Frequently Asked

Answers before
you call.

Cedar or aluminum?

Cedar looks warm but needs staining. Aluminum is zero-maintenance and now looks great.

Louvered — worth it?

Yes, if you want real rain protection and sun control on demand.

Do pergolas need a permit?

Freestanding and attached structures usually require one in Suffolk County towns. We file it.

What materials do you use?

Cedar, western red timber, vinyl, and aluminum louvered systems, set on masonry piers or footings.

How long does install take?

Most pergolas are set in 2–5 working days once footings cure.
