Andrei's Tuesday night.

Before 5 Minute Estimate.

9:30 PM

Still at the desk

Family's watching TV. Mates are at the bar. Andrei is measuring drawings by hand. Again.

Next day

"Used someone else"

The client needed the quote faster. Another builder quoted same day. Job gone.

Weeks later

Wrong materials, wrong time

Nobody told the client when to order tiles. Delivery late. Programme blown. Margin gone.

⚡ Then Andrei found 5 Minute Estimate
At the meeting

Uploads from his phone

Drawings and meeting notes uploaded before he's left site. Still shaking the client's hand.

5 minutes total

Client gets everything

Branded estimate plus a full risk schedule — sent in one crisp email.

That evening

Signed. Pub time.

Impressed by the speed, client signs today. Andrei's at the bar with friends.

No card required · Launches June 2026

Why speed matters

The first builder to reply usually wins.

Clients send drawings to 5 different companies. The one who replies first — with a proper, branded estimate — wins before competitors even open the email.

Got the lot. Reading through now — a couple of quick questions before I run it:
  1. Underfloor heating — extension only or kitchen/bathroom too?
  2. Finishing materials — who supplies tiles, sanitaryware, kitchen, flooring?
  3. Provisional sums — any specialist items the client hasn't decided on?
UFH throughout. Client supplies tiles + sanitaryware — we supply everything else. No provisional sums yet.

Got it. Running through the drawings + structural calcs now. ETA 4 minutes.
19:03
— 4 minutes later —
Done. Couple of things I picked up first:
  • Drawing discrepancy: ground floor on building regs shows 1m more depth than planning drawings. Needs clarifying before tender.
  • Build-over agreement — not in pack. Public sewer runs under proposed kitchen extension.
  • Party wall notice — neighbour to the east, no notice served yet.
  • Steel beam B2: structural calc spec doesn't match what's drawn on the GA. Flagged for SE review.
Estimate + risk schedule attached.

What this costs you otherwise

£500–£1,000 per estimate. Or 10 hours of your life.

After 20 years estimating by hand, here's the maths I've done a thousand times.

Cost of one estimate

  • Hire a QS: £500–£1,000 per estimate
  • Do it yourself: 10 hours × £50/hr = £500 of your time

Why I built this

Built by a builder, for builders.

"I'm Alex. 20+ years building in London. I lost too many Sundays measuring drawings by hand and too many jobs to faster quotes. So we built Max — the tool I wish I'd had on day one."

Common questions

What builders ask before signing up.

What's the pre-launch offer?

Every UK builder who reserves a spot before launch in June 2026 gets £25 per estimate on their first 5 estimates. After that, standard pricing applies. You'll also be first in line for every new feature we ship.

What if my first estimate isn't good enough?

You don't pay. Simple. You only pay if the estimate is good enough to send to your client. We're confident enough in Max to put it in writing.

Is my data safe? Can I trust this with client drawings?

Yes. Your drawings and project data stay encrypted, are never shared with other builders, and are never used to train public AI models. We're UK-based and GDPR-compliant.

Can I edit the estimates before sending?

Of course. Max produces the heavy lifting — the estimate and the risk schedule. You review, tweak prices to your margin, and send. It's your estimate, with your branding.

Do I need to download anything?

No. Everything happens in WhatsApp. If you can send a photo to a mate, you can use 5 Minute Estimate. No app, no login, no CRM.

What kinds of jobs does it handle?

Extensions, refurbishments, loft conversions, new builds, kitchens, bathrooms, basements, commercial fit-outs. Anything where you're estimating from drawings and a site brief.

What happens after launch in June 2026?

Standard pricing kicks in at £50 per estimate. Builders who reserved before launch keep £25 per estimate on their first 5 estimates. This offer won't run again.

Pre-launch offer

Reserve before June 2026. Pay half on your first 5.

£25 per estimate on your first 5 estimates. After launch it's £50. No card required.
