How we handle external mastic in Mursley
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We take the old material out and do it properly. If you have old sealant gone brittle and cracked and rain getting behind render or cladding at a joint, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Mursley is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
You get a one-year guarantee, the same in Mursley as everywhere else we work.

Outside joints around Mursley
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Bletchley Park (about 4.5 miles north-east) are a reminder that the area around Mursley has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Mursley Church of England School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

What affects the quote in Mursley
We quote each job individually. This is what makes a difference:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- How much there is to do
- Working hours on commercial sites
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What we need to know
To help us quote quickly, please include:
- Where the property is
- How we’d reach the joints
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
FAQs for Mursley
Can you do external mastic in Mursley?
Yes, Mursley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Will you come out to Mursley?
Yes, Mursley is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do you seal joints where cladding meets other materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Landlords, agents and businesses in Mursley
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

What we’re called out for in Mursley
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
People normally contact us after spotting one of these:
- Failed seals between different materials
- Damp patches traced to an open external joint
- Joints where the bead has come unstuck
- Joints with sealant missing in places
If you let a flat or house near Bletchley station, split movement joints are easy to miss on a rental until damp shows inside.

- Are they insured?
- What the cure time is
- How long the guarantee is
What sealant work cannot fix
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Render & cladding joints
- Copings & trims
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Concrete & block
The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. For a village or hamlet like Mursley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Why act early in Mursley
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Where a wall is exposed, as many are in small places like Mursley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
