How we handle remedial sealant in Northwood
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. We work on shrunken worktop sealant, leaking tray & enclosure joints and botched or over-sealed joints, and common reasons people get in touch are wide, uneven beads that look worse than the old ones and black mould underneath the bead.
Somewhere as small as Northwood, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Our work is backed for twelve months.

Northwood questions
Is Northwood in your area for remedial sealant?
Yes, Northwood is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for hotels and guest houses in Northwood?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Is remedial work guaranteed?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
What if resealing won’t fix my leak?
Then we explain what we’ve found. You may need a plumber or bathroom fitter.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too in Northwood and across the Isle of Wight. Several sites can go on one quote, and we’re fully insured.
What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. In a small place like Northwood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Why it’s worth doing now in Northwood
Remedial work takes longer than a straight reseal, but rarely a lot: the work takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. In a small place like Northwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before we start.
What you get with us
- A sealant colour to suit the surroundings
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas
- 180+ five-star Google reviews
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
Remedial sealant around Northwood
Northwood is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. There are hotels and other places to stay in and around Northwood. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
If you live in an older home near All Saints' Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Northwood Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, 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.
