The biggest mistake remodelers make with reviews is treating it as a one-time task - asking a batch of past clients all at once, then going quiet for months. Google and homeowners both favor recency, so a steady trickle beats a big spike followed by silence.
The best time to ask is the day a job finishes, while the homeowner is happiest and the work is freshest in mind. A simple text with a direct link to leave a review, sent automatically the day after project completion, removes the friction that causes most requests to get forgotten.
Make it easy: a direct link (not "just search us on Google"), a short, friendly message, and - where appropriate - a gentle follow-up a few days later if they haven't responded. Automating this single step is one of the highest-leverage, lowest-effort marketing changes a remodeler can make.
