We deliver excellence right from the start.
We start with a visit to your home to measure up and discuss your requirements and options. We examine the style of the property and existing windows to discuss the most suitable replacement; either like-for-like or something new. We take into consideration the proportions, thickness of the frame, type of glass, colours, door styles, etc. We can also discuss phasing of the project and the different cost options to best suit your budget.
We will provide a detailed proposal with each window and door drawn to scale and a professional quotation with price breakdowns, giving total clarity and transparency.
If you’re considering a change of design , taking on a new build or renovation project, or if you have architects plans that don’t quite have the wow factor that you were hoping for, our in-house studio can provide you with full-colour, photographic-quality, 3D visuals to help you visualise and explore the various options. This service is free of charge. You can find out more about this service here.
