When to call us in Gallowstree Common

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Clients typically get in touch after noticing one or more of the following:

  • Mould spotting along silicone joints
  • Open joints along basins and vanity units
  • A new bead over an old one coming away
  • Sealant lifting along a tray edge

At a university such as University of Reading, which lies south-east of Gallowstree Common, summer is the usual window for resealing residence bathrooms.

What to look for in a quote

  • How they’ll work around occupants
  • What site paperwork they can supply
  • What level of public liability insurance do they hold?
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

What sets the cost

What shapes the price:

  • Access and working height
  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Distance, for remote addresses

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Whether an asbestos survey exists
  • The type of building and who uses it
  • The product your specification calls for
  • Drawings or a marked-up plan, if available

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email the details over with what you know.

Why deal with it now?

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Around Gallowstree Common, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why clients in Gallowstree Common choose us

  • Fully insured
  • Matching to RAL references, product permitting
  • Products installed to the manufacturer’s instructions
  • Work carried out by CSCS-carded applicators

What the job involves on each surface

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
