Digital marketing for window companies: research pages for a slow decision, follow up for the quotes that wait, and three US rules

Digital marketing for a window company is built around one expensive, slow decision: a homeowner replacing several windows at once. The work that pays is a website that explains products, materials and the quote process clearly, a Google Business Profile full of installed-job photos and reviews, search ads on replacement and repair searches, and a follow up system for the many quotes that do not close on the first visit. Three US rules shape the plan: the EPA lead rule for work on homes built before 1978, the FTC's cooling-off rule for sales made in the customer's home, and Meta's housing ad category, which can limit how home improvement ads are targeted.

Know which window business you are marketing

"Window company" covers several different businesses, and each needs its own pages and ads:

• Replacement windows for existing homes, the largest consumer market.
• Window repair: broken glass, failed seals, foggy double glazing, hardware.
• New construction, sold to builders rather than homeowners.
• Doors, patio doors and skylights, often sold alongside.

Window cleaning is a different trade altogether, with its own route-based marketing, covered in our page on window cleaning marketing.

What to measure

• Appointment requests for an in-home or virtual quote, by source.
• Appointments held: many get cancelled, so track this separately.
• Close rate and average project value.
• Cost per sale for each channel.

A channel that books many appointments but few sales is often attracting price shoppers. Read the search terms that produced those leads.

A website that answers the research questions

Homeowners spend weeks reading before they let a salesperson in. Answer what they are trying to work out:

• Material pages: vinyl, wood, fibreglass, aluminium, composite. What each costs to maintain and how long it lasts in your climate.
• Style pages: double-hung, casement, sliding, bay and bow, picture windows, with photos of your own installs.
• Energy performance: explain the labels and ratings on the products you sell, in plain words, and only claim what the manufacturer's documents support.
• The process: measure, order, lead time, installation day, cleanup, warranty registration.
• Pricing approach: what drives the price. If you publish ranges, say what is included.
• Financing, if you offer it, with terms stated accurately.

Offer both an in-home quote and a virtual or photo-based estimate. Some buyers will not book a home visit until they trust you.

The Google Business Profile and reviews

• Choose the most accurate primary category and add replacement, repair, doors and any other services you offer.
• If you have a showroom, show it, with hours that match when it is staffed.
• Post photos of finished installs every week, with the homeowner's permission.
• Ask every customer for a review after installation. Google's review policy forbids incentives and forbids asking only happy customers.

The FTC's review rule, 16 CFR 465.4, bars rewarding reviews of a particular sentiment, and 465.5 requires a disclosure when managers or staff write reviews or testimonials.

Paid search and Local Services Ads

Google's Local Services Ads list "Window repair services" as an eligible US category (checked 21 October 2026). That fits repair work. For replacement projects, standard search ads give you control:

• Separate campaigns for replacement, repair and doors, each sending people to the matching page.
• Bid on product and material searches with your service area, such as "vinyl replacement windows" plus town names.
• Negative keywords for "DIY", "how to install", "jobs", "window cleaning", car window and window film searches unless you offer them.
• Track sales, not just form fills. Import closed sales back into the ad account when you can.

Facebook and Instagram ads

Before and after photos of a whole house front work well on social media. Check one rule first. Meta's Special Ad Categories page lists "housing repairs" within its housing category. If Meta classifies your window ads as housing ads, then for advertisers in or reaching the US, and those reaching Canada and some European countries, age, gender, ZIP code, exclusions, lookalike audiences and saved audiences are limited or unavailable. Plan creative that targets a city or radius and qualifies the buyer through the picture and the offer.

Older homes: the EPA lead rule

Window replacement is one of the activities the EPA names under its lead Renovation, Repair and Painting Rule, which covers homes and child-occupied facilities built before 1978. The EPA's contractor page (read 21 October 2026) says firms "cannot advertise or perform renovation activities covered by the RRP Rule" in those buildings without firm certification. The regulation, 40 CFR 745.81(a)(2)(ii), uses the words "perform, offer, or claim to perform". If you replace windows in older homes, get certified before you advertise it, and say so on your site.

In-home sales: the FTC cooling-off rule

Most replacement window sales are signed at the kitchen table. The FTC's rule on sales made at home, 16 CFR Part 429, covers sales of $25 or more made at the buyer's residence, "including those in response to or following an invitation by the buyer". The seller must give the buyer a receipt or contract with a statement that the buyer may cancel "at any time prior to midnight of the third business day after the date of this transaction", plus a notice of cancellation.

For marketing, this means two things. Say plainly in your ads and on your site that there is no pressure to sign on the day. And if you ever run a "sign today" price, the buyer's right to cancel still applies to it, so train sales staff to explain that. This is general information, not legal advice.

Follow up: where most of the sales are

Many quotes do not close at the first visit. A follow up sequence makes the difference:

• A thank you the same day, with the written quote and the answers to any questions raised.
• A check-in a week later, with photos of a similar job.
• A seasonal note months later for those who postponed.

Commercial emails need a working opt-out and a valid postal address under the CAN-SPAM Act (15 USC 7704).

Questions about digital marketing for window companies

What is the best marketing channel for a window replacement company?

Search ads on replacement and material searches, backed by a strong Google Business Profile and a website that answers research questions, usually produce the most appointments. Follow up turns those into sales.

Can window companies use Google Local Services Ads?

"Window repair services" is an eligible US category on Google's Local Services Ads page, read 21 October 2026. Replacement-focused companies usually rely on standard search ads as well.

Do I need lead-safe certification to advertise window replacement?

For homes built before 1978, yes. The EPA names window replacement as covered work and says firms cannot advertise it without RRP certification.

Does the three-day cancellation rule apply to window sales?

For sales of $25 or more signed at the buyer's home, the FTC's cooling-off rule gives the buyer until midnight of the third business day to cancel, even when the buyer invited the salesperson.

Are Facebook ads for window companies restricted?

They can be. Meta lists housing repairs in its housing category, which limits age, gender and ZIP code targeting in the US and some other countries.

The research question a buyer now asks out loud

Before inviting anyone over, homeowners now ask ChatGPT or Gemini which window companies near them are reputable and whether vinyl or fibreglass suits their climate. The answer names local firms and leans on whatever product pages, reviews and articles it can find about them. A company that explains its materials and process clearly gives the assistant better material to work with. Checking whether your company is the one named is what AI Knows Us, part of a newer category of service, does.
