Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Common problems we fix in Haverstock
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain and eventually tear.
If you can see any of these, it’s time to have the joints looked at:
- Repeated reseals that do not last
- Shower leaks reaching the floor below
- Mouldy bathrooms flagged at a tenancy check
- Large numbers of bathrooms needing the same work
Managing a site like Fine Arts College? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
