Remedial sealant & repairs in St Paul's Walden, Hertfordshire
Professional remedial sealant in and around St Paul's Walden, with every bit of old sealant taken out first.
- Repeat leaks from the same joint
- Floor or wall movement joints that have failed
- Sealant peeling off a dusty or damp surface
Aftercare tips
To keep the joints looking good and working properly:
- Check trays and worktops do not move
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
- Do not wait for a small gap to become a leak
Clean gently: no scraping, scouring pads or harsh chemicals.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
About our remedial sealant in St Paul's Walden
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have wide, uneven beads that look worse than the old ones and leaks that keep coming back after resealing, we can put it right.
Somewhere as small as St Paul's Walden, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All our work is covered by our one-year guarantee.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What remedial sealant looks like in St Paul's Walden
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Homes close to All Saints Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Stevenage station, botched sealant from a previous quick fix is easier to strip out between tenants.

What happens if it’s left?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Where a wall is exposed, as many are in small places like St Paul's Walden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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.

What we can’t put right

Quotes for remedial sealant in St Paul's Walden
There’s no set price list, because jobs vary so much. The quote depends on:

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What we are called out for in St Paul's Walden
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
Any of these means the joints need attention:
- Torn expansion joints
- Kitchen joints letting water behind the worktop
- A second bead peeling off the first
- Black mould underneath the bead
For site and facilities teams at buildings such as St Paul's Walden Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- What product goes in the joint
- Who does the work, and how experienced they are
- When the joint can take water or movement
- What guarantee comes with the work
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like St Paul's Walden, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- 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
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
