How we handle external mastic in West Wellow
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. Typical jobs include old sealant gone brittle and cracked and brick movement joints where the sealant has split, on render & cladding joints, façade panels and concrete & block.
External sealant needs dry, clean surfaces, so work around West Wellow is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months.

Your questions about external mastic in West Wellow
Can you help a landlord with a rental near Romsey station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is West Wellow in your area for external mastic?
Yes, West Wellow is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Why deal with it now?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around West Wellow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Wash walls gently around the sealant
- Make sure movement joints are not pointed over
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.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible year round.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
External mastic in West Wellow: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Landford Manor (about 2 miles west) are a reminder that the area around West Wellow has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Romsey station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St Margaret, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Wellow School, its movement joints, gutters and trims need looking after like any other building’s.
