Window & Door Survey Services, South East England

We offer the service of a full site survey. This involves an accurate site measure with the use of a laser, along with the full confirmation of all applicable building regulations to all the doors and windows included in your project.

This allows us to ensure and highlight details such as applying safety and barrier glass in the correct locations. Doing so makes certain a means of escape and background ventilation is included where required.

From this laser site survey, we can place your order directly into the factory for manufacture. This service can be offered on both supply only and supply/installation projects, catering to all sectors
