Frequently Asked Questions

Is Bau licensed and insured?

Yes. We are licensed and insured, with general liability, auto, and workers’ compensation coverage. We review project insurance requirements with our broker to arrange applicable coverage and endorsements. Contact us to discuss current documentation and the requirements for your project.

How long does a renovation take?

The scope, design, permits, and material deliveries affect the timeline. We prepare a construction schedule for your project, update it as the work progresses, and let you know when decisions are needed.

Do you handle permits and approvals?

Yes. We coordinate the required documents with your architect, engineer, or other licensed professional, submit permit applications, and work with the reviewing agencies. We obtain the required approvals before starting that work.

What areas do you serve?

We work in Manhattan, Brooklyn, Queens, the Bronx, Westchester, Rockland, and Orange counties, plus Bergen, Essex, and Hudson counties in northern New Jersey. Contact us about your location and the work you have in mind.

I’m not sure what my project will cost. How do you help build a budget?

We discuss the home you want to create and what you expect to spend, then compare layout and finish options. We explain how those choices affect the cost and prepare an estimate with allowances for finishes you wish to select. You do not need a settled budget to contact us.

Can you work with our architect or designer?

Yes. We work with your architect, designer, and other project professionals. If you need one, we can introduce design professionals we have worked with. They prepare the design, and we coordinate it with the construction.

When should I contact Bau?

You can contact us at any stage. Call or email us about a room you want to improve, a complete home renovation, or plans you already have.
