Local FAQs

Home Extensions questions in New York City

How much does Home Extensions cost in New York City, NYC?

There is no single price that fits every property. The main cost factors include size and extent of the work, access, staging and protection requirements, condition of the existing substrate, demolition, disposal and preparation. NY1 provides a written estimate based on the actual scope.

How long does Home Extensions take in New York City, NYC?

Timing depends on the size of the work, access, material availability, curing or drying time where applicable, and whether related repairs are discovered. NY1 explains the expected sequence before work begins.

Can NY1 look at photos before scheduling a visit?

Yes. Call or text 631-588-7400 with the property location and clear photos. Photos can help identify the likely scope, although some conditions still require an on-site evaluation.

Does NY1 work on occupied properties?

Yes. Protection, dust or debris control, access and sequencing are planned around the actual project and the people using the property.

Do I need permits or building approval for this work?

It depends on the exact scope, building type and whether structural, exterior or regulated work is involved. NY1 can identify when approvals or permit coordination should be part of the project planning.

Can NY1 coordinate related trades on the same project?

Yes. NY1 is a general contractor, so projects that touch framing, roofing, masonry, windows, finishes or reconstruction can be coordinated as one overall scope when appropriate.

Have a project or a problem that needs a contractor?

Call NY1 24/7 or send photos to start the conversation.
