Cuddington: your questions answered
Is Cuddington in your area for external mastic?
Yes, Cuddington is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Will you come out to Cuddington?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
How we handle external mastic in Cuddington
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. Typical jobs include brick movement joints where the sealant has split and weeds or debris growing in open joints, across façade panels, concrete & block and brickwork movement joints.
Older homes in small places like Cuddington may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Cuddington needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

What affects the quote in Cuddington
Your quote is based on your job. We take into account:
- The size of the job
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Roughly how big the job is
- Access, such as stairs, a lift or height
- A few photos by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
- Movement that’s more than a sealant joint can take
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.

Cuddington buildings and the weather
With historic houses such as Waddesdon Manor (about 3.3 miles north) nearby, there’s older building stock in the area around Cuddington 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Haddenham & Thame Parkway station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Cuddington and Dinton CofE School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Cuddington is about 4 miles north-east of Thame, in Buckinghamshire. From the centre of Cuddington to the outskirts, external mastic is available for homes and businesses alike. Cuddington is one of 263 places in Buckinghamshire we cover for external mastic. Our Oxford page covers work nearby.

What we are called out for in Cuddington
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Most people get in touch after spotting something like this:
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
- Failed seals between different materials
- Sealant that has lost its bond to the brick or render
Homes close to Parish Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- What product goes in the joint
- Whether you can choose the colour
- Who does the work, and how experienced they are
- Is VAT in the price?
What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way. Around Cuddington, 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. Ask us for a quote and we will go through it with you.
