Questions from Harpenden customers
How much extra is a coloured garage door?
Preferred colours such as anthracite grey often cost little or nothing extra; RAL colours to order usually add to the price. A coloured single door is typically around £2,095–£2,995 supplied and fitted.
Can I paint my sectional door later?
Repainting a factory-finished door can affect the warranty and is rarely as durable. It is better to order the colour you want.
Which parts of Harpenden do you cover?
We cover Harpenden across postcode districts AL3, AL5, along with nearby St Albans, Hemel Hempstead and Welwyn Garden City. Dates are agreed when you book.
Will the local district or borough council need to approve my new garage door?
Usually not. Replacing a garage door, including with an electric sectional door, does not normally need planning permission in England unless the house is listed, in a conservation area or Article 4 area, or has planning conditions affecting the garage. If in doubt, ask the local district or borough council before ordering.
