Warmlake External Mastic
We cover Warmlake for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Damp patches traced to an open external joint
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
About our external mastic in Warmlake
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’ll confirm what’s needed to reach them safely. Typical jobs include joints with sealant missing in places and rain getting behind render or cladding at a joint, on façade panels, brickwork movement joints and concrete & block.
Somewhere as small as Warmlake, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a 12-month guarantee.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- The old material and how stubborn it is
- Any mould that needs treating
- The size of the job
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 make a difference, and we’ll explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- Any previous sealing or DIY work

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Avoid pressure-washing directly into sealant joints
- Do not let climbing plants root in the sealant
- Walk round the building once a year and look at the joints
- Get split or bare joints resealed while the damage is small
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.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Adding movement joints to masonry that has none
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Warmlake buildings and the weather
With historic houses such as Stoneacre (about 2.1 miles north) nearby, there’s older building stock in the area around Warmlake 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Hollingbourne station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Schools such as Sutton Valence Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Warmlake: your questions answered
Do you cover smaller places like Warmlake?

Yes, Warmlake is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
I rent my home. Can I book you?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Landlords, agents and businesses in Warmlake
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.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Do you need external mastic in Warmlake?
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
People usually contact us when they notice one of these:
- Damp patches traced to an open external joint
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
- Sealant pulling away from one side of the joint
Homes close to Church of St Michael include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

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, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Warmlake needs a little journey planning: 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
