Common reasons for replacement bollards in Thornhill
What replacement bollards usually sort out in Thornhill:
- Crushed sockets and failed telescopic cassettes
- Single missing posts in an otherwise sound line
- Posts bent, sheared or broken by vehicle impacts
Before we dig in Thornhill
Before digging near the kerb in Thornhill we establish who owns the ground: adopted footways are Cardiff Council's responsibility, trunk roads the Welsh Government's, and everything else belongs to the site owner.
Bollards on private land often don't need planning permission, but it depends on the council's view, the height and the location; in a conservation area, next to a listed building or under an Article 4 direction, ask the local planning authority (Cardiff Council) first — we flag this at survey.
Upgrades to rated products usually need a completely new, larger foundation. Reinstatement matches the surrounding surface, though weathered paving and older tarmac may leave a visible patch.
- Upgrades to rated products must use the manufacturer's tested foundation, specified with your security adviser.
- On public highway, the highway authority may need to approve the replacement or carry out the work itself.
What happens on site
Survey and match
At the free site survey we measure the existing bollards, photograph the line and check the foundations. A fixed written quote sets out like-for-like and any upgrade options.
Order the replacement
Matching posts, sockets or castings are ordered, and you see details of any close equivalent before it is confirmed.
Install the new post
The new bollard is set in a fresh foundation, aligned with its neighbours and the surface is reinstated to match.
Options to consider
| Option | Detail |
|---|---|
| Making safe | Removing or capping a dangerous broken stub before the replacement is fitted. |
| Matched finishes | RAL powder coat, stainless grade and finish, or heritage paint schemes matched to the existing line. |
| Like-for-like | Same diameter, height, finish and fixing, so the line looks unchanged. |
Pricing replacement bollards in Thornhill
Our Wales guide prices are a starting point; the survey in Thornhill firms them up. What tends to move them:
- Surface type and reinstatement
- Matching special finishes, castings or discontinued products
- Size and condition of the old foundation
After installation
Treat new posts as part of your routine inspections: check for lean, chips and faded bands. A single impact on a rarely struck post is bad luck; repeated strikes in the same spot point to a layout problem, such as a tight turn or a missing wheel stop, that a stronger bollard alone will not solve.
For damaged or loose posts in Thornhill, repairs and replacements are priced in writing first.
