FAQs Archive - Northwest Wall Ties

Q: Should I repair stepped cracks before they get worse?

It is sensible to have significant, widening or recurring cracks assessed rather than simply filling them and leaving them. Early assessment can help identify whether there is ongoing movement and what type of repair may be appropriate.

Q: Do you offer a guarantee on crack stitching?

Yes, our crack stitching work is fully guaranteed , giving you added confidence in the quality and durability of the repair.

Q: How much does crack stitching cost?

The cost depends on factors such as the length and severity of the crack, access, number of stitching bars required, wall construction and any additional repairs needed . We can assess the affected area and provide a free, no-obligation quote.

Q: How do I know if my wall needs crack stitching?

There is no single crack pattern that confirms crack stitching is required. An assessment should consider the type, width, direction and location of the crack , as well as signs of movement, settlement, wall tie problems or inadequate restraint.

Q: Can you stitch a crack that has been repaired before?

Potentially. Cracks that have previously been filled or repaired can sometimes be stitched, but the existing repair material may need to be removed or prepared appropriately. The condition of the masonry and reason for the previous failure should be considered.

Q: Is crack stitching better than simply filling a crack?

Simply filling a crack may improve its appearance but does not necessarily reinforce the masonry. Crack stitching provides mechanical reinforcement across the affected area , making it a more substantial repair where the masonry is suitable and reinforcement is required.

Q: How long does crack stitching last?

When the correct repair method and suitable materials are used, crack stitching is intended to provide a long-term reinforcement of the masonry . The longevity of the repair also depends on the condition of the existing wall and whether any underlying cause of movement has been addressed.

Q: Can a lack of restraint cause cracks in brickwork?

Yes. Masonry requires suitable restraint to help control movement, particularly around areas such as gable walls, corners and openings . Inadequate restraint can allow movement or displacement of the masonry and may contribute to cracking.

Q: Do wall ties cause stepped cracking?

Wall tie problems can contribute to movement and cracking in some cavity walls , particularly where ties are missing, inadequate, deteriorated or not providing sufficient restraint. However, stepped cracking has many possible causes, so the presence of a crack does not automatically mean the wall ties are responsible.

Q: Can crack stitching repair internal cracks?

It depends on the construction and cause of the cracking. Internal cracks can sometimes be related to movement within the masonry, but they may also have completely different causes. The crack should be assessed before deciding whether crack stitching is suitable.
