Cheap vs expensive strip-out quotes: what is the real difference?

Why do quotes for the same job differ so much?

Strip-out quotes differ mainly because each contractor has priced a slightly different job. One has included carrying every bag down four flights; another has assumed the lift. One has allowed for sorting waste into fractions and delivering it to an authorised facility; another has written "rubble removal" without saying where it goes.

Real efficiency differences between competent contractors exist, but they are modest. When one figure is dramatically lower, the first question is not "how are they so efficient?" but "what is missing?". The second question is whether the higher quote includes things you actually need.

What do low quotes typically leave out?

The items below are the usual reasons a strip-out quote looks attractive on paper. Each one is a real cost that someone will pay, either you later or the neighbours and the environment.

When is a higher quote justified?

A higher quote is justified when it buys something you can see and check. Typical examples are detailed protection of a marble staircase or a shared lift, an extra person to carry rubble where there is no lift, careful hand work next to elements that stay, or a precise allowance for sorting fractions such as plasterboard, metal and wood separately.

It is not justified by vague words. "Premium service" or "full management" means nothing unless the quote lists what is done. Equally, a high figure built on very generous assumptions about hidden problems can be as unhelpful as a low one built on optimistic ones. You want a quote whose assumptions are written down, so that you can see which side it errs on.

How do unclear scopes turn into extras?

An unclear scope is the most common way a low quote becomes an expensive job. If the quote says "remove bathroom", and the tiles turn out to sit on a thick mortar bed over an older floor, the contractor can reasonably argue that lifting two layers was not included.

The fix is simple: describe the job room by room and layer by layer, and make the contractor say what is in and what is out. Write down what happens if something unexpected appears, such as a pipe that nobody knew about or a panel that may contain asbestos. A good quote names those situations and explains how they will be handled, even if it cannot price them in advance. Our post on mistakes owners make with kitchen and bathroom strip-outs shows the scope gaps we see most often.

Which questions make quotes comparable?

Send the same questions to every contractor and ask for written answers. That alone usually reveals why the figures differ.

1. Exactly which elements are removed in each room, down to which layer?
2. How does the rubble leave the building: lift, stairs, chute, container on the street, van?
3. Is a permit for occupying the public road needed, and who requests it?
4. Where does the waste go, how is it sorted, and will I receive the delivery receipts?
5. What protection is provided for common areas and for elements that stay?
6. What happens if asbestos, a structural element or hidden services appear?
7. Which VAT rate is applied, and is it shown on the quote?

How should a remote owner judge a quote?

If you live abroad, a quote has to do more work, because you cannot pop round to check. Look for a contractor who asks questions before pricing: which floor, which access, what stays, what the community allows. A quote that arrives without any questions has probably been guessed.

It also helps to agree from the start how you will be kept informed, for example photo updates by WhatsApp at each stage, and who has the keys. Our interior demolition service is organised so that owners can follow the job in English from wherever they are, and for shops and offices the commercial strip-out page explains the extra points a landlord or tenant should agree in writing.

Are there price myths worth ignoring?

A few beliefs about strip-out pricing lead owners to the wrong quote. The first is that a strip-out is "just labour", so any crew with hammers will do. In reality the expensive mistakes come from what is not seen: a pipe broken inside a wall, a partition that was quietly holding up a slab, rubble that never reached a legal facility.

The second myth is that a fixed lump sum protects you completely. A lump sum is only as solid as the scope it describes; if the scope is vague, the extras are simply postponed. The third is that asking for a visit makes the quote more expensive. A visit, or a good set of photos and a video, usually makes a quote more accurate, and accuracy is what keeps the final bill close to the first figure.

So which quote should you choose?

Choose the quote you understand best, not the lowest or the highest. The right one has a clear scope, explains access and waste handling, names the risks, states the VAT rate and comes from someone who asked about your property before writing a figure.
