Outside joints around Babbs Green
With historic houses such as Much Hadham Palace (about 3.2 miles north-east) nearby, there’s older building stock in the area around Babbs 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Ware station, split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How we handle external mastic in Babbs Green
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for brick movement joints where the sealant has split and leaking joints around cladding and façade panels, across façade panels, joints between brick and frames and copings & trims.
Around Babbs Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Honest limits
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Cracks in the bricks or render themselves, away from the joints
- Movement that’s more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

What else we do in Babbs Green
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Point out the joints to other trades
- Leave the joints unpainted unless we’ve said otherwise
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere like Babbs Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

What we are called out for in Babbs Green
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
People generally contact us after spotting something like this:
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
For site and facilities teams at buildings such as Wareside Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Surface by surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly where it can be done safely.
Common questions in Babbs Green
Will you come out to Babbs Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Babbs Green in your area for external mastic?
Yes, Babbs Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
