How much does exterior cleaning cost in Harrow?

Most homes in Harrow should have gutters cleaned at least twice a year, ideally in autumn after leaves fall and in spring. Properties near trees may need quarterly cleaning. Signs you need gutter cleaning include water overflowing during rain, sagging gutters, plants growing from gutters, or damp patches on external walls. Regular cleaning prevents expensive water damage to your property.

Is pressure washing safe for my driveway or patio?

Yes, when done professionally. We adjust water pressure based on your surface type. Block paving, concrete, tarmac, and natural stone all require different pressure settings. Our experienced team knows exactly how to clean each material effectively without causing damage. DIY pressure washing often causes problems because people use too much pressure. We get it right first time.

Will roof cleaning damage my tiles?

No. We use soft washing techniques specifically designed to protect roof tiles while removing moss, algae, and lichen. Unlike high-pressure washing which can crack tiles and force water under them, our method is gentle yet highly effective. We've cleaned thousands of roofs across Harrow without a single tile damaged. Your roof is safe in our hands.

Do I need to be home during the cleaning service?

Not necessarily. For exterior services like gutter cleaning, pressure washing, and window cleaning, you don't need to be present as long as we have access to outdoor taps and the areas being cleaned. We'll take before and after photos and send them with your digital invoice. Many of our regular customers leave us to work while they're out. Our reviews often mention how much they trust us with property access. Just let us know your preference when booking.

What equipment do you use for window cleaning?

We use a pure water fed pole system for most window cleaning jobs. This produces streak-free, spotless results without chemicals. The purified water dries naturally without leaving marks. For interior windows or specific requests, we also use traditional methods with professional-grade squeegees and cleaning solutions. Our equipment reaches up to four storeys high safely from the ground.

How long does roof cleaning take?

A typical residential roof cleaning takes between 4 to 8 hours depending on roof size, pitch, and the level of moss coverage. We work carefully to ensure thorough cleaning without rushing. Most jobs are completed in a single day. We'll give you an accurate timeframe when we quote. The results last for years, making it a worthwhile investment in your property.

Can you clean my gutters if they're very blocked?

Absolutely. Heavily blocked gutters are our specialty. We use industrial vacuum equipment that handles even the worst blockages, including compacted leaves, moss, and debris. We'll also clear downpipes and check the entire gutter system is flowing properly. If we find any damage or issues during cleaning, we'll let you know immediately so you can arrange repairs.

What's the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water to blast away dirt, perfect for hard surfaces like driveways and patios. Soft washing uses lower pressure with specialised cleaning solutions, ideal for delicate surfaces like roofs, render, and painted surfaces. We choose the right method for your specific surface to get excellent results without damage. Sometimes we use both techniques on different areas of the same property.

Do you offer regular maintenance contracts?

Yes. Many of our five star customers book regular window cleaning every 4 to 8 weeks, gutter cleaning twice yearly, or annual pressure washing. Regular maintenance keeps your property looking great and prevents minor issues becoming expensive problems. We offer flexible scheduling and discounted rates for recurring customers. Our Google reviews frequently mention customers who've used us for years. Just ask about setting up a maintenance plan that suits your property and budget.

What Our Patio Cleaning Service in Harrow Covers

Natural Stone and Sandstone Patio Cleaning

Natural stone is porous and needs careful handling. Too much pressure strips the surface and leaves it looking blasted and rough. We use controlled, appropriate pressure for stone surfaces — enough to remove algae, moss, and staining without damaging the material. Natural stone patios across Harrow respond well when the technique is right.

Porcelain and Concrete Flag Cleaning

Porcelain and concrete flags are more robust than natural stone and can handle higher pressure, but they still need the right approach to avoid damage at grout lines and edges. We clean both materials thoroughly and evenly using rotary surface cleaners, which avoid the streaking you get from a direct lance. The result is a uniformly clean surface from edge to edge.

Decking Cleaning Harrow

Timber and composite decking goes green, slippery, and dull with algae growth, often well before it’s actually past its useful life. We clean both materials using appropriate pressure and technique. Composite decking in particular responds well to pressure washing and often looks close to new once the surface algae is removed. We can treat timber decking after cleaning to protect the wood and slow regrowth.

Patio Biocidal Treatment

A clean patio will grow back green within a year if nothing is applied to slow it down. After the main clean, we can apply a biocidal treatment to the surface that kills remaining spores and inhibits regrowth significantly, making for a clean that lasts several years. We offer this as an optional addition and recommend it for any surface in a shaded or north-facing garden. pressure washing services see our full range of exterior surface cleaning.

Step and Path Cleaning

External steps, paths that run through the garden, and side passages get overlooked until they become a safety hazard. We clean these surfaces as part of a wider patio job or as a standalone visit, using the appropriate pressure and technique for each material. Algae on steps is a slip risk that’s straightforward to remove and doesn’t need to be tolerated.
