Remedial sealant in New Denham
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We are often asked to deal with torn expansion joints and sealant peeling off a dusty or damp surface, across leaking tray & enclosure joints, mouldy bath & shower sealant and expansion joints.
Homes around New Denham are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
You get a one-year guarantee, the same in New Denham as everywhere else we work.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like New Denham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us if parking is tricky

Questions from New Denham
I let a flat near Denham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to New Denham?
Yes, New Denham is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you strip sealant from an acrylic tray safely?
Yes. We avoid heavy scraping and use the right cleaner for each surface, so the new sealant bonds cleanly.
What if resealing won’t fix my leak?
Then we explain what we have found. You may need a plumber or bathroom fitter.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Do I have to be there?
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.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that’s cracked
- Water damage behind tiles that needs a tiler
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
Aftercare tips
A little care helps the new joints last. Our advice:
- Keep the room well ventilated
- Ask why a joint failed before redoing it
- Clean sealant with mild products only
- Do not point over movement joints
Give the new sealant its full cure time: follow the cure time we give you.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.

What affects the quote in New Denham
Your quote is based on your job. We take into account:
- Access and height
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Which sealant suits the joint
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
You do not need to know the technical terms. Just tell us:
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Why deal with it now?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we’ll tell you. Around New Denham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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. We give a clear quote before we start.
Why us?
- Approved under the ARBOMaster scheme
- We never seal over old sealant
- Anti-fungal silicone where joints get wet
- Over 20 years’ experience

What remedial sealant looks like in New Denham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St Francis, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Managing a site like Hermitage Primary School? Then 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. Rented homes near Denham station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
