Wivelrod External Mastic
External mastic for Wivelrod and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
- Weathered mastic that no longer stretches
DIY versus a professional finish
If you’re 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 does not work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
External mastic in Wivelrod, done properly
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on joints between brick and frames, façade panels and concrete & block, and people most often call us about old sealant gone brittle and cracked and weeds or debris growing in open joints.
Older homes in small places like Wivelrod may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Wivelrod: your questions answered
I let a flat near Alton station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Do you cover smaller places like Wivelrod?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Do you work at height?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
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 and reseal when it splits.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
Why it’s worth doing now in Wivelrod
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Wivelrod can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What external mastic looks like in Wivelrod
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. With historic houses such as Bentworth Hall (about 0.8 miles north-west) nearby, there’s older building stock in the area around Wivelrod as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Chapel of Alton Abbey, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Alton station, split movement joints are easy to miss on a rental until damp shows inside.

Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. Somewhere like Wivelrod needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
What affects the quote in Wivelrod
The price is agreed before any work begins. It’s based on:
- The size of the job
- The old material and how stubborn it is
- Mould in or behind the old joints
- Working hours on commercial sites
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 the work is at height. Your quote takes all of that into account.
