Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Older cottages and farmhouses around Cross-at-Hand can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

External mastic for homes and businesses in Cross-at-Hand
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you have cracked joints where brick meets render or frames and panel joints letting water in, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Cross-at-Hand is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

FAQs for Cross-at-Hand
Can you do external mastic in Cross-at-Hand?
Yes, Cross-at-Hand is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Is Cross-at-Hand within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Where are you based?
Mr Mastic is based in Crawley. We cover Cross-at-Hand and the rest of Kent.
Quotes for external mastic in Cross-at-Hand
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- The size of the job
- The product the joint needs
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- The rough size of the job
- The problem you’ve noticed
- Where the job is, and your postcode

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
When to call us in Cross-at-Hand
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
Look out for these signs:
- Damp patches traced to an open external joint
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Old sealant gone brittle and cracked
Rented homes near Staplehurst station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
What to look for in a quote
- Whether they seal over old material or remove it
- Whether you can choose the colour
- The length of the guarantee
- How much experience the applicator has

Looking after it afterwards
Aftercare is simple:
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
- Leave the joints unpainted unless we have said otherwise
- Deal with leaking gutters that soak the joints below
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
