Hudnall questions
Is Hudnall in your area for remedial sealant?

Can you help a landlord with a rental near Berkhamsted station?

How long will it take to strip and reseal the joint?
The number of joints and layers decides it. You will have a timescale before any work begins.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee, and we are ARBOMaster approved.
How we handle remedial sealant in Hudnall
Some sealant jobs are not 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’re dealing with black mould underneath the bead and worktop sealant that has shrunk and split, we can put it right, whatever the surface.
In a village or hamlet like Hudnall, 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.
Each job carries a 12-month guarantee, whatever its size.

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many layers have to come out in most cases.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How to look after the new joints
So the new joints stay in good condition:
- Always have old sealant cut out, not covered
- Do not point over movement joints
- Look for stains below bathrooms now and then
- Get the cause of a repeat leak found before resealing
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.

Surface by surface
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.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
Common problems we fix in Hudnall
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
People generally contact us after spotting something like this:
- Wide, uneven beads that look worse than the old ones
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
- Floor or wall movement joints that have failed
If you let a flat or house near Berkhamsted station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
