Waltham Abbey External Mastic
Professional external mastic in and around Waltham Abbey, with every bit of old sealant taken out first and a 12-month guarantee.
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
- Failed seals between different materials
How to look after the new joints
After the cure time, these simple habits help:
- Clear growth from the base of walls and joints
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Leave the joints unpainted unless we’ve said otherwise
Do not 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.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
External mastic in Waltham Abbey, done properly
For buildings in Waltham Abbey, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Common call-outs are for rain getting behind render or cladding at a joint and sealant pulling away from one side of the joint, across joints between brick and frames, concrete & block and brickwork movement joints.
Around Waltham Abbey, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.
There’s a 12-month guarantee on every job.

What else we do in Waltham Abbey
What affects the quote in Waltham Abbey
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- When we can work, for business premises
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- Roughly how big the job is
- The address or postcode of the job
For external mastic in Waltham Abbey, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Why act early in Waltham Abbey
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
Rather than a set price list, 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.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Walls and rooflines in Waltham Abbey
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Forty Hall (about 3.6 miles west) are a reminder that the area around Waltham Abbey has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Waltham Cross station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Waltham Abbey Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Waltham Holy Cross Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
Waltham Abbey questions
I let a flat near Waltham Cross station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is there a guarantee on external mastic in Waltham Abbey?
All our work, in Waltham Abbey and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How long should I leave it?
It depends on the product. Before we leave, we will tell you the cure time.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. Then the sealant bonds to two faces and can move.
The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work normally takes a few hours for a handful of joints, longer for a whole elevation. For a job in Waltham Abbey, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
