Ledborough External Mastic
External mastic in Ledborough from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
- Rain getting behind render or cladding at a joint
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Walls that need new movement joints cut into them
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Render & cladding joints
- Façade panels
- Joints between brick and frames
External mastic in Ledborough, done properly
On houses, flats and commercial buildings across Ledborough, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on façade panels, render & cladding joints and joints between brick and frames, and people most often call us about hard, crazed mastic that has stopped moving and leaking joints around cladding and façade panels.
External sealant needs dry, clean surfaces, so work around Ledborough is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Every job is covered by our one-year guarantee, wherever you are in Buckinghamshire.

What else we do in Ledborough
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
How we quote for external mastic
We do not publish a price list. The quote depends on:
- The size of the job
- Any working-time requirements on site
- The number of rooms or windows
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What we need to know
When you call or email, these details help:
- The address or postcode of the job
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
When to call us in Ledborough
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
The most common problems we see are:
- Cracked joints where brick meets render or frames
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Joints with sealant missing in places
In the older streets around Church of St Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain.
Before you book anyone
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Whether they’re fully insured
- Whether all the old sealant comes out first
Why deal with it now?
A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a small place like Ledborough, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What you get with us
- Experience in homes, commercial sites and hotels
- Approved under the ARBOMaster scheme
- A choice of colours where the product allows
- We leave the area clean and tidy

External mastic in Ledborough: local notes
Historic houses like Cliveden (about 4.6 miles south-west) are a reminder that the area around Ledborough has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Rented homes near Beaconsfield station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as St Mary and All Saints CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.

We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
