When to call us in Ashfield
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
If you can see any of these, it’s time to have the joints looked at:
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
Homes close to Church of St Boniface include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic for homes and businesses in Ashfield
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We work on brickwork movement joints, render & cladding joints and concrete & block, and people most often call us about weeds or debris growing in open joints and brick movement joints where the sealant has split.
In a village or hamlet like Ashfield, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
FAQs for Ashfield
Can you help a landlord with a rental near Romsey station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Ashfield?
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 work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
What’s an expansion joint in brickwork?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
What else we do in Ashfield
What the job involves on each surface
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one.
How it works
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Somewhere as small as Ashfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Related advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Older cottages and farmhouses around Ashfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- We never seal over old sealant
- 12-month guarantee on every job
- Trusted Arbo and Everbuild sealants

What external mastic looks like in Ashfield
Ashfield is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as South Stoneham House (about 4.8 miles east) nearby, there’s older building stock in the area around Ashfield as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Romsey station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Oasis Academy Lord's Hill, larger buildings have long runs of movement joint that eventually need resealing.

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
