Casement Windows, Measured and Fitted Properly

The most reliable signs are condensation or fogging between the panes, which means the sealed unit has failed and cannot be repaired; noticeable draughts when the window is fully closed; frames that have warped, cracked, or become difficult to open and close; and glass that feels cold to the touch on a dry day, which indicates significant heat loss. If your double glazing is more than 20 years old it is worth having it assessed regardless — the efficiency gap between older units and modern A-rated glazing is considerable. If you are unsure, get in touch and we will visit and give you a straight answer.

Replacing everything at once is more cost-effective and delivers the full thermal and security improvement immediately. It also ensures a consistent appearance across the whole property, which matters for both kerb appeal and resale. That said, a phased approach is entirely reasonable if budget is the constraint — most homeowners prioritise the windows causing the most problems, or those most visible from the street, and work through the rest over time. We are happy to work either way and will not push you towards a larger project than makes sense for your situation.

Our fitters arrive at the agreed time and work through each opening one at a time, so your home is never left exposed or unsecured during the process. Furniture and flooring near the windows are protected before work begins, and the team tidies as they go. Old frames and glass are removed and taken away — you do not need to arrange disposal. For a full-house replacement on a typical South Bucks property, most jobs are completed within one to two days. Before we leave, every window is tested — opens, closes, and locks correctly — and we walk you through the work to make sure you are happy.

In most cases, yes. Casement windows can usually be replaced like-for-like in conservation areas without requiring planning permission, particularly when the new frames closely match the original in profile and colour. Where specific requirements apply — such as maintaining timber-effect profiles, particular colour finishes, or glazing bar configurations — we know what the local authorities across Windsor, Beaconsfield, and Gerrards Cross typically expect and will advise you correctly before any work is agreed. If consent is needed for anything, we explain clearly what that involves so there are no surprises.

A single window typically takes two to three hours. A full house — usually eight to fourteen windows depending on the size of the property — is completed within one to two days. We will give you a clear timeframe in your written quote before any work begins.

uPVC is more affordable, low maintenance, and thermally efficient — the right answer for most homes. Aluminium has significantly slimmer frames, which means more glass and more light, and carries a more refined finish. For premium properties or contemporary extensions, aluminium is often worth the additional investment. We will give you our honest view on which suits your property when we visit.

If your frames are discoloured, draughty, or more than 20 years old, replacement is almost always better value. Modern casements are dramatically more thermally efficient than early 2000s double glazing, and the difference in heating costs accumulates quickly. We will give you our honest assessment during the visit. If your windows still have usable life in them, we will tell you.

Yes. We bring samples to every home visit — frame colours, woodgrain foils, glass options, and hardware finishes. Most people find it much easier to make decisions when they can see the options against their actual property in natural light rather than from a brochure.

For most window and door replacements, no. Like-for-like replacements fall under permitted development rights and require no planning permission. If your property is in a conservation area — parts of Windsor and Beaconsfield Old Town, for example — or if it's listed, there may be restrictions on colour, style, or material. We know the local areas well and will flag anything relevant during your visit.

Yes. FENSA registration means every installation we complete is certified to meet current building regulations, and the work is registered with your local authority automatically. This is important if you ever sell your home — solicitors will ask for it. You don't need to do anything; we handle the registration on your behalf.

Our installations come with a 10-year guarantee as standard, covering both frames and sealed glazing units. Combined with FENSA registration and our full public liability insurance, you're protected throughout the installation and long after completion.

Yes. We remove all old frames and glass and dispose of them responsibly. We also leave your home clean and tidy at the end of every job — it's part of how we work, not an optional extra.

We don't consider a job complete until you're satisfied. If something isn't right, tell us and we'll fix it. Our reputation in South Bucks has been built over 20 years — we have every reason to make sure you're happy.
