What changes the price

• The room itself. A small bedroom with sound walls is a different day from a living room with a picture rail, a chimney breast and two colours.
• Stairs, spindles and landings. They take longer than a square room of the same floor area. If they are in the job, say so at the start.
• Preparation. Stripping wallpaper, filling cracks, sanding, and priming stains is often more of the labour than the final coat. A wall that looks “grand” until the paper comes off can change the job.
• Condition. Nicotine, water stains, dark colours under a pale one, and fresh filler that has not been primed all add coats.
• Woodwork. Doors, frames, skirting and banisters are a large share of a proper job. A quote for “walls only” will look cheaper and the room will still look tired.
• How far it is from Omagh. A house in Lisnaskea or Cookstown is not the same call-out as a street in Omagh. The quote should be honest about that. There is no published call-out fee on this site, because it depends on the work.
• The paint. Standard trade paint and a designer tin are not the same cost. If you have already bought a specific paint, say so.

Doing several rooms while the dust sheets are already down is usually better value than booking the same rooms months apart. That is about the setup, not a discount code.

Published UK guide figures

Checkatrade’s painter and decorator cost guide, in the detailed table marked as updated in October 2026, gives these UK-wide ballparks. The guide says they include regular trade paint and labour, and that premium paints cost more. A line of “fast facts” on the same page says a typical day rate of £325, while the table averages the day rate at £300. Treat that mismatch as a reason to use the guide loosely.

Screwfix publishes a wider UK range in its own 2026 guide, on different assumptions: walls and ceilings, only minor preparation, and you move the furniture yourself. Their professional column is £200 to £450 for a small room, £250 to £600 for a medium room, and £350 to £900 for a large one. Source: Screwfix, how much to paint a room.

The gap between those two guides is the useful lesson. “The cost to paint a room” depends on what is included. A number with no description of prep, woodwork and paint is not a quote.

There is no separate Northern Ireland index here

I am not going to invent a Tyrone or Fermanagh average to sit beside those UK figures. Travel, the age of the houses, and how long walls stay damp all change the work, especially on exteriors. For outside paint, the limitation is often the weather rather than the price of the tin. That is covered in exterior paint for damp Northern Ireland weather.

What to tell Martin

On the quote form, the useful details are the town, the rooms, whether paper has to come off, and roughly when you want it done. Photographs on WhatsApp help if the walls are cracked or the stairs are part of it. He will come back with a price for that job. If you are comparing it with a UK guide, compare it with a description, not with a single average.

Interior work is set out on the interior painting page. Paper is separate, because the material is yours to choose: wallpapering.

Martin paints exteriors when the surface is fit and the week will let the coat cure. This is what is worth knowing before you ask for that quote. It is not a product advertisement, and it does not name a brand he is tied to.

Do not paint a wet wall

Render, pebbledash and older solid walls take up rain and let it out slowly. If you seal a wet wall with a film that cannot breathe, the moisture stays behind the paint. The coat blisters, or the damp finds another way out indoors. A breathable masonry paint, sold for exterior render and pebbledash, is the usual specification for those walls. Emulsion from a kitchen or bedroom is not an outside paint, even if the colour is right.

A wall can feel cold and look dry while the core is still wet, especially on the north side, under trees, or on a gable facing Lower Lough Erne or the hills above Gortin and Newtownstewart. If it is wet to the touch, or an older stain is still active, the job waits. Painting it that afternoon does not make you further on.

Green walls need cleaning first

Algae and mould sit on shaded render all over the counties. Paint on top of them does not kill the growth. It comes through, or the new coat lets go. The sequence is wash, treat, let it dry, then paint. North-facing walls and anything under a dripping tree are the usual places. This is ordinary prep, and it belongs in the quote.

Scrape what is already failing

Flaking and chalking paint has lost its grip. A new coat sticks to the flake, and the flake is what falls off. Loose material comes off, bare patches are primed, and cracks are filled before the finish. If you can pull ribbons of old paint off with a scraper, that is the job, not a quick freshen-up.

Timber is a different problem

Fascias, soffits, bargeboards, sills and doors fail at the joints, where water sits. If the wood is soft under a knife, paint will not restore it. The rotten piece needs repaired or replaced first, or you will be painting it again next year. Martin will point that out. Replacing roof timber is not the decorating, and he will not pretend a coat of gloss is a repair.

Windows should be painted so the edges that meet the frame are covered, and they should not be painted shut. Open them while the work is done. It is a small thing and it is how sashes and modern casements end up stuck.

When he will not paint

• The wall is wet, or there is an active leak above it
• Frost is due on a fresh coat
• The surface is crumbling in handfuls rather than holding a coat
• The only available day is in the middle of a wet fortnight

Late spring to early autumn is the realistic season. Even then, a job moves if the weather turns. That is normal in Omagh, Enniskillen, Kesh and the glen. It is not a decorator being awkward.

Colour is the last decision

Very dark masonry on a sunny gable runs hotter and can fade sooner. In this climate the bigger risk is still moisture, not the sun. Choose a colour you can live with on a grey day, because that is most days. Look at it on the actual wall if you can, not only on a chart indoors.

Published UK price guides do include exterior averages. They are national figures with their own assumptions, and they are not a quote for your house. The cost article explains how to read them. For the work itself, see exterior painting, or ask Martin for a quote with the town, what needs painted, and whether it is peeling or only faded. Photos on WhatsApp are the fastest way to show a gable.

What those jobs have in common

Small rooms can take a loud paper. The cloakroom with the burgundy and pink floral works because the room is tiny and the daylight is limited. The same paper across an open living room would be a lot. If you like a maximal pattern, a downstairs toilet or a short stretch of hall is the low-risk place.

One wall is often enough. The willow-leaf bedroom leaves the other walls painted. The dining room with the animal-portrait paper paints the return wall a dusky pink. The pattern does the work. The paint gives the eye a rest and keeps the cost of the paper down, because you are not buying it for every wall.

Halls are being split in half. Floral stripes, mottled papers and stone effects are going above panelling or a painted dado, not from skirting to ceiling. The lower wall takes the knocks from bags and children. Paint on that half can be washed. The paper stays at eye level, which is where you notice a hallway.

Stairs need a paper that can turn a corner. Large repeats and fake stone veins show every seam that drifts. A busy botanical can hide a slight mismatch better than a stripe. Either way, a stairs uses more paper than the floor area suggests, because the drops are long.

Prep, in the order that matters

1. Check for damp. If the wall is wet, stop. Paper hides the mark and then stains or peels. Martin is not there to cover a leak with a floral. The cause needs dealing with first. He does not install damp-proof courses.
2. Strip what is failing. Papering over paper is how bubbles and peeling edges start. The leaf-pattern job in the gallery shows the scarred plaster that can be waiting underneath. That gets filled before anything is hung.
3. Fill and sand. A pattern will not disguise a lump. Side light on a landing shows it. Repairs are part of making the wall good, and they are easier before the paper is up than after.
4. Size or line a patchy wall. Bare filler, old plaster and new skim drink paste at different rates. A sealer or a lining paper gives the finish a flatter base, especially under a pale or lightly textured design. A heavy pattern is more forgiving, but it still wants a sound wall.
5. Same batch. Rolls bought later can differ even with the same name on the label. Order enough for the stairs and the mistakes. A spare roll is cheaper than a seam in a different shade halfway up the hall.
6. Sockets and switches. Plates come off so the paper runs behind them, then go back. The power is off while that is done. It is part of the job, not a finishing shortcut of paper cut roughly around the plate.
7. Match the pattern on purpose. Stripes, florals and stone effects need the repeat lined up. On a stairs the waste is in those matches. A “free match” paper is more economical. Ask before you fall for a large drop that will halve the useful length of each roll.

Choosing between paper and paint

Paint is the simpler finish on a wall that is slightly out of true, and it is easier to refresh in five years. Paper is the finish when you want the room to have a design you cannot get from a tin. Many of the houses in the gallery use both: paper where it earns its place, paint on the panels, the chimney breast, the woodwork and the ceiling.

The photographs are on our work, and the service is described on the wallpapering page. If you already have the rolls, say so when you ask for a quote, and say whether the old paper is still on the wall. That is the difference between a hang and a strip-and-hang.
