Know the Scope Before You Bid
Before giving out a quote, take the time to actually look at the job. Are we talking about a single-story office building or a multi-floor commercial property? There’s a huge difference between the two, and your bid needs to reflect that. Walking the property or reviewing detailed pictures can give you a clear idea of how long the job might take and what kind of tools or crew you’ll need. Never guess—get the full picture first.
Ask the Right Questions
Don’t rush into pricing. Ask how often the cleaning is expected, what hours you’re allowed to work, and if there’s access to water on-site. You should also know whether you’ll be dealing with hard water stains, bird droppings, or heavy dust—some spots take more effort than others. The more information you gather, the better your bid will fit the client’s needs.
Factor in Labor and Time
Time is money, and you have to figure out how long the job will realistically take. If you’re working with a crew, think about how many people are needed and how many hours each of them will work. Factor in breaks, setup, and wrap-up time. The more accurate you are here, the less chance you’ll undercharge or overbook yourself.
Don’t Forget Safety Requirements
Working on commercial buildings can come with safety risks. If ladders, scaffolding, or lifts are involved, your bid should reflect the cost of those safety measures. Depending on the height of the building, OSHA rules may apply, and that could impact what equipment is needed and how many workers should be present.
Material Costs Matter Too
Window cleaning isn’t just about labor. There are supplies to think about—cleaning solution, squeegees, extension poles, and more. For higher buildings, you may need specialty gear like water-fed poles or lift rentals. These materials wear down or run out, so it’s smart to include a bit of cushion in your bid to cover those.
Consider Frequency in Pricing
Are you quoting for a one-time clean or a recurring service? This changes the game. A monthly or bi-weekly job might allow you to offer a slightly lower rate per visit, because you’re building in regular business. If it’s a once-a-year situation, your pricing should reflect the deeper cleaning it will likely require.
Know Your Competitors Without Copying Them
It’s good to be aware of what others are charging, but don’t race to the bottom just to win a bid. If your quality, reliability, and customer service stand out, you can charge a fair rate without needing to be the cheapest option. Clients often want a good deal, but they also care about results—and dependability.
Present a Clear, Professional Proposal
Your bid should be written clearly. Break it down into labor, materials, and total estimated hours. Offer a simple description of what’s included, like interior and exterior cleaning, frames, and sills. Avoid vague language and show that you’ve paid attention to the details of their property. A professional bid builds trust.
Be Transparent With Terms
Mention your payment terms, how long the bid is valid, and whether you’re offering a trial period or contract. Being upfront avoids surprises for both you and the client. It also protects you if something changes down the line.
Follow Up Without Being Pushy
After you’ve submitted your bid, follow up in a few days. Ask if they have any questions or need clarification. Don’t spam them with messages, but do show you’re interested. Clients often appreciate the effort, especially when they’re trying to compare multiple proposals.
Keep Improving With Every Bid
The more bids you write, the better you’ll get. Over time, you’ll develop a solid system and learn what works for your business. Review past jobs to see where you guessed right—or wrong—on time and cost. Use that info to make smarter bids next time around.
Final Thought
Bidding for commercial window cleaning services isn’t just about giving a number. It’s about showing the client you understand their property, their needs, and that you’re the right person for the job. Be honest about your pricing, back it up with solid reasoning, and keep things professional but friendly. Every bid is a chance to build your reputation—so take it seriously, even if you don’t win every time.
