New build mastic in Hastings Old Town
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 cracked caulk along new skirting and gaps behind new kitchen upstands, across kitchens, show homes and windows & doors.
If you’ve bought a new home in or near Hastings Old Town, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
Every job is covered by a 12-month guarantee, wherever you are in East Sussex.

What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. The work normally takes anything from a few hours to several days, depending on the number of plots. Parking around Hastings Old Town is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In a smaller place like Hastings Old Town, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

What affects the quote in Hastings Old Town
There’s no set price list, because jobs vary so much. What we look at:
- The size of the job
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The rough size of the job
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
What we are called out for in Hastings Old Town
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Signs it’s time to call us include:
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
In and around Hastings Old Town, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What new build mastic looks like in Hastings Old Town
Hastings Old Town 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Hastings station, the sealant around baths, showers and frames is worth checking in the first year or two.
