Home / Locations / Hertfordshire / Car valeting
Hertfordshire is a county of planned towns and old ones, and its cars get dirty in two different ways: the garden cities and the New Towns park under trees, the market towns park in the street, and all of them commute down the A1(M) or the A10 into the salt and the spray. A valet, outside and inside in one visit, is the clean most households here actually want, and Yikes brings it to the drive or the kerb through vetted local washers from the Yikes Network. Stevenage has its own page. This one covers the towns around it, from Hitchin and Letchworth in the north to St Albans and Hertford in the south.

What is included
Town by town
A market town since at least the seventh century, Hitchin parks in its streets: the terraces off Walsworth Road and Bearton Road, the Victorian villas by the Priory, the closes out at Westmill. The cars carry chalk from the Chiltern lanes, the River Hiz's damp in winter and the market's Saturday dust. A valet at the kerb in your own space, with the inside done so the lavender fields' summer and the school run's crumbs both go.
The first garden city was laid out from 1903 with wide verges and trees on every road, and the cars of Letchworth live under them: lime and sycamore sap in June, leaf stain in November. Baldock adds the A1(M)'s spray. The Deluxe Inside & Out lifts the sap film properly, which a rinse never does, and the drives of Letchworth and Baldock are wide enough for two cars on one booking.
The second garden city, founded in 1920, is the greenest town in the county and the one where a parked car gets dirtiest fastest: sap, pollen, bird mess and the shade that keeps it all damp. Hatfield's cars do the A1(M) and the university run. A Deluxe every four to six weeks in WGC and Hatfield keeps the paint from dulling under the trees; the Essential between keeps the cabin civil.
The county town sits on the Lea and its cars carry river damp, the A10's film and, in the terraces of Bengeo and the closes of Sele, a winter of salt. Ware is the same river, further down. The inside half of the valet matters here, with the damp lifted from the carpets and the inside glass done for the mornings when the river mist sits on the town.
The cathedral city and its commuter neighbour run the newest cars in the county, parked on drives in Marshalswick, Fleetville and the Harpenden avenues, and driven to the station and the M1. The dirt is motorway film and tree sap, and the valet is a habit rather than a rescue: Deluxe Inside & Out monthly, Deluxe Exterior between for a car that mostly commutes.
Knebworth, Datchworth, Codicote, Kimpton, Whitwell and the villages between the A1(M) and the A602 are lane country: mud in the arches, hedge scratches, sap under the oaks, and a dog in the boot. The valet comes to the drive with its own water, which matters in a village where the outside tap is at the back of the house.
Across the county
The county council's winter service starts on 1 October and its crews are on standby around the clock until the end of April, treating about 1,500 miles of priority roads whenever the surface is forecast to fall to half a degree: every A and B road first, then bus routes and one road into each village of fifty houses or more, then the steep roads and the routes to care homes and libraries. Which is to say that nearly every road a Hertfordshire car uses gets salted, and the salt sits on the paint and walks into the cabin for six months. A valet every four to six weeks through the season is the one habit that keeps a car looking new, and the clocks went back on 25 October, so a window that starts by 2pm finishes in the light.
Booking is the same in every town: postcode in, the page confirms a Network washer covers it, pick the Deluxe Inside & Out or the Essential and a two hour window, and pay. Twice a year, after the gritters stop in April and before they start in October, the Super Valet with its wax and interior restoration is the right upgrade; for a car that has been neglected for a year, the Deep Clean comes first.
