Remedial sealant for homes and businesses in Hollingbury
In Hollingbury, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. If you have kitchen joints letting water behind the worktop and sealant peeling off a dusty or damp surface, we can put it right, on botched or over-sealed joints, expansion joints and shrunken worktop sealant alike.
In a smaller place like Hollingbury, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Big or small, it’s backed by our one-year guarantee in Hollingbury and across Brighton and Hove.

Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t wait for a small gap to become a leak
- Never seal over old silicone
- Have loose fittings fixed before resealing
- Keep the room well ventilated
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Hollingbury questions
Will you come out to Hollingbury?
Yes, Hollingbury is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Moulsecoomb station. Can you help?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Quotes for remedial sealant in Hollingbury
Your quote is based on your job. We take into account:
- Working hours on commercial sites
- The product the joint needs
- The old material and how stubborn it is
- The number of rooms or windows
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Asking for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.
What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. For a job in Hollingbury, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
How to get a quote
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.
Advice
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Bathrooms and kitchens in Hollingbury
Hollingbury is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. 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.
If you look after a building such as Carden Nursery and Primary School, 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 Moulsecoomb station, a joint that keeps failing is best fixed properly while the property is empty.

Why it’s worth doing now in Hollingbury
Mould under a bead cannot be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. In a smaller place like Hollingbury, 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.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.
