Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How we handle external mastic in Bradwell
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant 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 damp patches traced to an open external joint, we can put it right, on copings & trims, concrete & block and joints between brick and frames alike.
Houses in smaller places like Bradwell can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
Every job is covered by our one-year guarantee, wherever you are in Milton Keynes.

Why act early in Bradwell
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In an older home around Bradwell, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access. Parking around Bradwell is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Never let anyone fill a movement joint with mortar
- Avoid pressure-washing directly into sealant joints
- Check external joints each spring
- Have failed joints looked at early
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

What external mastic looks like in Bradwell
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. With historic houses such as Linford Manor (about 2 miles north-east) nearby, there’s older building stock in the area around Bradwell as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St Lawrence include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Milton Keynes Central station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Bradwell Village School? Then larger buildings have long runs of movement joint that eventually need resealing.

Your questions about external mastic in Bradwell
Do you cover smaller places like Bradwell?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Should the sealant in an older Bradwell home be renewed?
Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant won’t stick to old, so the old bead has to come out completely first.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
What should I tell you?
Let us know what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
