Trusted internal-access glazing support for public-sector estates

We provide specialist window installations, trusted window repairs and double glazing services for public-sector properties, social housing providers and challenging access sites, delivered using our unique engineered systems to eliminate the need for scaffolding.

Reliable, Specialist Support for Complex Projects

Whether working on high-rise blocks, secure government and diplomatic buildings, police facilities, schools or properties beside rivers and railways, our certified teams use Glazesafe’s patented systems, Stronghold and Sashmate, to complete repairs and installations safely from inside the building, without the disruption, risk or cost of external access equipment.

Trusted by Councils Across the UK

Certified internal-access glazing teams delivering projects for councils, housing providers, ALMOs and secure public-sector estates.

Faster, Safer Glazing for Hard-to-Reach Areas

Stronghold and Sashmate deploy internally in minutes, reducing time at height and avoiding delays caused by scaffold mobilisation.

Removing Risk and Disruption

Complete high-rise and restricted-access glazing internally, avoiding resident decants, façade obstruction and prolonged scaffold exposure.

Cost-Saving Internal Access

By eliminating scaffold and MEWP hire, our approach typically removes thousands of pounds of access cost per project — allowing more budget to be directed into actual repairs.

Specialist window installations – at height

Our teams deliver certified internal-access window, glazing and balcony repairs and replacements across social housing, council estates and secure properties. All works are completed from within the building using our engineered Stronghold and Sashmate systems—reducing work-at-height risk, removing the need for external access and maintaining resident safety and site security.

This approach enables us to support high-rise blocks, public-sector facilities and complex locations where scaffolding would normally be required. Using our patented systems, our trained installers resolve glazing issues efficiently and securely, while maintaining full compliance with relevant safety regulations and industry standards.

Emergency works and planned glazing programmes

Glazesafe delivers both emergency, safety-critical glazing works and planned capital or maintenance programmes. Our internally deployed Stronghold and Sashmate systems allow rapid mobilisation without scaffold lead times, enabling urgent works at height to proceed safely.

For planned programmes, this approach provides programme certainty, minimised resident disruption and significant savings compared to traditional external access costs.

Window and door installations

We support public-sector projects, planned maintenance programmes and sites where external access is disruptive, impractical or costly. Our internal-access methods enable safe window and door replacements in schools, police facilities, secure residential units and multi-storey housing.

All works use Stronghold and Sashmate — patented, tested systems engineered for complex environments — delivering a practical, compliant, scaffold-free solution for councils, housing providers and principal contractors.

Solutions for complex access sites

Where scaffolding or traditional external access is impractical, high-risk or costly, Glazesafe uses engineered internal-access systems to enable safe working at height. Our trained teams carry out glazing repairs, replacements and installations in complex environments, including high-rise blocks, riverfront properties, railway-side estates and secure facilities, helping clients meet safety, compliance, security and budget requirements.

Over 20 years, we’ve delivered bespoke, scaffold-free solutions trusted by councils and social housing providers. Our experience in the glazing and construction industry, along with our ‘out the box’ methodology have made us a highly valuable and unique partner.
