Troubleshoot Common Issues with Windows & Doors

Windows and doors can develop common problems over time. Such as condensation, mould, draughts, broken handles, or leaking conservatory roofs. This guide from Jewel Windows covers how to identify, troubleshoot, and resolve these issues for a safer, more efficient home.

1. How to Stop & Prevent Condensation on Windows?

What Causes Condensation?

Condensation on windows forms when warm indoor air meets a cooler glass surface. Factors that contribute to condensation include:

• High indoor humidity from cooking, showerin or drying clothes

• Cold surfaces from older single-glazed panes or poor insulation

• Poor ventilation

So now that you know the factors that contribute to condensation, how do you reduce or eliminate it? Ventilation is the first step. Choose windows that incorporate trickle vents for controlled ventilation as well as adding extractor fans to your home. if you currently have single glazed windows, we would highly recommend upgrading to double or triple glazing for better thermal performance as well as improving insulation around the window frames.

If you are currently suffering from condensation issues, as a short term solution, you can wipe surfaces daily to avoid mould buildup around window frames and sills. To reduce the indoor moisture levels, incorporate dehumidifiers across your home. But if you have condensation on the outside of your windows and doors, this is typically harmless due to the temperature difference between indoors and outdoors.

2. How to Deal with Mould Around Windows & Doors?

Persistent condensation can lead to mould growth, especially on frames or nearby walls. While on the short term, this may seam harmless, mould around windows, doors and frames can cause serious long term issues. Including health or structural problems.

As we discussed above, you can clean the mould daily and ensure that the affected areas are fully dry after cleaning. But to prevent recurrence and for a sustainable solution, you need to eliminate the core sources of moisture by ensuring good ventilation and airflow.

3. Draughty Windows & Gaps Between Frame and Glass

If you feel cold air or see damp spots around windows or doors, start with checking for seal failure as old or damaged seals allow air and moisture in. If this is the case, resealing windows can help with keeping out draughts and heat loss. However, if you have large gaps, these require professionals to realign the frame or even a replacement in some cases.

4. Broken Window & Door Hardware

Window Handle Issues

If your window handle is broken or the window won’t open, follow these steps:

• Check for obstructions in the frame or locking mechanism.

• Tighten loose screws or replace the handle if worn.

• If locks or gears are stripped, contact a specialist to fix window handle or replace broken handles.

Door Lock Problems

When a door won't lock when closed, it could be due to misalignment, worn strike plates, or issues in the latch mechanism. Adjust hinges, align the strike plate, or replace broken parts.

5. Conservatory Roof Leaks & Repairs

While its not related to windows and doors, conservatory roof leaks are a common issue seen across homes. Start by identifying the leak and its exact location. Common areas include ridge cappings, gutter joints, or glazing seals. For minor leaks, you can apply a conservatory roof sealant or reseal the joints.

For more serious or persistent leaks, consult with professionals like Jewel Windows and consider a replacement roof.

6. Preventative Maintenance Tips

There are also some preventative maintenance that you can carry out to avoid experiencing issues with windows and doors. Including:

• Inspect seals, hinges, handles, and sills on your windows and doors annually.

• Keep drainage channels clean to prevent water build-up.

• Lubricate moving parts (handles, locks, hinges) to prevent wear and sticking.

• Consider double and triple glazing upgrades for better insulation and less condensation.
