Home Extensions
Allerton Windows designs and constructs single-storey and kitchen extensions tailored to individual needs. Our projects include bifold doors, roof lanterns, and seamless integration with existing properties. We manage every stage from planning permission to final construction, ensuring compliance and quality. Our team delivers functional, light-filled spaces that enhance property value and family living.
Conservatories
We build Edwardian, Victorian, and lean-to conservatories with customisable options for glazing, roof types, and finishes. Our structures feature thermally efficient glass and durable uPVC or aluminium frames. The team ensures precise installation and offers retrofit solutions like solid roof replacements for improved insulation and modern aesthetics.
Windows
Our made-to-measure uPVC and aluminium windows include casement, sash, and heritage styles. Features include A++ energy ratings, multi-locking systems, and lead-free construction. We provide noise reduction, security, and low-maintenance solutions, with options for Georgian bars and custom colours to suit period and modern properties.
Doors
Allerton Windows offers secure uPVC, composite, and bifolding doors with thermal efficiency and modern designs. Products include Rockdoor-certified composite doors, aluminium sliding systems, and bespoke options with glass panels. Our installations ensure draught-proof seals, durability, and enhanced kerb appeal with 10-year guarantees.
Conservatory Roof Replacement
We retrofit existing conservatories with Celsius solid roofs for improved insulation and aesthetics. The system includes insulated panels, triple-glazed units, and seamless integration with original structures. This upgrade transforms outdated conservatories into year-round usable spaces while maintaining compliance with building regulations.

Very impressed with the whole team from surveying to fitting. All done efficiently, quickly and without mess. Far more professional and cost effective than a so national windows firm who blow there own trumpets with TV adverts.

Composite door supplied and fitted. Arrived with a scratch, rather than be properly repaired it was touched up and we had to ask for a partial refund. Less than 6 months later, we have paint flaking off around the trim where the door was improperly painted without the trim being removed and painted separately. Been trying to get it sorted for months. They sent a guy out, had the wrong colour paint. That was January and we are now in to March. Every time I speak to somebody in their office it feels like they are doing you a favour and that your call is a burden to them. Would not use again.

Why is so hard to supply a quote? Three times I phoned for a quote and three times I was told someone would phone me back but no one has. Thanks for that.

Had two bedroom and a bathroom window fitted recently. Managed to get a quote relatively quickly and they were fitted about 5-6 weeks later. The lads did a brilliant job and were dead sound, made sure no mess was left afterwards. Glad we went local as the price was reasonable compared to other companies (looking at you Safestyle )

We have recently had a replacement Guardian Solid Roof System installed on our existing conservatory by Allerton Windows. We are extremely happy with the finished job and could recommend the company. Many thanks to Tony and the team from Allerton Windows.
