I want to express my greatest thanks for the excellent roofing, siding replacement, ADA hand rail, and concrete work you performed. Kaiser Permanente and PG&E were very pleased with your work.

Useful Info for Lafayette CA

Lafayette, CA was settled almost 10,000 years ago by a branch of the Miwok Indians. When the first Spaniards arrived, they were attracted by the moderate climate and fertile soil and built one of the earliest European settlements.

In 1847, Elam Brown arrived with a convoy of 14 wagons to become one of the first Yankee settlements in what is today Contra Costa County. Not liking how far the closest grist mill was for grinding their grain, Elam built his own steam powered mill. So central was this location that the commercial center of town grew up around the mill.

The discovery of gold in the 1850’s brought a tremendous population explosion to many early California town, and Lafayette was one of them. Mostly a quiet farming village, the end of WWII saw another influx to the local population seeking affordable housing.
