When something else is needed
To be straight with you, some problems need a different trade:
- Movement from fittings that are not supported
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Remedial sealant for homes and businesses in Calvert
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. Typical jobs include dark patches showing through the sealant and a shower that leaks however often it’s resealed, on leaking tray & enclosure joints, mouldy bath & shower sealant and failed movement joints.
Being in a small place like Calvert makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re 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.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Deal with small splits early
- Use a soft cloth, not a scourer, on silicone
- Do not add new sealant on top of old
- Get the cause of a repeat leak found before resealing
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. In a small place like Calvert, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Common problems we fix in Calvert
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Look out for these signs:
- Repeat leaks from the same joint
- Dark patches showing through the sealant
- Torn expansion joints
- Worktop sealant that has shrunk and split
For an older house near a landmark such as Church of St Michael, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- How much experience the applicator has
- What product goes in the joint
- What happens if the job turns out different
- Whether they seal over old material or remove it
How the job changes by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.
Calvert homes and their sealant
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.
In and around Calvert, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

What happens if it’s left?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Where a wall is exposed, as many are in small places like Calvert, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
