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.

Window Cleaning Harrow: What Professional Cleaners Do That You Cannot

Home Blog Window Cleaning Harrow: What Professional Cleaners Do That You Cannot

Anyone can clean a window. The trouble is the streaks, the smears, and the bit by the upstairs bedroom that you’ve been avoiding for a year.

We clean windows for homeowners across Harrow, Pinner, Stanmore and North West London every week. This guide covers what professional cleaners actually do differently, and where a DIY clean is perfectly fine.

What Professional Window Cleaners Do That You Probably Can’t

1. Use Purified Water

Tap water contains minerals. When it dries on the glass, the minerals stay behind and leave spots. A purification system removes them, so the water dries clear.

Window Cleaning Warehouse explains how this works, and notes that harder water, including in London, costs more to purify:

2. Reach Without Ladders

A water fed pole lets us clean most windows from the ground. No ladder leaning on your gutters, frames or render, and no one climbing for the sake of a smear.

The HSE has guidance on working at height:

3. Clean the Frames and Sills Too

Dirty frames drip back onto clean glass. Frames and sills are cleaned as standard on every visit.

4. Keep Going in Light Rain

Pure water cleaning works in light rain, so a bit of drizzle doesn’t mean a missed appointment.

5. Come Back on a Schedule

Windows get dirty again. Regular plans keep them clear without you having to think about it.

See our window cleaning service in Harrow.

6. Carry the Right Insurance

Public liability insurance covers accidental damage to your property during the clean. That’s worth checking with anyone who works at your home.

Where DIY Is Fine

Ground floor windows you can reach easily
A quick wipe between professional cleans
Small panes in a downstairs room

Where It’s Worth Calling a Professional

Upstairs windows
Windows over conservatories or extensions
Windows you can’t reach safely
Streaks that keep coming back
Frames and sills that need cleaning too

What to Ask Before You Book

What method do you use?
Do you need a ladder?
Are frames and sills included?
Is the price fixed?
Are you insured?
What happens if there are streaks?

The Bottom Line

A professional clean isn’t about the wipe. It’s the purified water, the reach, the frames and the insurance. If your windows are the ones you can reach, DIY is fine. If they’re not, don’t risk it.

Frequently asked questions

Q1: Why do my windows streak when I clean them myself?

Streaks usually come from tap water minerals, soap residue or a dirty cloth. When tap water dries, the minerals stay behind and leave spots and marks. Professional cleaners use purified water, which has the minerals removed, so it dries clear.

Q2: What is pure water window cleaning?

It’s a method that uses purified water, with the natural minerals filtered out, fed through a pole with a soft brush. The brush loosens the dirt, and the glass is then rinsed with the pure water so it dries without spots. It also means no soap residue is left on the glass.

Q3: Do professional window cleaners use ladders?

Not always. We use a pure water fed pole system that lets us reach most windows from the ground, so no ladders are needed for most properties. That avoids leaning anything on your gutters, frames or render.

Q4: Is it safe to clean my own upstairs windows?

It carries real risk. Ladders are for low risk, short jobs, and the HSE publishes guidance on working at height. If your upstairs windows need a ladder or a lean out of a window, a professional with the right equipment is the safer choice.

Q5: How often should I have my windows cleaned in Harrow?

Many homeowners choose a regular clean every 6 to 8 weeks, and some prefer one off cleans. How often depends on how much dirt, pollen and rain you get, and how clear you like them. We offer discounted regular plans and one off deep cleans.

Q6: Do you clean window frames and sills?

Yes. Frames and sills are cleaned as standard on every visit, as well as the glass. Dirty frames drip back onto clean glass, so cleaning them properly is part of getting a good finish.

Q7: Can windows be cleaned in the rain?

Often, yes. Pure water cleaning works in light rain, because the glass is rinsed with clean water as part of the method. Heavy rain or high winds can make some jobs unsafe, in which case we’ll rearrange.

Q8: Can you clean high windows or upstairs windows?

Yes. Our reach and wash system covers windows up to four floors up. For taller buildings, rope access or a cherry picker can be arranged.

Q9: Are you insured to clean my windows?

Yes. We carry full public liability insurance on every job, which covers accidental damage to your property during the clean.

Q10: What if my windows still have streaks after you leave?

We guarantee our windows will be streak free. If you spot anything you’re not happy with, we’ll come back and put it right.
