External mastic in Winchfield
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We work on joints between brick and frames, façade panels and concrete & block, and people most often call us about rain getting behind render or cladding at a joint and hard, crazed mastic that has stopped moving.
Somewhere as small as Winchfield, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Winchfield buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Oakwood Infant School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Mary the Virgin, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Winchfield station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Don’t paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Subsidence or other structural problems
- Cracks in the bricks or render themselves, away from the joints
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What happens if it’s left?
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Winchfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Surface by surface
Copings and trims
Copings expand and contract through the day, so a flexible sealant suits them best year round.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of joints, longer for a whole elevation from start to finish. Somewhere as small as Winchfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Clear the area around the work
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

How long does external mastic last?
It depends on the exposure, the movement and the product. Treat it as a maintenance item and look at it yearly.
How much does external mastic cost in Winchfield?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Does someone need to be in?

Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move.
