If your windows are old, outdated, not functioning fully, or have lost their energy efficient properties, it is time for them to get replaced.

But let’s not rush into things. New double glazing is a big investment.

At The Advanced Group, we want to give you all the facts so you can make the smart choice when it comes to window replacement.

Why and When You Should Consider a Window Upgrade

Sash windows, casement windows, French windows, tilt-and-turn.

Windows are designed to last for decades. However, unfortunately, they are not built to last forever.

Before we get started on when is the best time to invest in new windows, here is the signs to watch out for to help you with your decision.

Single Glazing? It’s Time to Upgrade

If your house still has single glazing, then you are really missing out.

Single glazing falls so far behind double glazing in terms of energy efficiency and savings that it is a legal requirement that all new builds in Scotland have double glazed windows.

Heating Costs Rising

Despite double glazing’s superior energy efficiency, it doesn’t last forever. Any damages to the seal can affect how well it is working.

Increased energy bills can be a sign of trouble.

Luckily, new double glazing is much better than outdated models. Innovative features such as thermo spacer bars, low-e technology, and UV-reflective glass greatly reduce heat loss, meaning investing in new windows can save you even more money.

Persistent Draughts Around The House

It isn’t just the bills that suggest it is time to replace and upgrade.

Feeling draughts of cold air near the frame is an indication that the seals have degraded. No amount of heating will be able to stop the gusts sneaking into your home.

Rotting Window Frames

Wooden window frames can be susceptible to water damage, especially in Scotland’s wet climate. This can lead to rot and water seeping into your home.

The Advanced Group specialises in uPVC frames because of their durability to the climate, and we will be happy to guide you through our extensive range.

Condensation Inside or On The Panes

Older double glazing is not as well insulated as newer models.

The difference between the warm air inside and the cold pane can cause condensation to form on the glass inside. If it’s frequent and left unmanaged, it can bring damp and mould concerns in a property and may damage window seals over time.

Condensation in between the panes is a sign of an even bigger problem.

A foggy, blown, or misted window happens when the airtight seal of your double-glazed windows has failed, increasing the energy consumption of your home.

Best Time of Year for Double-Glazed Window Replacement

The best time to replace your windows and doors with improved energy-efficient installations, really depends on you and your household.

Let’s walk you through all the benefits of each season to help you with your window installation decision.

Spring and Summer Time – Popular Season for Home Improvements

Spring and summer are popular periods for homeowners to consider upgrades and renovations.

The days are lighter and warmer, which means there are fewer weather delays and there is more flexibility for installation times.

By choosing to install energy-efficient windows during the warmer months, your home won’t be blasted by cold air. This helps minimise disruption to your living.

Autumn – New Windows in Time for the Cold

Although spring and summer are great times for easy installation. It usually isn’t until the autumn period where homeowners start noticing that their current windows aren’t as energy efficient as before.

This makes autumn one of the more popular times of the year to install windows.

The positive of replacing windows in autumn is that you will benefit from improved insulation in time for the cold winter ahead.

The slight negative? You might not have as much flexibility in choosing your date and time.

At The Advanced Group, we always try to work around your schedule wherever possible for hassle-free installations.

Even in the coldest season, you can benefit from installing new windows.

Inefficient windows greatly impact on your living situation and your energy bills, by investing in new windows during winter sees instant benefits.
