Looking to improve security, insulation, or just refresh your home’s entrance? Our range of double glazed doors includes something for every space. Built with strong, weather-resistant materials and advanced locking systems, they offer both peace of mind and great looks.

Choose from composite front doors, aluminium bi-folds, and sliding patio doors – or go with classic uPVC French and patio doors. All styles are customisable and designed to work just as well in traditional homes as they do in more modern settings.

At P&M, we believe great double glazing is more than just a home upgrade — it’s a long-term investment in comfort, efficiency, and style. That’s why we only install top-quality products that are built to last, helping homeowners across Harpenden get the best from their windows and doors for years to come.

We use tough, low-maintenance materials like uPVC and aluminium, which won’t warp, rot, or rust over time. Just an occasional clean is all they need to stay looking great. With a lifespan of up to 30 years, our double glazed products are made for long-term performance and peace of mind.
