Spring, opener and warranty records

Garage door service software that remembers every spring size

DoorSpec Book is garage door service software: a searchable record, for small repair and install companies, of every door they have worked on, with its torsion spring sizes, opener model, install dates and warranty end dates.

No card for the first 14 days. Solo is $19 a month after that.

Inside a door record

Spring specs as real fields, not a note nobody can search

Garage door spring size records

Wire size, inside diameter, length, wind, quantity and cycle rating on every spring set, as real fields, with the install date. Replace a set and the old one moves to the door's history.

Double bay · 14 Birch Ln

A door record for every bay

Door type, width and height, weight, maker, model, panel style and track radius, one record per door, so a three-door house or a twenty-door warehouse stays straight.

Opener on file

Brand, model, serial, drive type, horsepower, battery backup and remotes, with its own part and labor warranty.

Warranty tracking for customers

Door, part and your own labor warranty dates on everything. Set your default lengths once and they fill in from the install date. The Warranties page lists what's covered and what ends in the next 90 days.

Service history per door

Each visit logged against the door it was on: work type, parts used, a photo link, who did it, and whether it was warranty work.

Truck sheet

One printed page per property: address, gate code, every door, its springs and opener.

A spring call, timed

A broken spring is a one-trip job when the size is already written down

Below, one customer's call handled twice: from memory and old invoices on the left, from her door's record on the right.

  1. 7:40

    From memory: A customer calls: the spring on her double door snapped this morning.

    From the door book: Same call.

  2. 7:42

    From memory: Was it 0.243 or 0.250 wire? 2 inch or 1¾ inside diameter? The invoice from 2024 is in a box somewhere.

    From the door book: Office types "Birch" and reads it off the screen: 2 × 0.243 × 2" × 31", pair, 10,000 cycles, installed by us Mar 2024.

  3. 7:45

    From memory: The tech loads three sizes "to be safe" and a spare set of cones.

    From the door book: The tech loads one matched pair.

  4. 9:10

    From memory: On site, the guess was wrong. Back to the shop, or the supply house.

    From the door book: Springs on, door balanced, visit logged from the phone.

  5. Later

    From memory: She asks if it's still under your labor warranty. Nobody knows.

    From the door book: Your labor warranty ended Mar 2025, but the springs' part warranty runs to Mar 2027: parts covered, labor billed. A straight answer on the first call.

What it costs

Three plans, sorted by door count

All three keep springs, openers, warranties, service visits and truck sheets, and all three import your old customer list.

Logins and limits

Nobody outside the owner can delete a customer

Each login gets a role. What each role can do with the records:

OwnerOfficeTechProperty manager
Look up any door, springs and openerYesYesYesTheir buildings
Add or correct specs, springs, openersYesYesYesNo
Log a service visitYesYesYesNo
See gate and keypad codesYesYesYesNever
Delete customers and propertiesYesNoNoNo

Office and tech logins are on Crew and Fleet; property manager logins on Fleet. A tech sees only the service visits they logged.

Questions from door shops

Before you put your doors on file

Is this a garage door spring size chart or calculator?
No. Charts and calculators work out what spring a door should have from its weight and height. DoorSpec Book records what's actually on each customer's door, measured by your tech, so the next call starts from the real size instead of a recalculation.
Is this a garage door CRM?
Partly. Keep scheduling and invoicing in Jobber, Housecall Pro, QuickBooks or the paper calendar on the wall; DoorSpec Book holds what those tools don't: the door itself, its springs and opener, the warranty dates and every visit.
Why not use the equipment notes in our field service app?
Most field service apps store equipment as a name, a serial number and a free-text note. Nobody types wire size, inside diameter, length and wind the same way twice in a note, so it can't be searched or trusted. Here they're separate fields on every spring set.
What should a tech measure on a torsion spring?
Four things: wire size (measure 10 or 20 coils and divide), inside diameter (usually 1¾, 2 or 2¼ inches), length of the coils unwound, and wind (left or right, by which way the end points). Add the cycle rating if the label is readable. Those are the fields on every spring set.
Does it handle commercial doors?
Yes. A door can be sectional, roll-up, rolling steel, carriage, one-piece or commercial sectional, with its own size, weight and track. A warehouse with twenty dock doors is one property with twenty door records.
Can a property manager see their doors?
Gate and keypad codes never show for them; everything else about their own buildings does. On the Fleet plan, an HOA board member or a facilities person gets a login tied to the addresses you pick, can look but not change anything, and can download a spreadsheet of the doors and visits.
