Deck Builder Leads: What They Cost and How to Reply Fast With AI

Paid deck leads are worth buying only when the price per lead sits below what a lead is worth: job profit multiplied by your close rate and your lead-to-visit rate. Reply within about 15 minutes in working hours, because Thumbtack's own help says faster replies improve your chances of being hired.

That 15 minutes is a working rule, not a platform figure: the help pages checked for this tutorial give no time target. What matters more is knowing your own numbers. At $60 a lead, a reply habit that books one visit from every 17 leads is a poor buy, while the same leads answered in minutes might book one visit from every seven. Every lead price, rate and profit figure from here on is illustrative; replace them with your own after four weeks of tracking.

How each lead source charges, from the vendors' own pages

Platforms change their pricing often, so this table records what each vendor's own pages said in October 2026 and what to ask before you spend.

The most a deck lead can cost you before you lose money

Every paid lead is a bet that it turns into a visit, and a visit into a job. The break-even price per lead is the profit one visit brings, multiplied by the share of leads that become visits:

Break-even price per lead = job profit x close rate x lead-to-visit rate.

Take an average deck job that earns $3,600 in gross profit after materials and crew labour, with one visit in four ending in a win. Each booked visit is then worth $900 on average. Now the effect of reply speed, for a marketplace where leads cost $60 on average and you buy 40 a month. If you reply the next day, 6 per cent of leads become visits. If you reply within 15 minutes, 14 per cent do.

The visit counts are monthly averages over several months, which is why they carry decimals. The same $60 lead loses money at the slow rate (the $54 break-even sits below it) and earns well at the fast rate (the $126 break-even sits above it). Nothing about the platform changed between the two columns. Only your reply time did, which is why speed is the first lever to pull before you drop a platform.

Cost per booked visit, source by source

Run the same arithmetic for each channel, with its own spend and lead-to-visit rates. Own-site enquiries usually come from people who searched for you by name or chose you from a map listing, so assume they convert better, but their cost is the upkeep and ads that bring them in.

Add the visit itself before you judge a channel. A visit that takes 90 minutes on site plus an hour of travel and writing up, valued at $45 an hour, costs $112.50, call it $113. The fast-reply marketplace then costs $429 + $113 = $542 per booked visit, and the slow one $1,000 + $113 = $1,113. A free enquiry still costs that morning, so include the visit time whenever you compare a paid channel with a free one.

Compare each figure with the $900 a visit is worth. With visit time added, the slow-reply marketplaces cost $1,113 and $913 per booked visit, both above $900, while the own site stays well under at about $252 ($139 + $113). At the fast rate all three are profitable, the marketplaces by a smaller margin. Two lessons follow. First, a marketplace is not a bad channel, it is an unforgiving one: it punishes slow replies. Second, spending on your own site before buying more leads is usually the better first move, provided it produces enquiries at all.

A reply standard for a crew that is busy on site

A deck crew cannot be at a phone all day, so write the standard down in terms of who does what, not just a time:

• Instant acknowledgement. Every web form and, where the platform allows, every message gets an automatic holding reply, so the homeowner knows it arrived.
• First real reply in 15 minutes, in working hours. One named person owns it. Put alerts on their phone and agree two or three daily slots when they will check, such as the start of the morning, lunch and the end of the day, with the AI draft waiting for them.
• Evenings and Sundays. An automatic message that promises a real reply by a fixed time the next morning, then keep that promise.
• Decline fast. If a lead is outside your range, say so straight away inside the platform rather than leaving it unanswered, and check in the Pro app how a declined lead counts towards your response record. Two sentences do it: "Hi [first name], thanks for thinking of us. Ground-level patios are outside what we build, so a paving firm will give you a faster, better answer. Good luck with the project, [your name]."
• Work the leads where you are the only pro contacted first. Where a platform shows that a homeowner has contacted only you so far, nobody else is in the race yet, so that reply goes before the rest.

Here is a holding message you can set up once. Adapt the hours to your own, and keep it short:

Hi [first name], thanks for your deck enquiry, it has reached us. We are on site until 4 pm, and one of us will reply properly within the next 15 minutes. If it is after hours, you will hear from us by 9 am tomorrow. In the meantime, a photo of the area would help us give you better advice.

Phone calls need the same standard. If you miss a call from a number you do not know, an automatic text such as "Sorry we missed you, we are on site building a deck. Reply here with the details or tell us a good time to call back" keeps the enquiry alive. Quo, a business phone app, lists auto-replies on all three of its plans and describes them as pre-set replies to texts, missed calls and voicemails; send a test call to your own number before you rely on the wording and timing.

If you use Thumbtack's own automatic first reply, or are weighing it against a separate tool, the Thumbtack Front Desk comparison covers the trade-offs.

Six facts every deck enquiry must give you before a visit

The replies that book visits ask a few precise questions, not ten vague ones. These six decide most of the price and the visit:

1. Approximate size. Length and width, or "big enough for a table for eight". Price scales with area.
2. Height above the ground. It drives steps and railings, and permit and inspection rules often change with height, so check the rules where you work.
3. Attached to the house, or freestanding. The connection to the house changes the scope and the risk.
4. An old deck to remove. Disposal is a cost, and hidden rot in the frame or footings is a common surprise.
5. Material and budget comfort. Timber and composite sit in different price bands, and a customer who says "around 15k" is giving you a range to test.
6. Timing. Whether they need it done before an event or a season shapes your schedule and your honesty about it.

Ask for two photos too, one wide and one low down showing the posts or underside. A photo often saves a visit that was never going to turn into a job.

AI draft, human send: a saved-project routine

Create a saved project in ChatGPT or Claude (a ChatGPT Project or a Claude Project keeps instructions and files together), and paste in the instructions below once. After that, each enquiry takes seconds: paste the homeowner's message, nothing else, and read what comes back. Leave out phone numbers and addresses.

You help a small deck company reply to new enquiries. For each message I paste:
1. Fill this table from the message only: size, height above ground, attached or
   freestanding, old deck to remove, material, budget, timing. Write "not stated"
   where the message does not say.
2. Pick the three most useful missing facts and write them as short questions.
3. Draft a friendly reply under 120 words that asks those questions, asks for two
   photos, and offers two visit slots: [slot 1] and [slot 2].
Rules: never quote a price or a price range. Never promise a start date, a permit
outcome or a material's lifespan. Sign off as [your name]. Use "[first name]".

Try it on a typical enquiry: "Hi, we want to replace our old back deck, roughly 12 by 16, off the back door and about 3 feet off the ground. Thinking composite. Hoping to have it done before June. Budget around 15k?" A sample result:

Size: about 12 x 16 ft. Height: about 3 ft. Attached to the house: yes, at the back door. Old deck to remove: yes, implied by "replace". Material: composite, brand not stated. Budget: around 15k. Timing: before June. Missing: condition of the existing frame and footings, steps or railing, access for deliveries. Draft: "Hi [first name], thanks for getting in touch. To book the right visit, could you send two photos of the deck, one wide and one showing the posts? Are there steps down to the garden, and is the railing staying or going? I can visit on [slot 1] or [slot 2] to measure and talk options. A price after a visit is more reliable, because the frame and footings change the scope. [your name]"

Two things to fix before sending. The draft ignores the June deadline, which is the customer's main constraint, so add one honest line about when you could actually start. And the table says the old deck is to be removed, which is a guess from the word "replace": confirm it in the reply or on the visit rather than letting it harden into an assumption in your quote.

The difference a good reply makes shows best side by side. Before: "Hi, thanks for your enquiry. We do decks. Please call us on [number] to discuss." That asks the homeowner to do the work, shows no sign that you read the message, and offers nothing to say yes to. After: the draft above, which proves you read the details (12 by 16, about 3 feet, composite, June), asks three questions a person can answer from a phone and offers two slots. The second reply takes thirty seconds to answer. The first needs a phone call that many homeowners never make.

Many homeowners attach photos. A chat assistant can describe what it sees, such as a railing style, a set of steps or a stained board, and that helps you decide whether to visit this week or ask for another angle. Treat it as a first read, not a condition survey, because rot and footings cannot be judged from a picture. ChatGPT accepts images up to 20 MB each, and free accounts are limited to 3 file uploads a day, so a busy week of enquiries may outgrow the free plan.

Here is how the mistake looks when the rules are missing. An owner leaves out the "never quote a price" line, and the assistant answers a similar message with "a composite deck of that size usually costs between X and Y". The homeowner anchors on the low end. The visit finds rotten joists and footings, the true price lands above the range, and the customer now feels misled before the first conversation. The rule costs one line in the instructions.

Quiet leads: a follow-up sequence over two weeks

Most enquiries go quiet after the first reply. A sequence of short, different messages recovers some of them, and AI can draft each from the original thread. Keep every message to one clear ask, and stop when the homeowner answers or declines. For a longer pattern that fits open quotes after a visit, see the remodelling follow-up sequence tutorial.

1. Day 1, no reply. "Hi [first name], did the photos of the deck come through? Even a phone picture is enough for me to give you useful advice."
2. Day 3. An easy question: "Is the timing still before June? If so, I'd book the visit this week to keep your slot."
3. Day 7. Two concrete visit times, offered as a choice.
4. Day 14. A closing note: "I'll close your request for now. Message me any time you're ready and I'll pick it up."

The last message matters more than it looks. It ends the sequence politely, and a share of homeowners reply to it because it removes the pressure.

Spring surge: when to switch paid leads off

If your demand is seasonal, as deck work usually is, a busy spell is exactly when paid leads waste money. A lead that arrives when your next free visit slot is three weeks away is a lead you will answer slowly or turn down. Set a rule such as: when the next free visit slot is more than ten working days out, cut your lead price on Thumbtack with the slider, narrow your job preferences, or pause; for Bark, buy small packs because credits expire after three months, so a big pack bought in a quiet spell may go unused in a busy one.

Replies also need to tell the truth about timing. "Our next available visit is on [date]" is a better message than a vague "soon", and homeowners with a real deadline will tell you whether they can wait.

Four weeks of tracking on one page

Everything above depends on your own numbers, so keep a sheet with one row per lead and these columns: date, source, lead price, minutes to first reply, visit booked, quote sent, job won, and job profit. A few filled-in rows show how it looks:

After four weeks, group the rows two ways: by source, and by reply time (under 15 minutes, 15 to 60 minutes, over an hour). The first grouping shows which channel books visits; the second shows whether speed is really driving the result in your business. If the fast group books no more visits than the slow one, speed is not your problem and the leads or the first message are. For a wider view of getting more leads as a builder, the 30-day lead plan puts paid leads next to the free routes.

Questions deck builders ask about paid leads

Should I reply to a lead inside the platform or by phone?

Reply inside the platform first, because a reply sent by text or email outside it may not register as a response there, and Thumbtack's help says faster responses improve your chances. Follow each platform's rules on contact details, and once the homeowner has answered, use whichever channel gets a visit booked fastest.

Can AI answer deck enquiries without me checking them?

Start with draft-only. A reply that quotes a price from a two-line message, or promises a start date or a permit outcome, costs more than the minutes it saves. Let AI summarise the enquiry and draft the reply, and have one named person read and send it. Review that rule after a month of results.

What is a fair cost per booked visit for a deck company?

There is no universal figure, because it depends on your job profit and your close rate. Multiply them: a $3,600 profit and a one-in-four close rate makes a visit worth $900 on average. Pay well below that, leaving headroom for your own time on site, and track the number by source.

Do I need a CRM to chase quiet deck leads?

Not at first. Under about thirty enquiries a month, a spreadsheet with a column for next action and a calendar reminder does the job. Move to a CRM or a job app when you are missing follow-ups, not before, and check that it can record the lead source and the time of your first reply.
