The Real Cost of Cheap Decorating in London
Why the lowest painting quote in London almost always costs more in the long run. What corners get cut, how to identify them before they become your problem, and how to assess true value.
The arithmetic of cheap
Here is a number worth holding in mind: the labour cost of remedial decoration is typically 40–60% higher than the same work done correctly the first time. Once you factor in the cost of materials for the second attempt, the inconvenience of a second round of disruption, and in some cases the cost of specialist trades to fix structural problems that poor painting concealed rather than solved, cheap decorating is rarely cheap.
This is not a coincidence. It is a predictable outcome of how low quotes are constructed.
What has to give when a quote is low
A decorator submitting a quote significantly below the market rate for the same work has, mathematically, reduced either their margin or their scope. Experienced contractors with full order books rarely cut margins dramatically. What changes is scope — and since the most invisible parts of a decorating job are also the most important, scope reduction is easy to disguise in a simple quote.
Preparation is the first casualty. Surface preparation — washing down, filling, sanding, priming — typically represents 40 to 60% of the total labour on a quality decorating job. It is also the part the client never sees, because by the time the finish coats go on, all evidence of preparation quality is buried beneath them. An experienced decorator can dramatically reduce preparation time and produce a finish that looks acceptable for three to six months. After that, the substrate reasserts itself.
Product substitution is the second. A quote specifying Farrow and Ball Dead Flat or Little Greene Intelligent Matt can be executed with a generic trade emulsion that costs a quarter of the price. The client cannot see the tin once it leaves the van. Products matter: pigment load, binder quality, and the specific formulations designed for challenging environments (mineral damp, historic lime plaster, high-humidity spaces) all affect long-term performance.
Coat counts are the third. Two coats of a quality product over a properly primed surface is the minimum for a durable finish. One coat over inadequate preparation is cheaper to deliver and often looks similar when the decorator packs up their tools. Six months later, it does not.
What remedial work actually costs
To ground this in reality, consider some typical remedial costs in London (2026 rates):
- Re-preparing and repainting one reception room after a failed finish: £900–£1,600, depending on the extent of surface repair required before repainting
- Stripping and repainting a front door where the previous finish was applied without correct preparation and has begun to peel: £350–£600, including stripping, filling, priming with Zinsser Bulls Eye or Rustins Stain Block, and two finish coats
- Refinishing sash windows where paint was applied over unprimed bare wood or previously failing paint without stripping: £180–£350 per window
- Replastering before repainting where moisture was painted over rather than resolved, causing the new plaster to fail: £600–£2,000 per room, before any decoration
None of these costs are recoverable from the original contractor in most cases without litigation, which is rarely proportionate.
The corners you won't see until it's too late
Beyond preparation and products, low-cost contractors frequently cut corners that are not visible at all during or immediately after the job:
- Window joints filled with silicone rather than resin filler and sanded smooth: looks fine initially; silicone cannot be painted over reliably and will begin to peel within months
- Radiators painted without draining and removing from the wall: paint applied over the fixing brackets and valve areas will crack as the radiator expands and contracts, and the areas behind the radiator are simply not decorated
- Bare MDF edges on kitchen units sealed with emulsion rather than an appropriate primer: MDF absorbs moisture rapidly without proper sealing; the edge swells, the paint lifts, and the unit is effectively damaged
- Previously damp walls painted over without addressing the source: the new paint fails within six to twelve months, and the underlying damp problem has been given time to worsen
How to assess value rather than price
The right question to ask about a decorating quote is not "is this cheap?" but "do I understand what I am paying for, and does it represent fair value for the outcome I want?"
Indicators of genuine value in a higher-priced quote:
- Itemised schedule of works with named products and coat counts
- Preparation scope described in detail
- Clear start and end dates with a programme
- References from completed work of comparable scale and type
- Verifiable insurance and, ideally, trade body membership
A quote that offers all of these things at a price modestly higher than the cheapest option is almost always the correct choice.
