Getting a Sealcoating Estimate: What to Expect and What to Ask

## Why the Estimate Matters More Than the Price Most homeowners start the sealcoating process by asking "how much does it cost?" That is the wrong first question. The right first question is "what am I getting for that price?" A sealcoating estimate is not just a number. It is a document that tells you exactly what work will be done, what products will be used, what prep is included, and what is not. Two estimates at the same price can describe very different scopes of work. Two estimates at different prices might describe the same work — one contractor just charges more. Understanding what a professional sealcoating estimate should include puts you in a position to compare quotes accurately and avoid the most common mistakes homeowners make when hiring a sealcoating contractor. For background on pricing ranges, see our [sealcoating cost guide](/blog/sealcoating-cost-guide-oregon). ## What a Professional Estimate Should Cover A thorough sealcoating estimate includes these components: ### 1. Pavement Assessment Before quoting a price, a reputable contractor walks your driveway and assesses its current condition. They are looking at: - **Surface condition** — How much UV oxidation has occurred? Is the surface still smooth or has it become rough and porous? - **Cracking** — What type, how wide, how extensive? Hairline cracks versus structural cracks require very different treatment. - **Drainage** — Does water flow off the driveway or pool in low spots? Standing water areas may need additional attention. - **Oil stains and chemical damage** — Petroleum products dissolve asphalt binder. Stained areas need priming before sealcoat will adhere. - **Previous coatings** — Is there existing sealcoat that is peeling or flaking? Loose material needs removal before recoating. - **Edge condition** — Are driveway edges intact or crumbling? Edges are the most vulnerable area and often need extra attention. A contractor who quotes over the phone without seeing your driveway is guessing. Phone estimates are fine as a rough ballpark, but the actual quote should be based on an in-person (or at minimum photo-based) assessment. ### 2. Scope of Work The estimate should clearly state what is included: | Item | What to Look For | |------|-----------------| | **Surface cleaning** | Power washing, blowing, or sweeping? Power washing provides the best surface for sealcoat adhesion. | | **Crack filling** | Included? Up to what width? What product (cold pour vs. hot rubberized)? How many linear feet? | | **Oil spot treatment** | Included? How many spots? What primer product? | | **Number of coats** | One or two? Two coats is the industry standard for proper protection. | | **Product type** | Asphalt emulsion or coal tar? Commercial-grade or consumer-grade? Brand name? | | **Sand additive** | Included? Sand improves traction and durability. Standard in professional applications. | | **Edge work** | How are edges handled? What about the garage door threshold? | | **Cure time and barricading** | How long will your driveway be blocked off? Who provides barricades? | | **Cleanup** | Is cleanup included? Overspray protection for adjacent surfaces? | ### 3. Written Quote The estimate should be in writing — either a printed document or a digital quote sent to your email. It should include: - Contractor name, license number, and contact information - Your property address - Itemized scope of work - Total price (and per-square-foot rate if applicable) - Payment terms - Warranty or guarantee (if offered) - Estimated schedule or completion date - Any exclusions or conditions A verbal quote is not an estimate. It is a conversation. Get it in writing. ## Red Flags to Watch For ### Door-to-Door Solicitation Contractors who show up unannounced offering to sealcoat your driveway "since they are in the neighborhood" are a significant risk. This business model relies on impulse decisions and often involves diluted products, single-coat applications, and crews that will not be reachable if there is a problem. Legitimate sealcoating contractors have scheduled work and do not need to canvass neighborhoods for jobs. If someone knocks on your door, get their company name and look them up before committing to anything. ### No Physical Address or License Oregon requires contractors performing work over $1,000 to hold a Construction Contractors Board (CCB) license. Many sealcoating jobs fall below this threshold, but a licensed contractor signals professionalism and accountability. At minimum, the contractor should have a verifiable business address, phone number, and online presence. ### Pressure to Decide Immediately "This price is only good today" is a sales tactic, not a legitimate business practice. A professional estimate should be valid for at least 30 days. If a contractor pressures you to sign on the spot, that is a red flag. ### Dramatically Low Pricing If one quote is 40-50% below the others, something is different. Common explanations: single coat instead of two, diluted product, no crack filling included, no cleaning included, or an inexperienced crew. The cheapest sealcoating job is not the best value if it fails in one year. In the Oregon market, professional sealcoating for a two-car driveway should fall between $175 and $300. A quote below $100 for a standard driveway should prompt questions about scope and product quality. ### No Written Estimate If a contractor will not put their quote in writing, do not hire them. A written estimate protects both parties and ensures there is no confusion about what was agreed upon. ## Questions to Ask Every Contractor Use this list when evaluating sealcoating contractors: ### About the Product - What brand and type of sealant do you use? - Is it commercial-grade or consumer-grade? - Do you add sand for traction? - What is the solids content of the product? ### About the Process - How many coats will you apply? - How do you clean the surface before application? - Is crack filling included? Up to what size? - How long between coats? - How long before I can drive on it? ### About the Business - Are you CCB licensed? (Ask for the number and verify at Oregon CCB's website) - Do you carry liability insurance? - How long have you been in business? - Can you provide references from recent jobs in my area? - Do you offer any warranty on the work? ### About the Schedule - When can you schedule the work? - What happens if it rains on the scheduled day? - How much notice will I get before you arrive? A contractor who answers these questions confidently and completely is one you can trust. A contractor who is evasive, dismissive, or cannot answer basic product questions is one to pass on. ## What Affects Your Estimate Price Understanding the cost drivers helps you evaluate whether a quote is reasonable for your specific situation: ### Driveway Size The biggest factor. Larger driveways cost more total but less per square foot. Most contractors have a minimum charge of $125-$200 that applies regardless of size. ### Surface Condition A driveway in good condition needs less prep. A driveway with extensive cracking, oil stains, or previous coating failures needs more work before any sealcoat goes down. Prep work can add 20-40% to the base sealcoating cost. ### Access Steep driveways, narrow access, and driveways surrounded by landscaping that needs protection all add time. Time equals cost. ### Product Quality Commercial-grade sealants with higher solids content cost more per gallon but provide better coverage and longer-lasting protection. The product difference between a $175 job and a $250 job is often worth the premium. ### Season and Demand Oregon's sealcoating season runs roughly late June through mid-September. Peak demand in July and August means full schedules and less flexibility. Early and late season may offer slightly better pricing. ## How Cojo's Estimate Process Works When you contact Cojo for a sealcoating estimate, here is what happens: **Step 1: Initial conversation.** We ask about your property — driveway size, approximate age, any known issues. This gives us enough context to confirm that sealcoating is the right service and to schedule an assessment. **Step 2: On-site assessment.** We visit your property, measure the driveway, evaluate surface condition, identify any cracks or damage that need attention, and note access considerations. For properties in the Willamette Valley, this is usually scheduled within a few days of your initial call. **Step 3: Written estimate.** Within 24-48 hours of the assessment, you receive a detailed written estimate covering: measured square footage, recommended prep work, product specification, number of coats, total price, and estimated schedule. No hidden fees, no vague line items. **Step 4: Scheduling.** If you approve the estimate, we schedule the work within Oregon's sealcoating season. We confirm the date in advance and monitor weather forecasts. If rain threatens, we reschedule proactively rather than risk applying sealcoat in unfavorable conditions. **Step 5: Execution and follow-up.** The work is completed per the estimate. We barricade the driveway for curing and follow up to confirm you are satisfied with the results. ## Getting Started The best time to get a sealcoating estimate in Oregon is April through June — before the summer season fills up. This gives you time to compare quotes, ask questions, and secure your preferred scheduling window. If you are not sure whether your driveway needs sealcoating, that is fine. An assessment will tell you. If we look at your driveway and determine that sealcoating is not the right investment — because the pavement needs repair instead, or because the existing sealcoat still has life — we will tell you that directly.
