External mastic in Hurst
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have movement joints filled with mortar instead of sealant and sealant that has lost its bond to the brick or render, we can put it right, on copings & trims, render & cladding joints and concrete & block alike.
Somewhere as small as Hurst, homes and farm buildings often face open ground, 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.
All of our work is guaranteed for twelve months.

Different surfaces, different methods
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a handful of joints, longer for a whole elevation from start to finish. In a small place like Hurst, access is usually the main thing to plan. 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

What external mastic looks like in Hurst
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Twyford station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Hurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the 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.
What we are called out for in Hurst
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Sealant pulling away from one side of the joint
- Leaking joints around cladding and façade panels
- Damp patches traced to an open external joint
- Rigid filler in a joint that should flex
Managing a site like St Nicholas Church of England Primary? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- Whether the sealant suits the joint
- Whether they’re fully insured
- How the colour is chosen
- How long to leave it before use
What sealant work can’t fix
We won’t take on work that will not last, so these are the limits:
- Cracking across the wall rather than at a joint
- Movement that is more than a sealant joint can take
- Failed render or damaged cladding panels
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Façade panels
- Joints between brick and frames
