Commercial sealant for homes and businesses in St Mary's
In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on student & care accommodation, retail & leisure sites and office washrooms & kitchens, and common reasons people get in touch are worktop sealant that has shrunk and stained and washrooms that need sorting before an inspection.
Commercial work around a smaller place like St Mary's normally means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Certifying fire stopping or building compliance
- Cracked trays or baths rather than failed joints
- Water coming from plumbing rather than sealant

Workplaces and buildings in St Mary's
For seaside hotels, guest houses and holiday lets around St Mary's, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.
Managing a site like Hope Community School Southampton? Then washroom and kitchen sealant can be programmed around term times or opening hours. Rented homes near Southampton Central station change hands often, and several rental properties can be resealed on one programme. If you look after a church, hall or community building such as St Mary's Church, halls and community kitchens see heavy use, and their sealant shows it.

- The number of rooms or windows
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
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.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes as long as the scope needs, from one welfare room to a full building and we leave things clean and tidy. Parking around St Mary's is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start with a site walk to agree the rooms and the timing.
- Every area is sheeted and the old silicone stripped out.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
St Mary's questions
Do you work in hotels near St Mary's?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Southampton Central station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
When can guests or staff use the shower again?
Follow the cure time we give you, which is usually around 24 hours. Planning the order of rooms keeps that downtime manageable.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Book larger programmes for quieter times of year
- Put a squeegee in each shower
- Note the date each area was done
- Get split or lifting joints looked at early
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
