Kitchen extraction cleaning - surveys
A reliable extraction cleaning quote starts with a proper site survey - the cleaner coming to see and assess your actual system before pricing the job. A quote given without one, over the phone or by guesswork, is unreliable. Here is what a good pre-quote site survey looks like, and why it matters for getting an accurate quote and a proper clean. This is general guidance.
The short answer
When you ask for an extraction cleaning quote, how the contractor arrives at the price tells you a lot. A good contractor surveys your system first; a dubious one quotes blind. Here's what a good pre-quote site survey looks like, and why it matters. This is general guidance. Why a survey comes first. The right scope and price for cleaning your extraction depend on the specifics of your system - how much ductwork there is, how greasy it is, how it's accessed, and any complications. A cleaner can't know these without seeing your system. So a good quote starts with a survey: the cleaner comes to assess your actual system before pricing the job, so the quote reflects what actually needs doing. Quoting without seeing the system is guessing. What a good survey covers. A proper pre-quote survey involves the cleaner assessing: The layout and extent. The ductwork run from canopy to fan - its length, route and configuration - so they know how much system there is to clean. A big, complex run is a bigger job than a short, simple one. The grease condition. How heavy the grease build-up is (and where) - which affects the work involved (a heavily-fouled system takes more work than a lightly-loaded one). The access. How the system can be reached for cleaning - the existing access panels along the ductwork, the fan's location and access (roof or in-line), and whether more access is needed (fitting panels). Access hugely affects the job. Any complications. Things that affect the work: a roof fan needing height access, an awkward or convoluted duct route, a UV system, fire dampers, a difficult location. So the survey builds a real picture of your specific system - the basis for an accurate quote. What it produces. From the survey, the cleaner can scope the job accurately (what needs doing for your system) and give you a realistic, specific quote - covering the actual work, not a generic figure. So the quote is grounded in your system, and less likely to change or fall short. A good survey also often produces useful information for you (the state of your system, what it needs). The warning sign of no survey. A quote given without a survey - over the phone, from a photo, or by generic guesswork - is unreliable, and a warning sign. Without seeing your system, the cleaner doesn't really know it, so the quote may be: too low (a tempting price that rises later when the reality is seen, or reflects an under-scoped, superficial clean that skips the hidden parts); or too high (padded to cover the unknowns). Either way, it's not a properly-scoped quote. And a contractor who doesn't survey before quoting may be one who doesn't do a thorough job (the survey being the first stage of a proper clean - as covered in the survey-access-clean-certify page). So no survey is a red flag. What it signals. So a good site survey before a quote signals a serious, competent contractor who will scope and price the job properly - and want to understand your system before committing to a price and a clean. Its presence is reassuring; its absence is a warning. The takeaway. So a good extraction cleaning quote starts with a proper site survey - the cleaner assessing your actual system (layout, grease, access, complications) before pricing - which gives you an accurate, specific quote and a clean scoped to your real system. A quote without a survey is a guess. So expect and insist on a proper survey before a quote. This is general guidance.
Key points
Why the survey comes first
A good extraction cleaning quote starts with a survey because the right scope and price depend on the specifics of your system - and the cleaner can only know those by seeing it. How much ductwork there is, how greasy it is, how it's accessed, and any complications all determine what the job involves and what it should cost. None of that can be known reliably without looking at your actual system. So a good contractor surveys first: they come to assess your system before pricing the job, so the quote reflects what actually needs doing.
Quoting without seeing the system is, in effect, guessing - the cleaner is pricing a system they haven't seen, based on assumptions. So the survey isn't a formality; it's what makes the quote real. A contractor who insists on surveying before quoting is showing they take the job (and the accuracy of the quote) seriously. So why the survey comes first - the price depends on your actual system - is the foundation: the specifics of your system drive the scope and price, so they must be assessed before a meaningful quote. The following sections cover what a good survey covers, what it produces, and why no survey is a warning sign. So a proper quote needs the system seen first. This is general guidance.
What it covers
A proper pre-quote survey involves the cleaner assessing several things about your system. The layout and extent: the ductwork run from canopy to fan - its length, route and configuration - so they know how much system there is to clean (a big, complex run is a bigger job than a short, simple one). The grease condition: how heavy the grease build-up is, and where - which affects the work involved (a heavily-fouled system takes more work than a lightly-loaded one). The access: how the system can be reached for cleaning - the existing access panels along the ductwork, the fan's location and access (roof or in-line), and whether more access is needed (fitting panels) - since access hugely affects the job.
And any complications: things that affect the work - a roof fan needing height access, an awkward or convoluted duct route, a UV system, fire dampers, a difficult location. So the survey builds a real, specific picture of your system: how much there is, how greasy, how accessible, and what's tricky. This is exactly the information needed to scope and price the job accurately. A good surveyor looks at all of it (not just glances at the canopy), because all of it affects the clean. So what it covers - layout, grease, access, complications - is the substance of a good survey: a proper assessment of the specific system to be cleaned. So the survey assesses your system's extent, grease, access and complications. This is general guidance.
What it produces
From the survey, the cleaner can produce what you actually want: an accurate, specific quote. Having assessed your system (its extent, grease condition, access and complications), they can scope the job properly - what needs doing for your particular system - and price it realistically, covering the actual work rather than a generic figure. So the quote is grounded in your real system, and far less likely to change later or fall short of what's needed.
This benefits you in two ways. The price is reliable: because it's based on the real job, it's less likely to rise once work starts (no nasty surprises), and it reflects the actual scope. And the clean is properly scoped: the quote covers the whole job your system needs (the full ductwork run, the fan, the access), so you're buying a complete clean, not an under-scoped one that skips the hidden parts. A good survey often also gives you useful information (the state of your system, what it needs, the right frequency). So what it produces - an accurate, specific quote - is the payoff of the survey: a realistic price for a properly-scoped clean of your actual system. This is why the survey matters to you, not just the contractor. So the survey yields a reliable quote for a complete clean. This is general guidance.
No survey is a warning
A quote given without a survey - over the phone, from a photo, or by generic guesswork - is unreliable, and a warning sign. Without seeing your system, the cleaner doesn't really know it, so the quote is a guess. It may be too low: a tempting headline price that rises later when the reality is seen, or that reflects an under-scoped, superficial clean (doing only the visible parts and skipping the hidden ductwork). Or it may be too high: padded to cover the unknowns the cleaner couldn't assess. Either way, it isn't a properly-scoped quote.
And beyond the quote's accuracy, a contractor who doesn't survey before quoting may be one who doesn't do a thorough job - because the survey is the first stage of a proper clean (understanding the system before cleaning it, as covered in the survey-access-clean-certify page). A cleaner who skips the survey may skip the thoroughness. So the absence of a survey is a genuine red flag: it suggests a guessed quote and possibly a superficial clean. Be wary of a firm price given without anyone seeing your system - especially a suspiciously low one. So no survey is a warning - a blind quote is a guess - is the caution: a quote with no survey behind it isn't reliable, and may signal a less thorough contractor. So treat a no-survey quote with caution. This is general guidance.
Insist on a survey
So a good extraction cleaning quote starts with a proper site survey - the cleaner assessing your actual system (its layout, grease condition, access and complications) before pricing - which gives you an accurate, specific quote and a clean scoped to your real system. A quote given without a survey is a guess. So expect, want, and insist on a proper survey before a quote.
In practice: when getting quotes for extraction cleaning, favour contractors who survey your system before quoting (and be wary of those who give a firm price without seeing it). A good survey is a sign of a serious, competent contractor who will scope and price the job properly - and it sets up a proper clean (the survey being the first stage of doing the job right). It also gives you a reliable price and a complete clean, rather than a guessed price and possibly a superficial job. So the survey is in your interest, not just the contractor's. So insist on a survey - a good quote starts with a good survey - is the takeaway: make a proper pre-quote survey part of what you expect from an extraction cleaning contractor, and treat its absence as a warning (as covered in how to choose a kitchen extract cleaning company). So want the survey, and be wary of a quote without one. This is general guidance.
Questions
Yes - a good quote starts with the cleaner assessing your actual system (layout, grease, access, complications), because the right scope and price depend on those specifics; a quote given without a survey is really a guess. Yes - a reliable extraction cleaning quote should be based on a proper site survey. The right scope and price for cleaning your system depend on its specifics - how much ductwork there is, how greasy it is, how it's accessed, and any complications - which the cleaner can only know by seeing your system. So a good contractor surveys first: they come to assess your actual system before pricing the job, so the quote reflects what actually needs doing. A quote given without a survey (over the phone, from a photo, or by guesswork) is unreliable - the cleaner is pricing a system they haven't seen, so it may be too low (and rise later, or under-scoped) or too high (padded for the unknowns). So expect a survey before a quote: it means an accurate price and a clean scoped to your real system. So yes - a proper quote starts with a survey. So yes; without one it's a guess. This is general guidance.
The cleaner assessing your system's layout and extent (the ductwork run), the grease condition, the access (panels, fan location, any needed), and complications (roof fan, awkward route, UV, fire dampers) - building a real picture to scope and price the job. A good pre-quote survey involves the cleaner assessing several things about your specific system. The layout and extent: the ductwork run from canopy to fan - its length, route and configuration - so they know how much there is to clean. The grease condition: how heavy the build-up is, and where - which affects the work involved. The access: how the system can be reached - the existing access panels, the fan's location and access (roof or in-line), and whether more access is needed. And any complications: a roof fan needing height access, an awkward duct route, a UV system, fire dampers, a difficult location. From this real picture of your system, the cleaner can scope the job accurately and give a realistic, specific quote. So a good surveyor looks at all of it (not just glances at the canopy), because all of it affects the clean and the price. So they assess the extent, grease, access and complications. So a proper look at your whole system. This is general guidance.
Because the cleaner is pricing a system they haven't seen, so the quote is a guess - it may be too low (and rise, or under-scoped and superficial) or too high; and a contractor who skips the survey may skip the thoroughness. A quote given without a survey is a warning sign for two reasons. First, it's unreliable: without seeing your system, the cleaner doesn't really know it, so the quote is a guess - it may be too low (a tempting price that rises later when the reality is seen, or reflects an under-scoped, superficial clean that skips the hidden parts) or too high (padded to cover the unknowns). Either way, it's not a properly-scoped quote. Second, a contractor who doesn't survey before quoting may be one who doesn't do a thorough job - because the survey is the first stage of a proper clean (understanding the system before cleaning it), so skipping it can signal skipping the thoroughness. So be wary of a firm price given without anyone seeing your system, especially a suspiciously low one. So because it's a guessed quote and may signal a less thorough contractor. So it means a guessed price and possibly a superficial clean. This is general guidance.
Not necessarily - a survey means the quote is accurate (matched to the real job), which protects you from both a low quote that rises later and an over-padded one; an accurate quote is better value than a guessed one, whichever way it lands. Not necessarily. A survey doesn't make the quote higher - it makes it accurate, matched to the real job. This protects you both ways: from a tempting low quote that rises later (once the cleaner sees the reality) or reflects an under-scoped, superficial clean; and from an over-high quote padded to cover unknowns the cleaner couldn't assess. So a surveyed quote might be higher or lower than a guessed one, but it's realistic - you know it covers the actual work your system needs. An accurate quote is better value than a guessed one, because you're buying a properly-scoped, complete clean at a reliable price, rather than gambling on a figure that may not reflect the real job. So don't assume a survey means paying more - it means paying the right amount for the right job. So no - it means an accurate quote, which is better value. So not necessarily; it means accuracy. This is general guidance.
Be cautious - it means the quote is a guess and the contractor may not be thorough; favour contractors who survey first, and treat a firm price given without seeing your system (especially a low one) as a warning. If a contractor won't survey before quoting - insisting on giving a firm price without seeing your system - be cautious. It means the quote is a guess (they're pricing a system they haven't assessed), which may be too low (and rise later, or reflect an under-scoped, superficial clean) or too high. And it may signal a contractor who isn't thorough (the survey being the first stage of a proper clean). So favour contractors who survey your system before quoting, as a sign of a serious, competent firm that will scope and price the job properly. Treat a firm price given without anyone seeing your system as a warning - especially a suspiciously cheap one (which often means the hidden parts will be skipped). You can reasonably ask a contractor to survey before quoting; a good one will want to. So be wary, and prefer a contractor who surveys first. So treat it as a red flag and favour those who survey. This is general guidance.
Yes - it's the first stage of a proper clean (understanding the system before cleaning it), it can reveal the state of your system and the right frequency, and it sets up honest certification; so a good survey benefits the whole job, not just the price. Yes - a good pre-quote survey does more than produce an accurate quote. It's the first stage of a proper clean: understanding the system (its layout, grease condition and access) before cleaning it means the clean can be planned and done properly, reaching the whole system (as covered in the survey-access-clean-certify page). It can reveal useful information: the actual state of your system, how greasy it is, what it needs, and the right cleaning frequency for your kitchen. And it supports honest certification: a clean planned to the real, surveyed system can be certified accurately (as covered in the difference a detailed survey makes to your certificate). So the survey benefits the whole job - the quote, the clean, the certification, and your understanding of your system - not just the price. This is another reason to value a contractor who surveys properly. So yes - it underpins a proper clean and honest certification too. So yes; it benefits the whole job. This is general guidance.
We survey your actual system before quoting - assessing the layout, grease condition and access - so the quote is accurate and the clean is scoped to your real system, not guessed; the survey is the first stage of a proper, complete clean. Ask us to survey your system and quote properly. This is general guidance.
