Cheapest ways to get more customers for window & door installers
The cheapest way for a window company to get more customers is almost always to stop losing the ones it already earns — retention and referral cost a fraction of acquisition and are usually unmanaged.

Everything below is ordered by cost per additional customer, cheapest first. None of the first three require a media budget.
That order is not a preference. In this category federal credits and utility rebates change the buyer’s math, and the category’s hard-sell reputation makes restraint a differentiator which means the leaks are worth more than the taps.
Step by step
Ask every existing customer for a referral, systematically
Not a campaign — a habit with a trigger and an owner. Most window company operators get referrals accidentally and have never counted them by source.
Reactivate the people who already bought once
A lapsed customer is the warmest list available and the cheapest to reach. Almost nobody in this category works it deliberately.
Complete and maintain the local business profile
Free, immediate, and roughly half-finished at most competitors. Every field, real photos, accurate hours, correct primary category.
Build a review habit rather than a review campaign
Ask everyone, every time, without incentives. Depth and recency both count, and a steady trickle beats a burst after a good month.
Then, and only then, buy attention
Once the model holds and the free channels are running, paid demand is worth funding — usually starting with incentive-accurate content (25C credits and utility rebates explained honestly).
Common mistakes
Discounting to fill the gap
A discount buys volume once and trains the buyer to wait. For a window company it also resets the price expectation for everyone they tell.
Measuring cost per lead instead of cost per customer
Cheap leads that never convert are the most expensive marketing there is, and they look excellent on a dashboard.
