Koll for renovation and construction companies

Turn quote requests into real conversations.

A valuation visit, quote, schedule change, or site matter shouldn't get lost behind an unfamiliar number. Koll tells the customer exactly what the call is about. Every contact is based on the customer's own request or consent — and the reason is visible before they answer.

What it costs you right now

01

Quote requests stall

A customer requests a quote but won't answer an unknown number, so the valuation visit never gets scheduled.

02

Site communication breaks down

Schedule, delivery, and extra-work matters need a fast connection. A missed call costs work hours.

03

The industry suffers from scam calls

The reputation of cold calls makes even an honest company's call look suspicious.

Here's how Koll solves it on-site and in sales

The business is verified, and every call states the company name and the reason for the contact.

  • A verified company identity sets honest businesses apart
  • Reason for the call: valuation visit, quote, delivery, or site matter
  • Works from the mobile phones of installers and site managers
  • The company controls who can call under its name

Examples of call reasons

  • Quote request

    Reno Co – calling about your quote request

  • Valuation visit

    Reno Co – scheduling a valuation visit

  • Delivery

    Reno Co – your delivery arrives tomorrow

  • Site matter

    Reno Co – a matter concerning the site

What changes

More quote conversations completed

Fewer wasted visits and call attempts

Clearer communication during the project

A more credible company image

Before and after

Here's how a typical day goes today

  1. A quote request comes in online or through word of mouth.
  2. The site manager calls from the job site – an unknown number.
  3. The customer doesn't answer, fearing a sales call.
  4. The valuation visit never gets scheduled, and the quote stalls.
  5. During the project, delivery and schedule calls go unanswered.

Here's how it goes with Koll

  1. The company name appears on every call.
  2. The reason for the call distinguishes the topic: quote, valuation visit, or site matter.
  3. The customer recognizes an honest business among the scammers.
  4. The valuation visit is scheduled on the first call.
  5. Site communication flows without wasted call attempts.

Where Koll helps in practice

Responding to quote requests

A fast, recognizable callback sets you apart from slower competitors.

Scheduling a valuation visit

Scheduling succeeds because the customer knows what it's about.

Approving extra work

Extra work needs an immediate customer decision – a missed call stalls the site.

Deliveries and logistics

Material delivery times are confirmed with a single call.

Schedule changes

When weather or deliveries shift, the customer stays reliably reachable.

Warranty and follow-up work

Follow-up and warranty visits run smoothly without endless message threads.

Koll is not a cost line – see what it returns

Leads, advertising and sales time are already paid for. Koll improves the one moment that decides whether they pay off – and it pays for itself with just a few extra deals. Adjust the numbers to match your own operation; everything is calculated in your browser and nothing is stored.

Privacy and control

Koll is built for the European regulatory environment. Your company decides who may call in its name and what the recipient sees.

  • No call recordings
  • Only verified users call under the company's name

Principles of ethical calling

Wanted contact isn't a marketing promise. It's the rule Koll is built on.

Cold calling breaks trust in both directions. Koll is built so the recipient always knows who is calling and why — and decides for themselves how to respond.

  • We don't call anonymously

    The company and the caller are verified. Recipients see a real company and a real person, not a random number.

  • We don't call without a reason

    Every contact carries a reason that is visible before the call is answered. No reason, no call.

  • The recipient decides

    Customers can answer, move the contact to a better moment or decline — without having to pick up the phone.

  • We don't listen or record

    Call content is never recorded or analysed. The service is delivered in the EU and each company manages its own users and data.

Frequently asked questions

Does this work from installers' own phones?
Yes. Users are linked to the company's verified identity, so the call appears under the company's name.
Can the reason for the call be customized?
Yes. The company manages its own templates, users can also write the reason themselves, and continuous reporting shows which reasons work best.
Does the customer need an app?
No.
What do we need to provide for WhatsApp messaging?
Your own Meta Business Portfolio and WhatsApp Business Account, a Meta-verified number (existing or separate), an approved brand profile with company name, logo and website, and authorisation for Koll via Meta's Embedded Signup. Messages are delivered as Koll SmartCards and are included in your calling team's fixed-price package. Recipients need a valid opt-in. Your current WhatsApp Business app on the phone can keep running (Coexistence).
Can an installer use their own phone?
Yes. The number is linked to the company identity and can be unlinked anytime.
Does this help with the industry's scam-call reputation?
A verified company identity sets you apart from anonymous cold calls.
Does this work with property management customers too?
Yes – property managers and board members are reached the same way.
