Windows do far more than just frame a lovely view — they provide security, keep our homes warm, block out noise, and help maintain a comfortable living environment. Yet, like all parts of a home, windows don’t last forever. Over time, hinges start to wear, locks become stiff or loose, seals break down, and double glazing can become misted or inefficient.
When these issues arise, the question many homeowners ask is:
Is it cheaper to repair the problem or just replace the entire window?
This decision isn’t always straightforward. Costs, energy efficiency, security, and even environmental considerations come into play. In this guide, we’ll explore each element in detail, so whether you’re searching for window repairs near me, window repairs Poole, or double glazing repairs Bournemouth, you’ll know exactly where your money is best spent.
Before we jump into repair vs replacement, it’s worth knowing why windows fail in the first place.
Age: Older windows naturally suffer from wear and tear. Materials degrade, especially seals and moving parts.
Weather Exposure: Constant exposure to wind, rain, UV rays, and temperature fluctuations causes expansion, contraction, and eventual failure of parts.
Poor Maintenance: Lack of cleaning, lubrication, and inspections speeds up deterioration.
Manufacturing Quality: Budget windows often use cheaper materials that have a shorter lifespan.
Installation Issues: Incorrect installation can put stress on hinges, seals, and locks, leading to premature breakdown.
Stiff operation or resistance when opening/closing.
Gaps between sash and frame when shut.
Noticeable draughts.
Visible corrosion or bent hinge arms.
Handles that wobble, stick, or won’t turn smoothly.
Key not fitting or jamming in the lock.
Lock not engaging fully — posing a security risk.
Drafts or whistling sounds in windy weather.
Condensation or water ingress around the frame.
Cracked or brittle rubber seals.
For double glazing, a failing swiggle strip (the spacer between panes) can lead to misting.
Cloudy or misted glass inside the sealed unit.
Noticeable drop in room temperature.
Increased outside noise.
Water between the panes.
Cost: £50–£90 per window (varies with hinge size/type).
Lifespan Gain: 10–15 years if well maintained.
Advantages: Quick fix, inexpensive, restores smooth operation, stops drafts.
Drawbacks: Won’t help if seals or glass are also failing.
Example: A homeowner in Bournemouth had stiff hinges on two upstairs windows. For £160 total, both were replaced and now operate like new — far cheaper than £800+ for full replacements.
Cost: £40–£80 per window.
Lifespan Gain: 10+ years.
Advantages: Restores security quickly and cheaply.
Drawbacks: Doesn’t address underlying frame wear or poor energy efficiency.
Example: In Poole, a ground-floor uPVC window lock jammed. A quick £55 repair restored both security and peace of mind — a fraction of full replacement costs.
Cost: £20–£50 for rubber seals, £60–£120 for resealing double glazing with swiggle strip.
Lifespan Gain: 5–10 years.
Advantages: Reduces drafts, improves insulation, prevents moisture damage.
Drawbacks: If double glazing is already blown, this won’t fix internal condensation.
Example: A home in Ferndown had a failing swiggle strip on a kitchen window. For £85, the seal was replaced, cutting down heating bills and extending the window’s life.
Cost: £80–£150 per unit.
Lifespan Gain: 15–20 years.
Advantages: Restores clarity, insulation, and energy performance.
Drawbacks: Costs more than hinge/seal repairs but still cheaper than replacing the frame.
Example: In Bournemouth, a misted patio door unit was replaced for £140. The frame stayed in place, saving over £600 compared to a full new door.
Deciding whether to repair hinges, locks, seals, or replace a window comes down to balancing cost, condition, and long-term value. In most cases, if the window frame is still solid, repairing individual components is the more cost-effective option. A hinge or lock repair can be done quickly and cheaply, restoring full function and security for years to come. Replacing seals — or addressing a failed swiggle strip — can make a noticeable difference to comfort and energy efficiency without the expense of a full replacement.
However, not all problems are isolated. If your double glazing has blown and you’re also dealing with stiff hinges, faulty locks, and warped frames, the costs of multiple repairs can start to add up. In these situations, investing in a brand-new window could save you money in the long run, particularly if your current windows are more than 20 years old and lacking in modern energy efficiency.
By understanding the typical costs, lifespan improvements, and environmental pros and cons, you can make an informed, confident decision that suits both your home and your budget. Whether you’re in Bournemouth, Poole, Ferndown, or simply searching for “window repairs near me,” the principle remains the same — fix what you can, replace what you must.
