About our commercial sealant in Hendon

In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Typical jobs include tired sealant in let properties and washroom sealant that looks dirty however often it’s cleaned, on welfare facilities, office washrooms & kitchens and retail & leisure sites.

In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Hendon, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.

Whatever the size of the job, you get the same 12-month guarantee.

Hendon questions

Can parking be tricky for a visit in Hendon?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

How long does commercial sealant take?

Most jobs take as long as the scope needs, from one welfare room to a full building, including the preparation. Your quote will say how long we expect yours to take.

Will you leave a mess?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

Do you come to Hendon?

Yes, we do. Our applicators work in Hendon, and the service is the same as everywhere else.

Do you provide RAMS?

Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we’ll confirm what we can provide when we quote.

When something else is needed

A few problems are outside what sealant work can do:

  • Extraction that isn’t working, which needs an electrician or ventilation contractor
  • Tiles coming off the wall
  • Certifying fire stopping or building compliance

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

  • Office washrooms & kitchens
  • Student & care accommodation

What we do, step by step

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the number of rooms, including the tidy-up. In a London area like Hendon, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Each area is protected and the old sealant cut out completely.
  3. Joints are cleaned, treated for mould and dried.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Each room is checked and handed back with its cure time.

Getting ready for the visit

  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children
  • Try not to wet indoor joints just before the visit

Advice

What commercial sealant looks like in Hendon

London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Hendon. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a church, hall or community building such as Christ Church Hendon, halls and community kitchens see heavy use, and their sealant shows it. For landlords with property near Hendon station, sealant work can be quoted for a single flat or a whole portfolio. Hendon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

For landlords and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

How the job changes by surface

Student & care accommodation

In care settings, we agree the order and timings with staff, with each bathroom handed back with its cure time.

Hotel bathrooms

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

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Keeping the joints in good condition

Simple care keeps the joints in good condition. Our advice:

  • Pass on the cure time to whoever cleans the rooms
  • Keep strong chemicals and scourers off the joints
  • Report broken fans quickly
  • Act on lifting sealant before it leaks

Add sealant checks to your planned maintenance. 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.
