Dean paints metal gates, railings and steel garage doors in Hunsbury Meadows, NN4, roughly 2.2 miles south-west of Northampton town centre. Metalwork on this modern estate is mostly up-and-over garage doors and side gates on the late-1990s houses, plus any railings on the canal-side Pineham Lock frontages.
Garage doors first, railings second
Older parts of Northampton have Victorian cast-iron railings and ornate front gates. Hunsbury Meadows does not. Its metalwork is modern and practical: steel up-and-over garage doors on the late-1990s detached houses, some of which have double garages with two doors side by side, metal side gates, and any railings along the canal-side frontages in the Pineham Lock streets built from 2012 to 2015. That is a different set of jobs, with different primers, and it is mostly about steel rather than iron.
Steel garage doors at 25 years old

A garage door on a house sold new between 1996 and 2001 has had a quarter of a century of sun and rain. Factory coatings on steel doors fade and go chalky, and rust starts along the bottom edge where water sits and at any scrape or dent from cars and bikes. On a double garage, two doors side by side make any difference in colour or wear obvious, so we usually paint both together.
The work runs in this order:
- Wash off dirt and chalky residue and degrease the panels.
- Take rust spots back to bright metal with abrasive pads and a wire brush.
- Prime bare steel with a rust-inhibiting primer, and key the sound factory finish so new paint can grip it.
- Finish in two coats of a metal or exterior gloss or satin, keeping paint off springs, runners and the locking mechanism.
If a garage door is timber rather than steel, it is treated as joinery instead, with the same care given to the bottom rail where water collects. The wider guidance on metals and primers sits on our main metal gate and railing painting page.
Gates and railings in a damp corridor
The canal and open meadow along the western edge of the estate keep the air damper than on the streets further in, and Wootton Brook with its balancing lakes runs past the south. Steel near water that has lost its coating rusts quickly, and the rust creeps under sound paint from every chip. So side gates and railings on the canal-facing Pineham Lock roads, Towpath Avenue and Lockgate Road among them, are checked closely at the hinges, latches and base of the posts, where water lingers.
Newer gates and railings are often galvanised. Ordinary metal paint does not stick to fresh zinc and peels off in sheets, so galvanised steel gets a primer made for it after cleaning. Where it is hard to tell whether a gate is galvanised or painted mild steel, a small test patch settles it before the full job.
Railings on the Narrowboat Lane flats and maisonettes may be shared parts of the building. If they belong to the freeholder or a management company, the work needs their agreement, and we can quote them directly.
Before we start on site

Metal painting needs dry weather, with the steel above the dew point, so early mornings by the canal can push the start time back. Gates are sheeted underneath because the block-paved drives on the late-1990s streets stain easily. Riverstone Way’s pavement parking means an early arrival or space on your drive. There is no conservation area here, so you can pick any colour; matching the garage door to the front door or window frames is a common choice.
