Commercial sealant in Brentwood

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Put a squeegee in each shower
  • Log resealing so you know what’s due
  • Plan resealing around quiet periods
  • Check the joints during routine room inspections

Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.

Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.

Brentwood questions

Do you work for landlords with property near Brentwood station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.

Can you do commercial sealant in Brentwood?

Yes, Brentwood is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before resealing.

What should I tell you?

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

Can you do several jobs on one visit?

Yes. Just list everything you need and we’ll quote it together.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can you supply method statements and risk assessments?

We’re fully insured, so start by telling us what your site asks for. We’ll confirm what we can supply when we quote.

Can you take on a whole building?

Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Workplaces and buildings in Brentwood

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

For site and facilities teams at buildings such as Becket Keys Church of England School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Community buildings like Church of St Thomas of Canterbury are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

The process

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours per room, so whole buildings are phased, including the tidy-up. For a job in Brentwood, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Every area is sheeted and the old silicone stripped out.
  3. Joints are cleaned, treated for mould and dried.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Each room is checked and handed back with its cure time.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • Keep children and pets away from the work area
  • For business premises, tell us about site rules or sign-in

Related advice

What happens if it’s left?

In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. In a family home in Brentwood, a failed seal around a bath or a frame lets water into places you cannot see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.

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

  • Fire risk assessments or certification

  • Damaged sanitaryware that needs replacing

If in doubt, call 0345 464 0079 or email us and we will say what we think.
