For window, door and shutter companies of 2–20 people — installers and manufacturers, across Europe. The conversations and figures below are illustrations, not client stories.
Window & door companies: win the quotes you are already sending
Every house needs windows and doors, and every 20–30 years they are replaced. Your enquiries are valuable — but they arrive by phone, email, WhatsApp and website, and quotes go out with nobody calling back. We put every enquiry and quote in HubSpot and add AI agents that answer at night, book measurements and tell you who to call.
Sound familiar?
- Enquiries arrive in four places — phone, email, WhatsApp and the website form
- Quotes are sent, and nobody follows up; customers quietly buy from a competitor
- Installers are called on site: “when will you come to measure?”
- Evening and weekend enquiries wait until Monday
- Past customers are never asked about shutters, a front door or the rest of the house
The AI agents for a window & door company
Start with one agent, then add the next. Each agent works inside your own HubSpot account.
24/7 sales agent on your website
Answers visitors’ questions day and night — profiles, glazing, colours, lead times, warranty — and turns the conversation into a measurement request in HubSpot. It never invents a price.
Most enquiries come in the evening
Quote follow-up agent
Three days after a quote, the customer gets a polite reminder. You get a list of quotes that were opened but not answered.
Quotes that go quiet
Weekly AI list
Every Monday, AI reads your CRM and tells you who to call this week — and why.
Owners with no time to check
Repeat-sale agent
Finds past customers due for doors, shutters or the rest of the house, and drafts a personal message.
Growing from your own customers
The 24/7 sales agent, in action
What you get: A new contact and a deal in “Measurement requested” appear in HubSpot, with all the details, and the office has a task for the morning. The customer got answers on a Sunday evening — and didn’t keep searching.
Monday morning: the AI list
The owner opens HubSpot on the phone and sees who to contact this week — and why.
What runs automatically in HubSpot
- The AI agent introduces itself as an AI assistant, as the EU AI Act requires, and hands over to a person whenever needed
- Every enquiry — website, email, WhatsApp, phone — becomes a contact and a deal
- Pipeline: enquiry → measurement → quote → won → installed
- Instant reply to every enquiry, also at night and at weekends
- Quote reminders to the customer after 3 and 10 days
- A task for the installer and a confirmation to the customer before each measurement
- After installation: a thank-you and a review request
What you prepare
About two hours of your time. GrowFlow does the setup, testing and monthly improvement.
- 25 frequent questions with your answers: profiles, glazing, colours, lead times, warranty, payment terms
- The rule: the agent never quotes a price — it books a measurement
- Which towns and regions you cover
- Who receives handed-over conversations, and how fast they reply
Example calculation
Example figures to show how to think about value — not a promise of results. HubSpot prices change; the AI chat agent needs a HubSpot Professional plan, and we confirm costs with you before anything is switched on.
Which plan fits
Recommended: AI customer service setup (€2,350 one-time) + the Growth plan, for the weekly AI list, quote follow-ups and monthly improvements. See also our example scenario of a 12-person installer in Belgium.
