Need commercial sealant in Southgate?

Surface by surface

Hotel bathrooms

We work through hotel rooms in agreed batches, so most rooms stay available. Housekeeping get a cure time for each room.

Retail & leisure sites

Gym and leisure changing rooms take heavy use and plenty of water, so joints are sealed with anti-fungal sanitary silicone.

Commercial sealant in Southgate, done properly

In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We work on hotel bathrooms, rental portfolios and office washrooms & kitchens, and the jobs we see most are sealant failing again soon after quick repairs and large numbers of bathrooms needing the same work.

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

A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens on the day

We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes a morning for a small washroom, and a planned programme for bigger sites. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Southgate. It helps if you can point us to a visitor permit or a bay close to the door.

  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. We reseal with the right product for each joint.
  5. Each finished area is checked with you and given a cure time.

How to prepare

  • Clear items away from the joints we’re working on
  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules

FAQs for Southgate

Can you help a landlord with a rental near New Southgate station?

Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Do you work in hotels near Southgate?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

How much does commercial sealant cost in Southgate?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

Can you seal over the old sealant?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do I need to be at home?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.

Can you send RAMS and insurance details for our site?

Tell us what your site asks contractors for. We’ll confirm what we can supply before work is booked.

Can I do it myself?

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

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Quotes for commercial sealant in Southgate

The price is agreed before any work begins. It’s based on:

  • Working hours on commercial sites
  • The product the joint needs
  • How much there is to do
  • Any mould that needs treating

A few things move the cost up or down: 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.

What we need to know

When you call or email, these details help:

  • The rough size of the job
  • How we’d reach the joints
  • If someone has resealed it before
  • The address or postcode of the job

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.

Why act early in Southgate

Room by room, the work is quick: it takes a few hours per area, with larger sites planned over several visits. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Southgate, the repair is bigger than the sealant job would have been.

What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Why book with us

  • ARBOMaster approved applicator
  • Any old sealant cut out fully, not covered over
  • White, clear, grey or another colour, product permitting
  • Anti-fungal silicone where joints get wet
