Why it’s worth doing now in Hastings Old Town
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. In an older home around Hastings Old Town, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Hastings Old Town questions
Do you work for landlords with property near Hastings station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Does the coastal weather in Hastings Old Town affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Can you seal over the old sealant?
No. The old sealant always comes out first.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

The work generally takes anything from a few hours to several days, depending on the building.

If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Hastings Old Town buildings and the weather
Hastings Old Town is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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 landlords with property near Hastings station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Ark Castledown Primary Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

When to call us in Hastings Old Town
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Common reasons people contact us are:
- Gaps where render, brick and frames meet
- Failed sealant between panels on a façade
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
For an older house near a landmark such as Church of St Clement, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
