- Find a Comparable Quote: If a competitor offers the same service under the same conditions, with the same equipment, workmanship, and process, bring it to Doornbos for a win-win. NOTE: It must be an official quote with all the details laid out.
- Show Us the Quote: Bring the competitor’s quote to us. We’ll review it to make sure it matches the scope of our service.
- We Match the Price: If everything matches up, we’ll refund the difference plus $250. You get the same top-quality service from Doornbos at a price you found elsewhere, plus $250 for your trouble. (SEE A DOORNBOS REPRESENTATIVE FOR FULL DETAILS.)
