Floor joist repairs in Cookstown
If a plumber or electrician has recently had the boards up at your Cookstown home, the joists they worked around are worth a look. Deep notches and holes in the wrong place weaken joists quickly, and sistering them is usually a short, tidy job.

How do local ground conditions affect floor joist repairs in Cookstown?
Cookstown is in County Tyrone and takes in postcode districts BT80. About 11,000 people live there. We also take enquiries from nearby Magherafelt (9 miles), Dungannon (10 miles) and Portadown (19 miles).
Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause.

What happens when we carry out floor joist repairs in Cookstown?
Photos and a call
Send photos of the dip or soft area, the outside wall at ground level and any air bricks. A short call about when it started, and any recent plumbing or heating work, tells us whether the problem is local or widespread.
Written quote
You get a no-obligation written quote listing which joists are sistered, spliced or replaced and any sleeper wall or ventilation work. It becomes a fixed price in writing once the repair is specified.
Repair the structure
Boards are lifted and numbered if they are going back, and rotten timber is cut out. New treated timber is fixed and checked with a level before strutting, hangers and any restraint straps go in.

Which repair method suits a home in Cookstown?
Splicing ends and fitting hangers
Where only the end has rotted, it is cut back to sound timber and a new piece is fixed alongside, bearing on the wall or on a new joist hanger. Missing or under-nailed hangers elsewhere are replaced at the same time. The damp in the wall must be fixed too.
Best for: Rotten joist ends in damp solid walls
Replacing joists and boards
When rot or woodworm runs through most of a floor, it is usually cheaper to replace the joists, strutting and boards together. Where joists run parallel to an outside wall, restraint straps tie the new floor back to it so the wall keeps its lateral support.
Best for: Widespread rot, or a whole floor that has dropped
Rules for floor joist repairs in Northern Ireland
In Northern Ireland, minor repairs usually need no approval, but structural work comes under the Building Regulations (Northern Ireland) 2012 and council building control. There is no Party Wall Act in Northern Ireland.
Floor joist repairs in Cookstown: questions and answers
What is the price of floor joist repairs in Cookstown?
Guide prices for floor joist repairs in Cookstown start from about £220 per joist, 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.
Do you carry out floor joist repairs in Cookstown?
Yes, Cookstown is covered, along with postcode districts BT80. We also cover nearby Magherafelt and Dungannon.
Does the ground around Cookstown cause cracking?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Only an investigation can say why a particular building has moved.
Is a sagging floor dangerous?
A gentle, long-standing sag is usually not dangerous, and many older floors have moved slightly over a century. A sag that is getting worse, soft boards or a floor dropping near a wall needs checking soon, because rotten joist ends can lose their bearing.
Do I need building control for floor joist repairs?
Usually not for like-for-like repairs to a few joists, but replacing a whole floor structure can be building work. In Scotland that generally needs a building warrant, and in Northern Ireland council building control applies. We deal with building control where the work needs it.
