Remedial sealant in Chalkhouse Green
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. Common call-outs are for sealant that came away because the surface wasn’t prepared and gaps opening along the back of the worktop, across botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints.
Around Chalkhouse Green, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- A bath, tray or worktop that moves until it’s properly fixed
- Failed tanking or loose tiles behind the sealant
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

What remedial sealant looks like in Chalkhouse Green
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Reading station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Emmer Green Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Saint Barnabas Emmer Green include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What the job involves on each surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We’ll tell you what we find.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Always have old sealant cut out, not covered
- Never fill a movement joint with mortar or grout
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
Do not let anyone seal over it later. New silicone doesn’t bond to old.
Do not keep resealing the same joint. Have someone find out why, or the next bead will go the same way.

Your questions about remedial sealant in Chalkhouse Green
Do you cover smaller places like Chalkhouse Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Chalkhouse Green in your area for remedial sealant?
Yes, Chalkhouse Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How long before the joint can be used?
Cure times vary by product and the conditions. Before we leave, we will tell you the cure time.
Is remedial work guaranteed?
Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Why it’s worth doing now in Chalkhouse Green
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Chalkhouse Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
