Subsidence repairs in Portadown

Subsidence in Portadown, as anywhere in County Armagh, usually comes back to the ground beneath the footings: clay drying out, a drain leaking or roots taking water. Knowing which applies decides whether the repair is a few days of crack work or a longer foundation scheme.

Why does the ground in County Armagh matter for subsidence repairs?

Portadown, County Armagh: about 33,000 residents across postcode districts BT62. Neighbouring towns we cover: Craigavon (3 miles), Banbridge (8 miles) and Armagh (10 miles).

Shrinkable clay is less common in County Armagh than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. Across County Armagh, most homes are Georgian houses in Armagh, brick terraces in Portadown and Lurgan, and post-war estates.

Repair options we may recommend

Foundation strengthening

Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.

Best for: Ongoing movement where removing the cause has not worked

Crack stitching and making good

Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.

Best for: Category 1 to 3 cracking in walls that are otherwise sound

What to expect when we carry out subsidence repairs

  1. Find the cause

    An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.

  2. Written quote

    We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.

  3. Repairs and making good

    Cracks are stitched and repointed outside, plaster is renewed along the crack lines inside, and sticking doors are eased. Where the work needs it, we deal with building control and hand over the paperwork.

Rules for subsidence repairs in Northern Ireland

In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.

Your subsidence repairs questions

How much should I budget for subsidence repairs in Portadown?

Guide prices for subsidence repairs in Portadown start from about £2,200 per property, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Portadown?

Yes, Portadown is covered, along with postcode districts BT62. We also cover nearby Craigavon and Banbridge.

Why do houses in County Armagh crack?

County Armagh has glacial drumlin till over older rock, with soft ground and peat near Lough Neagh. Only an investigation can say why a particular building has moved.

Does subsidence always need underpinning?

No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.

Should I cut down the tree near my house?

Not without advice, because felling a mature tree on clay can make things worse. As the roots stop drawing water, the clay swells and can lift the foundations, which is called heave. Pruning or staged removal may be advised instead. Check whether the tree is protected.
