The window calculator — price it yourself, or let the pros quote it
One pricing engine, two front doors. Homeowners build their windows in a visual configurator (or just describe the project) and get offers from verified local installers — free, no obligation, offers within 24 hours. Professionals use the same engine in a full PRO workspace to quote clients.

Everything a real quote depends on
Two quotes for the same opening can differ by 60% because of what's inside the frame. The configurator makes every one of those decisions explicit — so the price you see is priced on your actual window, not a vague €/m² band.
Exact dimensions
Width and height in millimetres, window by window — small windows and large spans are priced differently, and the calculator reflects it.
Opening type
Fixed, casement, tilt-and-turn (oscilobatiente), sliding — or a door. The hardware is one of the biggest price levers, and you can flip between types to compare.
Material & profile system
PVC or aluminium profile systems from leading brands, each with its real insulation values and price level.
Glazing
Double or triple glazing, low-E and solar-control coatings, acoustic laminated panes — the glass unit is where comfort (and a chunk of the price) lives.
Colour & finish
White, wood-effect laminations and coloured finishes. Colour typically adds 20–30% to a PVC window, so seeing it in the price beforehand avoids the classic quote surprise.
Accessories
Monoblock shutters (persianas), mosquito nets, window sills, handles and frame extensions — itemised through the catalog instead of buried in a lump sum.
How it works
From a blank opening to comparable offers — most requests take a few minutes to send.
Build it or describe it
Configure each window with exact specs and watch the price update — or describe the project to the AI assistant and attach photos. Approximate sizes are fine; binding measurements happen on site later.
Say where and when
Your postcode matches you with local companies (nothing is shown publicly). Choose turnkey installation or delivery only, and set your timeline — ASAP, 1–3 months or flexible.
We match 3–5 verified companies
Your request goes out securely to partner companies selected by ratings and proximity. No public listing, no cold-call marketplace.
Offers arrive within 24 hours
Companies email you their offers — every one priced on the same configuration, so comparing is finally like-for-like. Most clients save 10–20% by comparing.
For professionals
The PRO calculator
The consumer wizard above is the guided front end. Behind it sits the full professional calculator — the same pricing engine, opened up completely — that installers, dealers and manufacturers on Estimia use to quote their clients every day.
Full workspace, every parameter
The complete three-panel workspace: construction drawing, full parameter tree and live pricing side by side — nothing simplified away.
Your catalogs and price lists
Work with your own profile systems, markups and price lists — the calculator compiles your company configuration, not a generic one.
Glass price comparison
Compare glass-unit options across the catalog by spec and price before committing a quote to one.
From calculation to quote
Every calculation saves straight into an order: client-ready PDF quotes with construction diagrams frozen at quote time.
Built into a CRM
Orders, quotes, client approvals and a client portal — the calculator feeds the pipeline instead of a spreadsheet.
Widget for your website
Embed the quoting widget on your own site and turn visitors into configured, priced leads.
Why the number is honest
Estimia is an aggregator, not a seller — we don't manufacture or install windows, so the calculator has no reason to flatter the price up or down. It exists so that when the real offers arrive, you already know what fair looks like. Cross-check it against our real price list by size, then see what the grants and the IRPF deduction take off the total, and what your province's building code requires.
Frequently asked questions
Is the window calculator free?
Yes — free and with no obligation. You configure the windows or describe the project, see where you stand, and only share contact details at the final step so companies can send you offers. You can even submit anonymously, or create an account to track all your requests in one place.
Do I need exact measurements before I start?
No. If you have sizes, the configurator takes exact dimensions in millimetres and prices them instantly. If you don’t, take the "just describe it" path: tell the assistant what you need in a few words, attach a photo of the old window, and companies come back with options. The installer you choose always takes the final, binding measurements on site.
What exactly can I configure?
Material (PVC or aluminium), the profile system, the opening type — fixed, casement, tilt-and-turn, sliding or a door — exact sizes, glazing, colour, and accessories such as monoblock shutters, mosquito nets, sills and handles. The price updates as you build.
What happens after I submit my request?
Your configuration is sent securely to 3–5 partner companies in your area, matched by ratings and proximity to your postcode. They email you offers, typically within 24 hours, and you compare them side by side — most clients save 10–20% by comparing.
Can I choose delivery only, without installation?
Yes. At the final step you pick the job type: turnkey (installation plus removal of the old windows) or delivery only. You also set your timeline — as soon as possible, in 1–3 months, or flexible — so companies can price and prioritise accurately.
Does it cover doors and sliding systems too?
Yes. The same wizard handles windows, doors, sliding systems and catalog accessories, so you can price a whole renovation — not just a single opening — in one request.
What is the PRO calculator and how is it different?
It is the same pricing engine in a full professional workspace: every technical parameter exposed, your own catalogs and price lists, glass-unit price comparison, and every calculation saved straight into orders with client-ready PDF quotes. The consumer wizard is a guided front end; the PRO calculator is the tool installers and manufacturers quote with.
How do I get access to the PRO calculator?
Register for a professional account on the Estimia platform. Once your workspace is set up you get the full calculator, the CRM it feeds into, and a quoting widget you can embed on your own website.
