Washroom sealing for commercial buildings in Sarisbury Green

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on accessible toilets and changing rooms, kitchens and tea points and IPS panels and cubicles, and the failures we are asked to look at most are kitchen worktop joints that can’t be kept clean and failed joints along IPS and cubicle panels. Facilities teams, main contractors and managing agents in Sarisbury Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around Sarisbury Green, washroom work usually comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water
  • Condensation from failed extract fans

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Joints and surfaces we work on

  • Urinals and WCs
  • Accessible toilets and changing rooms
  • Vanity units and basins
  • Showers, trays and wet room floors
  • Kitchens and tea points
  • IPS panels and cubicles

How the job changes by surface

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.

Why it’s worth doing now in Sarisbury Green

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Small buildings around Sarisbury Green suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

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.

Questions about Sarisbury Green

Is a smaller place like Sarisbury Green outside your area?

No. Places such as Sarisbury Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Will all the washrooms in our Sarisbury Green building be closed at once?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Sarisbury Green, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Have the specification and drawings to hand
  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions

Keeping Sarisbury Green washrooms open while we work

Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. Sarisbury Green is about 68 miles from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

For a hall at a building such as Church of St Paul, resealing the kitchen and toilets can be fitted between bookings.
