Oven cleaning along Colney Hatch Lane, N11 and N10, from Friern Barnet to the Muswell Hill end. Seven days, no chemical smell, single ovens from £77.
Colney Hatch Lane is the B550, running from Friern Barnet over the North Circular and up to Muswell Hill. The name is best known for the asylum. The Middlesex County Asylum opened on 17 July 1851, Prince Albert doing the honours, and at its peak it held 2,500 patients behind the longest corridor in Britain, long enough that walking the wards took a visitor more than two hours. It cost £300,000 to build, £240 a bed, the most expensive asylum ever put up.
The hospital is flats now
Renamed Friern Mental Hospital in 1937, then plain Friern Hospital in 1959, it closed in 1993, and Comer Homes took the building and grounds in 1995. The main block is Grade II listed and is now Princess Park Manor, off Royal Drive, standing in 30 acres of private parkland. Conversions of that kind mean a period shell with a modern fit-out, which in practice is an integrated single oven at £77. The oven never moves. Only the racks, shelves, trays and side runners go out to the heated tank in the van.
Uphill in N10 the stock changes
Follow the same road up and the housing switches. Muswell Hill is predominantly Edwardian, put up inside a twenty-year window by the builders Edmondson and Collins between 1896 and 1914, and much of it sits inside a conservation area designated on 1 March 1974 that ranks among the largest in London. The detached houses along the Colney Hatch Lane stretch and Alexandra Park Road are the substantial end of it. Houses that size are where 90cm ranges appear, and a range clean is £114 whether the address reads N10 or N11.

Questions from N11 and N10
Do you work in listed buildings?
Yes. Nothing in the method touches the fabric of a building. The oven is degreased where it stands with non-caustic products, and the caustic side of it stays out in the van.
How do Barnet parking rules affect the visit?
CPZ hours vary zone to zone across Barnet, so the sign on the bay is what we go by. It makes no difference to your price.
Can you clean the hob at the same time?
Yes, £23–28 depending on type. An extractor hood is £28 and a microwave £22 if they go on the same visit.
Will the oven work when you leave?
It is switched on and heat-tested before sign-off, so if something has failed you find out while we are standing there.

What customers tell us
Very satisfied with the service. They were slightly late at first but I got a call from customer service to let me know, and it was all fine. The oven man, as he called himself, arrived and worked very hard for a couple of hours. My oven now looks like it has never been used.
Once again a great job guys, I will see you in a couple of months.
I would certainly recommend this service, very efficient and good value for money. The young man did a great job and even cleaned the kitchen floor. Thank you.
