Why act early in Wendens Ambo
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Wendens Ambo, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

New build mastic in Wendens Ambo
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on plot handovers, bathrooms & en suites and show homes, and common reasons people get in touch are internal frame sealant that has split and joints pulling apart as timber shrinks.
For a small place like Wendens Ambo, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Our work is backed for twelve months, in Wendens Ambo and everywhere else we cover.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It generally takes a few hours in a single home. In a small place like Wendens Ambo, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid running a DIY bead over the old one
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
Common questions in Wendens Ambo
I let a flat near Audley End station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

Can you do plot mastic on a new development?

What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.

Common problems we fix in Wendens Ambo
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Audley End station, the sealant around baths, showers and frames is worth checking in the first year or two.
