The process
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours, depending on how many layers have to come out. For a job in Cambridge Heath, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

About our remedial sealant in Cambridge Heath
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and common reasons people get in touch are torn expansion joints and black mould underneath the bead.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Cambridge Heath, remedial sealant is as much about a room looking cared for as about keeping water out.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Questions from Cambridge Heath
Do you work for landlords with property near Cambridge Heath station?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you take on hotel work around Cambridge Heath?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Is remedial work guaranteed?
Yes, with our 12-month guarantee. If we have pointed out another problem, getting it fixed helps the new joint last.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. For most joints, it’s a few hours, and we confirm the time with your quote.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Cambridge Heath homes and their sealant
There are hotels and other places to stay in and around Cambridge Heath. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings.
Homes close to St James-the-Less include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Letting a property close to Cambridge Heath station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Different surfaces, different methods
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
Do you need remedial sealant in Cambridge Heath?
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing sets the depth and stops that.
It’s worth asking for a quote if you see:
- Beads that never stuck properly
- Caulk or the wrong sealant used in a wet area
- Floor or wall movement joints that have failed
- Sealant applied over old sealant that has lifted
Cambridge Heath is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- The product the joint needs
- Mould in or behind the old joints
- The number of rooms or windows
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
What we need to know
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If someone has resealed it before
- How we’d reach the joints
We do not publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Cambridge Heath.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
