About our commercial sealant in Gunville
With over 20 years in sealant work, we are a fully insured, ARBOMaster approved team. If your site needs RAMS or insurance details, tell us, and we will confirm what we can supply with the quote. Typical jobs include large numbers of bathrooms needing the same work and mouldy washroom sealant that staff and guests notice, across student & care accommodation, hotel bathrooms and retail & leisure sites.
If you have holiday lets, a converted barn used for business or a community building near Gunville, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Signs you need commercial sealant in Gunville
Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.
The problems people normally mention when they call include:
- Leaking joints in shower rooms and changing areas
- Split sealant around staff kitchen worktops and sinks
- Leaks from showers into rooms or ceilings below
- Whole floors of tired en suites
Managing a site like Carisbrooke College? Then busy washrooms and kitchens can be resealed in phases so they stay open.

What happens if it’s left?
Sealant work is quick by the room: the job takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Older cottages and farmhouses around Gunville can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.

Gunville: your questions answered
Do you work in hotels near Gunville?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you cover Gunville for commercial sealant?
Yes. Our work covers London and the South East, and Gunville is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
What does commercial sealant cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you reseal between tenancies?
Yes, we can. Send us the addresses and what needs doing, and we’ll give you a clear quote.
How long will you be here?
Typically it takes a few hours per room, so whole buildings are phased. Larger jobs naturally take longer, and we will say how long yours will take.

Commercial buildings in Gunville
There are hotels and other places to stay in and around Gunville. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a church, hall or community building such as St. Mary's Church, any kitchen and washrooms need the same sealant care as any other building.

How it works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours per area, with larger sites planned over several visits. Somewhere like Gunville needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the rooms and agreeing what’s needed.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
Aftercare tips
So the new joints stay in good condition:
- Add sealant to your planned maintenance checks
- Get split or lifting joints looked at early
- Log resealing so you know what’s due
- Keep extractor fans working and serviced
Extract fans need to work. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.
Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
