Advice
New build mastic in Old Warren, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. If you have sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home, we can help, on plot handovers, windows & doors and bathrooms & en suites alike.
Around Old Warren, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What new build mastic looks like in Old Warren
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Old Warren, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Aldermaston station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Common questions in Old Warren
Is Old Warren within the area you cover?
Yes, Old Warren is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Aldermaston station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote and our work is guaranteed for a year.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can. We will tell you if anything on it is not a sealant job.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Old Warren, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How to look after the new joints
To keep the joints looking good and working properly:
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.

How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
