About our commercial sealant in Howe Hill
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we’ll confirm what we can supply with the quote. We work on retail & leisure sites, office washrooms & kitchens and welfare facilities, and common reasons people get in touch are joints that need doing before an inspection or audit and failed floor-level joints in accessible wet rooms.
If you have holiday lets, a converted barn used for business or a community building near Howe Hill, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Leave squeegees in busy showers
- Give housekeeping the cure time for every room
- Keep strong chemicals and scourers off the joints
- Log resealing so you know what’s due
Add sealant checks to your planned maintenance. A quick look at each bathroom when rooms are checked spots problems early.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Poor ventilation that keeps bringing mould back
- Damaged sanitaryware that needs replacing
- Certifying fire stopping or building compliance
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Quotes for commercial sealant in Howe Hill
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The number and length of the joints
- Whether the work is at height
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. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work

- The address or postcode of the job
- Photos by email, if that’s easy

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take as long as the scope needs, from one welfare room to a full building. In a small place like Howe Hill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises

Rental portfolios
An empty property is easy to reseal, ready for the next tenant.
Hotel bathrooms
We work through hotel rooms in agreed batches, keeping most of the hotel open. Housekeeping get a cure time for each room.
Leave it or put it right?
Room by room, the work is quick: it takes as long as the scope needs, from one welfare room to a full building. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. Older cottages and farmhouses around Howe Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.

Your questions about commercial sealant in Howe Hill
Do you cover smaller places like Howe Hill?
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.
Is commercial sealant in Howe Hill guaranteed?
All our work, in Howe Hill and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you work outside opening hours?
Often, yes. Tell us your opening hours and quiet times, and we’ll plan the work around them.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you send RAMS and insurance details for our site?
Tell us what paperwork your site needs, such as method statements, risk assessments or insurance details, and we’ll confirm what we can supply with the quote.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Can you work around guests in a hotel?
Yes. Rooms are done a few at a time, so only a few are out of use at once. Each room comes back with its cure time for housekeeping.
How soon can a room be used after resealing?
Plan for around 24 hours, or the cure time we give for that area. Planning the order of rooms keeps that downtime manageable.
