Double Glazing London, London Windows And Doors

If your home in London still has older single glazed or worn out double glazed units, you are very likely losing a significant amount of heat every single day. Draughty frames, misted glass, and seals that have given up all let warm air out and cold air straight in, and your boiler has to work harder to compensate for every degree you lose.

That extra strain on your heating system shows up on your energy bills month after month. Many London homeowners are surprised when they look back over a year and realise just how much they have been spending to heat a home that is effectively leaking warmth through its windows and doors. It is not just uncomfortable, it is genuinely costly.

How A+ Rated Windows And Doors Actually Change Things

Modern A+ rated double and triple glazed units are built to a completely different standard than what most older properties have fitted. The glass itself uses advanced low emissivity coatings that reflect heat back into the room rather than letting it escape. Argon gas filled units add another layer of insulation between the panes, and uPVC or timber composite frames provide far better thermal performance than older aluminium or degraded uPVC profiles. Fitted properly, your rooms hold their temperature for longer, your thermostat does not need to kick in as often, and you notice the difference from the first cold evening. All products supplied and installed by London Windows And Doors carry an A energy rating as standard, with A+ options available across much of the range.

The Real Cost Of Keeping Old Windows And Doors Going

Older units rarely fail all at once. They tend to deteriorate gradually, and many homeowners end up spending money on repairs, resealing, adjusting hinges, and replacing handles over several years without ever fully solving the underlying problem. A draughty composite door that has warped in its frame, or a double glazed unit that has blown and gone misty, costs money to patch up each time. Over a five to ten year period, those repair costs add up considerably. Replacing the unit outright with a properly fitted, guaranteed product often works out cheaper in the long run, and you are not dealing with the same issues returning every winter. Every installation from London Windows And Doors comes with a full ten year guarantee, so once it is fitted, you are covered.

Six Ways New Windows And Doors Save You Money Over Time

  • Lower heating bills as less warm air escapes through frames and glass
  • Reduced maintenance costs because uPVC and composite materials need very little upkeep compared to timber or older aluminium
  • Better security with multi point locking systems fitted as standard, reducing the risk of break ins and potential insurance claims
  • Improved home value as buyers and valuers take note of energy efficient glazing and modern doors when assessing a property
  • No more repair bills on failing seals, stiff mechanisms, or draughty frames once new units are properly installed
  • Consistent indoor temperatures meaning you rely less on portable heaters or leaving your central heating on for longer periods
