Upgrading your windows and doors is one of the most effective ways to improve comfort, increase energy efficiency, and modernise the look of your home.
At Crown Windows, we know the process can feel like a big task, so here’s a clear breakdown of what to expect.

1. Initial Consultation
Your project starts with a personal consultation. Our experienced team will assess your home, listen to what you’re looking for, and advise on suitable options. Budget, material preferences, and styling are all considered.
You’ll also receive a free 3D design plan to help you visualise the end result. Whether you’re replacing upvc windows, looking at composite doors, or planning a full home improvement project, we’re here to guide you.

2. Accurate Measurements and Product Selection
We’ll visit your property to take detailed measurements. This ensures your new windows and doors are made to fit precisely, avoiding issues later.
You can then choose from our wide range of highest-quality products:
- uPVC windows
- Composite, patio or bifold doors
- French doors and Flush sash windows
- A variety of colours, finishes, and hardware options
We also offer optional fittings such as cat flaps, decorative glazing, and hardware upgrades.
3. Custom Manufacturing
Once your choices are confirmed, your products are manufactured to order. This made-to-measure approach delivers a clean fit and reliable performance. All window replacements are created using the highest quality materials to suit a range of styles and property types.
4. Professional Installation
On installation day, our skilled technicians and dedicated team work efficiently and respectfully:
- Removal: Old windows and doors are carefully taken out
- Preparation: Openings are cleaned and prepped
- Fitting: New units are installed, sealed, and tested
All work is completed by FENSA-registered installers with decades of experience, ensuring long-term performance and peace of mind.
