External mastic for homes and businesses in Ware
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 façade panels, render & cladding joints and joints between brick and frames, and common reasons people get in touch are damp patches traced to an open external joint and old sealant gone brittle and cracked.
Garage door frames, porches and roofline trims are all part of external work in a town like Ware. Each joint between different materials moves in its own way, so the sealant has to cope with that.
Big or small, it’s backed by our one-year guarantee in Ware and across Hertfordshire.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.

Questions from Ware
Do you cover Ware for external mastic?
Yes, Ware is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.

What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
What colours does the sealant come in?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Parking in a town like Ware is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Advice
What happens if it’s left?
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 pays to do it properly once. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Ware they get worse with every use. Now is the easy time to put it right.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into 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.
What external mastic looks like in Ware
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Christ Church Ware, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Ware station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Schools such as Christ Church CofE (VA) Primary School and Nursery are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
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 which cost more to put right than the joint.
