Remedial sealant in Hampstead Norreys
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. If you have a second bead peeling off the first and sealant peeling off a dusty or damp surface, we can help.
In a village or hamlet like Hampstead Norreys, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Different surfaces, different methods
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When to call us in Hampstead Norreys
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
- Sealant applied over old sealant that has lifted
- Black mould underneath the bead
Homes close to Church of St Mary include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
What your quote should include
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- What product goes in the joint
- What the cure time is
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Hampstead Norreys, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Related advice
Leave it or put it right?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In a small place like Hampstead Norreys, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
