External mastic in Two Mile Ash, done properly
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We work on render & cladding joints, joints between brick and frames and copings & trims, and common reasons people get in touch are joints with sealant missing in places and cracked joints where brick meets render or frames.
In and around Two Mile Ash, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Make sure movement joints aren’t pointed over
- Walk round the building once a year and look at the joints
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint cannot move, the wall finds another way, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
How we quote for external mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What we need to know
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- Whether it’s a home or a business
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or drop us an email.
Walls and rooflines in Two Mile Ash
Milton Keynes, which Two Mile Ash is part of, is 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Milton Keynes Central station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of the Holy Cross, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Two Mile Ash School, larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two.
Landlord and commercial work in Two Mile Ash
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours to a few days, depending on the length of joint and the access, and we tell you how long to leave it before we go. In a smaller place like Two Mile Ash, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- 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.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Clear the area around the work

Questions from Two Mile Ash
Should the sealant in an older Two Mile Ash home be renewed?
Normally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Do you work for landlords with property near Milton Keynes Central station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Can you reach joints on upper floors?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint doesn’t draw the eye.
What we cannot put right
Before you book, it’s worth knowing the limits:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Adding movement joints to masonry that has none
- Loose or hollow render, which needs re-rendering
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
