Builders work better with rules. Why technical jargon is a warning sign, what four extra tea breaks a day really cost, and how to be the client good builders work hardest for.

This article is adapted from Chapter 6 of Your Seven Step Home Extension Plan by Ashton Paul — the book that shows homeowners how to manage a project and avoid the stresses and strains of the home extension process.

There's a line in Chapter 6 that sums up the whole business of running a building project from your kitchen table: builders are like children; they work better with rules. Without rules, they will only push the boundaries of your patience and frustrate the hell out of you. Most builders have good intentions — it's the lack of contractual structure, plus outside pressures like cash flow and the supply of labour, that forces them off track.

So managing your builder isn't about personality or volume. It's about rules, communication and keeping your own side of the bargain. Here's how the book breaks it down.

Communication: when the talking stops, worry

Builders are famously bad communicators. Is it reasonable for your builder to call you at 8 a.m. — or better, the night before — if the team can't be on the job? Of course. Will he? Not reliably. Roofers and scaffolders are stranger still: if it's raining, don't expect them to turn up, and don't expect a call explaining why. To them it's obvious — it's dangerous to work in the rain — so no call is made. They'll be holed up in the café with a newspaper.

You can live with quirks like that. What you can't live with is silence around problems. When the talking stops, you can be sure problems are developing. One customer came home at 4:30 p.m. to find her young son's bedroom window broken — no warning, no call, and when she rang, the builder denied all knowledge before sending someone round. Nobody breaks a window without knowing. A tradesman had failed to report it, ignoring the security of the property and the glass in a child's bedroom. Your expectations — however unreasonable they may seem — need communicating not just to your builder, but to his staff and subcontractors too.

Jargon is a red flag, not a measure of your intelligence

As a young surveyor, Paul was once sent to a roadworks project in Richmond Park knowing only the basics of road construction. The site foreman started talking gibberish. Rather than nod along, Paul stopped him: "Listen, mate — I have no idea what you just said. In English, can you tell me what you need?" The foreman asked, plainly, for dimensions at one-metre intervals from the road centre to the edge of the proposed pond — and Paul had the drawing back to him within the hour.

The lesson has stuck for decades. Just because you don't understand what a builder is talking about doesn't make you stupid. If a builder speaks to you in technical language you can't follow, he's trying to confuse you. If he can't explain it in terms a six-year-old would understand, then he's the one with the problem. Some of the smartest people Paul has ever met simply ask sharp questions, or rephrase a statement in simple terms for clarification.

While we're on warning signs: all good builders know the framework of building contracts — payments, variations, defects — from working with architects and surveyors. If yours doesn't, he's pretending to be a builder, and you should avoid him. In fact, sensible terms are a filter in themselves: cowboy builders run a mile when you insist on references, a contract and phased payments in arrears. The builders who find your terms unpalatable are precisely the ones you shouldn't be working with. (More on the vetting itself in how to find a good builder.)

Keep your side of the bargain

Here's the uncomfortable question the book asks: guess how many clients are actually ready at 8 a.m. on the Monday morning the works start? Rooms cleared of furniture, kitchen cupboards emptied, garden furniture moved, rubbish gone. The answer is: not many. Be the client who is ready.

From day one, the builder is forming a picture of what you'll be like for the whole contract — and the small stuff has real costs attached:

  • That skip on your drive isn't yours. Contractually it belongs to the builder, who has allowed a set number of skips for your project. Fill it with your clear-out and you've just cost him about £140.
  • "Can you help us move this furniture?" is a morning of paid labour, quietly absorbed.
  • Most builders won't have the awkward conversation about any of this — they'll just let the job start slowly, because experience has taught them to expect it.

The book's estimate: kept to properly, your side of the bargain could see the project finish two weeks earlier. Know that your builder has built in a contingency of his own — two weeks, in the book's typical-project example — whether he needs it or not, and that he needs paying every working week of the year. If your inefficiency stretches the same work over more weeks, he's earning at a lower rate, and you've become a bad customer without ever raising your voice. He will never, ever have that discussion with you.

Don't nag — escalate

If you've had to ask three times, moaning louder isn't the answer — you've already lost your influence. The sequence that works: a gentle reminder first, then put it in writing, then escalate further. You're paying for a job of work — a wholly commercial activity — not asking a child to tidy a bedroom. If it's important enough to raise, it's important enough to write down; if it isn't worth writing down, perhaps it wasn't worth nagging about.

And if you spot a builder cutting a corner or pulling the wool over your eyes — don't turn a blind eye because a confrontation feels like hassle, and don't give a friend-of-a-friend a pass because he came recommended. It's your home and your project, and you're entitled to be completely satisfied at the finish. Getting into a shouting match on site rarely gets you what you want; a clear, firm, businesslike conversation usually does.

The tea break arithmetic

One project Paul watched from close quarters ran four extra 15-minute tea breaks a day. That's an hour a day, five hours a week — and over an 18-week project, almost two full weeks of work lost to tea breaks alone. The team finished weeks behind, to nobody's surprise, on works that could have wrapped up on time with the next project started. Paul's estimate of the opportunity cost: around £10,000.

That's what "small stuff" compounds into. It's also why the ground rules — working hours, breaks, tidying, access — belong in writing before the start, as we covered in the paperwork that protects you. Rules set at the start are house rules; rules invented mid-project are nagging.

Builders hate change — so manage your decisions

Put yourself in the builder's boots for a minute. He's built a timber stud wall, fitted the door lining and plasterboard; the plasterer — a mate — is booked for three days, his last three before his holiday. Then the client changes her mind about the bathroom size. Now the builder either works evenings to stay on track or rings round for a replacement plasterer at a premium, while his mate tells him a story about counting on that money for his holiday. One "small" change; a week of headaches.

Builders hate changes because every change means going back to the drawing board and rescheduling works, labour and materials — and because they're proud individuals who don't enjoy demolishing their own handiwork. You'll inevitably face decisions during the works, so handle them like this:

  • Don't rush them — step away, make a few calls, do some research.
  • Do make them in a reasonable timeframe — and agree what that timeframe is. Paul always asks for a decision timescale, even by email: "It's not urgent, next week is fine" lets him deliver in two days and look efficient; "It's urgent" lets him prioritise.

Be the customer builders want to work for

Have you ever wondered whether you were a good customer? Whether your project is eight weeks or twelve, the profit margins are usually much the same — so what makes a builder choose you, work hard for you, come back for you? An easy job. Prompt payments. Not too many changes. A project that finishes on time so he can move to the next one. A case of beer as a thank-you at the end — and best of all, a recommendation that leads to his next job four doors down the road.

What he does not want, whatever it looks like, is endless tea, biscuits and an over-friendly client chatting to the workers. The builder knows that when his staff get too comfortable, the work rate drops — especially with a less cosy project waiting in the diary. Friendly, firm and businesslike wins every time.

Managing the builder is step six of the seven — it goes wrong when steps one to five were skipped. Our surveyor-led design and build service exists precisely so that the specification, contract and programme are in place before there's anything to manage; the pre-start preparation does the rest. The complete playbook is in Your Seven Step Home Extension Plan (£12.99).

Frequently Asked Questions

How do I manage a builder during my extension?

Set clear written rules from day one and manage against them — builders work better with boundaries, and without them they will push the limits of your patience. Ask for a programme before the works start, hold a weekly meeting against it, keep your side of the bargain (cleared rooms, prompt payments, timely decisions), and escalate issues in writing rather than nagging verbally.

What if I don't understand what my builder is telling me?

Ask him to explain it in plain English — not understanding builder jargon doesn't make you stupid. If a builder speaks to you in technical language you can't follow, he's trying to confuse you; if he can't explain it in terms a six-year-old would understand, the problem is his, not yours. Smart clients ask sharp questions and rephrase things in simple terms.

Why do builders dislike client changes so much?

Because a change means rescheduling works, labour and materials — cancelling the plasterer who only had three days before his holiday, finding a replacement at a premium, and often demolishing work they were proud of. Reduce changes by locking the design down before the start, and when decisions are needed, make them within a reasonable, agreed timescale.

How do I know if my project is running behind programme?

First, you asked for a programme with the quote or before works started. Second, ask the builder directly at your weekly meeting — and don't accept a brush-off. Expect a detailed explanation of where you are against the programme and what he's doing to catch up; a good builder will treat it as a chance to show he's in control.
