Commercial Painting in Camden: In-Hours or Out-of-Hours?

In-hours painting is the cheaper and simpler choice whenever the work can be sectioned off without stopping trade. Out-of-hours painting earns its premium when closing an area would turn customers away or block a fire escape. Most Camden jobs use both. Below is how that choice plays out in practice.

Where the two options actually differ

The paint, the prep and the people are the same either way. What changes is when the work happens, and that shifts almost everything else about the job.

What matters	In-hours working	Out-of-hours working
Trading	Part of the floor is out of use while wet	Space is back in use for opening
Staff	Working around sheeting, towers and wet edges	Desks, stock and IT untouched during the day
Access	You are already open, no extra arrangements	Needs keys or a contact, alarm codes, a lock-up plan
Odour	Smell carries through an occupied space	Building airs overnight before anyone returns
Programme	Fewer calendar days, full working shifts	More calendar days, shorter productive shifts
Cost	Lower	Higher

The rest of this is the detail behind each row.

Disruption to trading and staff

In a shop, café or restaurant, in-hours painting means a section of your floor is out of use while it is wet. Sheeting, a tower and a wet edge take up more room than customers expect, and the space stops looking like somewhere to spend money. According to HSE (2024/25), slips, trips or falls on the same level made up 30 per cent of non-fatal injuries reported under RIDDOR, the largest share of any accident type. Trailing leads and damp floors in a space the public walks through are exactly that risk, which is why trading areas are usually the first thing we move to evenings.

Offices are a different case. Most offices have a floor, a wing or a meeting suite that can be cleared for two days without anyone really noticing. If your team can hot-desk for 48 hours, in-hours working is the right call and the cheaper one. There is no sense paying for night shifts to repaint a room that is empty anyway.

Communal areas in managed blocks sit between the two. Residents use a stairwell at all hours, so the question is not whether people are around but whether they can still get past safely and in the dark.

Access, keyholding and who locks up

Out-of-hours work needs an access plan agreed in writing before the first shift. That covers who holds the keys, who sets and unsets the alarm, whether there is a concierge after six, which lift we can use for materials, and where waste goes at the end of a shift. Managed buildings often add sign-in procedures and a booking for the service lift.

In-hours work removes most of that. You are open, someone is already on site, and the last person out is one of yours rather than one of ours. For an independent shop or a single-tenant office, that alone can decide it.

Keyholding is a responsibility, not a formality. If your lease or your insurer limits who can hold keys or be alone in the building, say so at survey. It changes the programme, and it is far easier to change on paper than at ten at night.

Drying time and odour

Water-based contract emulsion is the reason in-hours working is possible at all. It is touch dry within a couple of hours, takes its second coat the same day and has little smell once the room is ventilated. Walls and ceilings painted on a Tuesday morning are usually fine to work under by Wednesday.

Solvent-based finishes are the problem. Eggshell on doors, frames and metalwork holds its smell longer, needs more time between coats and is the finish most likely to prompt complaints from staff sitting nearby. If your scope includes a lot of woodwork or metalwork painting, that is the part worth pushing to a Friday evening so the building has two clear days to air.

Spraying follows the same logic. Large ceilings and open-plan offices are sprayed because it is faster and gives an even finish, but masking a floor properly and controlling overspray is not something you do around occupied desks. Our spray painting page covers how that is set up.

What night and weekend work really takes

The extra cost of out-of-hours work is not only the shift rate. Every evening starts with protection going down and ends with everything cleared, cleaned and put back so you can open in the morning. That set-up and break-down eats into the productive part of each visit, so the same wall area takes more calendar days than it would in one uninterrupted run.

Light and fatigue count too. Working at height under task lighting, with a smaller crew and nobody else in the building, leaves a thinner margin for error. According to HSE (2025/26), falls from a height caused 31 worker fatal injuries in Great Britain in 2025/26, more than any other kind of fatal accident, on figures HSE publishes as provisional until 2027. Access equipment, stairwell towers and lone-working arrangements get planned at survey, not improvised on the night.

None of that argues against out-of-hours work. It argues for booking it only where it buys you something.

Phasing a job around occupied floors

Most commercial contracts are neither one thing nor the other. The usual answer is a phased programme. Back-of-house, storerooms, empty floors and void units get done in normal hours. The trading floor, reception and stairwells get done in the evening.

In a managed block we take a stairwell in halves so residents always have a lit, clear route past the work. In an office we take a floor at a time and move the affected team for a day or two, which is standard interior painting practice scaled up. In a restaurant we work between close and open, which is a short window and needs a realistic coat count planned into it.

Phasing protects the finish as well as your trade. Splitting a wall across two visits leaves a visible join, so we set phase boundaries at corners, doorways and natural breaks in the surface rather than mid-wall.

Insurance, method statements and permits

Whichever way you go, building management will want paperwork before anyone starts. Expect to be asked for a public liability certificate, a risk assessment and method statement written for your premises, and confirmation of access arrangements. Out-of-hours work usually adds a permit to work, alarm isolation where we are creating dust or spraying, and a named contact who can be reached during the shift.

We carry full public liability cover and produce RAMS for commercial contracts as standard. Getting those documents to your managing agent early is often what decides whether a job starts on the date you booked.

How to decide

Go in-hours if the area can be cleared or sectioned off, the finish is mostly water-based, and no customer has to walk through the work. Go out-of-hours if closing the space costs you trade, the scope includes solvent-based finishes or spraying, or your lease restricts works to evenings. Most premises land on a mix, and the survey is where that gets settled.

Every job is priced as one fixed contract sum with no day rates, and we work evenings and weekends across Camden and North London. See our commercial painting service for what is included, then get in touch or call 07455 705074 to book a survey.
