What external mastic looks like in Nuptown
With historic houses such as St Leonard's Hill (about 3.5 miles east) nearby, there’s older building stock in the area around Nuptown as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Michael and All Angels, the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in Nuptown
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. Common call-outs are for joints where the bead has come unstuck and cracked joints where brick meets render or frames, on joints between brick and frames, façade panels and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Nuptown is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Nuptown, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Advice
What happens if it’s left?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. Around Nuptown, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Make sure movement joints are not pointed over
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
- Wash walls gently around the sealant
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Render that is blown, hollow or coming away
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Nuptown: your questions answered
Will you come out to Nuptown?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Bracknell station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can you seal joints between two different materials?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
DIY sealant or a professional job?
What a professional job adds is preparation and the right 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Common problems we fix in Nuptown
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
It’s worth asking for a quote if you see:
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
If you let a flat or house near Bracknell station, outside joints that have cracked can let damp into a rental, so check them between lets.
