External mastic for homes and businesses in Ashurst
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. If you have moss and dirt in joints with no sealant left and rigid filler in a joint that should flex, we can put it right, whatever the surface.
Older homes in small places like Ashurst may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What else we do in Ashurst
Outside joints around Ashurst
Ashurst is within about 3 miles of 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. Historic houses like Southampton Tudor House and Garden (about 4.8 miles east) are a reminder that the area around Ashurst has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near Colbury Christ Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Ashurst New Forest station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Foxhills Infant School, its movement joints, gutters and trims need looking after like any other building’s.

Is external mastic in a coastal place like Ashurst any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before we start, matched as closely as the range allows.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Why act early in Ashurst
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Ashurst, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What you get with us
- White, clear, grey or another colour, product permitting
- Colour picked to suit the job
- Domestic, commercial and hotel work
- Quality sealants from Arbo and Everbuild
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

- Copings & trims
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
- Brickwork movement joints
How the job changes by surface
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant so neither cracks the other.
