External mastic for homes and businesses in Heart's Delight
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. We work on concrete & block, façade panels and render & cladding joints, and people most often call us about failed seals between different materials and moss and dirt in joints with no sealant left.
External sealant needs dry, clean surfaces, so work around Heart's Delight is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Questions from Heart's Delight
Do you cover smaller places like Heart's Delight?
Yes, Heart's Delight is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Snowdown station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges, and reseal at that point.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
What is backing rod for?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Signs you need external mastic in Heart's Delight
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
It’s worth asking for a quote if you see:
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
If you let a flat or house near Snowdown station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Which sealant they’ll use, and why
- The length of the guarantee
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
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.
Heart's Delight buildings and the weather
Historic houses like Acrise Place (about 4.4 miles south) are a reminder that the area around Heart's Delight has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Barham Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St John the Baptist, the joints between older walls, newer extensions and the roofline need a sealant that can move.

If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.

How to look after the new joints
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Older cottages and farmhouses around Heart's Delight can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Failed render or damaged cladding panels
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
