While windows don’t need replacing as often as some other home features, they do eventually wear out and lose their effectiveness. This could impact their efficiency, security, and appearance.
At Northwich Glass, we’ve been helping homeowners across Cheshire with window replacement since 1959.
We’ve written this piece to help you understand the status of your windows and whether you should think about replacing them.
Signs Your Windows Need Replacing
Sometimes your windows will clearly tell you when they need replacing. Here are the most common indicators:
Draughts and Cold Spots
If you can feel air coming through when your windows are closed, that’s a clear sign your existing window seals have failed. These draughts make your heating system work harder and increase your energy bills.
There are a few ways to check for draughts. Firstly, and most simply, with your hand. If you aren’t sure, you can run a lit candle across the edges of the frame on a windy day. If the flame flickers, then wind and cold air is being let in.
Difficult Operation
Windows should open and close smoothly. If your window sash sticks, jams, or requires force to operate, the window’s functionality has been compromised. This is especially common with older windows where the mechanisms have worn down or wooden frames have warped over time.
Whilst this might seem to be just an annoyance, this could impact the window’s security, making the lock and frames vulnerable to forced entry.
Condensation Between Glass Panes
Condensation on window frames is normal and often unavoidable. However, if you notice fogging or water droplets between the glass panes that can’t be wiped away, the seal has failed, and the insulating gas has escaped.
This significantly reduces the window’s insulation properties, making the windows very inefficient and likely costing you in heating. Seal failure almost always requires completely new windows.
Visible Damage
Cracked glass, rotting wood, or damaged window frames all compromise security and efficiency. Even small cracks can worsen over time, especially during temperature fluctuations.
Rising Energy Costs
If your heating bills keep climbing despite similar usage patterns, your windows might be letting heat escape. Windows account for a large amount of energy loss from your home, and if they’re inefficient, they’ll account for even more.
During this time of high energy bills, efficient windows are even more crucial.
Mould or Moisture Issues
Excess condensation on windows often leads to mould growth on sills, frames, or surrounding walls. This happens when warm indoor air hits cold window surfaces.
Beyond being unsightly, this moisture can damage your home, create mould, rot timber frames and potentially affect your health.
How Long Do Windows Last?
The lifespan of your home windows varies based on materials, installation quality, maintenance, and local climate conditions. Here’s what to expect from the window types we install at Northwich Glass:
uPVC Windows
Our uPVC windows typically last 20-30 years when properly installed. They don’t rot, warp, or corrode like some materials, making them a durable, low-maintenance option for Cheshire homeowners. They require minimal upkeep beyond occasional cleaning.
Aluminium Windows
Aluminium windows are exceptionally durable, often lasting 30-40 years or more. They withstand harsh weather conditions without warping or corroding and maintain their functionality and appearance for decades. The powder-coated finishes we use resist fading and scratching.
Benefits of Window Replacement
Replacing your windows can give you a series of benefits.
Improved Energy Efficiency
Energy efficiency is a priority in our windows; we use advanced glazing technologies, better frame insulation, and tighter seals. This improved home’s energy efficiency translates to lower energy bills and a warmer home.
Added Security
Our windows incorporate multi-point locking systems and stronger materials that better protect against intruders. This is particularly important for ground-floor windows that are more vulnerable to break-ins.
Better Comfort
Replacement windows eliminate draughts, cold spots, improvement the efficiency of your home and create more consistent temperatures.
Reduced Maintenance
Modern uPVC and aluminium windows require minimal upkeep compared to older wooden frames that need regular painting and repair. No more scraping, sanding, and repainting every few years. They also offer an upgrade on durability.
Increased Home Value
Quality window replacement can boost the value of your home while improving its appearance. Estate agents often highlight new windows as a selling point that signals the property has been well-maintained.

Is it Time to Replace Your Windows?

Frequently Asked Questions
Can I replace just one window, or do I need to do all of them at once?
You can absolutely replace just one window if needed. However, many homeowners choose new replacement windows on at least one side of the home at the same time, as it’s more economical.
Does a draught mean I need to replace my windows?
Persistent draughts typically indicate seal failure, which affects both your security and energy bills. With today’s high heating costs, even small drafts can add up to significant money wasted. If you’re feeling cold air coming in, warm air is escaping – and that means your heating system is working harder than it should.
Will new windows really save money on energy bills?
Replacing old windows with modern types of windows is an excellent choice to improve your home’s energy efficiency. Many homeowners see noticeable reductions in their heating costs.
