What to Look for in an Asphalt Quote (And the 5 Red Flags to Walk Away From)
AI Overview
A good asphalt quote spells out sub-base depth, asphalt thickness, compaction spec, edge restraint, drainage falls, and warranty, in writing. Bad quotes are vague one-liners with just a square-metre rate. The 5 biggest red flags: no site visit, vague pricing, no spec sheet, large upfront deposit, and pressure to decide today. This guide explains what to look for and how to compare contractors apples-to-apples.
Key Highlights
- →Every legitimate quote starts with an on-site visit, never a phone-only price
- →Look for specifics: sub-base depth, asphalt thickness, compaction spec
- →Written spec sheet beats a verbal estimate every time
- →Deposit should be 10-20%, not 50%. Half-upfront is a red flag
- →Walk away from any contractor pressuring you to decide on the day
- →Cheapest quote often means cheapest sub-base. Compare like-for-like specs
We've quoted thousands of driveways across Launceston and Northern Tasmania. The number of times we've come second to a cheaper quote that we then watched fail 3 years later — it's a pattern.
This guide walks through what a proper asphalt quote contains, what's missing from the bad ones, and the specific red flags that should make you walk away even if the price looks great.
What a good asphalt quote includes
- Itemised pricing: site prep, base, asphalt, kerb work, line marking (if applicable) all broken out
- Sub-base material and depth (e.g. '150mm compacted FCR road-base')
- Asphalt mix specification and thickness (e.g. '40mm dense graded AC10 wearing course')
- Compaction spec (e.g. '95% MMDD' or 'rolled with 2-tonne vibrating roller in 75mm lifts')
- Edge restraint detail (e.g. 'concrete kerb on both edges' or 'hardwood timber edge')
- Drainage falls (e.g. '1:50 fall toward road stormwater pit')
- Warranty period and what's covered
- Deposit terms, payment schedule, expected start date
If the quote you're holding is a one-page document with a single dollar figure and no breakdown, ask for the detail. A contractor who can't or won't give it is telling you something important.
Red flag 1: No site visit
A legitimate asphalt quote is impossible without seeing the site. Slope, access, existing surface, sub-grade soil type, edge conditions — all of these change the price significantly. Any contractor giving you a 'quote' over the phone without coming out is either guessing or going to ambush you on price later.
Red flag 2: Vague pricing
Watch for this exact phrase
If the quote says 'standard residential driveway, $X total' with no breakdown, that's a guess dressed up as a price. Site-specific factors (access, base prep, drainage, edge work) move the real cost by thousands of dollars on the same square metres. Vague pricing = wrong pricing.
Red flag 3: No written spec sheet
Verbal promises are worth nothing when the asphalt fails in three years. Every legitimate quote includes a written spec sheet — sub-base depth, asphalt thickness, compaction standard, finish type. If you're handed a verbal estimate and a deposit slip, ask for the spec in writing before signing anything.
Red flag 4: Large upfront deposit
Industry standard is 10-20% deposit. Some contractors ask for 50% upfront, then disappear or do a token amount of work to justify keeping it. A 10-20% deposit is enough to commit a contractor and cover their materials risk; a 50% deposit shifts all the risk to you. Walk away.
Red flag 5: Pressure to decide today
The 'special price if you sign today' tactic is straight out of the dodgy-contractor playbook. Legitimate quotes have a validity period (usually 30 days), they don't expire at the end of the site visit. If you're being pressured, the contractor knows their offer doesn't look so good when you've had a chance to compare it.
How to compare three quotes apples-to-apples
- Get all three quotes on the same scope (same area, same edge work, same drainage requirements)
- Line up the spec sheets side-by-side — focus on sub-base depth and compaction first
- Adjust the prices mentally for any spec differences (e.g. one contractor specs 100mm sub-base, another 150mm — the 150mm is a fairer comparison to a quality job)
- Check the warranty terms. A 10-year structural warranty from a small business that's been around 2 years is worth less than a 5-year warranty from a 20-year business
- Ask each contractor 'what's likely to fail first on this driveway?' — honest ones will give you a real answer
FAQ
Common questions
Is the cheapest quote ever the right choice?+
Sometimes, if the specs match. If one quote is significantly cheaper than two others on the same scope, it's almost always because they're specifying less sub-base, thinner asphalt, or cheaper base material. Cheaper now means more expensive over the driveway's lifetime.
How many quotes should I get?+
Three is the sweet spot. One quote gives you no comparison. Five quotes wastes everyone's time and you'll struggle to compare them all. Three lets you triangulate the fair market price and identify outliers.
What if I've already paid a deposit and the contractor is now showing red flags?+
If the contract is in writing, you have rights under the Australian Consumer Law to cancel within the cooling-off period (usually 5 business days in Tasmania). If you're outside that window, document everything in writing and contact Consumer Affairs Tasmania.
How do I check a contractor is legitimate?+
Verify their ABN at abr.business.gov.au. Ask for a copy of their public liability insurance certificate (even though we don't advertise insurance details, ours is current and we'll show it on request). Ask for two recent local job references and actually call them.
