Window & Door FAQs

How do I ensure my measurements are correct for quotation purposes?

To roughly measure windows and door dimensions, please follow the steps below:-

  • Decide which product you would like a quotation for.
  • Indicate whether you require Supply Only or Supply & Fit.
  • Measure window /door from edge to edge of the visible frame or opening (please see diagram below).
  • All window & door measurements should be given as width by height  eg. 1000w x 1500h
  • Roughly sketch the window/door showing the design & sizes required, as below
  • Indicate what part of the window/door should be open or fixed, as below
  • Indicate quantity of windows/doors required
  • Repeat for any other units required

The width, height and design will be sufficient for Carlson to prepare a quotation for either supply only or supply and fit.

However, if you decide to proceed we would advise you to ask the professional fitter to take accurate window & door measurements or if you are using our Carlson Supply & Fit Service we will arrange a convenient date for a site survey visit.
