Remedial sealant for homes and businesses in Broomfield
In Broomfield, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you are dealing with gaps opening along the back of the worktop and wide, uneven beads that look worse than the old ones, we can help.
In and around Broomfield, older properties sit alongside newer ones. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
There’s a 12-month guarantee on every job, whatever its size.

The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Broomfield, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Advice
What the job involves on each surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, and then we reseal it neatly.
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 so the new sealant starts clean.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Use a soft cloth, not a scourer, on silicone
- Ask why a joint failed before redoing it
- Keep movement joints clear of mortar and paint
- Have loose fittings fixed before resealing
Clean gently: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Why act early in Broomfield
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a smaller place like Broomfield, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What remedial sealant looks like in Broomfield
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of St Mary the Virgin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Chelmer Valley High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Broomfield: your questions answered
Is Broomfield in your area for remedial sealant?
Yes. Our work covers London and the South East, and Broomfield is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Broomfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What if resealing won’t fix my leak?
Then we explain what we have found. You may need a plumber or bathroom fitter before any new sealant goes on.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
How do I get a quote for remedial sealant in Broomfield?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or email us with a short description of the job.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Common problems we fix in Broomfield
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. None of them last.
Keep an eye out for any of the following:
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
- Floor or wall movement joints that have failed
For landlords with property near Beaulieu Park station, a joint that keeps failing is best fixed properly while the property is empty.
