What we’re called out for in Theydon Bois
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
If you can see any of these, it’s time to have the joints looked at:
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
In and around Theydon Bois, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What the cure time is
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- How the colour is chosen
How we handle new build mastic in Theydon Bois
Across Theydon Bois, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on plot handovers, windows & doors and bathrooms & en suites, and the jobs we see most are cracked caulk along new skirting and gaps opening as the house dries out and settles.
In smaller places like Theydon Bois, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. Sealant work across the plot is covered as agreed.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Landlords, agents and businesses in Theydon Bois
Letting agents and landlords in Theydon Bois can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Aftercare tips
Looking after new joints is easy:
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
Leave it or put it right?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Around Theydon Bois, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Is Theydon Bois within the area you cover?
Yes, Theydon Bois is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What colour sealant will you use?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
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.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
