01

Choose the style before the price

Casement, flush sash, bay, bow, tilt-and-turn and aluminium windows each solve different design and practical needs. We begin by understanding the property and the result you want.

uPVC or aluminium

uPVC offers excellent versatility, familiar detailing and broad colour choice. Aluminium provides slim lines, strength and a crisp modern finish. We manufacture both in Bristol and can explain the differences in context.

From one window to the whole house

There is no requirement for the project to be a particular size. We can discuss a single problem opening, an extension, a staged replacement plan or a coordinated whole-house scheme.

From one window to the whole house

Planning and specification

What to consider when choosing replacement windows for a whole house or a single opening

A good quotation begins with the property and the way the opening will be used. We look at frame material, opening style, ventilation, glass specification, colour and sightlines. The best answer is not always the same for every room, so it is worth considering privacy, daylight, furniture positions and how often an opening will be used before settling on a specification.

Master Plastics can discuss casement, flush sash, tilt-and-turn, bay and bow window options. We manufacture made-to-measure products in Bristol and can provide supply only or professional installation across Bristol and nearby areas, depending on the project. Installed work is surveyed before manufacture; supply-only customers remain responsible for confirming their order sizes and fitting requirements.

From first enquiry to finished order

For a whole-house scheme, photograph every elevation and note which rooms need privacy, escape openings or regular ventilation. This helps keep external sightlines consistent without forcing every window to use the same internal arrangement.

Window prices change with size, opening pattern, glass, colour and access. Comparing quotations only works when those elements—and the installation and making-good included—are genuinely alike.

Choosing the arrangement

Design the elevation and each room together

The external appearance benefits from consistent head heights, mullion positions, colours and glazing bars. Inside, however, bedrooms, bathrooms, kitchens and living rooms can need different combinations of ventilation, privacy and opening access.

  • Casement windows for flexible fixed, top-hung and side-hung layouts
  • Flush sash or sash-horn detailing for more traditional proportions
  • Tilt-and-turn operation where inward access and ventilation are useful
  • uPVC or aluminium selected around sightlines, scale, style and budget

We record every opening separately so a coordinated exterior does not mean compromising the way each room works.

Windows chosen for the building

At Newdaw Apartments on Staple Hill High Street, white uPVC windows were arranged around repeated arched heads and matching dormers. The project shows how a modern system can respect a strong elevation rather than flatten its character.

Good to know

Questions about replacement windows

Can you replace a single window?

Yes. We can discuss one failed or difficult window, a new opening, a staged renovation or a complete property. The product and installation requirements are considered for the actual opening rather than a minimum package.

Should I choose uPVC or aluminium?

uPVC is a versatile and cost-effective choice with traditional and contemporary styles. Aluminium is often selected for slimmer sightlines, larger panes and a crisp architectural finish. We can compare the practical differences for your property.

Is double or triple glazing best?

That depends on the frame system, glass area, orientation, noise and the performance required. Triple glazing is not automatically the best answer for every opening, so glass and frame should be specified together.
