Conservatory Roof Replacement
We retrofit Celsius solid roofs onto existing conservatories, enhancing thermal efficiency and durability. Our solutions reduce energy costs while maintaining aesthetic appeal. The process involves removing old glazing and installing insulated panels with a 10-year guarantee against fading or warping. This service transforms outdated conservatories into year-round usable spaces.
Home Extensions
From single-storey rear extensions to full orangery conversions, we create bespoke living spaces tailored to architectural styles. Projects include structural alterations, electrical rewires, and integration of bi-fold doors. Our team manages planning permission guidance and ensures compliance with building regulations across Liverpool and the North West.
Windows
Our made-to-measure uPVC and aluminium windows feature fusion-welded joints and A++ energy ratings. Security systems include multi-locking mechanisms and impact-resistant glazing. Installation includes draught-proofing seals and options for heritage designs compliant with conservation area requirements.
Doors
We supply and install composite, uPVC, and bi-fold doors with thermal efficiency up to 25% higher than industry standards. Options include Rockdoor's police-approved security systems and Liniar's low-maintenance profiles. All doors feature dual seals against weather ingress and come with 10-year performance guarantees.
Conservatories
Available in Edwardian, Victorian, and lean-to styles, our conservatories use Liniar profiles and Celsius glass technology. Features include ModLok structural systems for enhanced stability and Stratus aluminium lantern roofs that maximise natural light.
