How we handle remedial sealant in Cowley
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. If you have gaps opening along the back of the worktop and products that weren’t meant for the joint, we can help, on shrunken worktop sealant, botched or over-sealed joints and expansion joints alike.
Hard London water leaves limescale on sealant, grout and taps alike. In Cowley, remedial sealant is as much about a room looking cared for as about keeping water out.
All our work comes with our 12-month guarantee.

Questions from Cowley
Can you help a landlord with a rental near West Drayton station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you take on hotel work around Cowley?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that is already there.
Are you fully insured?
Yes. We are fully insured.
Bathrooms and kitchens in Cowley
London’s water is hard, so limescale builds up on sealant, grout and fittings. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
For an older house near a landmark such as Church of St Laurence, older homes can move a little, which is hard on rigid grout and tired sealant. Cowley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- The product the joint needs
- Mould in or behind the old joints
- When we can work, for business premises
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Any previous sealing or DIY work
- The address or postcode of the job
- The type of property
- Any access issues, like height or stairs
For remedial sealant in Cowley, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Cowley. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- 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
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

Advice
Different surfaces, different methods
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing stops that, so the sealant grips the two sides only.

What else we do in Cowley
Do you need remedial sealant in Cowley?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
The problems people normally mention when they call are:
- Kitchen joints letting water behind the worktop
- Movement joints that have split or pulled away
- Beads that never stuck properly
- Smears and lumps from a botched reseal
Letting a property close to West Drayton station? Then botched sealant from a previous quick fix is easier to strip out between tenants.
What to look for in a quote
- What guarantee comes with the work
- Whether they’re fully insured
- How hidden problems are handled
- Whether you can choose the colour
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Act on a lifting corner right away
- Have loose fittings fixed before resealing
- Never seal over old silicone
- Keep the room well ventilated
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Honest limits
To be straight with you, some problems need a different trade:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- A tray or bath that is cracked
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
