About our new build mastic in Ashdon
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. Common call-outs are for skirting joints opening in the first winter and cracked sealant around new window and door frames, on kitchens, show homes and plot handovers.
Older homes in small places like Ashdon often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

New homes and floors in Ashdon
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in Ashdon itself or nearby, the right material for each joint matters as much as a neat finish.

Ashdon questions
Will you come out to Ashdon?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with new build mastic in Ashdon?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Are you fully insured?
Yes, we are fully insured for every job we do.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Ashdon, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Aftercare tips
Good habits help new joints last longer. Our tips:
- Record problems with dated photos
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What we are called out for in Ashdon
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over dusty or wet surfaces
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
Around Ashdon, as everywhere, new build mastic is only as good as the preparation behind it.

What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In a small place like Ashdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
