De Leon Engineering has always provided Foundation Certifications as one of our many services and to date has assisted in closing 1000’s of new purchase loans, refinancing loans, and reverse mortgages.

Since downsizing in 2011, De Leon Engineering now specializes primarily in providing certifications and various engineering reports in 8 Northern California counties, as well as other limited civil engineering consulting services.
