How we handle commercial sealant in Thornhill
Student halls, care homes and supported housing have many similar bathrooms. A room-by-room programme keeps the job organised, working around residents and staff routines. If you have silicone laid over old silicone by a previous contractor and mouldy washroom sealant that staff and guests notice, we can help, on student & care accommodation, hotel bathrooms and rental portfolios alike.
In a smaller place like Thornhill, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
Each job carries a 12-month guarantee, whatever its size.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Ask cleaners to go gently on the silicone
- Don’t leave a failed joint until the next refurbishment
- Include the silicone on your room checklists
- Encourage users to squeegee shower walls
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.

Leave it or put it right?
A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. One proper reseal beats several quick ones. In an older home around Thornhill, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Commercial sealant in Thornhill: local notes
For seaside hotels, guest houses and holiday lets around Thornhill, 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.
For buildings such as St Christopher, any kitchen and washrooms need the same sealant care as any other building. If you let a flat or house near Sholing station, several rental properties can be resealed on one programme. If you look after a building such as Thornhill Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

What affects the cost of commercial sealant
You’ll get a clear quote before any work starts. It takes into account:
- The old material and how stubborn it is
- How many areas need sealing
- The number and length of the joints

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Water damage behind the tiles that needs a tiler or builder
- Cracked trays or baths rather than failed joints
- Fire risk assessments or certification

Common questions in Thornhill
Do you cover Thornhill for commercial sealant?
Yes. Our work covers London and the South East, and Thornhill 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 quote.
Is Thornhill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Does commercial work come with a guarantee?
Yes. We give a 12-month guarantee on every job and are fully insured.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can you reseal hotel rooms while we stay open?
Generally, yes. We agree the room order and times with your managers, and you will know when each room can be used.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on the number of rooms, depending on the size of the job. A visit to Thornhill is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before we start.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
