DIY versus a professional finish
If you are 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 doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How we handle remedial sealant in Highfield
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. We work on failed movement joints, expansion joints and leaking tray & enclosure joints, and people most often call us about movement joints that have split or pulled away and thick, messy sealant smeared over tiles.
In a smaller place like Highfield, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Highfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Advice
Landlords, agents and businesses in Highfield
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Do you need remedial sealant in Highfield?
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
It’s worth asking for a quote if you see:
- Sealant that came away because the surface wasn’t prepared
- Dark patches showing through the sealant
- Repeat leaks from the same joint
- Torn expansion joints
Homes close to Highfield Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

How the job changes by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Leave it or put it right?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a smaller place like Highfield, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep the room well ventilated
- Do not wait for a small gap to become a leak
- Get the cause of a repeat leak found before resealing
- Always have old sealant cut out, not covered
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Remedial sealant in Highfield: local notes
Highfield is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Highfield has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Managing a site like Highfield Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near St Denys station, a joint that keeps failing is best fixed properly while the property is empty.

Will you come out to Highfield?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What do you put in the joint?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
