Hiring a Quality Contractor
Hiring a contractor can be difficult, whether you are building a house or just looking for someone to repair or refurbish something.  Not all contractors are the same.  Here are some tips we feel will help you select the right contractor and will also tell you a bit more about our work ethics.


Tri-City Acoustics, Inc and Tri-City Insulation is a licensed contractor in good standing with the California State Contractor's License Board.  We have a classification C-2 license for Insulation and Acoustical.  Our license number is 537859.  To check the status of a contractor's license you can check online at or by calling (800) 321-CSLB (2752)
We have our workers compensation insurance with the STATE COMPENSATION INSURANCE FUND - Contractors who employ people are required by the state law to have this insurance.  Ask for proof of insurance as it relieves exposure to a claim on your policy.
Feel free to ask us for proof of our liability insurance.  It is important to select a contractor who elects to have this coverage.  Liability insurance insures any damages that could happen in regards to an installation.
Our contractor's license bond is with WESTERN SURETY COMPANY - Licensed contractors are required to have a contractor's license bond of $12,500.  This bond is written to cover an project the contractor agrees to perform.
We have city business licenses not only in Redlands, but in many of the other Southern California cities where we transact business.
Come and visit our office location.  It is important to verify the Contractor's place of business and telephone to make sure they are a legitimate company.
Tri-City Acoustics, Inc. has been owned and operated by Ron and Joyce Jeffrey for over 20 years.  Longevity and financial stability are significant factors when looking for a contractor.  You want to make sure the contractor that you hire won't be here today and gone tomorrow.  This is important for product and work guarantees.  Also, you want to be sure they are capable of paying their suppliers and employees to avoid liens on your property.
We are independent and locally owned - Personal service and quality are much more likely from a "Hometown" contractor than a large mass production conglomerate.
We believe in "Word of Mouth Advertising" - Most of our business in obtained by word of mouth.  You are more likely to get an excellent job from a referral than by an ad or contractor lead directory.
