Walls and rooflines in Owslebury Bottom
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Owslebury Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St Andrew, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Shawford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How we handle external mastic in Owslebury Bottom
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. If you have water getting into walls through failed joints and panel joints letting water in, we can put it right, whatever the surface.
In a village or hamlet like Owslebury Bottom, 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.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What affects the quote in Owslebury Bottom
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The number and length of the joints
- Mould in or behind the old joints
- The type of sealant required
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Any previous sealing or DIY work
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or send us an email.
What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. In a small place like Owslebury Bottom, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Related advice
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
FAQs for Owslebury Bottom
Will you come out to Owslebury Bottom?

What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so it doesn’t stand out.
What the job involves on each surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Send us any details you have about the façade.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Make sure movement joints aren’t pointed over
Do not let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Why act early in Owslebury Bottom
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Where a wall is exposed, as many are in small places like Owslebury Bottom, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
