Built for Plumbing & Heating Businesses With a Team

At 43 Hours, You're Still Waiting To Answer Your Best Lead. MangoTeq Sentinel Does It In Under Two Minutes.

Steve built an office team specifically to stop missing calls. Last Monday, his ops manager handed him a list of nine leads from the weekend that nobody had called back.

Steve Doyle runs Doyle Plumbing & Heating in Leeds. Fourteen vans. Eleven years trading. An ops manager, three office staff, an answering service for nights and weekends. On paper, the call-handling problem was solved years ago.

Then a cold snap hit on a Friday. Burst pipes across the city. The answering service took message after message. The on-call rota, two technicians covering the whole weekend, couldn't physically get through them fast enough. By Saturday lunchtime the messages had backed up so far that some weren't actioned until Sunday evening.

Steve found out Monday morning. His ops manager had pulled the weekend's enquiry list against what actually got booked... Nine leads, no callback within four hours. Six of those nine had already booked someone else by the time anyone from Doyle Plumbing reached them.

He'd paid for those leads. The team he'd built specifically to handle this hadn't failed because anyone was lazy or careless. It failed because the volume spiked past what a two-person on-call rota and an answering service could absorb in real time. Nobody owned the job of catching the overflow.

This isn't a Doyle Plumbing problem. It's what happens to almost every plumbing business once it grows past the size where the owner personally answers the phone.

MIT and InsideSales.com studied 100,000 inbound leads across service businesses. A lead contacted within five minutes is 21 times more likely to convert than one contacted after thirty minutes.

Most plumbing businesses Steve's size have solved the daytime version of this. Office hours are covered, the office team is good at their jobs. The gap moves to after-hours, weekends, and the busy periods that spike past whatever rota is on duty. The average plumbing business takes 43 hours to respond to a new lead. For a business with a team in place, that average is dragged up almost entirely... by the hours nobody's specifically covering.

The Problem

You Built a Team to Fix This. The Gap Just Moved.

Your office team handles daytime calls well. That's not the issue. The issue is everything outside the hours they're covering, and everything that happens when call volume spikes past what the rota on duty can handle.

An answering service takes a message. Someone has to action it. If that someone is a technician two jobs deep on a Saturday, the message sits. If it's a different technician next weekend, the handling is different again. There's no single person responsible for "every lead gets a reply." It falls to whoever's on shift, and on a bad week, that means it gets dropped.

Emergency leads hit this hardest. A burst pipe at 9pm isn't loyal to whoever answers first. The homeowner is calling the next plumber on Google while waiting for yours to call back. If that's a four-hour wait instead of four minutes, you've paid for a lead your competitor just booked for free.

6:40 PM Friday // Burst pipe call, answering service takes the message

Two technicians on call, both already on jobs

Message sits in the queue.

6:52 PM // 12 minutes later

Homeowner calls the next plumber listed on Google

Competitor answers on the first ring.

6:58 PM // 6 minutes after that

Job booked with your competitor

You paid for the lead. They got the job.

9:15 AM Monday // Office reviews the weekend log

Lead's gone. So are five others from the same weekend.

Too late. Job done. Revenue gone.

Coverage That Doesn't Depend on
Who's On Shift

Sentinel runs alongside your existing office team and answering service, not instead of them. Done for you. No software to install, no staff to train.

The Solution

Steve Now Has Sentinel Running Alongside His Office Team,
Not Instead of It.

Every enquiry, from his website, his Google Ads, his Local Services Ads, his call tracking number, gets a structured response within two minutes, regardless of the time, the day, or who's technically on call. His office team still does what they do during the day. His on-call rota still covers genuine emergencies that need a person. Sentinel closes the specific gap: the overflow, the after-hours window, the busy Saturday where messages stack up faster than two technicians can return them. No new login for the office team. No dashboard the ops manager has to remember to check.

Sub-2-Minute Response, Every Shift Every lead gets a structured reply before they call the next plumber, whether it's 2pm on a Tuesday or 11pm on a Saturday during a cold snap

Done For You, Built Around What You Already Have MangoTeq operates Sentinel. Your office team and your on-call rota keep working exactly as they do now

Multi-Channel, Multi-Source SMS, WhatsApp, and voice. Whichever channel a lead comes in from, Sentinel meets them there immediately

A Number for the Gap You Couldn't See Every previously invisible overflow lead now shows up somewhere, instead of in a bad review three weeks later

Sentinel doesn't replace your CRM, your answering service, or your technicians' on-call rota. It catches what falls outside them. If it underperforms, it comes out without disrupting anything you've already built.

How It Works

Three steps. Nothing your team has to relearn.

We Map the Gap

We review your current call handling, office hours, after-hours, answering service, on-call rota, and show you exactly where leads are slipping through, with real numbers from your own enquiry volume.

We Deploy Around What You Have

Sentinel is built around your existing setup in days, not weeks. No software for your office team to install, no new process for your technicians to follow.

We Cover the Overflow

Every lead that falls outside your team's existing coverage gets an instant, structured response. You see what's being caught. Your team keeps doing exactly what they already do well.

The Outcome

The Team You Built, Finally Covering Everything It Was Meant To.

Sentinel doesn't ask you to add headcount or rebuild your call-handling process. It closes the specific window your team and your rota were never going to cover on their own: nights, weekends, and the busy periods that spike past capacity.

The result: fewer leads going cold for reasons nobody can quite explain, and an actual number attached to what was previously a guess.

Overflow and after-hours leads get the same response speed as daytime ones
Dormant enquiries re-engaged automatically, no manual follow-up required from your office team
Clear visibility into exactly where leads were leaking, instead of finding out from a slow month
Recovery typically exceeds deployment cost within 30–60 days

Steve's team didn't change how they work. The hours nobody owned finally got covered.

Common Questions

Straight answers to what plumbing business owners ask us most.

Most owners believe that, right up until someone pulls the real numbers. The average is 43 hours. Steve's ops manager found out the hard way — nine leads, one weekend. Sentinel removes the guesswork. It replies within minutes, regardless of who's on shift.

Your office team handles daytime well. That was never the issue. The gap is after-hours, and the spikes that outrun whatever rota's on duty that day. An answering service takes a message... it still needs a person to act on it. Sentinel is the part that responds the instant the lead arrives, regardless of who's technically on call.

No. Your rota still covers the emergencies that genuinely need a person on-site. Sentinel catches the overflow — the after-hours window your rota was never going to manage on its own.

No. Every message goes out in your business's name, written the way your team actually talks to customers. Sentinel is a managed service. Not a chatbot anyone configures or notices.

Most businesses this size discover the same thing once we check their numbers: 20–30% of paid leads lost to slow response, not bad leads. A lead that never gets a timely reply looks identical to a bad one from the outside.

Nothing to install. Nothing for your office team to configure. So nothing to unwind if it isn't right. Pricing gets agreed on the call, once we've reviewed your volume. And if we don't hit the agreed minimum of qualified conversations within 60–90 days... we keep working. No extra cost. Until we do.

We map your current call-handling — office hours, after-hours, answering service, rota — against your real enquiry data. Sentinel deploys around what's already there, in days. No new login for your team. Nothing to relearn.

It depends on your lead volume and average job value, so we work it out on the call. Pricing is performance-aligned. We go through the numbers together before anything is agreed.
