- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
- Dark patches showing through the sealant
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Haultwick, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
Getting a quote
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

Remedial sealant in Haultwick
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. If you’re dealing with smears and lumps from a botched reseal and over-sealed joints coming away, we can help, whatever the surface.
Somewhere as small as Haultwick, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

Landlords, agents and businesses in Haultwick
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams in Haultwick and across Hertfordshire. Several sites can go on one quote.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Where we work in Haultwick

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Ask why a joint failed before redoing it
- Always have old sealant cut out, not covered
- Clean sealant with mild products only
- Keep the room well ventilated
Keep the room ventilated: use the extractor or open a window after showering.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Different surfaces, different methods
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
How we quote for remedial sealant
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- How much there is to do
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- If someone has resealed it before
- The problem you’ve noticed
- Roughly how big the job is
- How we’d reach the joints
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
Remedial sealant around Haultwick
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
In the older streets around Parish Church of All Saints, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Watton-At-Stone station? Then botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Munden Church of England Voluntary Controlled Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
