What sealant work can’t fix
It helps to know what we can’t do too:

- Cracking that points to a structural problem
- Plumbing faults behind the sealant

Other services in Askett
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
When to call us in Askett
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
The problems people usually mention when they call are:
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
- New-build shower sealant that has already split
If you’ve bought a new home near Monks Risborough station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Whether the sealant suits the joint
- How much experience the applicator has
- The length of the guarantee
- How the surfaces are prepared before sealing
DIY sealant or a professional job?
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, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Landlord and commercial work in Askett
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
