How the job changes by surface
Joints between dissimilar materials
Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.
Cladding and façade panels
Cladding and façade panels are normally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
External mastic for homes and businesses in Howegreen
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We work on joints between brick and frames, concrete & block and façade panels, and common reasons people get in touch are movement joints with cracked, split or missing sealant and sealant that has lost its bond to the brick or render.
External sealant needs dry, clean surfaces, so work around Howegreen is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

What else we do in Howegreen
Signs you need external mastic in Howegreen
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Keep an eye out for these signs:
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
Schools such as Purleigh Community Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- Is the old sealant removed completely?
- How the colour is chosen
- What the quote includes, VAT included or not
- What insurance they hold
Leave it or put it right?
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last. Around Howegreen, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- A sealant colour to suit the surroundings
- Sanitary silicone with an anti-fungal additive in wet areas
- Trusted Arbo and Everbuild sealants
- We are fully insured
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
- Structural movement, which needs a surveyor or engineer
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Render & cladding joints
- Joints between brick and frames
- Copings & trims
- Façade panels
- Brickwork movement joints
- Concrete & block
What external mastic looks like in Howegreen
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Danbury Place (about 4.9 miles north-west) nearby, there’s older building stock in the area around Howegreen as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Parish Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near North Fambridge station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Have failed joints looked at early
- Make sure movement joints are not pointed over
- Clear growth from the base of walls and joints
- Avoid pressure-washing directly into sealant joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Howegreen, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Tell us about any water getting in
How to get a quote

Advice
Your questions about external mastic in Howegreen
Will you come out to Howegreen?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Howegreen in your area for external mastic?
Yes. We work across London and the South East, and Howegreen is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
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.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
