New build mastic in Lydden, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for internal frame sealant that has split and sealant applied over dusty or wet surfaces, across kitchens, show homes and windows & doors.
Older homes in small places like Lydden often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Looking after new joints is easy:
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Keep pictures and emails about snagging items
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

Related advice
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Common problems we fix in Lydden
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Common reasons people contact us include:
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
Around Lydden, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- What product goes in the joint
- What insurance they hold
- How much experience the applicator has
- How the joint is cleaned and prepared
What the job involves on each surface
Plot handovers
Send us the schedule and any sealant specification. We seal bathrooms, kitchens, frames and floors as agreed.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Lydden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
