We here at Nestor Shanahan Auctioneers believe that windows and external doors deserve far more attention during a property viewing than they often receive. Buyers naturally focus on the kitchen, bathrooms, bedrooms and overall presentation of a home, but the condition of the windows and doors can have a major impact on comfort, energy efficiency, security and future maintenance costs. What may appear to be a minor cosmetic issue could indicate a much larger expense after purchase.
Windows and external doors are among the most important elements separating a property from the outside environment. They influence how much heat is retained, how much noise enters the home and how secure the property feels. Before making an offer, buyers should look beyond appearance and assess how well these features are likely to perform over the coming years.
1. Check for Draughts and Heat Loss
Poorly fitting windows and doors can allow cold air into the property and warm air to escape. This can make rooms uncomfortable and increase the amount of energy needed to heat the home.
During a viewing, buyers should pay attention to:
-
Draughts around frames
-
Gaps around external doors
-
Cold air near window edges
-
Condensation between panes of glass
-
Rooms that feel noticeably colder than others
-
Curtains or blinds moving when windows are closed
Older single-glazed windows or deteriorating seals may be less energy efficient than modern double or triple glazing. Even where windows are double glazed, the age and quality of the units can affect their performance.
Replacing windows throughout a property can be a substantial expense, so buyers should factor the likely cost into their overall assessment.
2. Look Carefully at Frames and Surrounding Areas
The glass itself is not the only part of a window that matters. The condition of the frames and the areas surrounding them can reveal signs of deterioration.
Timber frames should be checked for:
-
Rot
-
Soft or damaged sections
-
Peeling paint
-
Water staining
-
Swelling or warping
uPVC and aluminium frames should also be inspected for cracks, damage, discolouration or failed seals. Around all window types, buyers should look for signs of damp, staining or water ingress on internal walls, window boards and reveals.
Damage may be caused by ageing materials, poor maintenance or defective installation. If there are signs of water penetration, it is important to establish whether the issue is isolated or part of a wider problem.
3. Test How Windows and Doors Operate
A window or door may look perfectly acceptable but still be difficult to use. Buyers should check whether windows open, close and lock properly, where possible during the viewing.
Look out for:
-
Windows that stick or do not close fully
-
Handles that are loose or damaged
-
Locks that do not engage correctly
-
Doors that scrape against the frame or floor
-
Hinges that appear worn
-
Gaps around door edges
-
Difficulty opening emergency escape windows
Windows that do not open properly may also create ventilation and safety concerns. External doors should close securely and fit correctly within their frames.
These may seem like small issues, but repairing or replacing hardware across a property can quickly add up.
4. Consider Security and Insurance Requirements
External doors and accessible windows play a significant role in the security of a home. Buyers should consider whether locks, handles and frames appear robust and fit for purpose.
Older doors may have outdated locking systems or weakened frames. Some windows may not have suitable restrictors, locks or safety features, particularly in upper-floor bedrooms or properties with young children.
Security improvements may include replacing locks, upgrading door cylinders, fitting additional security features or replacing entire doors and frames. Buyers should also be aware that insurers may have specific requirements relating to locks and security, particularly for unoccupied periods.
A property that requires extensive security upgrades may involve more work and expense than initially expected.
5. Think About Long-Term Maintenance and Replacement Costs
Windows and external doors are long-term investments, but they do not last indefinitely. Their lifespan depends on the materials used, installation quality, exposure to weather and level of maintenance.
Coastal and exposed properties may experience more wear from wind, rain and salt air. Older rural homes may have traditional windows that require specialist repair or replacement. Listed or protected structures may also have restrictions affecting what changes can be made.
Buyers should ask whether windows or doors have been replaced, when the work was carried out and whether guarantees or installation records are available. If replacement is likely in the near future, it should be included in the buyer’s budget alongside other planned improvements.
A Small Detail With a Major Impact
The condition of windows and external doors can influence much more than the appearance of a property. They affect heating bills, comfort, ventilation, noise, security and the cost of maintaining the home.
Buyers should take time during a viewing to inspect these features carefully rather than assuming they are in good condition because the property looks well presented. A fresh coat of paint or attractive curtains can disguise ageing frames, damaged seals or poor operation.
A thorough inspection, supported by a professional survey where appropriate, can help buyers understand whether the windows and doors are simply in need of minor maintenance or likely to require significant investment.
