When people think about window cleaning, they naturally think about the glass.

But the glass is only part of the window.

Over time, uPVC window frames and sills can collect dust, cobwebs, traffic film, bird mess, general dirt and even green organic growth. If the frames are dirty, freshly cleaned glass can still leave the whole window looking a little tired.

So can normal window cleaning remove dirt from uPVC frames and sills?

In many cases, yes.

At PurePort, our regular window cleaning service includes the glass, frames and sills, helping to keep the complete exterior of the window looking clean rather than concentrating on the glass alone.

Why do uPVC window frames get dirty?

Window frames are constantly exposed to the weather.

Rain, wind and general airborne dirt gradually settle on the uPVC, particularly around corners, seals and the bottom of the frame.

Sills can collect even more because water naturally runs down towards them.

Depending on the property, you may also see:

• Dust and general grime
• Cobwebs
• Bird mess
• Green algae or organic growth
• Dirt around corners and seals
• Marks caused by water running down the building
• Traffic and airborne pollution

If the windows are cleaned regularly, much of this can be prevented from building up heavily in the first place.

Are window frames normally included in window cleaning?

Not always.

Different window cleaners provide different levels of service, so it is worth checking exactly what is included.

At PurePort, our regular window cleans include the:

• Glass
• Frames
• Sills

We use a pure water cleaning system with a water fed pole, which allows the brush to work across both the glass and surrounding uPVC.

For us, cleaning the whole window makes more sense than leaving clean glass surrounded by dirty frames.

How does pure water clean uPVC frames?

Our water fed pole system uses a specialist brush to agitate the dirt on the window.

Purified water continuously flows through the brush, helping to loosen and rinse away dirt from the glass, frames and sills.

The process is particularly useful for regular maintenance because the frames are being cleaned each time rather than being left until the dirt becomes heavily established.

Once everything has been cleaned, the window is rinsed with purified water and left to dry naturally.

If you would like to understand the system in more detail, we have also written a guide explaining what pure water window cleaning is and how it works.

Can very dirty window frames be cleaned?

Usually, a considerable amount of dirt can be removed.

A window that has not been cleaned properly for a long time may simply need more attention on the first visit.

We regularly find that the first clean requires more work around frames, sills and corners because dirt has been allowed to accumulate.

Once the window has been cleaned thoroughly, regular visits make maintaining it much easier.

This is one of the reasons we treat the first window clean slightly differently from ongoing maintenance cleans.

You can read more in our guide to what is included in a first window clean.

Will window cleaning make old uPVC look new again?

This is where it is important to distinguish between dirt and the condition of the uPVC itself.

Professional window cleaning can remove a lot of surface dirt and organic build-up, which can make frames look considerably fresher.

But cleaning cannot always reverse permanent staining, fading, ageing or discolouration within the material itself.

Older white uPVC, for example, can sometimes become faded or discoloured over many years.

If the issue is sitting on the surface, cleaning may make a significant difference.

If the uPVC itself has changed colour, normal window cleaning will not necessarily return it to its original appearance.

What about green window frames and sills?

Green marks are often caused by algae or other organic growth developing where surfaces remain damp.

This commonly appears around:

• Window sills
• Frame corners
• Shaded areas
• Areas close to plants and trees

Regular cleaning can help remove surface growth and prevent it from becoming heavily established.

If the uPVC is particularly dirty or has years of built-up organic staining, it may require more work than a normal maintenance window clean.

Why does regularly cleaning the frames matter?

One of the benefits of regular window cleaning is that dirt does not get the same opportunity to accumulate.

There is a big difference between maintaining a reasonably clean frame every few weeks and trying to remove several years of built-up grime in one visit.

Regularly cleaning the glass, frames and sills helps keep the entire window looking better throughout the year.

It can also make future cleans more straightforward because each visit is maintaining the previous standard rather than starting again.

What about the uPVC around fascias and soffits?

Window frames are not the only exterior uPVC on most homes.

Fascias, soffits, guttering and other white exterior surfaces can also become dirty and develop green growth over time.

These areas are not normally part of a standard window clean because they are a separate exterior cleaning job.

PurePort also provides fascia and soffit cleaning in Portishead for homeowners who want to freshen up more of the exterior of their property.

Sometimes cleaning the windows, frames, fascias and soffits together can make a surprisingly noticeable difference to the overall appearance of a home.

How do I keep my uPVC window frames looking clean?

The simplest answer is regular maintenance.

Once frames and sills have been brought up to a good standard, having them cleaned as part of each regular window visit helps prevent heavy dirt from building up again.

That is why our service focuses on the complete window.

We want the glass to look clean, but we also want the frame and sill around it to look cared for.
