Every new pool starts a backyard project. Knock first.
Each week, Firstknock sends you the homes in your area that just got a pool permit, and tells you when to knock. The pool builder already sold the job. The fence or screen enclosure, the pavers and the landscaping are still up for grabs.
Sample data in this preview
How it works
Building permits are public record. We read them for you, keep the ones that matter to your trade, and hand you a ready-to-send postcard for each one.
Pick your trade and area
One company per trade in each area, so your leads stay yours.
Get Monday’s drop
New permits arrive by WhatsApp and email, with the address, the project and the best week to reach the homeowner.
Reach them before anyone else
Send a postcard with your logo in one tap, follow the door-knock route, and mark the jobs you win.
Knock when they’re ready to buy
A pool takes weeks to build. We track when each pool was permitted and flag the weeks when your trade is usually needed: before final inspection, when the pool needs a safety feature to pass.

From permit to paid, in one place
Finding the lead is only the start. Firstknock handles the slow parts so you can spend your day building.
An estimate before you visit
We measure the backyard from county parcel lines, so you see the fence run and a price range for each material before you knock.
A page made for the homeowner
The postcard’s QR code opens their own estimate, where they pick a material, book a free measure in your calendar and chat with you on WhatsApp.
Paperwork and materials done
Get the fence permit packet, the HOA request letter and a materials list for your supplier, prepared for that address.
Deposits paid online
Homeowners pay the deposit by card from the same page, so you can order materials the same day.
Pool builders who send you work
See which pool builders are busiest in your area and introduce yourself. One good builder relationship brings jobs every month.
Reviews that win the next job
When the job is done, we ask the homeowner for a Google review in their language.
Runs on WhatsApp
No new app to learn. Your leads arrive on Monday as a WhatsApp message in English or Spanish. Reply to ask for more, and an assistant answers homeowners for you, day and night, then hands the conversation to you.

Questions
Where do the leads come from?
From building permits, which cities and counties publish as public record. We collect them, keep the ones relevant to your trade, and add what you need to act.
Is it legal to contact these homeowners?
Yes, by mail and in person. Permit records are public. We don’t sell phone numbers or send texts to homeowners. Some neighborhoods limit door-to-door visits, so we flag HOA communities we know about.
How many leads will I get?
It depends on your ZIP codes and the season, since pool permits peak in spring. Check your area above to see a recent monthly count before you sign up.
What does “exclusive” mean?
No other company in your trade receives leads for your ZIP codes while you’re subscribed. A landscaper and a fence company can share an area because they don’t compete.
Do I need to install anything?
No. Leads arrive on WhatsApp and email, and the app works in your phone’s browser.
