External Mastic in Butt's Green
External mastic across Butt's Green and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
Why act early in Butt's Green
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Butt's Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

External mastic for homes and businesses in Butt's Green
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render. If you are dealing with cracked joints where brick meets render or frames and brick movement joints where the sealant has split, we can help.
Older homes in small places like Butt's Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

External mastic in Butt's Green: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Danbury Place (about 1.1 miles north-east) nearby, there’s older building stock in the area around Butt's Green as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Beaulieu Park 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 The Sandon School, its movement joints, gutters and trims need looking after like any other building’s.

The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere like Butt's Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

Do you cover smaller places like Butt's Green?

Do you work for landlords with property near Beaulieu Park station?

Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we will confirm the access.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Are you insured?
Yes. Full insurance covers our work.
Should I point up the gap in my brickwork?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Fix overflowing gutters above sealed joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
What we are called out for in Butt's Green
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.
Look out for any of the following:
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
Danbury Place, about 1.1 miles north-east, is one of the historic houses in the wider area around Butt's Green, and older homes nearby need a sealant that suits their walls.

What affects the quote in Butt's Green
There’s no set price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- Which sealant suits the joint
- Access and height
- The size of the job
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.
Helping us quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- A few pictures by email, if you can
- The type of property
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.
Should I try it myself first?
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’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 does not work out, we can still put it right.
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- Cracks in the bricks or render themselves, away from the joints
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
