How Concrete Sealing Is Priced: What Goes Into a Quote

One of the most common questions homeowners have before booking a concrete sealing job is simply what it is going to cost. It is a fair question, and also one that does not have a single flat answer, because sealing pricing depends on the specific property being sealed. This guide walks through the actual factors that go into a quote so that when you request one through /contact or by, you understand what is being assessed and why the number reflects your property specifically rather than a generic rate.

Why there is no flat price list

It would be simpler to publish a flat per-square-foot rate and let homeowners calculate their own quote. In practice, that approach misrepresents how much variation exists between properties. Two driveways of roughly the same size can require very different amounts of work depending on their condition, prior sealer history, and finish choice. A generic price list either overcharges the straightforward jobs to cover the complicated ones, or underquotes the complicated jobs and leaves the homeowner with unexpected costs partway through. TriCity Concrete Sealing avoids both problems by pricing every job individually after a free site assessment, so the quote you receive reflects your actual concrete rather than an average across properties that may not resemble yours at all.

Surface area is the starting point

The size of the surface being sealed is naturally the first factor in any quote, whether that is a driveway, patio, walkway or a combination of surfaces on the same property. Larger surfaces require more sealer product and more labour time, and this scales roughly with square footage as a baseline. That said, size alone does not determine the final price, which is why two properties with similar surface areas can still receive noticeably different quotes once the other factors below are taken into account.

Condition and prep work

The condition of the concrete going into the job has a real effect on scope. The sealing process starts with pressure washing and cleaning the surface, letting it dry fully, and repairing minor issues before masking and applying sealer. A driveway with heavy staining, embedded dirt, or minor surface damage from years of freeze-thaw exposure requires more cleaning and prep time than a driveway that has been well maintained or was sealed relatively recently. Minor crack or spall repair, where needed, also adds to the scope. This is one of the main reasons an in-person assessment matters more than a phone estimate: condition is difficult to judge accurately without actually looking at the surface.

Prior sealer history

Whether a surface has been sealed before, and with what type of product, factors into the quote as well. TriCity applies high-quality solvent-based acrylic sealer, which re-emulsifies seamlessly with a previous solvent-based coat, generally making a straightforward recoat over an existing compatible sealer more efficient than sealing bare, never-sealed concrete or addressing an incompatible prior coating. More detail on why this matters is covered in our guide on solvent-based versus water-based sealers. If you are not sure what was used on your property before, or whether it has ever been sealed at all, that is exactly the kind of thing to raise during the assessment rather than guess at ahead of time.

Finish and add-ons

Finish choice, matte, semi-gloss or gloss, is discussed as part of the quoting conversation, since it is a decision about appearance and, in some cases, surface feel underfoot, covered in more depth in our guide comparing the three finishes. A non-slip additive can be added to any finish for surfaces like pool patios or steps where extra traction matters, and this is raised as an option during the assessment rather than presented as a hidden extra afterward. Being upfront about these choices during the quote means the price you receive already reflects the finish and any additives you have decided on, rather than changing later.

Surface type and service category

Different surface types carry somewhat different considerations that factor into scope and, by extension, price. Driveway sealing, covered at /services/driveway-sealing, deals with the most traffic and salt exposure of any residential surface. Stamped concrete sealing, at /services/stamped-concrete-sealing, often involves more careful attention to pattern lines and colour enhancement, particularly with gloss finishes. Exposed aggregate sealing, at /services/exposed-aggregate-sealing, has its own texture considerations that affect how sealer is applied and how much product is needed. Patios, walkways and commercial surfaces each come with their own typical scope as well. None of these categories carries a fixed rate on its own, but understanding which category your project falls into helps frame what the assessment will focus on.

What is included in the price

A TriCity Concrete Sealing quote reflects the full process: pressure washing and surface cleaning, drying time, minor repair work where needed, masking to protect adjacent surfaces, and sealer application by sprayer with back-rolling to avoid lap marks. It also reflects the finish you have chosen and any additive requested. Beyond the physical work, every job is backed by a 5-year workmanship warranty, which is part of what you are getting for the price, not a separate add-on. With more than 500 projects completed across London, Woodstock, Brantford, St. Thomas, Stratford, Ingersoll, Tillsonburg, St. Marys, Aylmer and Simcoe over more than 8 years in business, the pricing process is built around getting the scope right the first time rather than adjusting mid-project. More on what the warranty actually covers is available at /warranty.

Why free assessments matter for accurate pricing

A phone-only estimate, without seeing the property, can only ever be a rough guess, since so much of what determines actual scope, condition, prior coatings, surface texture, access for equipment, is difficult to judge without being on site. TriCity's free site assessment exists specifically to remove that guesswork. A member of the crew looks at the actual surface, discusses finish and any additive preferences, and provides a quote based on what the job genuinely requires. There is no obligation attached to requesting the assessment, and it remains the most reliable way to get pricing that will not shift once work begins.

Access, layout and equipment considerations

Beyond the surface itself, practical site factors can shape scope in ways that are easy to overlook until an assessment brings them up. A driveway with a steep slope, an unusual layout with multiple curves and edges, or tight clearance next to garage doors, fencing or landscaping can add time to masking and back-rolling, since the goal is always a clean, even coat with no lap marks regardless of how straightforward or awkward the geometry is. Properties with attached walkways, porch steps or a patio that connects directly to the driveway are sometimes quoted as a combined project, which can be more efficient than pricing each surface in isolation, depending on layout. None of this is meant to complicate the process for the homeowner; it simply means the crew doing the assessment is looking at the whole property, not just measuring square footage from a satellite image.

Comparing quotes from different contractors

It is common, and reasonable, for homeowners to get more than one quote before deciding who seals their concrete. When comparing quotes, it is worth looking past the bottom-line number to what is actually included. A lower quote that uses water-based sealer, skips proper cleaning and drying time, or does not include any workmanship warranty is not necessarily comparable to a higher quote that includes solvent-based product, full prep work and a 5-year warranty backing the result. Asking each contractor what sealer type they use, what prep work is included, and whether the price includes any warranty coverage is a fair way to make sure you are comparing like-for-like scopes rather than just two numbers on paper.

Getting a quote for your property

If you are planning to seal a driveway, patio, walkway, stamped concrete surface, exposed aggregate area, or a commercial property anywhere in London, Woodstock, Brantford, St. Thomas, Stratford, Ingersoll, Tillsonburg, St. Marys, Aylmer or Simcoe, the most straightforward next step is to book a free site assessment. There is no cost or commitment involved in getting a number, and it gives you a real basis for comparison if you are also getting quotes from other contractors. Request yours through /contact
