Should an Overgrown Boundary Be Cleared Before New Fencing Is Installed?

Yes. Fencing along an overgrown boundary is slow, blind, and frequently ends with the fence in the wrong place.

The Short Answer

Clear first, then fence. You cannot set a line you cannot see, working through growth is far slower, and clearing regularly reveals things that change the job.

Doing both as one arrangement means one set-up and one waste removal, which is usually cheaper than two separate visits.

What Clearing Reveals

The boundary line is the one that matters. Once years of growth comes off, the fence line frequently turns out not to be where either neighbour assumed. It is far better to discover that with an open boundary and time to talk than after posts are concreted in — moving a fence afterwards is expensive, and moving it after a disagreement is worse.

The Neighbour Conversation

Ten minutes looking at a cleared boundary together saves more money than any other conversation in fencing.

What About the Hedge?

Where the overgrown boundary is a hedge rather than brambles, there is a decision to make first: keep and reduce it, or remove it and fence. Keeping it means the fence goes in front or behind and the hedge continues to need cutting — with the fence now making one face harder to reach. Removing it gives a clean line but loses the screening and the wildlife value. Either is legitimate, but it is a decision to make before the fencer arrives, not while they are standing there.

FAQs

Clearing Before Fencing in Keynsham — FAQs

Should an overgrown boundary be cleared before fencing?

Yes. You cannot set a line you cannot see, working through growth is far slower, and clearing regularly reveals things that change the job.

What does clearing usually reveal?

The actual boundary line, the condition of any existing fence, tree roots that affect post positions, level differences between gardens, and sometimes dumped material.

What if the boundary is not where we thought?

Far better to find out with an open boundary and time to talk than after posts are concreted in. Check the title plan and agree it with the neighbour before anything is fixed.

Is it cheaper to combine clearance and fencing?

Usually. One set-up, one waste removal, and post spoil leaves with the clearance rather than needing its own trip.

What if the boundary is a hedge?

Decide first whether to keep and reduce it or remove it and fence. Keeping it means the fence goes in front or behind and one hedge face becomes harder to reach.

Do you need access to the neighbour's side?

Usually at some stage. It is worth arranging when you have the boundary conversation rather than on the day.

Can the old fence come out at the same time?

Yes, and it should — it leaves with the clearance waste rather than as a separate job.

What order should the whole job go in?

Clear the boundary, deal with trees and hedges, agree the line, remove the old fence, install the new one, then remove all the waste together.
