External mastic in Lillingstone Lovell
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on render & cladding joints, joints between brick and frames and façade panels, and people most often call us about rigid filler in a joint that should flex and hard, crazed mastic that has stopped moving.
Around Lillingstone Lovell, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in.
Each job carries a 12-month guarantee, large or small.

How the job changes by surface
Concrete and blockwork
Big joints in concrete need careful depth control. Backing rod sized to the joint sets it so the sealant isn’t too deep.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
Aftercare tips
So the new joints stay in good condition:
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

Lillingstone Lovell questions
Is Lillingstone Lovell within the area you cover?

Can you do external mastic in Lillingstone Lovell?
Yes, Lillingstone Lovell is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
How much does external mastic cost in Lillingstone Lovell?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Lillingstone Lovell.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Why it’s worth doing now in Lillingstone Lovell
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Lillingstone Lovell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. In a small place like Lillingstone Lovell, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Clear the area around the work
