Create Your Free AccountSpec your base depth before any dollar amount reaches the client. Residential driveways need 6–8 inches of compacted aggregate; parking lots taking regular truck traffic need 8–12. A contractor who skips or skimps this step is selling a 3-year driveway, not a 20-year one. The client won't know until the cracks start. State the spec in writing and photograph the compacted base as part of your close-out documentation.
Name the mix design, not just 'asphalt.' Type II surface course for driveways. Type I binder under a Type II finish for lots handling delivery vehicles. Polymer-modified for coastal jobs or anything with more than 80 degrees of seasonal temperature swing. Clients don't know what this means — but putting it in the proposal means you can't be pressured to substitute a cheaper mix at the plant. It also gives you a paper trail if something fails.
Don't sealcoat new asphalt for at least 90 days. Six months is better. The petroleum oils in fresh hot mix need time to oxidize and cure; sealing too early traps volatiles and prevents proper hardening. Clients will push for it immediately. Explain it once in writing, schedule the sealcoat application explicitly at signing, and then do it right. Contractors who seal on day one charge less and generate more callbacks.
If the job is a parking lot with any ADA spaces, own the layout entirely. The federal ratio is one accessible space per 25 for lots under 100 total. Van-accessible stalls require 8-foot access aisles — not 5-foot. Getting it wrong costs $25,000–$75,000 in retrofits and federal penalties. Pull the lot dimensions, spec the count and placement yourself, and put it in the proposal. Clients who discover non-compliance after striping will remember who drew the lines.
Break pricing into four separate line items: base prep, hot mix, sealcoat, and striping. Every time, every job. A client comparing your all-in number against a competitor quoting only the hot mix layer will assume you're overpriced. Show the breakdown. Base prep alone runs $0.35–$0.80 per square foot; clients who see that number understand why your total doesn't match someone who left it out entirely.
