Post-construction cleaning plays a vital role in preparing newly built or renovated spaces for occupancy. After contractors complete their task, properties are usually left in dust, debris, and materials that can only be cleaned by professionals before they become safe and presentable. This last stage is often provided by cleaning companies hired by builders, developers, and property owners, which makes the post-construction cleaning one of the most demanded services in the sphere of the building industry.
In the case of cleaning companies, making accurate and competitive bids is crucial to the acquisition of contracts and a good reputation. A good bid is not only cost-effective and labor-intensive, but it should also be professional and reliable. Knowledge of the bidding process assists professionals involved in cleaning to achieve maximum profits, achieve client satisfaction, and establish success within a competitive market in the long term.
Understanding Post-Construction Cleaning
Post-construction cleaning is not like normal janitorial work. It is less mechanized, is more equipment-intensive, and attention to detail is required. These are the jobs that normally occur in stages:
- Rough cleaning: Clearing up of big garbage, remains, and heavy dust.
- Light cleaning: Wiping of surfaces, dusting of surfaces, cleaning windows, and fixtures.
- Last-minute cleaning: Floor polishing, washing bathrooms, and making the premises presentable to the residents.
Since the job is more complicated, it has to be reflected in the bid, including the amount of work, effort, and specialized equipment needed. Many contractors now use demolition estimating services alongside construction bids to get accurate cost projections. Similarly, cleaning businesses must follow the same structured approach to ensure accuracy and competitiveness in their post-construction cleaning bids.

Step 1: Conduct a Site Visit
Do not offer a bid on a post-construction cleaning job without going to the location. A physical check-up will enable you to observe the extent of work. During the visit:
- Record the size of the building in square feet.
- Find the kind of surfaces (tile, wood, carpet, glass, etc.).
- Find types of debris (paint splatters, drywall dust, adhesives).
- Determine the need for special equipment (lifts, HEPA filter vacuums).
Visiting the location is not only a way of being precise in pricing but also a way of gaining credibility among potential clients.
Step 2: Calculate Labor Costs
The biggest cost in post-construction cleaning is labor. To calculate:
- Determine the required workforce.
- Time the number by the number of hours needed to perform the job.
- Include overtime or a high salary in case of deadlines.
As an example, when a building of 5,000 square feet needs a group of 4 cleaners who work 20 hours each, then this translates to 80 labor hours. The labor would be $20/hour, and this would be $1600.
It is important to always take into consideration setup, breaks, and other unforeseen delays when computing labor.
Step 3: Factor in Materials and Equipment
Mops and rags are not enough to clean after the construction. Consider the cost of:
- Dense cleaning agents.
- HEPA dust extractors and vacuums.
- Ladders/high surface lifts.
- Protective gear for workers.
- Buckets, trash bags, and disposable supplies.
Consumables are costly, and some of these are reusable. Add a markup of materials in your bid to meet these costs.
Step 4: Add Overhead and Profit
That being said, similar to any company, you should include overhead costs in your bid, such as insurance, licensing, transportation, and administrative expenses. Once all the costs are accounted for, it’s important to add a reasonable profit margin typically between 10% and 30%, depending on market competition and project size. Professional construction estimating services can help ensure these factors are accurately calculated, giving you a clear picture of your true project cost and profitability.
For example:
- Labor: $1,600
- Materials: $300
- Overhead: $200
- Profit (20%): $420
Total Bid: $2,520
Step 5: Understand Industry Pricing
Average price in your area for post-construction cleaning research. Most firms charge based on the square footage, with an average cost of 0.10-0.50 dollars per square foot basis depending on the difficulty.
For instance:
- Simple cleaning of a 2,000-square-foot house can cost as much as $400.
- A high-rise commercial structure, which is covered with glass and specialty surfaces, can cost more than $10,000.
Being aware of the rates in the local market will assist you in remaining competitive and avoiding underpricing your services.

Step 6: Write a Professional Proposal
Your bid must be in the form of a proposal and not as a figure on paper. Include:
- Scope of work Source: List down what is going to be cleaned (windows, floors, baseboards, etc.).
- Timeline: Show the duration of the project.
- Cost breakdown: Present labor, materials, and overhead in an easy-to-understand manner.
- Terms and conditions: Timeline of payment, warranty, and limitation.
A detailed proposal also makes people trust it and minimizes misunderstandings in the future.
Step 7: Build Relationships with Contractors and Developers
It is not just about numbers when it comes to bidding; it is about relationships. Cleaning companies are usually engaged by general contractors and developers regularly. The dependability of service and competitive bids can make you the preferred provider of future projects to them. Long-term clients are secured through networking, going to industry events, and being a professional.
Tips for Submitting a Competitive Bid
Be comprehensive: List all the services you offer to clients to make them know that you are worth it.
Alternative to offer: Have alternatives to offer flexibility (price between basic and deep cleaning).
Highlight experience: Present other successful projects that you have done.
Factor in insurance: Liability insurance is a necessity for many contractors before they award contracts.
Be practical: Do not undervalue in an effort to secure contracts; profitability is what keeps your company afloat.
Common Mistakes to Avoid
- Underestimating time: Post-construction cleaning often takes longer than expected due to heavy dust and debris.
- Forgetting about equipment rental: Lifts, scaffolding, or industrial vacuums can significantly raise costs.
- Not clarifying scope: If you don’t specify what is included, clients may expect more for the same price.
- Overlooking safety requirements: OSHA standards and PPE add costs that must be accounted for.
Why Bidding Correctly Matters
Accurate bidding is not only about the price of the job, it ensures profitability, builds client confidence, and forms the foundation for repeat business. By utilizing construction takeoff services, contractors can prepare detailed and transparent proposals that help them stand out as competent and professional service providers in a highly competitive market.

Conclusion
Bid estimation on the clean-up job after construction should be balanced in terms of accuracy, professionalism, and strategy. With some planning to visit sites, estimate costs of labor and materials, overhead, and an understandable proposal, you are likely to come up with competitive bids that will earn you a contract and a profit.
Your cleaning business can grow to be a reliable service with experience, networking, and consistency with contractors and property owners, so that your business can grow in the long term in the post-construction market.
