Custom Signs in Groton — Your Questions Answered
Signs We've Built for Groton Businesses
ROUTE 1 — GROTON
Illuminated Channel Letters
A multi-tenant retail plaza near Long Hill Road needed three storefront sign packages installed in the same week. We coordinated electrical with the landlord, pulled permits with the Town of Groton, and had all three lit by the weekend.
POQUONNOCK ROAD
Restaurant Monument Sign
A new restaurant near the Submarine Base needed a high-visibility monument sign that holds up to constant traffic spray and coastal humidity. CNC-routed PVC with aluminum reinforcement and a warm LED wash — visible day and night from both directions.
THAMES RIVER MARINAS
Boat Lettering & Transom Graphics
Two repeat marine clients at Groton-area marinas had us re-letter their vessels for the season. 3M marine-grade vinyl, gold leaf accents, installed dockside in a single morning.
What Groton Owners Say
"We called three local sign shops. WaterMark was the only one who actually drove out to look at the building before quoting. That told us everything we needed to know."
— Plaza tenant, Route 1 Groton
"Our boat lettering still looks brand new after two full seasons in salt water. Worth every penny — not even close to what we'd been getting from chain shops."
— Vessel owner, Thames River marina
