Cleaning windows in N21, honestly.
Written window cleaner to window cleaner. This is the ground truth the lead sites have never worked.
The glass. Mostly pre-war terraces with conversions stacked over them around Grange Park: two windows up, one bay down, and a front door straight onto the street. One street done well fills the street: watching the cleaner work is still how half of terraced Britain picks one. A quiet stream of first cleans and gutter jobs flows from the 327 completions logged here in a year, underneath the regular round.
The parking. Controlled parking rules most streets here, so the van's spot is the first decision of every job. Learn the zone hours: many go free after half five, and the smart rounds shift their tightest streets to the edges of the day. Hard water sets the rules in this region: resin and membranes work hard, spotting punishes shortcuts, and the cleaner whose glass dries clear keeps the street.
The round. The round in N21 works around Winchmore Hill, Grange Park and Highlands Village. Around 9,201 households live here, and the ones who take a window cleaner keep them — 4-weekly, year round, years on end. That's not a lead list — that's a round, built once and kept.
| Job | Typical price |
|---|---|
| 4-weekly round clean (3-bed) | £28–£36 |
| Conservatory windows add-on | £22–£39 |
| Gutter clear | £100–£170 |
| Full house, gutters, fascias & soffits | £280–£420+ |
| First clean / restoration | £56–£84 |
| Local going rates from our regional price model. The N21 holder sets their own prices — we never touch the money. | |
What owning N21 is actually worth
Put it the way you'd put it on the doorstep: one kept house pays for the page, near enough to the pound, every single year. And unlike a lead site, the second house doesn't cost you a penny more.
