A Proper Patio Quote vs a Piece of Paper: How to Tell the Difference
A real patio quote covers nine things - scope, materials with specs, engineering, council pathway, warranty terms, payment schedule, exclusions, the contact person, and a clear total. A "piece of paper" quote is a number on a single page. Three quotes for the same patio can vary by $20,000 - and the difference is almost never about who's making more profit. It's about what's actually included.
Why this guide exists
Every week we have the same conversation. Someone's got three quotes in front of them. The numbers are wildly different. They want to know which one is "real" and which one is too good to be true.
The honest answer is that all three quotes are usually for genuinely different jobs - even when they look like they're for the same patio. The cheap one's missing engineering. The middle one's used a lighter spec. The expensive one's quoted full coastal spec when you don't need it. Without the detail, the customer's left guessing.
This guide walks you through what should be in a real quote, the red flags that tell you a quote is a marketing document rather than a building document, and how to compare three quotes that look completely different on the surface.
The nine things every patio quote should have
If your quote is missing any of these, ring the builder before signing and ask for the detail. A real builder will happily fill in the gaps. A dodgy one will get evasive.
1. Scope of works - in plain language
What are they actually building? Size in square metres, location on the property, what's being demolished or removed first, what's being kept. "Build a 32sqm insulated patio at the rear of the property, attached to the existing house ledger, replacing the existing pergola structure" is a scope. "Patio supply and install" is not.
2. Materials with brand and spec
Not "Colorbond". Which Colorbond - standard or Ultra? What colour? What thickness on the panel? What grade are the fixings - 304 stainless, 316 stainless, or galvanised? What's the gutter spec? What's the post and beam steel grade and finish? Every material should be named, specified, and verifiable.
This matters because the gap between "Colorbond" and "Colorbond Ultra" on a coastal site is the difference between a roof that looks good in 2046 and one that's chalking by 2034. Same brand. Different product. Different price.
3. Engineering details
Any patio over a certain span or height needs structural engineering certification. The quote should either include the engineering as a line item, or state that engineering is included in the price. If it's silent on engineering, ask. The engineering certificate is what gets you signed off by council and what your insurance will ask for if a tree ever drops on the patio.
4. The council pathway
Some patios are exempt development. Some need a complying development certificate (CDC). Some need a full development application (DA). The quote should state which pathway your job is on and who's responsible for lodging it.
If a builder says "you don't need council approval" without checking, get a second opinion. Erina, Wamberal, Newcastle East and inner-suburb Lake Macquarie all have specific local rules that change the pathway, and councils will ask questions later if the work was done outside the rules.
5. Warranty terms in writing
What's the workmanship warranty - 12 months, 2 years, longer? What's the structural warranty - 6 years, 10 years? What's the materials warranty (which usually comes from the manufacturer, not the builder)?
NSW statutory warranties on residential building work are 6 years for major defects and 2 years for everything else. That's the floor. A real builder will offer those terms in writing. Some offer longer.
6. Payment schedule
The deposit and the progress payment dates. NSW Home Building Act limits this - we'll cover the rule below. The schedule should tie to physical milestones (posts up, roof on, completion) not arbitrary dates.
7. Exclusions
What's NOT included. Tree removal, electrical work, decking under the patio, paving, painting of existing fascia, removal of old structures - anything that's not in scope should be listed as an exclusion. If the quote has no exclusions section at all, that's a red flag - because there are always exclusions.
8. The contact person
The name and direct phone number of the person who put the quote together. Not a generic office number. Not "your account manager will be assigned". The person you can ring on Sunday afternoon when you've got a question.
9. A clear total - not a "from" price
One number, GST included, signed and dated. Not "from $X". Not "starting at $X". The actual amount you'll pay if you sign as-is.
The red flags
A few specific things should raise an eyebrow.
A single-page quote with no detail. A real patio quote is rarely under three pages. There's just too much to cover. If your quote fits on one page, the rest is either missing or assumed.
"From $X" pricing in the quote itself. Marketing materials can say "from $X" - that's just advertising. A formal quote shouldn't. If the quote says "from $14,990" and there's still a range in it, you don't have a quote, you have a teaser.
No materials brand or spec. "Colorbond roof, steel posts, stainless fixings" tells you almost nothing. Anyone can write that. The brand, grade, gauge and colour need to be specific.
No warranty terms. If the warranty section is blank, missing, or just says "12 months", you're not getting the statutory NSW protections in writing. They still apply by law - but a builder happy to leave them off the page is a builder happy to argue them later.
No exclusions section. Every job has things that aren't included. A quote with no exclusions section means either (a) the builder forgot, or (b) the builder is planning to charge you for the exclusions as variations once the job starts.
A deposit over 10% on a contract over $20,000. This is a legal red flag, not just a stylistic one. NSW law caps it. Any builder asking for more is either ignorant of the law or hoping you are.
No named contact person. Generic office numbers and unsigned quotes mean you'll be on hold when something goes wrong. Find the person, get their direct number.
The story of three quotes between $14k and $35k
A couple in Charlestown rang us a few months back. Quote in hand from us, plus two others. Same brief: roughly 28sqm insulated patio off the back of a single-storey house. Three quotes:
- Quote A: $14,200
- Quote B: $24,800 (ours)
- Quote C: $35,400
The first reaction was the obvious one - is the cheap one too good to be true, or is the expensive one ripping us off? Reasonable question. We sat down with them at the kitchen table and walked through all three line by line.
Quote A ($14,200) turned out to be a single-skin patio (not insulated), standard Colorbond (not Ultra, even though Charlestown gets enough coastal weathering to justify it), 304 stainless fixings, no engineering line item, "council to be arranged separately", and a single-page quote with no exclusions and a 25% deposit. Once you priced in the engineering, council pathway, the upgrade to insulated panels (which is what the customer actually wanted), and corrected the deposit to comply with the Home Building Act, the real number was around $19,500 - and that's still on standard fixings.
Quote B (ours, $24,800) was the proper job. Insulated panels, Colorbond Ultra coastal grade because Charlestown sits close enough to the lake-and-coast wind path to warrant it, 316 stainless throughout, full engineering, council pathway lodged by us as part of the job, four-page quote with everything specified, a compliant 10% deposit, and progress payments tied to milestones.
Quote C ($35,400) was a coastal-spec build with a few additions the customer didn't actually need - LED downlights wired in, a feature beam in hardwood that didn't fit the house style, and an over-spec'd footing detail that added a couple of thousand for a job that didn't need it. The builder wasn't being dishonest - he was just quoting a higher-spec job than the brief required. That's a legitimate quote, just not the right job for the customer.
Once we'd walked through all three, the choice was straightforward. Quote A wasn't actually cheaper - it was less. Quote C wasn't actually better - it was more. Quote B was the right fit. The customer signed on the spot.
“The thing that sold me was the Patio Empire project manager literally pulling out the other two quotes and telling me which lines were missing. No bagging the other companies, just walking through what each one did and didn't include.

How to compare three quotes apples to apples
Forget the headline number for a minute. Make a one-page table with these columns and fill in what each quote actually says:
| What to compare | Cheap quote signal | Proper quote signal |
|---|---|---|
| Scope detail | 'Patio supply and install' | Specific size, location, demolition, what stays |
| Roof material | 'Colorbond' | Brand, product line (e.g. Ultra), colour, thickness |
| Insulation spec | Not mentioned, or 'insulated panel' | Panel thickness, R-value, manufacturer |
| Fixings | 'Stainless steel' | 316 stainless (coastal) or 304 with reasoning |
| Engineering | Silent or 'extra' | Included as line item or in total |
| Council pathway | 'You sort it' | Pathway named, who lodges it, included or extra |
| Warranty | Not in writing or '12 months' | Workmanship and structural terms in writing |
| Deposit | 20%+ on a $25k+ job | 10% on contracts over $20k (NSW HBA) |
| Progress payments | Date-based | Milestone-based with named milestones |
| Exclusions | Section missing | Specific list of what's not included |
| Contact person | Office number only | Named person, direct number |
Once the columns are filled in, the cheap quote almost always has gaps where the proper quote has detail. The price difference usually evaporates by the time you've costed in the gaps - and what's left is genuine differences in spec or scope, not profit margin.
Why we walk you through the quote verbally before sending it
Most builders email a PDF and follow up two days later asking if you've got any questions.
We don't do that. Once we have the quote ready, we ring you and book a 20-30 minute call - usually a phone call, sometimes a video call - and walk through it before you ever see the document. Section by section. Why this material, why this size, why this engineering allowance, what's excluded and why.
Then we email it. By the time you read it, you already understand it. There are no surprises in the inbox.
This isn't a sales tactic. It's how you avoid the situation where someone signs a quote they didn't fully understand, then has questions on day three of the build that should have been asked on day zero. Saves us time. Saves you stress. Done properly, every time.
Deposits, progress payments, and the NSW Home Building Act
Quick legal grounding so you can spot the issues yourself.
For residential building work over $20,000 in NSW, the Home Building Act 1989 sets specific limits:
- Maximum deposit: 10% of the contract price. Not 15%, not 20%, not 25%. Anyone quoting a deposit higher than that is either ignorant of the law or banking on you not knowing.
- Progress payments must be tied to milestones, not arbitrary dates. Typical milestone structure is deposit on signing, progress payment when frame and posts are up, progress payment when the roof is on, balance on completion.
- A signed contract is required for any residential building work over $5,000. Verbal agreements aren't enough. The contract should reference the same scope and price as the quote.
- Home Building Compensation cover applies to contracts over $20,000 for most residential work. Your builder should provide a certificate.
If the quote you've got doesn't comply with these basics, don't sign it. Ask the builder to fix it - and watch how they respond. The good ones will apologise and reissue. The dodgy ones will tell you it's "industry standard". It's not.
The "I'll match anyone's quote" trap
A few builders run a "we'll match any genuine quote" line. On the face of it, it sounds reasonable. In practice, it almost always means one of two things.
First, they were quoting too high to start with - so they'd rather drop their number than lose the job. That tells you their original quote had a fat margin built in. Why was that there in the first place?
Second, they're matching the headline price by quietly downgrading the spec to match. You think you're getting their quote at the cheap quote's price - what you're actually getting is the cheap quote's spec at a slightly different signage. Same problem, different label.
We don't match quotes. The price we put on the page is the price for the job we've designed. If you've got a cheaper quote and you'd rather go with it, that's your call - and we'll wish you well. If you'd like us to look at the cheaper quote and explain what's actually different so you can make an informed decision, we'll do that for free, no strings.
That's a different conversation, and it's the one that's actually useful.
The short version
Three quotes for the "same" patio can vary by $20,000. The price spread is almost never about profit margin - it's about scope, spec, and what's actually included. A real quote covers nine specific things. A piece of paper covers a number.
Print the nine items out. Hold every quote up against them. Ring the builders back with specific questions about anything missing. The builders who answer happily are the ones to keep talking to. The builders who get evasive have just told you something important.
A patio is the kind of build you do once. Spend the extra hour up front getting the quotes properly compared, and you'll save yourself a long stretch of grief later on.
