Services
Windows Installation
We install UPVC, aluminium, and timber windows with enhanced security features and thermal efficiency. Our products reduce noise, condensation, and energy costs while maintaining aesthetic appeal. Available in casement, sash, and bespoke heritage designs to suit traditional and modern properties.
Conservatory Design
Creating custom conservatories with Victorian, Edwardian, and lean-to designs. We offer roof upgrades using polycarbonate, glass, or solid systems to improve usability and energy efficiency. All structures comply with building regulations and can be tailored to existing architectural styles.
Secondary Glazing
Internal glazing solutions that improve thermal insulation and soundproofing without replacing existing windows. Available in horizontal/vertical sliders, hinged units, and lift-out designs. Ideal for listed buildings and conservation areas requiring minimal structural changes.
Roof Upgrades
Modernising existing conservatory roofs with insulated polycarbonate, glass, or solid systems. Our upgrades enhance thermal performance, reduce solar heat gain, and transform conservatories into year-round living spaces. All installations include building control certification and energy efficiency guarantees.
Doors Replacement
Supplying and fitting front, stable, bi-folding, and commercial doors in UPVC, aluminium, and timber. Our security-enhanced composite doors feature multi-point locking systems. Heritage options maintain traditional aesthetics while incorporating modern insulation and safety standards.

Peter's firm have previously replaced all our windows, back and front doors, gutters, etc. Today they replaced porch door with new door and side panel. Perfect and as always very friendly, efficient service. Price as quoted, good communication throughout the whole process from quote through to completion. Brilliant, would highly recommend.

Report
We had all windows and doors replaced on our property earlier this year. Crittall Windows did a great job at a very competitive price. Peter provided excellent advice on styles and finishes to suit our cottage. The installation team were friendly, efficient and clean, and were more than happy to come back after installation to make a couple of small adjustments. I highly recommend this company and would definitely use them again.
