How should a carpenter price decks and pergolas?
A carpenter has three real pricing models to choose between for a deck or pergola, and only one of them protects the job’s margin when it has this many moving parts. Day rate ties the carpenter’s income straight to hours on the tools and caps how much the business can grow. Flat rate needs near perfect accuracy on every post, joist and roll of decking, or the carpenter wears the loss on a bad day. Shopping list pricing bundles labour, timber, hardware and markup into one price per item, so the client buys a finished deck or pergola, not a list of things to haggle over.
Why does quoting a deck line by line cost the carpenter money?
A deck or pergola has more moving parts than most jobs a carpenter prices: posts, joists, decking boards, balustrade, roofing, flashings, brackets and fixings. Quote it line by line and the client, or the builder they are subcontracting through, treats every single line as negotiable.
The homeowner has priced decking boards at the hardware store. The builder has had three other chippies quote the same job at different day rates. Once the carpenter’s labour cost sits out in the open next to a materials receipt, the conversation stops being about the finished deck and starts being about whether the carpenter’s hourly rate is fair.
What happens when the client can see the carpenter’s labour exposed?
Once labour is shown as its own line, every renovation, fit-out or framing job turns into a negotiation about the carpenter’s time rather than the value of the work. The client starts comparing the carpenter’s day rate to a mate’s day rate, or to what they think the job should take, instead of what the finished pergola or deck is worth to them.
This is how margin disappears a small piece at a time. The carpenter discounts the balustrade because the client thinks it is overpriced, discounts the roof addition because it looks like “just a few more posts”, and by the time the job is locked in, the margin that was built into the original quote has been negotiated away line by line.
What is shopping list pricing for a deck or pergola?
Shopping list pricing is a model built specifically to protect margin on jobs with many parts, and a deck or pergola is exactly that kind of job. Instead of pricing posts, joists, decking and balustrade separately, each component is pre-priced as a bundled item: labour, timber, hardware and markup all folded into one figure, the way a restaurant prices a dish rather than listing the cook’s time and the cost of each ingredient.
The client sees a price for the deck, a price for the balustrade upgrade, a price for adding a pergola roof. They never see the hourly rate or the timber cost sitting underneath it, so there is nothing for them to compare to a hardware store receipt or another chippy’s quote.
What number should a carpenter check before locking in a price?
The number that matters here is the gross profit margin on the job, and it is not something a carpenter checks once a month when the books get done. It is checked at the moment the balustrade upgrade or the roof add-on gets priced, every single time, because that is the point where margin is either protected or given away.
A data first approach means that number comes from the carpenter’s own past jobs, not a guess or a memory of what a deck “usually” costs. Memory tends to remember the easy jobs and forget the one where the retaining wall held up the whole crew for two extra days. The actual numbers, job by job, show which decks and which pergolas are really making money and which ones are quietly eating the apprentice’s wages.
How can AI agents take over deck and pergola quoting?
An AI agent is software that does a job the way the carpenter would do it themselves, using the carpenter’s own prices, wording and rules, and for quoting a deck or pergola that means it can check every part of the job is covered before the quote goes out.
Picture a carpenter whose quoting was slow and manual, done late at night after a full day on site. With so many parts to a deck job, from the main frame down to the brackets and the post caps, it was easy to leave something small off the quote, and then be standing on site without it. An AI agent working from a checklist built for that type of job, covering every material down to the fixings, closes that gap before the quote is sent, not after the timber has already been ordered short.
AI agents also make it simple to offer good, better and best options on a deck or pergola, a bigger footprint, an upgraded balustrade, a pergola roof added on, each priced as its own bundled figure rather than a renegotiation of the carpenter’s day rate.
How does Data First Coaching approach this?
Data First Coaching starts from the carpenter’s own job data through the Trade Business Intelligence, looking at which decks and pergolas actually held their margin and which ones quietly lost it, before deciding whether the real problem is the pricing model, the quote itself, or what happens once the job is on site. Greg Allan puts it plainly: “every single job is pre-priced so you’re not left guessing or missing key expenses.” The how, building the pricing structure and the checklists that make it work, is worked through inside the Academy, with members, because the Trade Business Intelligence is powered by every member who is open minded, innovative and willing to share.
