Planned mastic for Wellow portfolios
The sea is no more than about 2 miles from Wellow. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. Wellow sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
With historic buildings such as Mottistone Manor (to the south of Wellow) in the wider area, owners of older properties around Wellow should expect mastic to need a product that suits old masonry. Trustees of buildings like Wellow Baptist Church can bring frame and external mastic into a planned maintenance list.

FAQs: Wellow
Is Wellow off your patch?
Not at all. Wellow is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on block-wide or estate-wide mastic work in Wellow?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we’ll give a fixed quote.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. One visit to deal with every failing joint makes more sense than several trips to a place like Wellow. Send photographs of each area and we will quote for the lot.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Signs you need mastic sealing in Wellow
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Site and facilities staff are often the first to spot these:
- Water getting in round frames after rain
- Old repairs sealed over failed mastic
- Communal area joints that look neglected
- Brittle perimeter mastic across a building
Schools and community buildings such as Shalfleet Church of England Primary School need frame and external mastic kept sound like any building.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
