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. The planning and execution of the job was very evident and the workmanship cannot be matched. I have and will continue to recommend Airtight Construction.

Useful Info for Danville CA

Danville, CA is not really a city, but is officially referred to as a town. Frequently called the heart of the San Ramon Valley, Danville was originally settled as part of the Mission San Jose’s farmland and grazing for their farm animals. Originally a farming community, the first crops grown included grains, fruits and nuts. The railroad arrived in 1891 and presented Danville the opportunity to not only export their crops but import new settlers. The arrival of a significant population created a demand for residential housing, schools and churches.

Danville today is famous for how many of its earliest buildings survived and can be seen today. Danville was not incorporated until 1982, and is regarded as one of the most prosperous communities in the entire San Francisco Bay Area. Danville is home to many very fine shops and restaurants, and is one of the wealthiest zip codes in the entire United States.
