Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Record problems with dated photos
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

Related advice
Landlord and commercial work in Loosley Row
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
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.
Why it’s worth doing now in Loosley Row
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Loosley Row, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Common questions in Loosley Row
Is Loosley Row in your area for new build mastic?
Yes. Our work covers London and the South East, and Loosley Row is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Loosley Row?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
