Kenneth Lynch & Sons is located in Wilton, CT. We are an industry leader in providing site furnishings including statuary and fountains in cast stone, lead and bronze, weathervanes, sundials, park benches and topiary.
Statuary: Kenneth Lynch & Sons produces thousands of ornamental products from cast stone, Lead and Bronze, such as Garden Statuary.
Animal Statuary: Our lead products are made of 99.5 percent pure lead. Where necessary they are reinforced with brass, bronze or stainless steel to give them the strength that lead does not have.
All "Stone" products are actually "cast stone" which is a concrete product.
Topiary: Made with a stainless steel frame and vinyl coated wire with stainless steel wire and hog rings for fasteners. The stainless steel is then painted green.
Fountains & shells, bird baths, raintrees, borders, cisterns and rosettes, planters, urns and finials, pedestals, oriental pieces, masks & plaques,
Sundials and Directional Markers: Made of bronze, lead, cast stone or iron, are meant to be ornaments. Within the limits of practicality we try to make our larger sundials reasonably accurate.
Weathervanes: Constructed of non-ferrous materials - copper, bronze, aluminum, & stainless steel.
Benches: Wooden bench seats are made of Ipe (Tabebuia) wood. The Ipe is naturally antifungal, very dense and very hard. Iron castings are of break resistant Ductile Iron. Wrought Iron benches are hand crafted. Cast stone benches are made in rubber or fiberglass molds.
