Who We Are
Local Roots,
Spotless Results.
Grime Scene Investigators is a family-run window cleaning business based in Maidenhead, Berkshire. We've been making windows shine across the local area for years — and we're not done yet.
How It Started
We started out with a ladder, a bucket, and a straightforward idea: clean windows properly, show up when you say you will, and charge a fair price. That hasn't changed. What has changed is the reach — we now cover Maidenhead, Cookham, Taplow, Bray, Hurley, and the surrounding villages, and we've built up a loyal customer base who trust us to turn up every time.
We didn't grow by cutting corners or undercutting on quality. We grew because customers called back, and because they told their neighbours. That kind of growth is slow — and it's exactly the kind we want.
"The price we quote is the price you pay. And you don't pay a penny until the job is done to your satisfaction."
How We Work
Every job runs the same way. We assess, we quote in writing, we arrive when we say we will, and we don't leave until the windows are clean and you're happy. Nothing is marked complete until you've seen it and agreed. That's not a policy — it's just how honest work gets done.
We're fully insured, and we offer 25% off your first clean because we think that matters. If you'd like to know more about what we cover or how we price a job, just give us a call — we're always happy to talk it through before you commit to anything.
Reliable
We arrive when we say. We call before every visit. Showing up on time is the floor, not the achievement.
Don't Pay Until Done
Nothing leaves your account until the job is complete and you're satisfied. No exceptions.
