C-Thru External Cleaning Solutions Marks Over 20 Years of Window and Exterior Cleaning Across Leeds and West Yorkshire
Family-run firm led by founder Phillip Scott now cleans around 2,000 homes and businesses a month across five West Yorkshire towns, backed by a 5-star Google rating, a DBS-checked team and £5 million in public liability cover.
LEEDS, England — July 11, 2026 — C-Thru External Cleaning Solutions, the family-run window and exterior cleaning company led by director and founder Phillip Scott, has passed more than 20 years of service across Leeds and West Yorkshire. The company now cleans around 2,000 residential and commercial properties every month across Leeds, Bradford, Wakefield, Huddersfield and Halifax, and holds a 5-star rating from customers on Google.
For a business that started with one man, a ladder and a bucket, two decades is a long way to travel. What began as a modest local window-cleaning round in Leeds has grown into one of West Yorkshire’s established exterior cleaning operations, serving thousands of households and businesses each year. The milestone arrives at a point when the company is busier than it has ever been, cleaning roughly 2,000 properties a month and adding new domestic and commercial customers across the region.
From window cleaning to full exterior care
The service list has widened considerably since the early days. C-Thru began with residential window cleaning and now covers commercial window cleaning for offices, shops and retail units, along with gutter clearing, conservatory cleaning, driveway and patio washing, and fascia, soffit and uPVC cleaning. Jet washing and pressure washing round out the range. Customers can book a one-off clean or a regular weekly, fortnightly or monthly visit, with no contract required — a flexibility the company credits with helping it keep customers over years rather than single jobs.
Geography has been central to that growth. From its base at Queensthorpe Close in Leeds, C-Thru covers the full spread of LS postcodes — from the city centre and Headingley through to Horsforth, Morley, Pudsey and Otley — as well as Bradford, Wakefield, Huddersfield and Halifax. Staying local has let the team hold appointment times and respond quickly, something national chains often struggle to match in the smaller towns across West Yorkshire.
Twenty years built on the same few habits
Ask Phillip Scott what has kept the business running for two decades and the answer has less to do with equipment than with habits. Every member of the team is DBS-checked, uniformed and trained, and each turns up in a signed van. Every job is covered by £5 million in public liability insurance. And customers are asked to pay only after the work is finished and they are satisfied with it — a policy the company has held since the beginning. New customers are offered 10% off their first clean, with prices starting from £12, and the firm’s 5-star Google rating reflects a customer base that tends to stay rather than shop around.
The way the work gets done has changed far more than the customers have. In the early years, almost everything was done with a traditional ladder. Today, C-Thru uses pure water-fed pole systems for upper-storey glass, reaching first- and second-floor windows from the ground. The method leaves glass streak-free as it dries, relies on purified water rather than detergents, and keeps the team off ladders for much of the working day — a meaningful safety gain across 20 years of daily cleaning at height. Where a traditional ladder and cloth still suit a job better, the team uses them.
“When I started out, it was me, a ladder and a bucket,” said Phillip Scott, director and founder of C-Thru External Cleaning Solutions. “Twenty years on, we’re cleaning around 2,000 properties a month, and the thing I’m proudest of hasn’t changed: people across Leeds and West Yorkshire still trust us with their homes and their businesses. That trust is the whole business. We’ve never asked for payment until the customer is happy, and we’re not about to start now.”
Homes, landlords and businesses across the region
That customer base runs well beyond homeowners. C-Thru works with landlords, letting agents, small offices, city-centre retail units and larger commercial buildings, fitting commercial cleans around early mornings and weekends to avoid disrupting trade. For many domestic customers the relationship stretches to years of regular visits; for others, the company handles one-off cleans tied to moving house, a post-build tidy-up or a seasonal refresh. It is a mix the company says has kept the work steady through changing economic conditions, because clean windows and clear gutters are needed in good years and lean ones alike.
The commercial side has grown alongside the domestic round. Shopfronts in Morley, offices in Leeds city centre and retail units across the region are now part of a regular rota, with the same uniformed, insured team handling both a two-bedroom terrace and a multi-storey office block. Keeping both sides of the business under one roof, the company says, is part of why customers refer it on.
“The plan for the next 20 years is the same as the last 20,” Scott added. “Stay local, turn up when we say we will, and leave every window looking the way it should. If we keep doing that, the rest tends to take care of itself.”
Two decades of trading have also given the company a close read on how demand moves through the year. Spring brings a rush of window and conservatory cleaning as households open up after winter. Autumn shifts the emphasis to gutter clearing, before leaves and heavy rain cause blockages and damp. Driveway and patio washing tends to cluster around late spring and the run-up to summer, and one-off cleans spike whenever the local property market is active and sellers want their homes looking their best for viewings. Handling the full range of exterior work under one team, the company says, means a customer who calls about a blocked gutter in November is often the same one who books a window round the following spring — part of why so much of the business now comes from repeat custom and word of mouth.
The company has no plans to expand beyond West Yorkshire, preferring to deepen its coverage across the towns it already serves. As it enters its third decade, C-Thru says its focus stays on the day-to-day standard that built the business over the previous two: reliable, insured, fairly priced exterior cleaning close to home.
