How we handle new build mastic in Old Town
We work in new homes and on new-build sites across Old Town. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on skirting & floors, kitchens and plot handovers, and common reasons people get in touch are new-build shower sealant that has already split and cracked caulk along new skirting.
For a new home in or near Old Town, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Big or small, it’s backed by our one-year guarantee.

Common problems we fix in Old Town
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.
It’s worth asking for a quote if you see:
- Second-fix sealing on new plots
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Cracked sealant around new window and door frames
Around Old Town, as everywhere, new build mastic is only as good as the preparation behind it.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- A tray or bath that is not properly supported, until it’s fixed
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

New build mastic in Old Town: local notes
Old Town is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Eastbourne station, it’s worth checking the sealant early, while snags are still fresh.
Old Town is about 1 mile south-west of Eastbourne, in East Sussex. Old Town gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 289 towns and villages across East Sussex, large and small. For nearby work, see our Brighton page, about 18 miles away.
All of BN21, BN20 and BN22 is within our area for new build mastic. Local streets include Love Lane, Mill Road and Greys Road.

We also work in nearby towns such as Hastings (15 miles north-east), Bexhill-on-Sea (10 miles north-east), Seaford (7 miles west), Lewes (13 miles north-west), Hailsham (6 miles north) and St Leonards (14 miles north-east).
Landmarks near Old Town
Locally, jobs take us to homes and businesses close to Motcombe Infants' School, Gildrege Park and WMG Academy for Young Engineers, among other places.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.

How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered as agreed.
Landlords, agents and businesses in Old Town
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Old Town and across East Sussex. Several sites can be quoted together.
How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots from start to finish. A visit to Old Town is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- Let us know about parking restrictions
- Move anything stored near the joints
- Keep children and pets away from the work area

Do you use white or clear sealant?
