How much should you tip your hardwood floor installer?

When tipping a hardwood floor installer, a common guideline is to give between 10% to 20% of the total installation cost, depending on the quality of the work and your satisfaction. If the installer goes above and beyond, such as completing the job efficiently or providing Excellent customer service, you might consider tipping on the higher end. Alternatively, if you're not comfortable with cash tips, a positive review or referral can also be a meaningful way to show appreciation.
