Content Marketing for Builders
One build, documented properly, beats fifty blog posts
The longest research window of any trade on this site
A single storey extension is £19,450. A dormer loft conversion, £17,200. A garden room, £12,850. A garage conversion, £5,900. An internal wall removal with an RSJ, £2,750.
Nobody spends £19,450 on impulse. The typical extension customer thinks about it for six to eight months before they speak to a single builder. They look at other people’s extensions, they wonder what it costs, they worry about planning, they read about party walls at eleven at night, and somewhere in that period they start collecting names.
That window is the whole opportunity. It is far longer than any other trade on this site gets, and it is the only trade where a customer will genuinely read two thousand words before they ring anybody.
Which is why the standard advice — publish a short blog post every week — is precisely wrong for you. You do not need frequency. You need depth, in the places where an anxious homeowner is already looking.
What they are actually searching, months before they call
Not “builder near me”. That comes last, and by then they have usually already decided who to call.
Months earlier they are searching things like: how much does a single storey extension cost, do I need planning permission for a rear extension, what is a party wall agreement, how long does a loft conversion take, what is a building control sign-off, can I live in the house during a build.
Those searches are enormous in volume and almost entirely answered by national portals and content farms who have never built anything. A builder who answers them properly, with real numbers from real jobs and photographs of their own work, competes very well — because the reader can tell instantly which one is written by somebody who has actually done it.
The ratio
An extension is £19,450. Our Booked package is £99 a month — £1,188 a year. One extension covers more than sixteen years.
Content is the slowest thing we do and the longest-lasting. A cost guide written this year is still bringing enquiries in five years, because the question does not change. Compare that with an advert, which stops the day you stop paying, and the case for a builder investing here is stronger than for almost any other trade.
What we’d actually write
One build diary per project. Not a blog post — a page. Before, during, after, with the steel going in, the drain that turned out to be in the wrong place, the building inspector’s visit, and what it cost. Three or four of those and you have the most persuasive content any local builder in your area owns.
A real cost guide. With your numbers, ranged honestly. “A single storey rear extension in this area runs from about £X to about £Y depending on glazing, groundworks and whether the kitchen moves.” Almost no builder publishes this, because it feels like giving something away. It is the highest-converting page a builder can have, because it filters out the people whose budget is a third of the job and pre-qualifies everybody else.
The planning and party wall explainers. These are the two things that frighten homeowners most and the two things they understand least. A clear page on each, written for a nervous person rather than for another builder, gets read and gets shared.
A “what it’s like to live through” page. Dust, noise, the kitchen being out for six weeks, where the skip goes. Nobody writes this and everybody wonders about it.
One page per job type. Extensions, loft conversions, garden rooms, garage conversions, structural openings. Each with its own examples and its own numbers, because they are genuinely different jobs bought by different people.
What good looks like at twelve months
Content for a builder is measured in years, not weeks. Realistically:
- Four to six substantial pages, not forty thin ones
- Three build diaries with real photographs from your own jobs
- A cost guide that ranks for your area and does the filtering for you
- Enquiries arriving that already know roughly what things cost, which shortens every conversation you have
- A visible reason for an architect or an estate agent to send someone your way
The mistakes we see most
Blogging for the sake of it. Twelve two-hundred-word posts about “choosing the right builder” do nothing. One two-thousand-word cost guide does a great deal.
Refusing to talk about money. The single most common and most expensive mistake in this trade. The customer will find a number somewhere; it may as well be yours, with your caveats attached.
Writing for other builders. Nobody outside the trade knows what a padstone is. Explain it or leave it out.
Publishing and never updating. A cost guide with 2023 prices does active harm. It needs revisiting once a year, which is part of what we do.
The first ninety days
Weeks 1–4. We write the cost guide first, because it is the page that will do the most work and it needs your actual numbers rather than a national average. We go through your last few jobs with you to get them right.
Weeks 5–8. Planning permission and party walls — the two fear pages. Written plainly, aimed at a homeowner reading them in bed.
Weeks 9–12. The first build diary, assembled from a job you are running now. Three photographs at three fixed moments and a voice note in the van; we do the rest.
At ninety days the measure is whether enquiries have started arriving with a realistic budget already in mind. That is what the cost guide does, and it changes the quality of every conversation that follows.
Where this lands in Gaffer
The build diary and the job record are the same thing. Photographs, dates, what changed and why all sit against the job you actually ran, so the content assembles from work you have already done rather than being invented afterwards.
Your quote templates carry the real numbers, which is what keeps the cost guide honest and current — when your prices move, the page that quotes them is flagged rather than quietly going stale.
And an enquiry from a cost guide arrives as an opportunity with the page it came from attached, so you know whether you are talking to a garden-room reader or a loft-conversion reader before you ring back.
Questions builders ask
Won’t publishing prices lose me work? It loses you the wrong work, which is the point. Builders who publish ranges consistently report fewer, better-qualified enquiries.
How often do I need to publish? Four to six real pages a year beats weekly filler comfortably. Depth is what this trade needs.
I haven’t got time to write. You are not writing. You are answering questions on the phone for twenty minutes and sending photographs; we write it.
How long before it works? Three to six months for the guides to gain traction, longer for the competitive terms. It is the slowest thing we do and the only one that keeps paying after you stop.
