Windows are one of the most important features in any home. They let in natural light, provide ventilation, and help keep your property warm and secure.
But over time, windows can develop problems—especially in places like Newcastle, where wind, rain, and cold weather put them to the test all year round.
At Windows and Doors Newcastle, we’ve worked on homes across the North East, from terraces in Heaton to semis in Gateshead and detached homes in Ponteland. We see the same window problems come up time and time again.
In this guide, we’ll walk you through the most common window issues in Newcastle homes—and how to fix them quickly, safely, and cost-effectively.
1. Draughty windows
Draughts are one of the most common complaints from homeowners.
If you feel cold air coming through even when your windows are shut, it usually means there’s a problem with the seals, hinges, or alignment.
Common causes:
- Perished or cracked rubber seals
- Loose hinges or poorly aligned sashes
- Gaps between the frame and wall
- Age-related wear and tear
How to fix it:
- Replace worn weatherstripping or gaskets
- Adjust hinges or tighten fixings
- Seal gaps around the frame with caulk or expanding foam
- In some cases, consider upgrading to modern, energy-efficient units
We regularly fix draughty windows across Newcastle and often see a big improvement in warmth and comfort with just a few adjustments.
2. Condensation between panes
If you see mist or water trapped inside the double glazing, it means the sealed unit has failed.
This is more than just a cosmetic issue. It affects the insulation of your window and can lead to further problems like mould or frame damage.
Causes:
- Broken seals allowing moisture to enter
- Old or low-quality double glazing
- Sudden temperature swings causing stress fractures
How to fix it:
- Replace the affected sealed unit
- Upgrade to a higher-rated double or triple-glazed unit
- Ensure the new unit is gas-filled and properly sealed
We replace failed glass units without needing to change the entire frame in most cases. It’s a fast, affordable fix that restores energy performance.
3. Windows that won’t open or close properly
If your window sticks, scrapes, or feels stiff, it’s usually due to alignment issues or worn-out hardware.
This is a common problem in older homes across Newcastle, especially where windows have been painted shut or fitted poorly in the past.
Causes:
- Swollen frames from moisture
- Warped sashes due to temperature changes
- Loose or rusted hinges
- Bent or broken opening mechanisms
How to fix it:
- Clean and lubricate hinges and handles
- Adjust or tighten screws and fixings
- Replace worn friction stays or tilt latches
- If frames are warped, consider a full window replacement
We offer adjustment services throughout Newcastle and can usually restore full movement with a simple service visit.
4. Leaking windows
Water coming in through your windows is a sign that something is wrong with the seals, frame, or drainage.
It’s often first noticed during heavy rain or storms, and if ignored, can lead to mould, damp, or structural damage.
Causes:
- Blocked drainage holes in the window frame
- Failed silicone or perimeter sealant
- Cracks in the frame or glazing bead
- Poor installation or movement in the wall
How to fix it:
- Clear all drainage holes and weep vents
- Remove and reseal around the frame
- Replace damaged gaskets or trim
- In severe cases, remove and reinstall the window properly
If you live in an exposed part of Newcastle like the coast or high ground, regular checks are a smart move.
5. Stiff or noisy handles
Over time, window handles can become difficult to turn or make squeaking noises.
This is usually due to lack of lubrication or internal wear, and it’s an easy problem to sort with basic maintenance.
How to fix it:
- Apply silicone spray or light oil to moving parts
- Remove dust or dirt from handle joints
- Check for loose screws and tighten as needed
- Replace handles if they’re cracked or faulty
We carry replacement parts for most popular window brands used across the UK, and a handle swap takes just minutes.
6. Glass feels cold or room loses heat quickly
If the glass on your windows feels very cold to the touch—or the room feels cold even with heating on—it could be a sign that your glazing is outdated or inefficient.
This is especially true in homes still fitted with early-generation double glazing from the 90s or 2000s.
How to fix it:
- Upgrade to modern A-rated or A+ rated glazing
- Consider triple glazing in colder, north-facing rooms
- Install thermal curtains or blinds as a temporary measure
We fit high-performance windows with low U-values designed to keep Newcastle homes warmer through the long winters.
7. Discolouration or staining on frames
White uPVC frames are known for their durability—but they can still discolour over time, especially with exposure to pollution, algae, or smoke.
Yellowing, staining, or mould growth are all signs your windows need a clean and maybe a bit of maintenance.
How to fix it:
- Clean with warm water and non-abrasive cleaner
- Use uPVC restorer products for stubborn marks
- Reseal joints or trims where mould is building up
- Avoid bleach or harsh chemicals that can damage the finish
Regular cleaning can help avoid long-term staining, especially in homes near busy roads or the coastline.
8. Cracked or chipped glass
Even small chips or cracks in your window glass can spread over time—especially in freezing weather or with repeated impact.
Causes:
- Accidental knocks from furniture, balls, or tools
- Natural expansion and contraction
- Poor installation or low-quality glass
How to fix it:
- Replace the damaged sealed unit
- Don’t attempt to tape or seal the crack—this won’t stop it spreading
- If the frame is fine, you won’t need a full window replacement
We offer quick-response glass replacement across Newcastle and can often source exact matches for older window styles.
9. Fogging on the inside of windows
If you’re seeing condensation inside your home—on the room side of the glass—it’s a sign of excess humidity, not a window fault.
It’s still worth addressing, as high humidity can cause mould or damage to sills and plasterwork.
How to reduce indoor condensation:
- Improve ventilation with extractor fans or trickle vents
- Use a dehumidifier in high-moisture rooms like kitchens or bathrooms
- Keep blinds slightly open to allow airflow
- Don’t block radiators below windows
If trickle vents are stuck or blocked, we can service them during a maintenance visit.
10. Broken window locks or security concerns
Security is one of the top reasons Newcastle homeowners call us out.
Old or faulty locks leave your home vulnerable, especially on ground-floor or side-facing windows.
How to fix it:
- Replace broken locks or locking handles
- Install new security catches or restrictors
- Upgrade to windows with multi-point locking systems
- Add window alarms or laminated glass for extra protection
We often recommend security upgrades as part of a wider window replacement or service.
