Aluminium Casement Window Installation by Local Fitters

We’re not a national chain. We’re a local team that understands the homes and weather of Surrey and South London, and our own experienced fitters carry out every installation.

Made-to-Measure Manufacturing

Each window is built to fit your openings exactly. You can choose side-hung, top-hung, fixed or flush casements, in a wide range of colours and finishes.

Free Survey and Measuring

We visit your home, take accurate measurements and talk through styles, glazing and finishes, with no pressure to buy. You’ll receive a detailed written quote afterwards.

Fitting Day

Most standard replacements take a single day. We protect your home, remove the old frames, fit and seal the new windows, then tidy up and check everything with you before we leave.

Certification and Guarantees

Our FENSA-registered fitters work to current Building Regulations, including Part L for thermal performance and Part Q for security. You’ll receive a FENSA certificate on completion, which you’ll need when you sell, plus our 10-year guarantee.

Aluminium Casement Window Replacement: Is It Time?

Windows rarely fail overnight. They slowly get colder, noisier and harder to use until one day you notice.

Signs Your Windows Have Had Their Day

Look out for draughts, condensation trapped between the panes, rotting or warped frames, stiff handles and heating bills that keep creeping up. If two or three of these sound familiar, replacement usually pays off.

What You Gain From Upgrading

You'll enjoy a warmer, quieter and more secure home, with far less upkeep. Aluminium frames don't rot, warp or need repainting, and fresh windows do wonders for kerb appeal and resale value.

Aluminium vs uPVC vs Timber

Aluminium gives the slimmest frames, great strength and a long life with minimal maintenance. Explore our Aluminium windows to see the full range of styles and finishes. uPVC is a popular budget-friendly choice with thicker frames, while timber has a classic look but needs regular painting and care. We fit all three, so we’ll give you an honest recommendation for your home.

Aluminium Casement Window Repair for Everyday Faults

Not every problem means a new window. We supply, replace and repair all window types, so we’ll fix what can be fixed.

Handles, Hinges and Seals

Worn hinges, stiff handles and tired seals cause most draughts and rattles. New hardware often makes a window feel like new.

Misted or Cracked Glass

Fogging between the panes means the sealed unit has failed. We can usually replace the glass without replacing the frame, and cracked panes can be swapped quickly, with safety glass if needed.

When Repair Stops Making Sense

If a frame is badly damaged, or several windows are failing at once, replacing them often makes more sense than paying for repeated repairs. We'll always be upfront about which route suits you.

Aluminium Casement Window Price Guide

Every home is different, so there’s no single price that fits every project. The cost depends on the size and number of windows, the type of glazing, your choice of colour and finish, the opening style, and how easy your property is to access.

The simplest way to find out is to ask us. We offer a free survey and a detailed written quote with no obligation. Customers often tell us they appreciated a fair, honest assessment without being sold extras they didn’t need.
