How we handle external mastic in Brookhampton
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. Common call-outs are for movement joints filled with mortar instead of sealant and weeds or debris growing in open joints, on concrete & block, brickwork movement joints and copings & trims.
Somewhere as small as Brookhampton, 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.
We stand behind the work with a 12-month guarantee.

FAQs for Brookhampton
Can you help a landlord with a rental near Radley station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can you do external mastic in Brookhampton?
Yes. We work across London and the South East, and Brookhampton is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
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.
What does external mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
When to call us in Brookhampton
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Failed seals between different materials
- Plants rooting in failed movement joints
Schools such as Stadhampton Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- What the cure time is
- What guarantee comes with the work
When something else is needed
It helps to know what we can’t do:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Render that is blown, hollow or coming away
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Why act early in Brookhampton
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. In a small place like Brookhampton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep water from gutters off the wall
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Look over the joints every year, ideally after winter
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Brookhampton buildings and 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. With historic houses such as Garsington Manor (about 2.7 miles north-west) nearby, there’s older building stock in the area around Brookhampton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Radley station, split movement joints are easy to miss on a rental until damp shows inside.

Advice
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
