- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
How we handle new build mastic in Heath Park
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 sealant applied over dusty or wet surfaces and gaps between new skirting and floors, across windows & doors, bathrooms & en suites and show homes.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Big or small, you get the same 12-month guarantee in Heath Park and across Greater London.

Can I do it myself?
If you’re 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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why act early in Heath Park
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Heath Park, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

What else we do in Heath Park
What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In Heath Park, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with right away
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
