About our remedial sealant in Borehamwood
Remedial jobs in Borehamwood generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. If you have gaps opening along the back of the worktop and over-sealed joints coming away, we can help, on mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant alike.
Around Borehamwood, it’s mostly busy family bathrooms and kitchens, where sealant and grout take a lot of daily wear. The usual signs are mould in the bead, gaps by the sink and grout that’s cracked or stained.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Have loose fittings fixed before resealing
- Use a soft cloth, not a scourer, on silicone
- Never seal over old silicone
- Get the cause of a repeat leak found before resealing
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Do you need remedial sealant in Borehamwood?
Movement tears sealant that isn’t designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
The most common problems we see are:
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
For landlords with property near Elstree & Borehamwood station, botched sealant from a previous quick fix is easier to strip out between tenants.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. A visit in Borehamwood needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules

- Any working-time requirements on site
- The size of the job

What guarantee comes with remedial sealant in Borehamwood?
All our work, in Borehamwood and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
Are you fully insured?
Yes, we are fully insured for every job we do.
What if resealing won’t fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Surface by surface
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal with a low-modulus product.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before any new sealant goes on.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
