"What started as a deck rebuild turned into a three season room addition. Matt and his crew were easy to work with, offered some great suggestions to us, and the finished room is more than we hoped for! We loved his suggestion of putting pine on the vaulted ceiling, and the finish work at the bottom on the outside looks great. Matt took care to match our 20 year old siding, and finish the windows and doors to exactly match the others on the house."

"NYC Sewers helped us do hydro-excavation around utility lines in a new development project we did. We also hired them to clean and later maintain dry wells in our strip center that were flooding with heavy rains. Each time they were professional and knowledgeable and their prices were great compared to other companies we contacted."

Subcontractors questions, answered by experts

General contractors typically manage home renovation or build projects that last more than a week and involve various skilled tradespeople. Some examples include building a new home or barn, adding an extension or garage, or carrying out major room remodels involving extensive plumbing, electrical, and structural changes.

The timeline for building a game room depends on the project’s complexity. Converting an existing room may take one to three weeks, while building a new addition or highly customized space can take several months. Factors such as permitting, material lead times, and contractor availability also impact the project schedule.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

While it can be easy to reupholster small items like outdoor cushions or pillows yourself, bigger projects are better left to the professionals. Hiring a professional reupholstery service is the best way to ensure your furniture is properly fixed, especially if you’re working with larger pieces, like couches, or high-end materials, like leather, where mistakes can be costly.
