Jet Washing in Colindale, NW9
Jet washing in Colindale, NW9, in Barnet: new apartment blocks with concierge and service lifts, plus 1930s semis behind, so the surfaces here run to in-situ concrete, tarmac aprons, precast stair treads and steel balustrades. The job booked most often is walkways, bin stores and car park bays cleaned with hot water and a degreaser, and the local failure we correct most is surface-water drains that must be guarded before a single trigger is pulled.

Not when the pressure matches the material. Locally that means in-situ concrete, and the risk we guard against is surface-water drains that must be guarded before a single trigger is pulled on this side of Barnet, with a median age of 32 in this neighbourhood. We test a hidden metre first and drop to soft washing, under 40 bar, on render, brick and fragile stone on NW9 jobs, with Barnet parking rules in play.
Yes, and it is included. Kiln-dried sand is brushed and vibrated into the joints on the day in this 80% flats neighbourhood, with Barnet parking rules in play, then topped up again once the surface dries. Cleaning block paving without re-sanding leaves the blocks free to move and sink on this side of Barnet. Near The former Hendon Aerodrome and Colindale Gardens that usually means an earlier start so the van can be unloaded once.
Into our tank. Every gully gets a drain guard before we start, silt is vacuumed up and removed under our waste carrier licence in Colindale, with The former Hendon Aerodrome and Colindale Gardens a few streets away, and detergent never reaches a Barnet highway drain. That is a legal requirement, not an extra.
Every new block requires booked goods lifts and loading bays; estate roads are gated on NW9 jobs. London Borough of Barnet suspensions and visitor permits are arranged and paid for by us and sit inside the quoted price on the Colindale rounds, with 35% of NW9 homes being privately rented. Where the only route to a back garden is through the house, we lay hose matting and wear boot covers across NW9, with 33% social-rented stock nearby.
Black spot lichen, yes — killed at the root with a biocide, fading over two to three weeks rather than on the day around Colindale (Northern), with 32% owner-occupation locally. Old oil soaked into porous concrete lightens with hot water and a poultice but rarely disappears in Colindale, with 33% social-rented stock nearby. We say so before you book.
Yes. Every area in Barnet has its own page on Barnet bookings, and we cross borough boundaries constantly. If your address sits on the edge of NW9, book the nearest page and we will confirm the same fixed price in this 80% flats neighbourhood, with 32% owner-occupation locally.
