External Mastic in Bodicote
Problem with your movement joints in Bodicote? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Sealant that has lost its bond to the brick or render
- Cracked joints where brick meets render or frames
- Brick movement joints where the sealant has split
External mastic in Bodicote, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where mortar or filler would crack. We work on façade panels, joints between brick and frames and concrete & block, and the jobs we see most are gaps where render, brick and frames meet and damp patches traced to an open external joint.
Around Bodicote, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check external joints each spring
- Have failed joints looked at early
- Avoid pressure-washing directly into sealant joints
- Leave the joints unpainted unless we’ve said otherwise
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Common problems we fix in Bodicote
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
Look out for any of the following:
- Joints where the bead has come unstuck
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
For site and facilities teams at buildings such as Longford Park Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How the visit works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we explain the cure time before we leave. A visit to Bodicote is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention any tricky access
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Common questions in Bodicote
Will you come out to Bodicote?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Banbury station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Are you fully insured?
Yes, we’re fully insured for every job we do.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
How we quote for external mastic
We quote each job individually. These are the things that affect it:
- When we can work, for business premises
- The product the joint needs
- The number of rooms or windows
- Whether there’s mould to deal with
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
Why it’s worth doing now in Bodicote
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. In an older home around Bodicote, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Homes, businesses and hotels
- Anti-fungal sanitary silicone in wet areas
- We’re fully insured

Bodicote buildings and the weather
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. Historic houses like Broughton Castle (about 2.9 miles west) are a reminder that the area around Bodicote has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Banbury station? Then split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Church of St John the Baptist, an extension built onto an older house moves differently, and the joint between them takes the strain.
