Remedial sealant & repairs in Downham, Essex
Removing failed, mouldy or leaking sealant and putting it right for homeowners, landlords and businesses in Downham. Fully insured, ARBOMaster approved and guaranteed for a year.
- Black mould underneath the bead
- Torn expansion joints
- Sealant peeling off a dusty or damp surface
What happens if it’s left?
Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. In a small place like Downham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

How we handle remedial sealant in Downham
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you are dealing with kitchen joints letting water behind the worktop and floor or wall movement joints that have failed, we can help.
Homes around Downham are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
All our work is covered by a 12-month guarantee, wherever you are in Essex.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Never fill a movement joint with mortar or grout
- Look for stains below bathrooms now and then
- Run the fan after every shower
- Don’t wait for a small gap to become a leak
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just ring 0345 464 0079 or email us.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Bathrooms and kitchens in Downham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as The Bromfords School and Sixth Form College, 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. If you let a flat or house near Wickford station, a joint that keeps failing is best fixed properly while the property is empty.

Do you need remedial sealant in Downham?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
If you can see any of these, it’s time to have the joints looked at:
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
For an older house near a landmark such as Church of St Margaret, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Questions to ask before you book
- Which colour the sealant will be
- How long to leave it before use
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
