How to Bid Window Cleaning Jobs: A Contractor’s Guide to Pricing
Struggling with bidding? Learn how to bid window cleaning jobs accurately using three proven methods to ensure you never underquote a project again.
Choosing the Right Bidding Method for Your Business
Knowing how to bid window cleaning jobs correctly is the difference between a thriving business and one that barely breaks even. The most common methods include the 'piece rate' (per window), the 'hourly rate' (estimating time), and the 'square foot' method for large commercial buildings. Most residential pros prefer the piece rate for its simplicity and transparency.
The Pre-Bid Inspection Checklist
Before you commit to a price, you must perform a thorough site walk-through. Look for hard water stains, construction debris (like paint or silicone), and accessibility issues like tall bushes or steep terrain. These 'hidden' factors are why learning how to bid window cleaning jobs requires a keen eye for detail before the squeegee ever hits the glass.
Calculating Your Profit Margins and Overhead
Calculate your overhead—including gas, insurance, and equipment wear—to find your minimum 'trip fee.' If you bid a job at $150 but it takes three hours and $40 in expenses, your profit margin might be thinner than you think. Aim for a gross margin of at least 50-60% on labor-intensive residential projects.
Presenting Your Bid to the Client
Many roof and window contractors fail because they give verbal 'ballpark' prices that lead to disputes. When you know how to bid window cleaning jobs, you know that a written quote is a legal safeguard. Professional contractors use WinkScope to create detailed bids that outline exactly what is included, such as screen cleaning or track wiping, to prevent scope creep.
Closing the Deal After Sending the Quote
Don't let your bid sit in an inbox. Follow up within 24-48 hours if you haven't heard back. Sometimes a simple 'Just checking in on the window cleaning estimate I sent' is all it takes to trigger a booking. Consistency in your bidding and follow-up process is what builds a reputable brand in the service industry.
