How we handle external mastic in Goose Hill
For buildings in Goose Hill, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you have water getting into walls through failed joints and weathered mastic that no longer stretches, we can help, whatever the surface.
Older homes in small places like Goose Hill may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
A one-year guarantee comes as standard.

What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:

- The size of the job
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not let climbing plants root in the sealant
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Keep water from gutters off the wall
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Outside joints around Goose Hill
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Thatcham station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Ashford Hill Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant is not too deep.
Landlord and commercial work in Goose Hill
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why it’s worth doing now in Goose Hill
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Goose Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Goose Hill questions
Is Goose Hill in your area for external mastic?
Yes. We work across London and the South East, and Goose Hill is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Can you help a landlord with a rental near Thatcham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working and can lead to cracking. A flexible sealant is the right fill.
When will the joints need doing again?
It varies from wall to wall: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer.
Common problems we fix in Goose Hill
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
For an older house near a landmark such as Church of St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.
