External mastic in Marsh Benham: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Benham Park (about 0.7 miles east) nearby, there’s older building stock in the area around Marsh Benham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Stockcross C.E. School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Kintbury station? Then split movement joints are easy to miss on a rental until damp shows inside.

Common questions in Marsh Benham
Is Marsh Benham in your area for external mastic?
Yes. Our work covers London and the South East, and Marsh Benham is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
I let a flat near Kintbury station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
What is backing rod for?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
How much does external mastic cost in Marsh Benham?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does external mastic take?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the building. We’ll tell you when we quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Act on the first splits you see
- Do not let climbing plants root in the sealant
- Check external joints each spring
- Ask before painting over external sealant
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.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Cracking across the wall rather than at a joint
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Concrete & block
- Copings & trims
- Façade panels
- Joints between brick and frames
- Brickwork movement joints
- Render & cladding joints
Do you need external mastic in Marsh Benham?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
The most common problems we see are:
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
In the older streets around Church of St John, the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- How the colour is chosen
- What preparation is included
- Whether all the old sealant comes out first
- Is VAT in the price?
Why act early in Marsh Benham
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Marsh Benham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Old sealant always removed completely
- Neat joints and a tidy finish
- Domestic, commercial and hotel work
- Sealant colour chosen to suit
