Double glazing is one of the smartest investments you can make for your home. It keeps warmth inside, reduces energy bills, and improves security. But like any part of your home, it needs a little care. The truth is, most major double glazing failures start with small issues that could have been fixed quickly and affordably.
At RPS Double Glazing Repairs in Dorset, we’ve seen it all—from minor draughts that turn into full unit replacements, to locks that jam so badly the whole window has to be replaced. The good news? You can avoid all that with a little attention to the early warning signs.
Here’s a closer look at the tiny fixes that can save Dorset homeowners from big headaches.
It’s easy to brush off small issues. A little breeze coming through the window? Just wear a jumper. A stiff lock? Push harder. But these little inconveniences often hide underlying problems that are steadily worsening.
Draughts suggest your seals are failing, which can let in cold air, moisture, and even mould.
Condensation between panes means the insulating barrier has gone, drastically reducing efficiency.
Sticking locks or handles aren’t just annoying—they can strain hinges, warp frames, and reduce security.
Chips in the glass can grow into cracks that weaken the entire pane.
Addressing these early doesn’t just stop bigger failures—it also saves you money and keeps your home comfortable all year round.
Draughts are one of the first signs of a problem with double glazing. You might feel cold air around the edges of the frame, or notice your heating has to work harder to keep the room warm.
In most cases, draughts happen because the rubber seals around the glass or frame are worn out. Replacing these seals is quick, inexpensive, and makes an immediate difference. It restores the airtight barrier, improves energy efficiency, and keeps your heating bills down.
Why it matters in Dorset: Our coastal winds can put extra pressure on seals. If you live near the sea—say in Bournemouth, Poole, or Weymouth—your windows are more exposed to salty air and moisture, which wears seals faster. Catching this early protects your home from unnecessary heat loss.
If you’ve ever struggled to open or close a window, you’ll know how frustrating it can be. But beyond the annoyance, stiff locks and handles signal misalignment or worn parts.
The fix could be as simple as adjusting the hinges, lubricating the mechanism, or replacing a small component. Left untreated, though, the strain can cause permanent damage to the frame or lock, and in some cases, the window might become stuck shut or won’t lock securely.
Why it matters in Dorset: Security is a big concern for homeowners, especially in busy areas like Bournemouth or Dorchester. A faulty lock can leave your home vulnerable. Sorting it quickly keeps your property safe without the need for a costly full replacement.
We’ve all seen misty windows that won’t clear, no matter how much you wipe them. This happens when the seal around the double glazing unit has failed, allowing moisture to get trapped between the panes.
At first, it’s just unsightly. But over time, it reduces the insulation properties of your windows, meaning you lose heat faster and pay more for energy. Eventually, the unit may need replacing.
A timely fix involves replacing just the sealed glass unit, not the whole frame. This is far more affordable and keeps your windows looking fresh and performing efficiently.
Why it matters in Dorset: With our mix of coastal humidity and colder inland nights, condensation problems are common here. Catching it early can make all the difference.
Over time, the sealant around your windows can crack, peel, or separate from the frame. It doesn’t always look like a big problem, but even a tiny gap can let in cold air and moisture.
Water ingress is especially dangerous—it can damage plaster, rot wooden frames, and encourage mould growth inside your home. Resealing is a simple, affordable job that creates a watertight finish and keeps your windows performing at their best.
Why it matters in Dorset: Damp problems can spread quickly in coastal properties. By resealing before water gets in, you save yourself expensive repair bills later.
Glass is surprisingly resilient, but even a small chip or crack can weaken a pane. With temperature changes, the crack can spread, leaving you with a serious break that requires full replacement.
Early intervention—either with a resin repair or by replacing the affected pane—prevents further damage. It’s a classic example of spending a little now to avoid a big cost later.
Why it matters in Dorset: Sudden weather shifts are common here—sunshine one moment, heavy rain the next. That temperature variation puts extra stress on weakened glass, making small cracks grow faster.
