How we handle remedial sealant in Hamstreet
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you ring 0345 464 0079 or send us an email, and say how long ago it was last done. We work on expansion joints, failed movement joints and botched or over-sealed joints, and people most often call us about gaps opening along the back of the worktop and movement joints that have split or pulled away.
In a village or hamlet like Hamstreet, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t add new sealant on top of old
- Keep bleach and abrasives off the bead
- Run the fan after every shower
- Check ceilings under showers for marks
Don’t let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. In a small place like Hamstreet, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Hamstreet homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of the Good Shepherd, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Ham Street station, a joint that keeps failing is best fixed properly while the property is empty.

Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Hamstreet can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Different surfaces, different methods
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Your questions about remedial sealant in Hamstreet
Will you come out to Hamstreet?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Ham Street station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Hamstreet.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
