Painting Scope Gaps Between Trades: Who Paints What

Every construction project has a small number of surfaces that nobody clearly owns. They are not in anybody scope because each trade assumed another had them, and they surface at the worst possible moment, which is when the building is nearly finished and somebody notices they are the wrong colour or not painted at all.

Whoever is standing closest with a brush usually ends up doing them. On new work the sequencing side of this is covered in painting new construction versus repaint. This is about the boundaries themselves and how to settle them before they cost you a week.

The gap is a document problem, not a site problem

Scope gaps feel like site arguments and they are almost always created months earlier, in the way the documents were assembled. Specifications are written trade by trade, in separate sections, often by different people adapting different master documents. Each section describes what that trade supplies. Nothing in the structure requires the sections to add up to the whole building.

The organising framework makes the boundary visible if you look for it, since work is grouped into divisions by trade, and the MasterFormat standard is how that grouping is defined. What it does not do is force anybody to check the seams between one division and the next.

So the useful mental model is not who should do this, it is which section says so. When two sections both describe a surface, that is a conflict and somebody must choose. When neither does, that is a gap, and whoever fails to price it pays for it.

Doors and frames, the argument that never ends

This is the most common gap on interior fitout work and it has several separate parts, each of which can land differently.

Hollow metal frames usually arrive shop primed, not finished, which means somebody paints them and it is normally you. Wood doors may arrive factory finished, in which case nobody paints them, or unfinished, in which case they may be finished in a shop or on site. Metal doors follow the same pattern as frames. And the edges of doors, particularly the top edge, are the single most frequently missed surface in the trade.

Read the door schedule and the door hardware section together with the painting section, because the answer is usually distributed across all three. Where the door schedule says a door is factory finished and the painting section says paint all doors, that is a conflict rather than a gap, and the resolution is worth having in writing.

Price the frames separately from the doors on your worksheet even when both are yours. They are different production rates and they frequently happen at different times, and separating them means a change to one does not require repricing the other.

Shop primed, factory finished, and the words in between

Three phrases describe what arrives on site and they mean quite different things to your labour.

Factory finished means the item arrives complete. Your only involvement is protection and, if you are unlucky, touch up of damage caused by handling, which is somebody else responsibility and is worth excluding explicitly.

Shop primed means a primer has been applied under controlled conditions and finish coats are yours. That is straightforward provided the primer is compatible with what you are applying, which is not automatic and is worth confirming rather than assuming.

Prefinished, mill finished and pre coated are looser terms that can mean any of the above depending on who wrote them. Where one of those words appears, ask what it means for this item on this project. The answer decides whether an item is a protection line or a full painting line, and those are not close in cost.

Drywall level, and the finish that shows what was skipped

The boundary between the drywall trade and the painting trade is not a surface, it is a standard, and it is the gap that generates the most rework.

Drywall is finished to a stated level of smoothness. Your coating either conceals what was achieved or reveals it, and higher sheens and critical lighting reveal a great deal. When a wall looks poor under the finish coat, the argument that follows is about whether the substrate was inadequate or the coating was inadequate, and it is very hard to win once the paint is on.

Two protections. Check the required drywall finish level in the drywall section rather than in yours, and check whether it is compatible with the sheen you have been told to apply. And inspect the substrate before you start, in the areas that will be lit critically, because in most specifications commencing work is treated as acceptance of the surface.

Where the substrate is not right, say so in writing before priming. The cost of an extra skim by the trade responsible is trivial compared with the cost of you sanding a finished wall.

Mechanical, electrical and the open ceiling

In any space with an exposed ceiling there is a large quantity of ductwork, pipework, conduit, hangers, sprinkler pipe and structure overhead, and whether it is painted is one of the most expensive open questions on the job.

Three possibilities exist. The items are factory finished and left alone. They are painted by their own trade before installation. Or they are painted in place by you, which is slow, awkward and usually done with a sprayer and a lift.

Read the general notes on the finish schedule, which is where the instruction to paint exposed services usually hides, as how to read a room finish schedule sets out. Then read the mechanical and electrical sections for any statement about finishes on their own equipment. Where nothing in either place answers it, ask, because the difference between painting an open ceiling and not painting it can be a larger number than the walls.

Sprinkler heads and life safety devices are usually excluded from painting for regulatory reasons and painting them can be a genuine compliance problem, so that exclusion belongs in your bid regardless of what the documents say.

Millwork, cabinetry and site applied finishes

Joinery and cabinetry are normally finished in a shop, because the result is better and the conditions are controlled. The gaps appear at the edges of that arrangement.

Scribe pieces, filler strips and site cut trim are made or adjusted on site and cannot be shop finished. Somebody has to coat them, on site, to match a shop finish, which is difficult and is rarely priced. Exposed backs and undersides of built in units may or may not be finished. And where a shop finish is damaged during installation, the repair is skilled work and is not an ordinary touch up.

Ask specifically about site applied finishing of millwork accessories. It is a small quantity of very slow work and it is regularly assumed to be included in a wall rate.

Metalwork, railings and the shop coat that arrives damaged

Structural steel, railings, balustrades, gates and miscellaneous metal usually arrive with a shop applied primer or a shop finish. The shop coat is almost always damaged during transport, handling and installation, and welded connections are bare by definition.

Who makes that good is a genuine gap. The metal trade will say their scope ended when the item was delivered. The painting section may say nothing about touch up of shop coats at all.

Where the item was welded on site, the repair is not touch up, it is preparation and coating of bare metal to a standard, and it needs pricing as such. Take a position in your bid: either it is excluded, or it is included on a stated assumption about the extent of damage, with a unit rate for anything beyond that, using the approach in painting bid alternates and unit prices.

Who makes good after whom

Making good is the gap that keeps producing work after you have finished, and it is a sequencing problem as much as a scope one.

The pattern is familiar. You finish a floor. Other trades return to complete their work, install fittings, chase a fault or repair something. Your finish is damaged. Somebody asks you to come back.

The contract position is usually that damage caused by another trade is that trade responsibility, and the practical position is usually that you are asked to fix it because you are the only one who can. Both can be true, which is why the useful step is not to argue the principle but to agree the mechanism in advance: you return, the work is recorded, and it is charged to whoever caused it or to the contractor.

Photograph each area at completion, dated. That record is what converts an argument about who caused the damage into an administrative matter, and it is the same evidence that protects you against a deduction appearing on a payment certificate months later. The cost of getting this wrong repeatedly is quantified in painting callback and rework costs.

Quality standards, and the boundary they draw

Some gaps are not about which surface but about how good. Where a specification says a finish must be free of defects without saying what a defect is, the boundary between acceptable and rejected is somebody opinion, and that opinion is formed while standing in a nearly finished building.

The defence is to name a standard rather than an adjective. Industry bodies publish descriptions of finish quality that give both sides a shared vocabulary, and the Painting Contractors Association maintains industry standards for exactly this purpose. A bid that says the work will meet a named standard has drawn a line. A bid that promises a high quality finish has not.

Your own internal checking should use the same language, which is what the painting quality control checklist is for. Consistency between what you promised and what you inspect against is what makes the promise defensible.

Settling a gap during the bid rather than on site

Every gap identified before the deadline is cheap. Every gap identified afterwards is a negotiation you enter from behind.

Work through a boundary list while you read the documents: doors and frames, exposed services, millwork accessories, metalwork touch up, making good, and anything shop finished. For each one, write down what the documents say, and where they say nothing, decide whether to ask or to state an assumption.

Ask about the expensive ones and state assumptions about the cheap ones. A question submitted in the bid period returns a written answer issued to everybody, which removes the risk entirely rather than allocating it, and the wording for the rest belongs in your qualifications, as painting bid exclusions and clarifications describes.

What to do when it appears on site anyway

Some gaps survive every check, because a building contains more boundaries than any list covers.

When one appears, the sequence is the same every time and the order matters. Stop before doing the work. Establish in writing that it is not in your scope, referencing your bid. Offer to do it, priced. Then wait for an instruction.

Doing it first and raising it afterwards is the mistake, and it is an easy one to make because the work is often small and the crew is standing right there. A surface painted without instruction is a surface you have donated, and the pattern repeats: once a contractor learns that the gaps get absorbed, more of them will find their way to you. Where a gap is genuinely large, the change order process exists for it, as how to handle change orders on a painting job sets out.

Frequently asked questions

Who paints hollow metal door frames

Usually the painting contractor, because they arrive shop primed rather than finished. Confirm it against the door schedule and the painting section rather than assuming, since some projects specify a factory finish instead.

Am I responsible for touching up shop finished items

Only if the documents say so. Damage during delivery and installation is normally the responsibility of whoever caused it, but the request will still come to you, so a stated position in your bid saves the argument.

What if two specification sections both cover the same surface

That is a conflict rather than a gap, and most contracts contain a precedence clause deciding which document governs. Where the answer is unclear and the money is material, ask during the bid period.

Should I paint sprinkler heads to match the ceiling

No, unless a manufacturer approved factory finish is specified. Coating a sprinkler head can affect how it operates and is generally prohibited, and it is worth excluding explicitly rather than leaving to judgement on site.

How do I handle a gap the contractor insists is mine

Ask them to point at the document that says so. If they can, it is yours and the conversation is over. If they cannot, offer a price. Either way the exchange should be in writing, and it should happen before the work rather than after.

Do these gaps exist on residential work too

Yes, in smaller form, and the same discipline applies. The difference is that a homeowner has no other trades to blame, so the boundary is between what you said you would do and what they assumed, which makes a written scope the whole defence.
