What affects the cost of remedial sealant
Your quote is based on your job. We look at:
- Working hours on commercial sites
- The type of sealant required
- Whether there’s mould to deal with
- How many areas need sealing
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
When you call or email, it’s useful to know:
- Where the job is, and your postcode
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
For a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. We can quote a run of properties together.
What happens if it’s left?
Remedial work takes longer than a straight reseal, but not by much: the work takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Highsted, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

The process
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. For a village or hamlet like Highsted, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Highsted questions
Do you cover smaller places like Highsted?

I let a flat near Sittingbourne station. Can you help?

What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Highsted homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. There are hotels and other places to stay in and around Highsted. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as Church of St Nicholas, walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Sittingbourne station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Around Highsted

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
So the new joints stay in good condition:
- Never seal over old silicone
- Do not point over movement joints
- Act on a lifting corner straight away
- Keep an eye on the ceiling below the bathroom
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Signs you need remedial sealant in Highsted
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
The problems people generally mention when they call include:
- Worktop sealant that has shrunk and split
- Thick, messy sealant smeared over tiles
- Torn expansion joints
- Dark patches showing through the sealant
Managing a site like Rodmersham School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
