Brick arch repairs in Thurso
A dropped keystone over a front door is a familiar sight on older streets, in Thurso and beyond, and it rarely fixes itself. We look at whether the arch bricks are sound and whether the wall either side has moved, then recommend the lighter repair where it will work.

What should you know about the ground under Thurso?
Thurso, Highland and Moray: about 7,500 residents across postcode districts KW14.
Clay shrinkage is less of a concern in Highland and Moray, so other causes such as drains, poor footings or older walls are checked first. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Highland and Moray: stone cottages and town houses, Victorian villas in Inverness and Nairn, and post-war estates.
Methods for brick arch repairs
Lime mortar repairs
On older houses built in soft brick and lime, the arch is rebuilt or repointed in a lime mortar matched to the original. Lime lets moisture escape and moves slightly with the wall, so it protects the bricks rather than forcing damage into them, as hard cement mortar can.
Best for: Pre-1919 houses and soft historic brick
Rebuilding both faces
Where the arch shows inside as well as outside, or a rotten timber behind it has also failed, both faces are rebuilt. The inner timber is replaced with a suitable lintel, and the outer arch is reformed in front. The two are worked in sequence so the wall is supported throughout.
Best for: Arches with a failed timber or inner face
From first photo to finished repair
Choose reinforce or rebuild
We recommend reinforcement where the arch is sound and only slightly displaced, and a rebuild where it has dropped badly or bricks are loose. If the wall beside the opening is moving, that is dealt with first.
Support the opening
Props carry the brickwork above, and for a rebuild a former is made to the exact profile of the arch. The window or door frame is protected so it is not asked to carry any load.
Strike the former and point
Once the mortar has cured enough, the former and props are removed. Joints are finished to match the surrounding wall, and any cracks running from the arch into the wall are repaired at the same visit.
Symptoms that point to brick arch repairs
- Mortar falling out of the arch joints after frosty weather
- A flat arch that has started to sag into a shallow curve
- Gaps opening between arch bricks at the top or bottom edge

Frequently asked questions
What is the price of brick arch repairs in Thurso?
Guide prices for brick arch repairs in Thurso start from about £380 per arch, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out brick arch repairs in Thurso?
Survey visits to Thurso are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Does the ground around Thurso cause cracking?
The Highlands and Moray are hard rock and glacial deposits with little shrinkable clay; exposure, steep sites and older stone buildings drive most structural work. Only an investigation can say why a particular building has moved.
Should a brick arch be repaired with lime mortar?
On older houses built with soft bricks and lime, yes, in most cases. Lime mortar lets the wall breathe and is weaker than the brick, so any movement or frost damage happens in the joints rather than the bricks. Modern hard brickwork can take a cement-based mortar.
Can a dropped arch be repaired without rebuilding it?
Yes, if the drop is small and the brickwork is in good condition. Bars bonded into the joints above can take the load off the arch and hold it in place. If the bricks are loose or the arch has dropped badly, rebuilding is the more reliable repair.
