About Us


The Buchanan name is distinct and well known to all who have resided in the central and eastern sections of Contra Costa County over the past 100 years.

Frank Buchanan the founder began the company in the early 1960’s dedicated to service, low prices and quality workmanship.  Vince Buchanan has carried on the same 50 year old values and ethics since taking control in 1978.  The strong family traditions have carried on with his wife Heidi Buchanan, & our outstanding administrative and installation teams.  We have seen significant growth and take great pride in serving our community. 

Today the family approach to honesty and fairness in business has expanded the company to include all of Contra Costa County and major portions of Alameda Counties as well.

We are dedicated to keeping all of our customers satisfied and confident in our services.  Over 75% of our business is based on referrals and loyal customers.
