Premium aluminium glazing • Local survey & installation
Windows in the Lakes specialises exclusively in aluminium windows and doors for homes across Cumbria and the Lake District. We work with homeowners upgrading tired frames, extending their homes, or replacing glazing in character properties where appearance and performance matter.
Every aluminium window installation is managed from initial advice through to final sign-off. That means accurate surveying, carefully specified systems and experienced installation teams who understand local property styles, planning sensitivities and long-term performance requirements.
This is not supply-only glazing. It is a fully managed service designed to deliver exactly what you approved.
