How Much Does It Cost to Replace an Old Lawn With Turf in Keynsham?

Replacing a lawn means lifting the old one first. That is the part people do not price, and it is a genuine part of the job.

The Short Answer

Replacement is quoted as lifting and disposing of the old lawn, preparing the ground beneath it, and laying new turf. The lifting and disposal is a real cost — old turf is heavy and there is a lot of it.

We do not publish a fixed price list for turfing, because ground preparation varies far more between gardens than the turf itself does. What we can do is explain what changes the number.

Why the Old Lawn Has to Come Up

Turf cannot be laid over an existing lawn. The old grass and thatch beneath prevent the new turf rooting into soil, the old weeds grow up through it, and the level rises by the thickness of both layers — which puts the lawn proud of paths and, in the worst cases, above the damp proof course. It is not a shortcut, it is a failed lawn.

What the Job Involves

Before You Replace — Would Renovation Do?

ProblemReplace, or renovate?
Moss and thatchRenovate — scarify, aerate, feed, overseed
Thin and patchyRenovate first, usually
Weedy but levelRenovate
Uneven and bumpyReplace — levels need the turf lifting
WaterloggedNeither, until drainage is addressed
Compacted and deadReplace
Wrong shape or positionReplace
Deep shade under treesNeither — reconsider the lawn

Renovation costs considerably less and is often enough. A lawn that is thin, mossy and unloved can be transformed by scarifying, aerating, feeding and overseeding over a season. What renovation cannot fix is levels, drainage, or a lawn that is genuinely dead — and those are the reasons to replace.

What Is Usually Found Underneath

Every old lawn we lift explains itself. The bare patch was over a path, the boggy corner has no drainage, and the moss was compaction all along.

Fix the Cause

This is the point of replacing rather than patching. If the old lawn failed because of compaction, poor drainage, thin soil or deep shade, laying new turf over the same problem produces the same lawn in three years. The moment the old turf is off is the only opportunity to address any of it — and it costs far less now than it will when the new lawn is down.

FAQs

Replacing an Old Lawn in Keynsham — FAQs

How much does it cost to replace an old lawn with turf?

It is quoted as lifting and disposing of the old lawn, preparing the ground beneath, and laying new turf. The lifting and disposal is a real part of the cost.

Can new turf be laid over an old lawn?

No. The new turf cannot root into soil through old grass and thatch, old weeds grow through, and the level rises by the thickness of both layers.

Would renovating be cheaper than replacing?

Considerably, and it is often enough. Scarifying, aerating, feeding and overseeding transforms a thin, mossy lawn — but it cannot fix levels, drainage or a dead lawn.

When is replacement the right choice?

When the lawn is uneven and needs levelling, when it is compacted and dead, when the shape or position is wrong, or when drainage work is needed underneath.

What is usually found under an old lawn?

Compaction almost always, often thin soil over rubble, sometimes old paths that explain the dry patches, and poor drainage that explains the wet ones.

Will the new lawn last longer?

Only if the cause of the old one's failure is addressed while the turf is off. Laying new turf over the same problem produces the same lawn in three years.

Do you take the old turf away?

Yes. It is heavy, bulky waste and removal is part of the job.

Is it worth doing if the garden is deeply shaded?

Often not. Grass struggles in deep shade whatever you lay, and a shade planting or bark area may be a better answer.
