Concrete Sealing: How to Price and Sell It as an Add-On

How much should you charge per square foot for concrete sealing?

Charge $0.75 to $1.25 per square foot for concrete sealing under normal residential conditions. Keep cleaning separate, because washing and sealing require different labor, materials, equipment, and return trips.

A wide, open driveway with clean edges belongs near the lower half of the range. Small patios, divided walkways, rough surfaces, and areas requiring careful masking belong near the upper half.

Do not pick one universal rate and force every property into it. Build a base rate for straightforward work, then adjust for preparation, layout, product use, access, and risk.

Start with an accurate measurement of every section receiving sealer. Do not use the home's square footage or trust a customer's guess. Separate the driveway, walkways, patio, porch, and pool deck so either party can remove one area without rebuilding the quote.

The table below gives working ranges for common scopes. These are quoting ranges, not a promise that every surface can be sealed at the same rate.

How do you build a concrete sealing price that protects your margin?

Build the quote from surface area, preparation, product, labor, overhead, and profit. A square-foot rate is useful only when it pays for every part of the scope.

First, calculate the direct product cost for the measured area using the manufacturer's stated coverage for that surface and application. Porous or rough concrete can consume more material than a smooth slab, so do not assume every gallon stretches equally.

Next, estimate labor for setup, cleaning, rinsing, drying checks, masking, application, cleanup, and any required return. Include drive time, loading, unloading, and customer communication. Those hours are real even when the spray time looks short.

Then add overhead. Vehicle expense, equipment wear, card fees, quoting time, insurance, and callbacks do not disappear because sealing is an add-on. Insureon reports that general liability insurance for pressure washing companies averages $895 per year. That does not set your rate, but it shows why pricing only labor and product leaves bills uncovered.

Finally, add profit instead of treating whatever remains as profit. Run the finished number through the Pressure Washing Pricing Calculator, then compare the result with your established square-foot range.

You can use flat rates for simple packages, but calculate them from measured area first. The guide to Per Square Foot vs Flat Rate Pricing for Pressure Washing explains when each presentation works better.

What moves a concrete sealing price up or down?

Preparation, surface condition, layout, access, and coating requirements move the price most. Charge for the actual work instead of treating every gray slab as the same job.

Heavy organic buildup raises the cleaning time. Oil marks, rust-colored staining, paint, gum, tire marks, or other discoloration may require separate treatment, and results should never be guaranteed when the surface condition makes full removal uncertain.

Existing coating is another major variable. If a surface has old sealer, determine whether your planned product and process are suitable before quoting. Stripping an existing coating is not standard cleaning and should not be buried inside a normal sealing rate.

Layout matters too. A 1,000-square-foot open driveway is faster to mask and coat than the same area spread across steps, narrow walks, borders, and several patios. Protecting siding, doors, landscaping, metal, and adjacent finishes adds labor.

Access can push the rate higher when you must carry equipment through a home, work behind locked gates, manage steep grades, or keep sections open for occupants. Scheduling constraints also matter when the property cannot remain clear for your planned process.

Extra coats or separate application stages should be explicit line items. Never promise a coat count or return-to-service time without following the product instructions and accounting for weather and surface conditions.

Runoff and wastewater handling can affect the cleaning portion of the job. Review the EPA NPDES program and the requirements that apply where you operate instead of assuming wash water can enter a storm drain.

Should concrete cleaning and sealing be separate line items?

Yes, show cleaning and sealing as separate line items on the same estimate. This keeps the add-on easy to understand and prevents the sealer price from looking inflated.

A clean quote might list driveway cleaning at $0.20 to $0.55 per square foot, then concrete sealing at $0.75 to $1.25 per square foot. Add stain treatment, repairs, coating removal, or extra application stages below those lines when needed.

Separate pricing also protects you when the customer wants cleaning now and sealing later. You can remove the sealing line without cutting the washing price or arguing about what was included.

Use the same measured area for both services only when the full surface receives both. If the customer wants the driveway cleaned but only the patio sealed, show the correct quantity beside each item.

For a deeper breakdown of the first service, see driveway and concrete cleaning prices. Cleaning is required preparation for many sealing jobs, but it is still a service with its own setup, production time, and risk.

What minimum should you set for concrete sealing?

A practical concrete sealing minimum is about $350 to $500. Set your exact minimum from your mobilization time, product requirements, labor floor, and overhead.

Small jobs can be deceptive. A 150-square-foot patio may require travel, unloading, cleaning, drying coordination, masking, application, cleanup, and customer instructions. The application area shrinks, but most of the job cycle remains.

Use one minimum for sealing performed during a larger cleaning job and a higher minimum for a standalone return, if your costs support that structure. The add-on minimum can be lower because some travel and setup are already covered by the main job.

State the minimum plainly. Write, “Concrete sealing minimum: $400,” rather than quietly raising the square-foot rate until the number works. Customers understand a mobilization minimum better than a tiny patio quoted at a rate far above your advertised range.

Do not waive the minimum just to keep a bundled estimate looking cheap. Instead, offer to include nearby walkways, a porch, or another suitable concrete area up to the value of the minimum, provided the added scope fits your process.

How do you sell concrete sealing without sounding pushy?

Sell sealing by showing the cleaned surface, explaining the scope, and offering a clear optional price. Do not promise permanent stain prevention, a specific lifespan, or performance your chosen product does not support.

Bring it up while quoting the cleaning, not after the invoice is paid. Tell the customer that cleaning and sealing are separate steps, then ask whether they want both options shown. Permission keeps the conversation simple.

Use three choices when the property supports them:

1. Cleaning only.
2. Cleaning plus sealing for the main driveway.
3. Cleaning plus sealing for all suitable concrete.

This structure lets the customer control the budget without forcing you to discount. It also makes the add-on concrete, because each option has a measured scope and total price.

Use close, evenly lit surface photos to document condition before quoting. The guide on before and after photos that sell jobs covers a repeatable photo process. Never alter photos or imply a finish that your process cannot deliver.

If the customer says the add-on costs too much, reduce scope before reducing rate. Our guide to handling a “That’s Too Expensive” price objection gives you a direct way to hold the line.

What should every concrete sealing quote include?

Every quote should define the measured area, cleaning scope, preparation, product or finish category, application scope, exclusions, customer responsibilities, and total price. Clear terms prevent the customer from filling gaps with assumptions.

List each surface by name and square footage. Note visible cracks, spalling, old coatings, stains, moisture concerns, patched sections, and other conditions that may affect appearance or application.

State what preparation is included. Standard cleaning should not quietly become coating removal, extensive degreasing, crack repair, or restoration after the quote is accepted. Put uncertain work behind an inspection or a separately approved change.

Define access and scheduling responsibilities. The customer may need to move vehicles, furniture, planters, grills, and other belongings before arrival. Also explain that work depends on suitable site and weather conditions under the product instructions.

Include payment timing, change approval, and your process if hidden conditions appear. Do not copy legal language from another contractor. Have your own terms reviewed for your business and location.

If you are still tightening the company side of the operation, review insurance for a pressure washing business. Insureon reports average annual workers compensation insurance of $1,601 for pressure washing companies, although your need and price depend on your operation.

When your pricing and scope are ready, put the service where customers can understand it and request a quote. You can get a WasherAuthority website built around the services you actually sell.
