How we quote for commercial sealant

The price is agreed before any work begins. It takes into account:

  • How easy the joints are to reach
  • Any mould that needs treating
  • Whether old sealant or filler has to be cut out
  • The number and length of the joints

Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

To help us quote quickly, let us know:

  • The address or postcode of the job
  • Any previous sealing or DIY work
  • If it’s domestic, commercial or a hotel
  • Pictures of the joints, sent by email

There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.

About our commercial sealant in Slough

Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. Rooms are resealed in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. Common call-outs are for washroom sealant that looks dirty however often it’s cleaned and whole floors of tired en suites, on hotel bathrooms, retail & leisure sites and student & care accommodation.

Landlords with flats and shared houses in Slough often need both kinds of work: resealing bathrooms and kitchens, and fire-rated sealant where pipes pass through walls. We can quote for a single property or a whole portfolio.

There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional finish

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Commercial buildings in Slough

There are hotels and other places to stay in and around Slough. Hotel work can be planned room by room, with out-of-hours working where needed. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a church, hall or community building such as St Michael and All Angels, halls and community kitchens see heavy use, and their sealant shows it. For site and facilities teams at buildings such as Herschel Grammar School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Common problems we fix in Slough

Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.

Signs it’s time to call us include:

  • Failed joints in office kitchens and tea points
  • Mouldy bathrooms flagged at a tenancy check
  • Tired sealant ahead of a health and safety audit
  • Sealant failing again soon after quick repairs

The process

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on the number of rooms. In Slough, we work in everything from flats and family homes to offices and hotels. For each, it helps to know about access, parking and where the joints are.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  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.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions
