UPVC Windows
Our high-performance UPVC windows enhance thermal efficiency and security while reducing noise pollution. Featuring 70mm profiles, A-Rated glazing, and customisable designs including bay, casement, and box-sash styles, they suit both heritage and modern properties. Backed by a 10-year guarantee, installations use reinforced frames and advanced sealing technology to ensure durability and energy savings.
Composite Doors
Security-focused composite doors combine multi-point locking systems with reinforced profiles for enhanced protection. Available in Rockdoor and Distinction ranges, options include custom colours, decorative glass, and high-security ironmongery. The thermally efficient designs prevent warping, fading, or discolouration while maintaining aesthetic appeal across property types.
Conservatories
Tailored conservatory solutions include Edwardian, Victorian, and bespoke designs with optional tiled or glass roofs. Our installations feature thermally efficient frames, decorative glass options, and integrated climate control solutions. Designed to add functional living space and property value, all projects include planning guidance and structural compliance certifications.
Roofline Products
Durable PVC fascias, soffits, and guttering replace traditional timber with maintenance-free alternatives. Resistant to rot, pests, and weather damage, these components improve ventilation while preventing water ingress. Available in multiple colours, installations ensure long-term structural protection and enhanced kerb appeal through seamless, weatherproof fitting.
Porches
Custom UPVC porches create weather-protected entryways with options for tiled, glass, or Tapco roofs. Designs incorporate decorative glazing, colour-matched profiles, and brickwork or render finishes to complement existing architecture. Fully installed solutions include structural support, weatherproofing, and compliance with building regulations for year-round usability.

Report
Really pleased with new front door fitted recently by Mark, who did a really neat job. Tracy was really helpful to arrange the work and help us choose the door. As Rainhill UPVC had done a great job to replace our roofline a couple of years ago, I had no hesitation contacting them for this recent work. A friendly, family-run local firm I would thoroughly recommend.

A five star service from initial quote to the fitting of my new front door. Tracy was friendly and knowledgeable and kept me updated constantly. I am delighted with my new front door and have no hesitation in recommending this outstanding company.

Report
Had a new door with combination frame fitted in January 2020, so when we decided on new replacement glass we went back to Rainhill UPVC Windows for a quote, as i wanted bevels in the glass to match the door,. In the end had full replacement glass with frames and I'm glad we did.. has completely lifted the look of the house,. I would highly recommend this company for the workmanship and the staff, lovely people. Also thanks to Tracy for her patience & super quick correspondence.
