About our new build mastic in Watch House Green
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you’re dealing with smeared, uneven beads picked up at snagging and gaps opening as the house dries out and settles, we can put it right, on windows & doors, plot handovers and bathrooms & en suites alike.
Around Watch House Green, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with our one-year guarantee, wherever you are in Essex.

How to look after the new joints
So the new joints stay in good condition:
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we’re called out for in Watch House Green
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
People normally contact us after spotting something like this:
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Braintree station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Whether they’re fully insured
- Who turns up on the day
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
Your questions about new build mastic in Watch House Green
Do you cover smaller places like Watch House Green?
Yes, Watch House Green is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Braintree station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Honest limits
We’ll always be straight with you, so here’s what new sealant will not do:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
