About pine-zone

Dedicated specialists in secondary glazing installation, committed to enhancing the comfort and efficiency of properties across the United Kingdom.

Our Approach to Glazing

We recognise that every property presents unique challenges and opportunities. Whether you own a Georgian townhouse in a conservation area or a modern apartment overlooking a busy street, our team approaches each project with the same attention to detail.

Secondary glazing has evolved considerably over the years. Modern systems are virtually invisible, highly effective, and can be tailored to complement any architectural style. Our role is to guide you through the options and deliver a solution that meets your specific needs.

Precision

Every measurement matters. We survey each window individually, accounting for irregularities that older properties often present. This ensures a perfect fit every time.

Transparency

We provide detailed quotations with no hidden costs. You'll know exactly what you're paying for before any work begins, and our pricing remains fixed throughout the project.

Expertise

Our installers bring years of experience working with diverse property types. From sash windows to casements, we understand the nuances that each style demands.

Aftercare

Our relationship doesn't end at installation. We offer ongoing maintenance services and support to ensure your secondary glazing continues to perform optimally.

Working with Listed Properties

A significant portion of our work involves properties with heritage designations. We understand the regulatory requirements and aesthetic sensitivities that these buildings demand.

Our heritage range uses slim aluminium profiles and high-clarity glass to minimise visual impact while delivering the thermal and acoustic benefits you need. Many of our systems have been approved for use in Grade I and Grade II listed buildings.
