Matt MacDonald also just cleaned my windows, i live on Chestnut Grove. I would recommend him very highly. 
He's professional, super polite, friendly and efficient and happy to clean internally, as well.
I very much think his ethos is ‘the customer is King, or Queen ’. Not something i find too often in the UK. 
His number has changed from the earlier posts :07519 957963

LOVELY CHAP AND GOOD RATES!!

I used Matt McDonald last month, he was better value than anyone of the other quotes I got, he cleaned the windows from inside and out in an hour and he comes back every three months to clean the outsides of the front windows for £10. He was friendly, tidy and nice to have about the house. Will definitely use him again. Number is 07972062068.

I've used Matt based on the recommendations here and Streetlife, and agree he's very good, thorough, kind and reasonable. I suggest you give him a call to describe the work or have him pop by to give you an estimate. He told me he's not the cheapest as he has all the proper insurances, his own truck, the water mechanism, etc but he's not the most expensive either. And he lives in SW and I like supporting local if its good value.

Hi! We live in Sw12 Dinsmore road. A guy called Jimmy regularly cleans our windows. He charges 10£ for front windows (5) and 25£ when he cleans the kitchen externsion and back windows as well. Guy just comes once per month early in the morning and does his job pretty well.
If you are interested I can ask him if he also comes to your road.
let me know

Hi

Just looking at these postings as we need a window cleaner. Can you tell me how much Matt charges please?

Many thanks!

I can also recommend Matt.

He cleaned all of our windows inside and out for the first time last week. Very reasonably priced and did a great job.

He uses his own purified water so no streaks.

He is also very polite.

Hello,

Recently used Matt Macdonald - 07972 062 068. Really good job and did the inside as well.

Does anyone know a reliable window-cleaner in the Balham area (we're in SW17, just off Boundaries Road)?
