New build mastic for homes and businesses in Standon
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you are dealing with cracks appearing as a new home settles and gaps between new skirting and floors, we can help, whatever the surface.
Older homes in small places like Standon often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by our 12-month guarantee, wherever you are in Hertfordshire.

Aftercare tips
Looking after new joints is easy:
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Why act early in Standon
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. Where a wall is exposed, as many are in small places like Standon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots. In a small place like Standon, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention any tricky access
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Standon questions
Can you do new build mastic in Standon?
Yes, Standon is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Is Standon within the area you cover?
Yes, Standon is covered. We work across 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 hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
