Confirm installation dimensions before ordering
Wall thickness, opening size, handing and finished floor level determine the choice. Measuring before ordering prevents an attractive product from arriving in the wrong dimensions.
Plan the window and its connection to the building together
Window fixings, sealing and connections to the building must be considered together. Technical requirements and responsibilities must be defined for the specific component.
Assess special components separately
Fire, smoke and acoustic doors have specific requirements. Changes to façades or listed elements also require a separate review before work starts.
Well prepared
What we clarify before you commission the work.
Tell us the quantity, dimensions and desired elements. For windows or bespoke joinery, technical conditions, required authorisations and the specialist contractor are agreed beforehand.
Work & quotation
What affects the work your project needs.
Component type, dimensions, fittings, substrate, removal of old elements and connection work affect the quotation. Special requirements are described separately.
Project insights
Take a look at a related example.

When are interior doors installed?
The finished floor level should be established. The actual sequence depends on the frame type, flooring system and other interior work.
Is bespoke timber work possible?
Requested adjustments or fitted elements are assessed for feasibility and specialist execution. An enquiry does not itself confirm that a particular bespoke item can be supplied.
