Replacement windows are new, made-to-measure windows fitted into your existing openings when the old ones have reached the end of their life. The tell-tale signs are draughts, condensation between the panes, rotting frames and energy bills that creep up each winter. For many homes, timber replacement windows are the ideal choice, pairing the charm of a traditional frame with the warmth and efficiency of modern double glazing.
Key takeaways
Windows rarely fail overnight, and the warning signs are easy to spot once you know what to look for.
On a windy day, try holding the back of your hand close to the window frame. If you can feel air moving, the seals or the timber have usually worn beyond what a fresh coat of paint can fix. Every draught lets warm air out and pushes up your energy costs.
A little condensation on the inside of the glass on a chilly morning is perfectly normal. Misting that’s trapped between the panes is a different matter. It usually means the seal has failed and moisture has found its way in, taking much of the insulating value of the glass with it.
Gently press the sill and the bottom of the frame with your thumb. If the wood feels soft or spongy, or looks darker than the rest of the frame, rot may well have set in. Surface damage can often be repaired, but once rot reaches the structure of the frame, a new window tends to be the better investment.
Windows are one of the main routes for heat transfer in a home. According to government figures, around 18% of the heat lost from a home escapes through its windows. If your heating seems to work harder every winter, older windows could be part of the reason.
uPVC windows are popular largely because they’re cheap to mass-produce. Timber often proves the better long-term choice, as this comparison shows.
| Timber windows | uPVC windows | |
| Appearance | Natural grain, slim profiles and a traditional look | Uniform plastic profile, often bulkier |
| Repairs | Damaged sections can usually be repaired | Usually replaced as a whole unit |
| Colour choice | Wide range of paints and stains, with a different colour inside and out if you like | Limited, factory-applied colours |
| Sustainability | Renewable material, with FSC-certified European oak available | Plastic-based |
| Period properties | Ideal, and often expected in conservation areas | Can look out of place on older homes |
Timber is a natural insulator, so a well-made wooden window frame works hand in hand with the glass to reduce heat loss. Our casement windows are rated A+ with double glazing and A++ with triple glazing.
Looks matter too. uPVC casement windows can sit awkwardly on a Victorian terrace, and aluminium windows rarely feel at home on a country cottage. Quality wooden windows add genuine kerb appeal, which you’ll enjoy every day and which buyers will notice if you ever decide to sell.
The right window type depends on the age and style of your property. Every window we build is made to measure to fit your openings exactly.
Casement windows open from the side or top and suit almost any home. Flush casement windows sit level within the outer frame, giving clean lines and a lovely period feel. Stormproof casements overlap the frame for added weather protection. We manufacture our casements to PAS 24:2022 security standards, with multi-point locking for extra peace of mind.
Sash windows are a much-loved feature of many Georgian and Victorian homes. We make box sash and sliding sash windows, with night vent locking so you can let in fresh air while staying secure.
Bay windows bring extra natural light and a real sense of space to a room. We also build custom windows in non-standard sizes where off-the-shelf frames won’t fit.
The right windows make a big difference to how warm and quiet your home feels. Ours come with a choice of glazing options:
Yes. Building regulations set minimum energy efficiency standards for new windows, so they keep your home warm and help lower your heating bills. Your new windows should also let in enough fresh air to help control condensation, often through small trickle vents built into the frame.
The good news is that all our replacement windows meet current building regulations, so you won’t need to worry about the technical detail. If you live in a listed building, a conservation area or a flat, it’s worth checking with your local planning authority before ordering, as extra rules may apply.
