The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. For a job in Willesborough, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

New build mastic in Willesborough
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, plot handovers and skirting & floors, and people most often call us about worktop and upstand sealant coming away and cracked sealant around new window and door frames.
If you’ve bought a new home in or near Willesborough, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you are covered
- Avoid running a DIY bead over the old one
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
Willesborough: your questions answered
Will you come out to Willesborough?
Yes, Willesborough 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.
I let a flat near Ashford International station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
How long will you be here?
Typically it takes a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll say how long yours will take.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we’ll do.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
In and around Willesborough, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Why it’s worth doing now in Willesborough
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Willesborough, 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.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why book with us
- Homes, businesses and hotels
- White, clear, grey or coloured to suit, where the product allows
- Fully insured
- Sanitary silicone with an anti-fungal additive in wet areas

When it is not the sealant
It helps to know what we cannot do:
- Structural cracks in walls or ceilings
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
