Field Software for Install Teams

Installers live on sites, in vans, and on phones. Doorwin is built for that reality — not for a desk.

1

Digital Survey & Measurement

Replace the pen-and-clipboard survey. Photograph every window opening, record measurements directly on the image, capture context (internal/external, level, brick opening vs finished opening), and sync to the office instantly. No re-transcription errors.

2

Job Schedule & Route Planning

Calendar view shows tomorrow's installs, their addresses, expected durations, and route order. One-tap navigation opens the address in Google Maps or Waze. Days are planned automatically based on location clustering — reducing unproductive travel time.

3

On-Site Install Checklist

Every install runs against a configurable checklist — level/plumb/square, trickle vent operation, restrictor function, glass in good condition, silicone applied, debris cleaned. Installer signs off each item; client signs off completion. Dispute-proof documentation for warranty claims.

4

Photo-Anchored Defect Reporting

Any issue on site — damaged profile, wrong glass spec, misaligned opening — photographed and tagged to the job. Office sees it immediately, can dispatch replacement or make-good before the team leaves the site. Cuts return-trip visits by 40-60%.

Frequently Asked Questions

Does it work in vans with poor signal?
Yes. Fully offline — surveys, measurements, photos, and completion sign-offs all work without internet. Data syncs automatically when the team is back in signal. Tested across rural install teams in the Highlands, the Outback, and rural French Brittany with no signal loss issues.
Can it work for multi-team installation companies?
Yes. Each installer has their own account with role-based access. Office sees the aggregate view — who's on which job, when expected back, what was installed today. Sub-contracted installers can be granted access per job rather than permanent accounts.
How does it handle FENSA / CERTASS certification admin?
Post-install, every job auto-generates the data required for FENSA or CERTASS notification — installer details, product data (U-values, WER), install address, install date. Exports in the format the notifier accepts, cutting certificate paperwork from 15 min per job to 2 min.
Is it useful for small (1-3 person) installer businesses?
Especially for small teams. A single installer running their business on WhatsApp, paper notes, and Excel has the most to gain from one integrated app replacing all three. Setup for a small team takes about 2 hours; break-even on time saved usually hits within the first month.
