What your project can include
Sliding and patio doors
Compare opening widths, panel arrangements and the space available beside the opening. Threshold height, drainage and everyday access matter just as much as the frame colour.
Replacement windows
Discuss ventilation, privacy, glazing options and the condition of the surrounding wall. An accurate survey helps establish whether the existing opening can be reused and what making good is needed.
Entrance doors and glazing
A glazed entrance or sidelight can brighten a hallway. Plan hardware, locking arrangements and the relationship between the frame, wall and floor before ordering.


Before the site discussion
A little preparation helps
- Count the openings and take clear photos from inside and outside.
- Note sticking frames, draughts, water ingress or damaged finishes.
- Decide which openings need ventilation and which need easy outdoor access.
What affects the quote?
Opening dimensions, frame systems, glazing, hardware and removal of existing frames affect the quotation. Coastal exposure should be discussed when choosing finishes and fixings. Ask whether plaster repairs, painting, disposal and final sealing are included.
Discuss the scope, availability and pricing during the site visit, then review each contractor’s quotation independently.

Useful to know
Aluminium Windows & Doors questions
Can windows be replaced in the existing openings?
Often, but the installer needs to check the wall condition, dimensions and frame details. Any damaged plaster or changes to the opening should be included in the scope.
Are all aluminium systems suitable for coastal homes?
Product and finish choices vary. Explain how exposed the property is and ask the supplier about appropriate finishes, hardware and maintenance for that setting.
Who handles repairs around the new frames?
Confirm this before accepting a quote. Window installation, plaster repairs and repainting may be separate items, and larger opening changes may need building input.
