New build mastic in Littlehampton
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for sealant work across a run of new homes and sealant applied over dusty or wet surfaces, on show homes, kitchens and skirting & floors.
Shops and business units around Littlehampton have floors that see a lot of traffic. Threshold and floor joints are best resealed before their edges start breaking away.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Littlehampton questions
Is Littlehampton in your area for new build mastic?
Yes. We work across London and the South East, and Littlehampton is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Littlehampton station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
What new build mastic looks like in Littlehampton
Littlehampton is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

The process

In Littlehampton, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we work through your snagging list or plot schedule with you.
- 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 are given the cure time.
How to prepare
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

Advice
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Quotes for new build mastic in Littlehampton
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- How easy the joints are to reach
- How many areas need sealing
- The product the joint needs
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
Asking for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Where the property is
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will talk you through the work before giving you a price.
Common problems we fix in Littlehampton
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The problems people usually mention when they call are:
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
For new homes near Littlehampton station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Are they insured?
- Whether they seal over old material or remove it
- What guarantee comes with the work

Why act early in Littlehampton
A hairline gap at a skirting can wait, but a leaking seal cannot. If you are unsure which you have, phone 0345 464 0079 or email us with photos and we’ll give you a straight answer. In a family home in Littlehampton, a failed seal around a bath or a frame lets water into places you can’t see, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.
