The quick verdict
Mailed cleaning postcards (Clean Launch) run $30-$120 loaded CAC per booked bundle at $1/postcard. Cold Facebook ads for residential exterior cleaning run $200-$600 CAC — too thin against a $500-$3,500 average bundle ticket. The structural issue is intent: homeowners don't browse Facebook looking for soft washing, and a stock-photo before/after of someone else's house doesn't trigger personal recognition. A postcard with their own house rendered clean does.

Why Facebook is structurally weak for cleaning
- Low ticket = no room for retargeting waste. A $500-$3,500 bundle can't absorb the $80-$200 of impression spam Facebook needs to find a buyer. Pool builders get away with this at $40K+ tickets. Cleaning can't.
- The audience isn't searching. Cleaning intent surfaces when the homeowner physically notices the dirt — pollen on siding, algae streaks on the roof, mildew on the deck. Facebook's feed has no signal for that moment.
- Stock before/afters don't trigger. Generic photos of "a clean house" land flat. Homeowners need to see their own house clean to feel the loss of the dirty current state. Mail does this; Facebook can't.
- Seasonal demand collides with FB's learning phase. Cleaning surges post-pollen (April-June) and pre-holiday (October-November). Facebook's algorithm needs 14-30 days to optimize. By the time it learns, the surge is half over. Mail hits the mailbox in 5-7 days at full effectiveness.
Where Facebook fits in cleaning marketing
Retargeting + warm follow-up
Two lanes where Facebook earns its keep:
- Retargeting scanners ($100-$400/mo): Anyone who scans a Clean Launch postcard or visits the customer portal enters a 14-day retargeting flow. Show recurring-annual savings math, bundle breakdowns, before/after of nearby completed jobs. CAC: $40-$120 (comparable to mail).
- Geographic awareness pre-mail ($50-$200/week): Run light Facebook ads in the same zip codes you're mailing for 7-14 days. Homeowners who see the brand twice (feed + mail) book at materially higher rates.
