How we handle external mastic in Newport
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on façade panels, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are movement joints with cracked, split or missing sealant and hard, crazed mastic that has stopped moving.
In a smaller place like Newport, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
Each job carries a 12-month guarantee, whatever its size.

Landlord and commercial work in Newport
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Around Newport, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us

Common problems we fix in Newport
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
People generally contact us when they notice something like this:
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Weathered mastic that no longer stretches
- Rigid filler in a joint that should flex
Managing a site like Joyce Frankland Academy? Then larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before booking
- What the cure time is
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

External mastic in Newport: 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. Historic houses like Audley End House (about 2.4 miles north) are a reminder that the area around Newport has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Newport (Essex) station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain.

Your questions about external mastic in Newport
Do you cover Newport for external mastic?
Yes, Newport is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Newport?
Yes, Newport is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
What information do you need?
A short description and the location, with photos by email if possible. If we need more, we will ask.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
