How we handle commercial sealant in Strawberry Hill

With over 20 years in sealant work, we are a fully insured, ARBOMaster approved team. If your site needs RAMS or insurance details, tell us, and we’ll confirm what we can supply with the quote. If you are dealing with silicone laid over old silicone by a previous contractor and water marks on ceilings under bathrooms, we can help, whatever the surface.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Strawberry Hill needs to stay open, work can be planned outside normal hours.

Every job comes with a one-year guarantee, wherever you are in Greater London.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per area, with larger sites planned over several visits. In a London area like Strawberry Hill, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. Tell us the rooms, hours and site rules, and we’ll plan the programme.
  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. Each finished area is checked with you and given a cure time.

Before we arrive

  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep pets and children clear of the area while we work

Ask for a quote

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

What affects the cost of commercial sealant

The quote reflects the job in front of us. We take into account:

  • Whether there’s mould to deal with
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What to tell us for a quote

To make quoting easier, let us know:

  • What’s wrong with the joints now
  • A few pictures by email, if you can
  • How we’d reach the joints
  • Whether it has been sealed before

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Do you need commercial sealant in Strawberry Hill?

Wet rooms and accessible showers are designed for the whole floor to get wet, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.

Signs it’s time to call us include:

  • Whole floors of tired en suites
  • Sealant failing again soon after quick repairs
  • Rental bathrooms that need resealing between tenants
  • Water marks on ceilings under bathrooms

If you look after a church, hall or community building such as Holy Trinity Church, halls and community kitchens see heavy use, and their sealant shows it.

What to look for in a quote

  • How hidden problems are handled
  • Whether all the old sealant comes out first
  • What product goes in the joint
  • Are they insured?

FAQs for Strawberry Hill

Is parking a problem for a job in Strawberry Hill?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.

Do you work for landlords with property near Strawberry Hill station?

Yes. We work for landlords and agents as well as householders, 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 will tell you what we’re using and why.

Should I try DIY first?

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

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

Do you provide RAMS?

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

When it is not the sealant

We’ll always be straight with you, so here’s what new sealant will not do:

  • Assessing what fire stopping a building needs
  • Water coming from plumbing rather than sealant
  • A broken extractor fan behind the mould problem

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

Joints and surfaces we work on

  • Hotel bathrooms
  • Retail & leisure sites
  • Welfare facilities
  • Rental portfolios
  • Student & care accommodation
  • Office washrooms & kitchens

Looking after it afterwards

Aftercare is simple:

  • Don’t leave a failed joint until the next refurbishment
  • Report broken fans quickly
  • Schedule work around occupancy
  • Add sealant to your planned maintenance checks

Include sealant in routine room inspections. A quick look at each bathroom when rooms are checked spots problems early.

Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.

Commercial sealant in Strawberry Hill: local notes

Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. Strawberry Hill has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Strawberry Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Managing a site like Kneller Hall Senior School? Then washroom and kitchen sealant can be programmed around term times or opening hours.
