Trusted commercial sealant in Dartford

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Commercial sealant for homes and businesses in Dartford

Hotel bathrooms take hard daily use and constant cleaning, so sealant wears out faster than it would at home. Rooms are resealed in batches, so only a few are out of use at once. If you’re dealing with split sealant where wet room floors meet walls and mouldy bathrooms flagged at a tenancy check, we can put it right.

Shared washrooms take far more use than a home bathroom, and their sealant shows it, and fire-rated joints need restoring whenever new services are run through a wall. For a building in Dartford, we plan timings around how it’s used.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What we cannot put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Poor ventilation that keeps bringing mould back
  • Water damage behind the tiles that needs a tiler or builder
  • A shower tray, bath or basin that’s cracked or broken

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What we seal

  • Office washrooms & kitchens
  • Retail & leisure sites
  • Rental portfolios
  • Welfare facilities
  • Student & care accommodation
  • Hotel bathrooms

What happens on the day

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes as long as the scope needs, from one welfare room to a full building. Parking in a town like Dartford is normally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. We reseal with the right product for each joint.
  5. Rooms are handed back in order, each with its cure time.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before

How the job changes by surface

Student & care accommodation

Vacant rooms make resealing quick and simple, but occupied rooms can be planned in as well.

Rental portfolios

A sound seal protects the property as well as its appearance.

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. Doing it properly once is less disruptive than doing it badly twice. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.

What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Dartford questions

Is commercial sealant in Dartford guaranteed?

All our work, in Dartford and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Can you help a landlord with a rental near Dartford station?

Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you quote for more than one area?

Yes. Just list everything you need.

Can I choose the sealant colour?

We will suggest a colour to suit the surroundings. The product needed can limit the range.

Does someone need to be in?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Do the sealants smell?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

Can you seal over the old sealant?

No. The old sealant always comes out first, so the new sealant bonds properly.
