External Mastic in Park Town
External mastic across Park Town and nearby, with every bit of old sealant taken out first.
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Have failed joints looked at early
- Fix overflowing gutters above sealed joints
- Look over the joints every year, ideally after winter
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
External mastic in Park Town, done properly
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We’re often asked to deal with movement joints with cracked, split or missing sealant and panel joints letting water in, on brickwork movement joints, concrete & block and joints between brick and frames.
Houses in smaller places like Park Town can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Park Town buildings and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Holywell Manor (about 0.9 miles south-east) are a reminder that the area around Park Town 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.
For site and facilities teams at buildings such as Wychwood School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Oxford station? Then split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Park Town
Is Park Town within the area you cover?
Yes. Park Town is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Oxford station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How do I get a quote for external mastic in Park Town?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
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.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
When to call us in Park Town
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
These are the problems we are asked about most:
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
Historic houses such as Holywell Manor, about 0.9 miles south-east, show how far back building around Park Town goes, and older homes nearby need a sealant that suits their walls.

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How the visit works
The work is kept neat and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the building.

- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about parking restrictions

How the job changes by surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
