Commercial sealant in Bull's Green

Surface by surface

Rental portfolios

Good sealant prevents leaks that cause bigger repairs, especially where you rarely see the bathroom yourself.

Hotel bathrooms

In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.

About our commercial sealant in Bull's Green

For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once. Typical jobs include silicone laid over old silicone by a previous contractor and black, stained silicone in guest bathrooms, on welfare facilities, rental portfolios and hotel bathrooms.

If you have holiday lets, a converted barn used for business or a community building near Bull's Green, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Every job is covered by our one-year guarantee.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the quote in Bull's Green

There’s no set price list. The quote depends on:

  • The product the joint needs
  • When we can work, for business premises
  • Any mould that needs treating
  • The number and length of the joints

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What to tell us for a quote

To help us quote quickly, let us know:

  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode
  • If someone has resealed it before
  • A few pictures by email, if you can

We don’t publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or send us an email.

When it is not the sealant

It helps to know what we can’t do:

  • Water damage behind the tiles that needs a tiler or builder
  • Poor ventilation that keeps bringing mould back
  • A shower tray, bath or basin that’s cracked or broken

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

Joints and surfaces we work on

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

Why deal with it now?

Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We will tell you if we find anything that needs another trade. In a small place like Bull's Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

  • A 12-month guarantee on all work
  • Quality sealants from Arbo and Everbuild

How it works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single washroom, longer for a whole building and we leave things clean and tidy. Somewhere like Bull's Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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 we start.
  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. Rooms are handed back in order, each with its cure time.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
