How to Price Window Cleaning as an Add-On Service for Your Cleaning Business

Window cleaning is one of the most requested extras in residential and light commercial cleaning. Clients notice clean glass immediately, and many of them would happily pay for it if you offered. The challenge is pricing it so you make money without underestimating the time, equipment, and safety risks involved.

This guide explains how to add window cleaning to your cleaning business, choose a pricing method, scope the job, and know when to refer out or subcontract.

Why Window Cleaning Makes a Good Add-On

Window cleaning fits naturally with residential cleaning, move-out cleaning, post-construction cleaning, and small offices. You are already on site, the client already trusts you, and clean windows make the rest of your work look better. Offering it can raise your average ticket and give clients a reason to book you instead of a competitor who only cleans the inside of the house.

It also works as a seasonal promotion. Many clients think about windows in spring and fall, before holidays, or when they are preparing to sell a home.

Interior vs. Exterior Windows

The biggest decision is whether you clean interior glass, exterior glass, or both.

• Interior windows are the easiest add-on. Your crew can clean them with standard tools while inside, and the risk is low if they stay on the floor or use a short step stool safely.
• Ground-floor exterior windows are manageable with a squeegee, scrubber, and an extension pole.
• Upper-floor exterior windows involve ladders or water-fed pole systems, higher liability, and often different insurance considerations.

Many cleaning companies start with interior and ground-floor windows only. Before offering anything higher, check with your insurance agent about coverage for ladder work and heights, and train your crew on safe practices. For high-rise and commercial storefront work, a dedicated window cleaning company is usually the right partner.

Pricing Methods for Window Cleaning

There are three common ways to price windows. Choose one and use it consistently so your quotes are fast and predictable.

1. Per pane or per window. Count windows and charge a set amount for each, with different rates for standard, large, and specialty windows. This is easy for clients to understand.
2. Per hour. Estimate how long the job will take and charge your hourly rate. This works for irregular jobs but can make clients nervous about the final cost.
3. Flat package price. Offer a package such as "all interior windows" or "interior and ground-floor exterior" for a set price based on home size. This is simple to sell alongside your regular service.

Whatever method you choose, base it on your own timing. Time your crew on a few typical homes and windows so you know how long each type really takes, then build in your labor cost, supplies, overhead, and margin. Local market rates vary widely, so check what window specialists in your area charge before setting prices.

What Affects the Price

Two homes with the same number of windows can take very different amounts of time. Factors to account for:

• Window type: divided panes and French doors take longer than large single panes.
• Screens: removing, cleaning, and reinstalling screens adds time.
• Tracks and sills: cleaning dirty tracks can take as long as cleaning the glass.
• Access: furniture, window treatments, landscaping, and steep grades.
• Condition: hard water spots, paint overspray, or construction residue may need special treatment and caution to avoid scratching.
• Height and ladder work, if you offer it.

List these as separate options on your quote, such as "screen cleaning" or "track detailing," so clients can choose what they want.

Equipment You Need to Start

Basic window cleaning does not require a big investment. A starter kit typically includes a quality squeegee, a strip washer or scrubber, microfiber cloths, a bucket, a mild window cleaning solution, a scraper used carefully on suitable glass, and an extension pole. Add drop cloths or towels to protect sills and floors.

Train your team on technique. Streak-free glass comes from practice, clean tools, and the right solution, not more product. Caution your crew about scraping, since some glass coatings and tempered glass can scratch.

How to Present Window Cleaning to Clients

Present windows as a clear option rather than a surprise. Ideas that work well:

• Include a window line on every residential quote with a simple price or package.
• Offer windows with deep cleans and move-out cleans, where clients expect a more complete job.
• Run a spring or fall window promotion for recurring clients.
• Suggest windows before the holidays when clients are preparing for guests.

Show before-and-after photos with permission and keep the conversation focused on how the home will look and feel, not the technical process.

When to Refer Out or Subcontract

Not every window job is right for your team. Multi-story exteriors, skylights, commercial storefronts on a recurring route, and buildings that need lifts or rope access are usually better handled by a window specialist. Building a referral relationship with a local window company can benefit both businesses: you send them high work, and they send you interior cleaning requests.

If you subcontract, put the scope, pricing, insurance requirements, and quality expectations in writing. The client sees your company name, so you are responsible for the result.

Bundling Windows With Recurring Service

One-time window jobs are useful, but recurring window service is where the add-on really pays off. Offer recurring clients a scheduled window cleaning every few months, priced as a package and added to their regular invoice. Because you already know the home, quoting is fast and the job becomes predictable for your team. You can also rotate rooms, cleaning interior windows in a few rooms at each regular visit so the whole house stays fresh without a long one-time appointment. Put the schedule on your calendar so the reminder comes from you, not the client.

Protecting Your Margin

Window add-ons can lose money if you guess. Track actual time against your quote for the first several jobs and adjust your pricing as you learn. Set a minimum charge for small window jobs so a short visit still covers travel and setup. Revisit your rates once a year alongside your other services.
