From Green to Gleaming: How We Restore Algae-Covered Fascias in Cambridge

As the sun begins to shine brighter over Cambridge from June through September, many homeowners start to notice things they might have missed during the darker winter months. You step out into the garden for a BBQ, look up at your roofline, and realise that what used to be crisp, white uPVC has turned a disappointing shade of “swamp green.”

If your home’s exterior is looking a little worse for wear, you aren’t alone. Algae, lichen, and general environmental grime love to call your roofline home. At AE Window Cleaning Service Ltd, we specialise in fascia and soffit cleaning in Cambridge, transforming tired, green exteriors back to their original “gleaming” state.

In this guide, we’ll walk you through why this happens, why it matters, and how our professional restoration process works.

Why Do My Fascias and Soffits Turn Green?

It’s a common question we get while out on the job: “Why is it only my house that looks green?” The truth is, it happens to almost everyone eventually.

Fascias (the long, straight boards that run along the lower edge of the roof) and soffits (the boards tucked underneath them) are constantly exposed to the British elements. Because they are often shaded by the roof’s overhang, they stay damp for longer periods after it rains.

This moisture, combined with organic matter like pollen and dust, creates the perfect breeding ground for:

• Green Algae: The most common culprit, especially on North-facing or shaded sides of the property.
• Black Mould: Often found in areas with poor ventilation or near leaky gutters.
• Lichen: Harder, crusty spots that can be more difficult to remove if left too long.

When the summer sun hits these areas, the green becomes even more prominent, making the whole house look neglected, even if your windows are spotless!

The Before and After Impact: More Than Just Aesthetics

You might think that fascia and soffit cleaning in Cambridge is purely about “curb appeal,” but there are several practical reasons to keep these areas clean:

1. Preventing Permanent Staining: uPVC is durable, but it is also slightly porous. If algae and grime are left to bake in the summer sun for years, they can actually “sun-tan” the plastic, leading to permanent yellowing or grey staining that even a deep clean can’t fully reverse.
2. Identifying Gutter Issues: Often, a heavy concentration of green or black grime in one specific spot on your fascia is a “tell-tale” sign of a leaking gutter or a blockage. By cleaning the area, we can often spot maintenance issues before they cause damp problems inside your home.
3. Property Value: If you are looking to sell your home this summer, first impressions are everything. A potential buyer looking at a house with green rooflines might worry about the overall maintenance of the property.
4. Spider Control: Spiders love the nooks and crannies of dirty soffits. Regular cleaning removes the webs and the insects they feed on, keeping your window frames cleaner for longer.

How We Restore Your Fascias: The AE Professional Process

Cleaning high-level uPVC isn’t just about splashing some water around. To get that “like-new” finish, we follow a systematic professional process.

1. Assessment and Preparation

We begin by assessing the height and condition of the boards. Most modern homes in Cambridge can be safely cleaned from the ground using our water-fed pole technology. We first wet the surfaces down to loosen the initial layer of dust.

2. Specialized Cleaning Solutions

Water alone often isn’t enough to break the bond between the algae and the uPVC. We use eco-friendly, specialized uPVC cleaning solutions or “Traffic Film Removers” (TFR). These are applied carefully to break down the organic growth without damaging your garden plants or the integrity of the plastic.

3. Agitation and Scrubbing

Using soft-bristled, flocked brushes, we manually agitate the grime. We pay special attention to the “grooves” in the soffits and the joints where the fascia boards meet, as these are hotspots for dirt accumulation.

4. Pure Water Rinse

Once the cleaning solution has done its work, we rinse everything down with RO-purified water. Because this water is stripped of minerals, it doesn’t leave any white spots or streaks as it dries. You can learn more about the science of pure water here.

Why Choose Professional Cleaning Over DIY?

It can be tempting to grab a ladder and a bucket of soapy water on a Saturday afternoon, but there are several reasons why homeowners in Cambridge prefer to call us in:

• Safety First: Fascias are, by definition, at the highest point of your ground or first floor. Working at height on a ladder while trying to scrub and hold a bucket is a leading cause of domestic accidents. Our telescopic poles allow us to work safely from the ground.
• The Right Equipment: To get into the deep corners of a soffit, you need specific brush angles. Our equipment is designed specifically for the architecture of UK homes.
• No Mess, No Stress: We ensure that the dirty run-off doesn’t leave streaks on your windows. In fact, many of our customers choose to bundle their fascia cleaning with a full domestic window cleaning service for a total home refresh.
• Preventing Damage: Pressure washers can be too powerful for uPVC, often blowing water behind the boards into your roof space or cracking the plastic. Our “soft wash” approach is much safer.

Completing the Summer Look

While we are up there looking at your fascias, it is the perfect time to consider the rest of your roofline and exterior. Summer is the ideal window for total maintenance before the autumn leaves begin to fall.

Gutter Clearing

If your fascias are green, there is a high chance your gutters are full of the same organic matter. We use the SkyVac system to clear out moss and debris, ensuring your home is protected from water damage.

Solar Panel Cleaning

With the sun at its peak in July and August, you want your solar panels to be as efficient as possible. Just like fascias, solar panels collect dust and pollen which can drop their energy output significantly. We offer a dedicated solar panel cleaning service to help you maximize your savings.

Frequently Asked Questions

How often should I have my fascias cleaned? For most homes in Cambridge, a deep clean once a year (usually in late spring or early summer) is enough to keep them looking white. If your home is surrounded by large trees, you might require a bi-annual refresh.

Will the cleaning solution hurt my roses or flower beds? No. We are very conscious of your landscaping. We pre-wet any surrounding greenery and use diluted, biodegradable solutions that are safe for the environment.

Do you need to use my outdoor tap? Our vans are fully equipped with vehicle-mounted tanks of purified water, so we can usually carry out the work even if you aren’t home or don’t have an external tap available.
