How we handle external mastic in Eversholt
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. Typical jobs include weeds or debris growing in open joints and rain getting behind render or cladding at a joint, across copings & trims, concrete & block and façade panels.
Around Eversholt, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the building. Somewhere as small as Eversholt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
Looking after new joints is easy:
- Never let anyone fill a movement joint with mortar
- Leave the joints unpainted unless we have said otherwise
- Check external joints each spring
- Clear growth from the base of walls and joints
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead and let water in behind.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.

External mastic in Eversholt: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Flitwick Manor (about 1.9 miles east) are a reminder that the area around Eversholt has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Flitwick station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Do you need external mastic in Eversholt?
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Keep an eye out for these signs:
- Joints pointed up with cement by mistake
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
Homes close to Church of St Lawrence include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

FAQs for Eversholt
I let a flat near Flitwick station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you cover Eversholt for external mastic?
Yes. We work across London and the South East, and Eversholt is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Can you match the colour of my brickwork?
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.
How long will you be here?
Typically it takes a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Are you fully insured?
Yes. We’re fully insured.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides, primed where needed.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Eversholt
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. Where a wall is exposed, as many are in small places like Eversholt, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
