External Mastic in Tiddington
Sealing brickwork movement joints, render, cladding and façade joints for homes and businesses in Tiddington and across Oxfordshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Failed seals between different materials
How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
External mastic in Tiddington, done properly
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you have cracked joints where brick meets render or frames and old sealant gone brittle and cracked, we can put it right, on joints between brick and frames, concrete & block and render & cladding joints alike.
In a village or hamlet like Tiddington, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Tiddington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

How to look after the new joints
After the cure time, these simple habits help:
- Wash walls gently around the sealant
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
External mastic in Tiddington: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Adwell House (about 4.5 miles south-east) are a reminder that the area around Tiddington has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Helen, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Around Tiddington, as everywhere, external mastic is only as good as the preparation behind it.

Questions from Tiddington
Is external mastic in Tiddington guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Tiddington for external mastic?
Yes. We work across London and the South East, and Tiddington is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
What we seal
- Joints between brick and frames
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Façade panels
- Copings & trims
Leave it or put it right?
Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together. Where a wall is exposed, as many are in small places like Tiddington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
