Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Small faults turn into leaks if left.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours in a single home. For a job in Larkhall, tell us where the work is, how to get in and where to park. Outside work depends on the weather, as sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

Advice
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Broken tiles or a split tray
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with

Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
