What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many layers have to come out. Parking in a town like Egham is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Remedial sealant for homes and businesses in Egham
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We’re often asked to deal with products that weren’t meant for the joint and sealant peeling off a dusty or damp surface, on leaking tray & enclosure joints, mouldy bath & shower sealant and botched or over-sealed joints.
In a town like Egham, older streets sit alongside newer estates, so bathrooms range from long-standing suites to recent refits. Either way, the sealant and grout are normally the first things to fail.
Each job carries a 12-month guarantee, whatever its size.

What affects the quote in Egham
We do not publish a price list, because no two jobs are the same. What we look at:
- Whether the work is at height
- Working hours on commercial sites
- The old material and how stubborn it is
- Any mould that needs treating
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 we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The rough size of the job
- The address or postcode of the job
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Never seal over old silicone
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
- Clean sealant with mild products only
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Bathrooms and kitchens in Egham
There are hotels and other places to stay in and around Egham. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a building such as Manorcroft Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Egham station, botched sealant from a previous quick fix is easier to strip out between tenants.

What the job involves on each surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we’ll point out.

Other services in Egham
Do you need remedial sealant in Egham?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
These are the problems we are asked about most:
- Repeat leaks from the same joint
- Movement joints that have split or pulled away
- Wide, uneven beads that look worse than the old ones
- Over-sealed joints coming away
For an older house near a landmark such as St John's Church, walls and floors in older homes can move, and sealant and grout show it first.
