About our external mastic in Beauworth
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you’re dealing with leaking joints around cladding and façade panels and cracked joints where brick meets render or frames, we can help.
External sealant needs dry, clean surfaces, so work around Beauworth is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Beauworth buildings and the weather
With historic houses such as Hinton Ampner House (about 1.5 miles north-east) nearby, there’s older building stock in the area around Beauworth as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Beauworth, as everywhere, external mastic is only as good as the preparation behind it.

What else we do in Beauworth
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. In a small place like Beauworth, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Mention any parking rules near the property

Advice
When it is not the sealant
It helps to know what we can’t do too:
- Render that is blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

What affects the quote in Beauworth
You will get a clear quote before any work starts. It’s based on:

Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Show decorators and builders where the movement joints are
- Do not let climbing plants root in the sealant
- Keep water from gutters off the wall
- Make sure movement joints are not pointed over
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Why deal with it now?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way. Around Beauworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

FAQs for Beauworth
What guarantee comes with external mastic in Beauworth?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Beauworth in your area for external mastic?
Yes. Our work covers London and the South East, and Beauworth is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
When will the joints need doing again?
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.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When to call us in Beauworth
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Any of these means the joints need attention:
- Brick movement joints where the sealant has split
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
Homes close to Church of St James include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
