Windows and doors in Leeds
Calder Windows in Leeds
We're Calder Windows, a family-run specialist in windows and doors in Leeds and the surrounding areas. Based on 71 High Street in Normanton, we’ve been fitting windows, doors, conservatories and extensions across Leeds and West Yorkshire for over 30 years.
Whether you’re in central Leeds, Headingley, Chapel Allerton, Moortown, Roundhay, Alwoodley, Horsforth, Pudsey, Garforth, Morley or any of the outer areas, we’ll come out and quote.
Leeds is a city of varied property stock
One of the things we like about Leeds is that no two streets feel the same. The back-to-back terraces of Harehills are a world away from the large detached homes of Alwoodley. The Victorian stone villas of Headingley don’t ask for the same window solution as a new-build in Garforth. The 1930s bay-front semis of Moortown need different glazing decisions than a converted mill in Kirkstall.
That variety is the part of Leeds we know best. Over 30 years of work across the city and its suburbs means we’ve fitted almost every property type the city has to offer.

Victorian and Edwardian terraces
Found across Headingley, Harehills, Armley, Burley, Hyde Park, Woodhouse, and central Leeds. Sliding sash windows and flush sash casements are almost always the right specification for these properties. The street scene depends on the front elevation, and we’ll talk through the options in a way that respects that.

1930s semis and suburban housing
Moortown, Roundhay, Alwoodley, Crossgates, Farnley, Morley, Horsforth, Bramley, and much of outer Leeds. Casement and bay window replacements are the most common work. Anthracite grey and Irish oak finishes are the most-requested colours.

New-build estates and modern apartments
The growing development areas around east Leeds, the city centre apartments, and the modern housing estates. Aluminium windows and bifold doors on contemporary extensions are the most common requests.

Converted mills and industrial properties
Kirkstall, Holbeck, Hunslet, and central Leeds have a strong stock of converted mills and warehouse apartments. Heritage-style aluminium doors and large glazed openings are the characteristic specifications here.
What we fit in Leeds
Everything we fit across the rest of West Yorkshire, from a single replacement window to a full rear extension.
Windows
Casement, flush sash, Omnia, sliding sash, tilt and turn, bay, aluminium, and triple glazed upgrades.
Doors
Composite front doors, Rockdoor, uPVC doors, French doors, sliding patio doors, bifolds, and heritage aluminium.
Conservatories, orangeries, and extensions
Traditional conservatories, contemporary and flat-roof orangeries, warm roof upgrades, replacement conservatory roofs, and full single-storey extensions.
Conservatories in Leeds specifically
Leeds has a huge stock of conservatories from the late 1990s and early 2000s that are now cold in winter and unusable in summer. Warm roof conversions are one of our most-requested jobs in the city, and they transform the space in ways homeowners don’t expect until they see them.
If you’ve got a tired conservatory in Leeds that’s become a dumping room, it’s almost certainly cheaper to replace the roof than to replace the whole structure.
Home extensions in Leeds
Single-storey rear extensions are the single most-requested structural work we do across Leeds. Most qualify under permitted development, though we always check the specific property. Kitchen extensions with bifold doors are the commonest brief, and we handle the full design, planning, and build.

Why Leeds homeowners pick Calder
We know Leeds housing stock
30 years of work means we’ve fitted almost every type of Leeds property. Period back-to-backs in Harehills, Victorian villas in Headingley, 1930s semis in Moortown, new-builds in Garforth, converted mills in Kirkstall. The variety is the job.

Normanton is 25 minutes from central Leeds by road. We’re close enough to get to you quickly and back for any aftercare, but not one of the Leeds-centric window companies that push volume over craft.
