Josué (Josh) Rosado is the President of J R Construction-Sol Solutions, Inc. Sol Solutions is a full service home performance professional energy auditing firm serving the San Francisco Northern Bay Area with headquarters in Napa, California.

Our energy audits use diagnostic tools to pinpoint and analyze your home's energy efficiency and indoor air quality. We evaluate your home's insulation, air leakage, heating and cooling equipment, appliances and lighting and provide a Home Energy Performance Report outlining the most cost-effective energy improvements for your home, your most valuable financial asset. Included in our analysis is a thorough combustion safety check for any natural gas leaks and any carbon monoxide (CO) problems that might be present in order to increase your home's safety and comfort.

The Home Energy Performance Report will give your home an Energy Rating Score that is certified through CalCERTS and the California Energy Commision (CEC). When you complete the recommended retrofits, this energy rating will have positive benefit to you by adding resale value to your energy efficient home.

Sol Solutions partners with ENERGY UPGRADE CA (EUC) and the Sonoma County Energy Independence Program (SCEIP) as a certified building contractor and HERS Rater. We will review and assess your home's energy performance and provide recommendations on how to improve your home's efficiency through a written report. We will guide and inform you of eligible energy efficiency rebates and tax credits in your area.

Sol Solutions is a licensed, insured and bonded contractor. We are a CalCERTS certified Home Energy Rating System (HERS) Rater and are certified with the Building Performance Institute (BPI) as a Building Analyst and Envelope Professional. We bring over twenty years of construction experience and building science knowledge to assist you in improving your home's energy needs. 

Our goal is to improve the safety of your home bringing you satisfaction and comfort as well as sustainability, and most importantly real financial savings to enhance your quality of life.
