  • Failed joints in office kitchens and tea points
  • Too many rooms to reseal without closing the building

Commercial sealant for Washington homes and businesses

Surface by surface

Hotel bathrooms

Guest bathrooms are resealed room by room or in batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.

Retail & leisure sites

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

About our commercial sealant in Washington

Hotel bathrooms take hard daily use and constant cleaning, so sealant wears out faster than it would at home. We work through rooms in batches, so only a few are out of use at once. We work on rental portfolios, student & care accommodation and retail & leisure sites, and common reasons people get in touch are rental bathrooms that need resealing between tenants and silicone laid over old silicone by a previous contractor.

For holiday lets, converted business premises or a community building near Washington, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

There’s a 12-month guarantee on every job, large or small.

Commercial buildings in Washington

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

For buildings such as The Parish Church of St Mary, any kitchen and washrooms need the same sealant care as any other building.

FAQs for Washington

Do you cover smaller places like Washington?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you cover Washington for commercial sealant?

Yes, Washington is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.

Do the sealants smell?

It depends on the product. Some smell for a while, some hardly at all.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

Can you seal over the old sealant?

No, and we never do. 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 you provide RAMS?

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

Do you offer different sealant colours?

In most cases you can choose. We’ll tell you which colours the right product comes in.

Do you guarantee commercial jobs?

Yes. Every job, domestic or commercial, carries our one-year guarantee.

What affects the cost of commercial sealant

We quote each job individually. These are the things that affect it:

  • How many areas need sealing
  • Working hours on commercial sites
  • The type of sealant required
  • Whether the work is at height

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • Where the property is
  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
  • The type of property

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or email us.

When to call us in Washington

A hotel shower or office washroom is used many times a day, and daily cleaning with strong chemicals wears sealant down. So the silicone ages faster than it would at home.

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

  • Washroom sealant that looks dirty however often it’s cleaned
  • Tired sealant in let properties
  • Joints that need doing before an inspection or audit
  • Repeated reseals that do not last

For site and facilities teams at buildings such as St Mary's CofE Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What to look for in a quote

  • Who does the work, and how experienced they are
  • The length of the guarantee
  • What product goes in the joint
  • Whether they seal over old material or remove it

10 questions to ask before you book

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours per room, so whole buildings are phased from start to finish. For a village or hamlet like Washington, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Room by room, we protect the area and remove all the old sealant.
  3. The joints are degreased, treated and left to dry.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Mention any leaks or damp you’ve noticed
  • Try not to wet indoor joints just before the visit

Ask for a quote

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

Honest limits

Sealant isn’t the answer to every problem, and we will tell you before we start. It will not solve:

  • Tiles coming off the wall
  • A broken extractor fan behind the mould problem
  • Water coming from plumbing rather than sealant

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
