventer include visible leaks, a sudden drop in water pressure, sluggish drainage, unpleasant odors, and discolored water. If you notice any of these issues, it's important to have your system inspected by a professional.

You might need a backflow preventer if you have features like irrigation systems, pools, or other water elements that could contaminate your water supply. Commercial and industrial properties are required to have backflow preventers due to higher contamination risks.

A backflow preventer stops water in your main supply from reversing flow and contaminating clean water. A backwater valve is installed in your drainage system to block sewage from backing up during heavy rainfall or overflow. Both devices protect your home but serve different purposes.

The time it takes to install a backflow preventer depends on the type of system. A plumber can typically install a simple backflow preventer, like those for a garden hose or appliance, in less than an hour. Installing a backflow preventer for a complex system can take up to a full day.
