External cleaning

Professional conservatory window cleaning

We use two primary cleaning methods to achieve a flawless finish on your windows, each offering exceptional results.

Water-fed pole window cleaning

  • Extended reach for full coverage

    Our high-reach, water-fed pole system cleans conservatory windows and roofs with ease. Equipped with a 22-meter carbon fiber pole, we make sure every corner of your conservatory’s glass surfaces is thoroughly accessible.

  • Powerful dirt removal

    Purified water effectively removes dirt, minerals, and chemicals, leaving glass crystal clear without streaks or residue.

  • Eco-friendly cleaning

    Using only purified water, this method avoids harsh chemicals and is approximately 42% more cost-effective than traditional methods.

  • Gentle yet thorough

    Designed to reach every nook and cranny, this method is perfect for conservatory roofs, reducing risk to your property and ensuring a safe, efficient clean.

Traditional conservatory window cleaning

For areas not accessible by our water-fed pole system, our cleaners use the traditional squeegee and detergent method to remove dirt, stains, and fingerprints. This approach is ideal for conservatory windows reachable from the ground or up to the second floor using ladders, ensuring every glass surface is left spotless and gleaming.

Extra care

Interior conservatory windows cleaning

Our interior conservatory window cleaning service offers a detailed, hands-on approach. Using the traditional squeegee method and effective detergents, we remove dirt, stains, and fingerprints, leaving your glass pristine.

For higher or harder-to-reach areas, our professionals use ladders to reach windows up to 2.6 meters - covering the typical UK ceiling height. Each window is carefully cleaned by hand, ensuring a flawless, streak-free finish that brightens up your conservatory interior.

Efficient process

What can you expect from our conservatory window cleaning?

The magic happens in only three steps!

1. Arriving prepared

The technician will park their fully-equipped van within 30 metres of your home and then bring in the deionised water tank, along with the extendable water-fed pole.

2. Deep cleaning with pure water

Pure water will be sprayed on the uPVC frames and windows of your conservatory. Afterwards, the conservatory cleaner will gently agitate the dirt build-up with the brush attachment.

3. Finishing touch

A final spritz of deionised water will wash away all the accumulated dirt and make your sun lounge look brand new!

Please note: If your conservatory windows have wooden frames, then only the panes will be washed to prevent damage to the wood.

Frequently asked questions

What is the best way to clean a conservatory?
The best way to clean a conservatory involves professional methods that ensure streak-free results and thorough removal of dirt from both windows and roofs. Our service uses a high-reach, water-fed pole system with purified water for external cleaning, effectively removing dirt, minerals, and chemicals without harsh chemicals. For interior windows, the traditional squeegee and detergent method is used for a detailed, hands-on approach. This combined method ensures all glass surfaces, including hard-to-reach areas, are left spotless and gleaming.
How much does it cost to clean conservatory windows and roof?
The cost to clean conservatory windows and roof depends on factors such as the size and type of your conservatory, its current condition, and whether you require cleaning for one side (external) or both sides (external and internal). Prices are also influenced by membership in the Fantastic Club, which offers discounted rates. For example, cleaning one side start at £74, with club member prices from £44. A precise quote can be obtained by checking prices and availability online, considering the area's dimensions and the appointment time.
How often should you clean your conservatory roof?
The frequency for cleaning your conservatory roof depends on factors like your local environment (e.g., proximity to trees, pollution), weather conditions, and how quickly dirt, moss, or algae accumulate. Generally, an annual professional cleaning is recommended to maintain its appearance and prevent stubborn buildup. However, if you notice significant moss, algae, or heavy dirt, more frequent cleaning might be beneficial to ensure your conservatory remains pristine.
How do you clean the outside of a conservatory roof?
Our professional conservatory window cleaning service uses a high-reach, water-fed pole system to clean conservatory windows and roofs with ease. This system is equipped with a 22-meter carbon fiber pole, ensuring every corner of your conservatory's glass surfaces is thoroughly accessible. Purified water is sprayed on the uPVC frames and windows, and a brush attachment gently agitates the dirt buildup before a final spritz of deionized water washes away all accumulated grime, leaving your sun lounge looking brand new.
How do you remove moss from a conservatory roof?
Removing moss from a conservatory roof is effectively achieved through professional cleaning methods like our water-fed pole system. This method utilizes purified water sprayed under pressure, which effectively dislodges accumulated grime, moss, and algae without the need for harsh detergents. The cleaner gently agitates the dirt buildup with a brush attachment, allowing the deionized water to wash away all the accumulated organic matter, leaving your conservatory roof crystal clear and free from streaks or residue.
How come you don’t use any detergents?
For starters, there is no need. Purified water is enough to dislodge the accumulated grime, moss and algae. On the other hand, if we use detergents, we'll have drainage problem. When those chemicals reach the ground, we’ll just have another mess. And the final reason is that some conservatory roofs have protective coating that might be ruined by cleaning chemicals.
Can I use bleach to clean my conservatory roof?
It is not recommended to use bleach or other strong chemicals to clean your conservatory roof. Our service explicitly states that they do not use any detergents, as purified water alone is sufficient to dislodge grime, moss, and algae. Using chemicals like bleach can have detrimental effects, potentially damaging the protective coating on some conservatory roofs or causing drainage problems by polluting the ground around your garden. Our eco-friendly approach prioritizes safety for your property and the environment.
Do you need scaffolding to clean a conservatory?
No, you typically do not need scaffolding to clean a conservatory, especially with modern professional methods. Our service uses an extended-reach, water-fed pole system equipped with a 22-meter carbon fiber pole, which allows technicians to thoroughly access every corner of your conservatory's glass surfaces, including the roof, from the ground. This significantly reduces risk to your property and ensures a safe, efficient clean without the need for ladders or scaffolding for external cleaning.
My conservatory has gutters, can you clean them as well?
This service covers conservatory window cleaning only. However, you can book gutter cleaning as a separate service which is done with specialised equipment.
Can the technician clean the window panes from the inside?
Yes, he can do that for you using a squeegee and a bucket of filtered water.
Do you provide conservatory valeting?
No, currently we do not provide such a service.
Do you clean solar panels, tiled and polycarbonate roofs?
No, right now we do not carry out such cleaning procedures.
Can you clean my fabric blinds?
We can arrange this but please keep in mind that it is a separate service. However, you can combine it with your conservatory cleaning.
