When something else is needed

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Cracked trays or baths rather than failed joints
  • Certifying fire stopping or building compliance
  • Failed tanking or loose tiles behind the sealant

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

What we seal

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

Why act early in Winnersh

Sealant work is quick by the room: the job takes as long as the scope needs, from one welfare room to a full building. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. Homes in smaller places like Winnersh can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

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.

Why book with us

  • Colour picked to suit the job
  • 4.9 on Google from 180+ five-star reviews
  • We never seal over old sealant
  • ARBOMaster approved applicator

Signs you need commercial sealant in Winnersh

In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. Any split there can let water through quickly.

Signs it’s time to call us include:

  • Mouldy washroom sealant that staff and guests notice
  • Shower leaks reaching the floor below
  • Failed joints in office kitchens and tea points
  • Large numbers of bathrooms needing the same work

Community buildings like St Mary the Virgin are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

10 questions to ask before booking

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What happens on the day

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a few hours for a single washroom, longer for a whole building. Parking around Winnersh is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. The first visit is a look round the site to agree the scope.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

Getting ready for the visit

  • Tell us if parking is tricky
  • Let us know about earlier repairs to the joints
  • Tell us about access, such as stairs, a lift or high-level joints

Questions from Winnersh

Can you do commercial sealant in Winnersh?

How long will you be here?

Yes. Tell us about everything you’d like done and you will get one quote.

Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What sealant do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
