Looking for one of the best insulation companies in California? You've come to the right place! OJ Insulation specializes in insulation for both homes and offices. For over 35 years, we've been helping residents in the Southern CA area maximize energy efficiency and save money.

OJ Insulation opened for business in 1984 in El Monte, California. Our objective was to develop a reputation among local builders and contractors for thorough professionalism in completing commercial and residential insulation projects. For over 35 years, we’ve developed our reputation and are now known as one of the best insulation companies in California.

After 35 years of devotion to all of our customers, we have grown from a small garage into a multi-branch insulation company servicing all construction projects in Southern California – from Ojai to the Mexican border and as far east as Indio and Imperial County.
