How we quote for remedial sealant
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- How easy the joints are to reach
- The number of rooms or windows
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Common questions in Crumbles
Is Crumbles within the area you cover?
Yes, Crumbles is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Crumbles for remedial sealant?
Yes. We work across London and the South East, and Crumbles is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
How do I get a quote for remedial sealant in Crumbles?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
How long does the work take?
The number of joints and layers decides it. We’ll tell you before work begins.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Crumbles and the rest of East Sussex.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What else we do in Crumbles
Do you need remedial sealant in Crumbles?
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Look out for these signs:
- Thick, messy sealant smeared over tiles
- Black mould underneath the bead
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
Schools such as St Catherine's College are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
Before you book anyone
- Who turns up on the day
- Is VAT in the price?
- Which colour the sealant will be
- Are they insured?
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What happens if it’s left?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Crumbles can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- A sealant colour to suit the surroundings
- You choose the colour before work begins
- Sanitary silicone with an anti-fungal additive in wet areas
- Over 20 years’ experience

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Crumbles, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

What remedial sealant looks like in Crumbles
Crumbles is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. 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.
In the older streets around St. Richard, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Rented homes near Pevensey & Westham station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
Crumbles is about 2 miles east of Eastbourne, in East Sussex.

Aftercare tips
So the new joints stay in good condition:
- Keep an eye on the ceiling below the bathroom
- Don’t wait for a small gap to become a leak
- Keep the room well ventilated
- Ask why a joint failed before redoing it
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, ring 0345 464 0079 or send us an email.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
