How to look after the new joints

A little care helps the new joints last. Our advice:

  • Add sealant to your planned maintenance checks
  • Schedule work around occupancy
  • Give housekeeping the cure time for every room
  • Keep a record of which rooms were resealed and when

Add sealant checks to your planned maintenance. A quick look at each bathroom when rooms are checked spots problems early.

Mould in shared washrooms gets noticed and talked about. The longer it’s left, the deeper it grows into the silicone, and only replacement fixes it.

What commercial sealant looks like in Kemsing

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

If you look after a church, hall or community building such as Church of St Mary, any kitchen and washrooms need the same sealant care as any other building. Rented homes near Otford station change hands often, and several rental properties can be resealed on one programme.

Landlord and commercial work in Kemsing

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What happens if it’s left?

A leaking shower in a hotel room or flat above can damage the ceiling below. Then two rooms are out of action, not one. A reseal now avoids that. Homes in smaller places like Kemsing can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Can I do it myself?

A careful DIYer can reseal a simple joint, 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.

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.

FAQs for Kemsing

Do you cover smaller places like Kemsing?

Yes, Kemsing is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do commercial sealant in Kemsing?

Yes, Kemsing is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Can new sealant go over the old?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Can you start early or work out of hours?

Early starts and out-of-hours work can be arranged. Tell us what you need when you ask for a quote.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

How do I get a quote for commercial sealant in Kemsing?

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.

When to call us in Kemsing

Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. A tray that is not fully supported soon tears its seal.

It’s worth asking for a quote if you see:

  • Whole floors of tired en suites
  • Mouldy washroom sealant that staff and guests notice
  • Mouldy bathrooms flagged at a tenancy check
  • Water marks on ceilings under bathrooms

Managing a site like Kemsing Primary School? Then washroom and kitchen sealant can be programmed around term times or opening hours.

Before booking anyone

  • What happens if the job turns out different
  • Who does the work, and how experienced they are
  • Which colour the sealant will be
  • When the joint can take water or movement

10 questions to ask before you book

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.

Hotel bathrooms

Hotel showers and baths get used and cleaned every day, so joints are finished smooth and sealed with anti-fungal sanitary silicone.

The process

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on the number of rooms. A visit to Kemsing is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  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. 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

  • Mention any sign-in or site rules at work premises
  • Let us know if you’ve seen damp or leaks
  • Mention any parking rules near the property
