G² Glass Bros · New Haven Shoreline, CT
Family-run, 5-star window cleaning for homes and businesses across Greater New Haven. We go beyond the glass — frames and sills included.
One crew, every detail. From a single-story home to a storefront, we clean the whole window — not just the glass.
We lift hard water stains, pollen, grime and oxidation from the outside of every pane — finished streak-free and crystal clear.
Shoes off, surfaces protected. We clean inside glass, tracks and sills with care for your floors, furniture and finishes.
The detail others skip. We wipe down frames and sills so the whole window looks refreshed — not just the glass.
Storefronts and offices that make the right first impression. Early-morning and weekend slots, on a schedule that works for you.
Spot a streak after we leave? We come back and re-clean it — no charge, no debate.
You get a confirmation and we show up when we say. Reliable scheduling our customers actually mention by name.
"Professional and respectful" is in our reviews for a reason. We treat your property like our own.

G² Glass Bros was started by two local cousins with a simple idea: do window cleaning the way you'd want it done at your own home. That means showing up on time, taking our shoes off at the door, and cleaning the whole window — frames and sills, not just the glass.
We're proud that nearly every customer leaves a five-star review and calls us back the next season. That's the only growth strategy we believe in: do great work, and be the kind of people you're glad to have around your home.
"They were professional, responsive, and made the entire process smooth from start to finish. The quality of work was excellent — everything looked perfect when completed. It's hard to find companies that are reliable, honest, and truly care about customer service, but they exceeded expectations. Will definitely use them again!"
"G2 came and serviced my house and did a wonderful job on each window. They're my go-to whenever I need a reliable and consistent service."
"I had pesky water stains that would not budge on my skylight window. These guys came and took care of business. They're definitely getting a call back when it's time for another wash."
