Our Story
Built by a Long Islander,
for Long Islanders.
Tom Westbrook started Long Island Sunroom Co. in 2011 after building his own sunroom and realizing nobody on Long Island specialized in them. General contractors treated sunrooms as an afterthought. Tom thought they deserved their own crew.
15 years and 580+ projects later, we're still the only company on the island that does nothing but sunrooms, screen rooms, and patio enclosures. That focus means we've solved every problem a Long Island sunroom can have — salt air corrosion, nor'easter wind loads, sandy soil drainage, colonial roofline integration, all of it.

How We Build Sunrooms on Long Island
One trade, one focus
We don't do kitchens, bathrooms, decks, or roofs. Every dollar of investment, every hour of training, and every lesson learned goes into building better sunrooms.
Same crew, every time
No subcontractors. Our 14-person team has worked together for years. When Tom's crew shows up on Monday, the same faces are there on Friday.
Honest quotes, no change orders
We measure, we price, we build. If we missed something in the estimate, that's on us, not on your invoice.
LI weather tested
Every joint, seal, and fastener is chosen for salt air, humidity, wind-driven rain, and freeze-thaw cycles. We've been through enough nor'easters to know what fails and what holds.
