External mastic in Bracknell
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on copings & trims, render & cladding joints and brickwork movement joints, and people most often call us about joints with sealant missing in places and rain getting behind render or cladding at a joint.
Larger buildings in Bracknell have plenty of movement joints, cladding joints and roofline trims. When those fail, water gets behind the face of the building, often unseen until it shows inside.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Can I do it myself?
If you are set on DIY, put the effort into 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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a large rental market like Bracknell, tired sealant leads to tenant complaints about mould, damp and leaks. It’s simpler to sort between tenants than in the middle of a let.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

When to call us in Bracknell
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Keep an eye out for these signs:
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Failed seals between different materials
- Water getting into walls through failed joints
Managing a site like Ranelagh School? Then larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- What the cure time is
- Who turns up on the day
- How long the guarantee is
- What product goes in the joint
Aftercare tips
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Point out the joints to other trades
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
Walls and rooflines in Bracknell
Bracknell was built as one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so whole streets can have gutters, trims and wall joints reaching the end of their life together. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Holy Trinity Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Bracknell station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

FAQs for Bracknell
Can you do external mastic in Bracknell?
Yes, Bracknell is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Is it worth replacing old sealant in an older home in Bracknell?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. The key is cutting all the old sealant out, as new sealant won’t bond to it.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Different surfaces, different methods
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
