The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a job in Seaford, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

How we handle new build mastic in Seaford
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on plot handovers, windows & doors and kitchens, and people most often call us about gaps between new skirting and floors and new-build shower sealant that has already split.
In a town like Seaford, skirting and floor joints open up as homes settle and floors move with the seasons. A flexible sealant, rather than rigid filler, keeps those joints closed.
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.

Common questions in Seaford
Is Seaford in your area for new build mastic?
Yes. Our work covers London and the South East, and Seaford is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Is there a guarantee on new build mastic in Seaford?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
How long will you be here?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we’ll say so.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
When to call us in Seaford
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry first.
Look out for these signs:
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
- Internal frame sealant that has split
In and around Seaford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Seaford
A hairline gap at a skirting can wait, but a leaking seal can’t. If you are unsure which you have, phone 0345 464 0079 or drop us an email with pictures. In Seaford, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Raise failed sealant with the developer while you are covered
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
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.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
