New build mastic in New Pound, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. If you are dealing with gaps opening as the house dries out and settles and frame joints opening as the plaster dries, we can help.
Older homes in small places like New Pound 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 something isn’t right with it in that time, tell us and we’ll put it right.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for new build mastic
You will get a clear quote before we start. It’s based on:
- The amount of work
- Which sealant suits the joint
- Whether the work is at height
- How many areas need sealing
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
What we need to know
Before you ask for a quote, have a think about:
- The address or postcode of the job
- The rough size of the job
- Any access issues, like height or stairs

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like New Pound, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- 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.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Advice
What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Record problems with dated pictures
- Check bath and shower seals every few months as the house settles
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
New Pound: your questions answered
Will you come out to New Pound?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover New Pound for new build mastic?
Yes. Our work covers London and the South East, and New Pound is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
What does new build mastic cost?
We do not 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.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.

Do you need new build mastic in New Pound?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Keep an eye out for any of the following:
- Internal frame sealant that has split
- Cracks appearing as a new home settles
- New-build shower sealant that has already split
- Messy sealant that spoils new finishes
If you’ve bought a new home near Wateringbury station, the sealant around baths, showers and frames is worth checking in the first year or two.
