External mastic in Maids Moreton
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We’re often asked to deal with weathered mastic that no longer stretches and rain getting behind render or cladding at a joint, across copings & trims, render & cladding joints and joints between brick and frames.
Somewhere as small as Maids Moreton, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, you get the same 12-month guarantee in Maids Moreton and across Buckinghamshire.

What we’re called out for in Maids Moreton
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
It’s worth asking for a quote if you see:
- Joints where the bead has come unstuck
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Weeds or debris growing in open joints
Homes close to Church of St Edmund include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Whether all the old sealant comes out first
- The length of the guarantee
- Is VAT in the price?
- Are they insured?
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we can’t put right
In fairness, there are a few things sealant won’t fix:
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer
- Loose or hollow render, which needs re-rendering
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Copings & trims
- Concrete & block
- Render & cladding joints
What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. In a small place like Maids Moreton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Why it’s worth doing now in Maids Moreton
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like Maids Moreton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Your questions about external mastic in Maids Moreton
Is Maids Moreton within the area you cover?
Yes, Maids Moreton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Maids Moreton for external mastic?
Yes. We work across London and the South East, and Maids Moreton is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose and can lead to cracking. A flexible sealant is the right fill.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Looking after it afterwards
To keep the joints looking good and working properly:
- Act on the first splits you see
- Leave the joints unpainted unless we’ve said otherwise
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

Maids Moreton buildings and the weather
The South East is one of 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 Stowe House (about 2.3 miles north-west) nearby, there’s older building stock in the area around Maids Moreton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Maids Moreton Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
