Window Estimation Software

Professional window estimation software for contractors, fabricators, and installation businesses. Labour, materials, overheads, and markup — all automated.

Estimate With Confidence, Win With Margin

Stop losing money on under-priced quotes. Doorwin builds every estimate from your real cost base.

1

Labour Rate Engine

Set daily rates for surveyors, fabricators, fitters, and labourers. Doorwin calculates hours needed per window based on size, complexity, and access — then applies your rate plus overhead allocation.

2

Material Cost Database

Live cost prices for profile systems, glass, hardware, seals, trims, and fixings. Update a single line and every open estimate recalculates. No more quoting at last year's prices.

3

Job Complexity Factors

Add factors for scaffold access, 1st-floor fitting, listed-building restrictions, narrow access, and fragile substrate. Each factor carries its own time and cost uplift that you can edit per job.

4

Markup & Win-Rate Analysis

Set minimum acceptable margin per window type. The built-in dashboard tracks what you bid, what you win, and what margin you actually deliver — so you stop quoting jobs that lose money.

Frequently Asked Questions

How is this different from a quoting tool?
Quotes are the output; estimates are the inputs. Doorwin estimates cost price accurately (materials + labour + overhead), then applies your margin to produce a sell price. Most small contractors under-estimate labour by 20-40% — estimation software prevents that.
Does it support multiple estimators on the same job?
Yes. A surveyor collects measurements, an estimator builds cost, and a salesperson applies margin and presents the quote. All three work in the same job file with role-based permissions and change tracking.
Can I import my existing supplier price lists?
Yes. Upload CSV price lists from Rehau, Veka, Reynaers, Schüco, glass suppliers, and hardware factors. Doorwin imports SKUs, unit prices, and volume discounts — then uses them for every estimate.
Is there an audit trail for bids and revisions?
Every estimate version is versioned with timestamp, user, and change notes. Required for quality management and very useful when a client disputes the specification months later.
