The quotes come back and they never match. One is noticeably cheapest, one arrives as a single number on a WhatsApp message, and one runs to a page of line items nobody asked for. The cheapest is cheapest until it is not — and the difference between the three is almost never overcharging. It is scope. This article is about reading the scope out of each quote before comparing the numbers.
To be clear about scope: what installations cost in Pretoria this year is covered in our installation cost guide, and how to spot a finished job that was done badly is covered in our installation mistakes guide. This article sits between them: the paperwork stage, where a good job and a bad one already look different.
What a Complete Quote Contains
A quotable install has a fixed set of parts, and every one of them should be visible as its own line: the motor, named by model and class rather than "suitable motor"; the rack or rail; the plinth and civil works; cabling and conduit; the safety beams, with a count and wired or wireless stated; any access control — keypad, intercom, app module — listed separately; labour; the warranty terms for motor and for workmanship, which are different warranties; lead time; and a payment schedule. A quote that names the actual model lets you check that the motor class matches the gate, which is the single most important engineering decision on the job and the one our sizing guide explains how to sanity-check.
The Line Items That Quietly Disappear
| Missing item | What it saves today | Where it comes back |
|---|---|---|
| Safety beams | One accessory's price | A gate that closes on a car, or a compliance gap at claim time |
| Conduit on cable runs | Half an hour of labour | An excavation through new paving at the first cable fault |
| Plinth spec and curing time | Days off the schedule | Anchor creep, misalignment and rework — the timeline in our curing guide exists for a reason |
| Surge protection | One small device | The first Highveld thunderstorm |
| Battery spec | A smaller battery | A gate that dies two hours into the first stage of load shedding |
| Handover documents | Nothing visible | An insurance or warranty conversation with no paper |
None of these omissions is a scam on its own. Together they are how a quote falls ten percent below the others, and every one of them is a cost that lands after the installer has been paid.
Same Scope Before Same Price
The practical method is to build the comparison yourself. Take the three quotes and list, for each: motor model and class, whether civils are included and to what spec, beams and their type, conduit, surge protection, battery, aftercare and warranty periods, and lead time. Two quotes rarely differ by more than the value of one or two missing rows — and once the rows are equalised, the residual price difference is the real quote, measuring installer margin, travel and professionalism. That is a fair thing to pay a difference for. What is not fair to anybody is choosing between a number and a scope.
Questions That Reveal the Installer
- Who does the civils, and what curing schedule do they work to? An installer with a straight answer here has poured plinths before.
- Which brand, and why this class for this gate? The reasoning matters more than the logo — our brands guide covers what actually differs between them.
- What happens if the motor arrives undersized? You want to hear "we re-spec before ordering", not "we swap it out".
- Is the warranty on the motor only, or on the installation? A mis-set force limit voids neither and breaks either; find out who owns that call.
- What is in the handover pack? Invoice, warranty documents, user guide, and a demonstration of the manual release should all be standard.
Deposits and Payment Terms
Payment structure tells you how the installer sees risk. A deposit against materials ordered is normal; the balance is best linked to something verifiable — installation complete and gate running, then commissioning done and beams tested — rather than to a calendar date. Full payment up front buys you the wrong side of every dispute that follows, and the larger the single up-front share, the more the quote is financing the installer's cash flow rather than your gate. None of this needs to be adversarial: installers who work to stage-linked terms are usually the ones with nothing to hide about sequencing.
Frequently Asked Questions
Is the cheapest quote ever the right one?
Sometimes — when the scope genuinely matches the others, the model is named, and the installer's references and workmanship warranty check out. The exercise above is how you find out whether you are looking at a bargain or a subtraction.
Should I tell installers they are competing?
Yes. It is normal and it improves the documents you get: installers who know a comparison is happening tend to state scope explicitly, which is exactly what you need to judge them fairly.
What if one quote excludes the civils entirely?
Ask why. Ground conditions vary and a genuine site-based exclusion is legitimate; a blanket omission that surfaces as a variation later is not. Get whatever the civil answer is in writing either way.
Do installation quotes expire?
Usually, and legitimately — motor and material prices move. A validity period of thirty to sixty days is normal; treat an indefinite quote as a soft number that will be re-priced at order time anyway.
Comparing quotes is not about finding the lowest number; it is about finding the job you actually want at a price you can see. Itemise the scope, equalise the rows, and the pricing conversation takes care of itself.
