Tonwell questions

Can you do commercial sealant in Tonwell?

Yes, Tonwell is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.

I let a flat near Ware station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

Where are you based?

We work from Crawley. Our applicators cover Tonwell, along with the rest of our area.

What does commercial sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Does someone need to be in?

Access is agreed with you when the job is booked. Indoors, that normally means someone at home.

When can guests or staff use the shower again?

It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.

Can you reseal hotel rooms while we stay open?

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.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

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.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

How the job changes by surface

Welfare facilities

Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone, including accessible wet rooms.

Student & care accommodation

Many accommodation blocks have rows of similar en suites. A room-by-room programme keeps the job efficient.

Why it’s worth doing now in Tonwell

A quick bead over the old sealant might get a room back in use today, but it will not bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. In a small place like Tonwell, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

How it works

At the end, we look at the finished work together and explain the cure time. The work normally takes a morning for a small washroom, and a planned programme for bigger sites, depending on the size of the job. Somewhere like Tonwell needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Rooms are handed back in order, each with its cure time.

Getting ready for the visit

  • Move anything stored near the joints
  • On commercial sites, let us know about site rules
  • Tell us about any water getting in

Advice

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Check the joints during routine room inspections
  • Keep a record of which rooms were resealed and when
  • Report broken fans quickly
  • Schedule work around occupancy

Include sealant in routine room inspections. Checking joints alongside other room checks catches failures before they leak.

Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Water coming from plumbing rather than sealant
  • Certifying fire stopping or building compliance
  • Poor ventilation that keeps bringing mould back

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
