Washroom sealing near Lambs Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Common problems we fix in Lambs Green

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.

These are often picked up first by site or facilities staff:

  • Gaps where vanity tops meet the wall
  • Complaints from staff, guests or users about tired washrooms
  • Sealant laid over old silicone and now peeling
  • Open joints at the base of cubicle panels

Welfare facilities in units on estates such as Holmbush Potteries Industrial Estate (to the south-east of Lambs Green) have showers, toilets and kitchens with sealant that works hard.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • Who will actually carry out the work

How to choose a sealant contractor

About our washroom sealing in Lambs Green

From one staff toilet in Lambs Green to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Site teams most often ask us about split or peeling sealant at shower trays and sealant laid over old silicone and now peeling, across vanity units and basins, accessible toilets and changing rooms and kitchens and tea points. Looking for mastic applicators who cover Lambs Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Smaller places such as Lambs Green still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. One visit to deal with every failing joint makes more sense than several trips to a place like Lambs Green. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Standard and matched colours in many product ranges
  • Health and safety: CHAS accredited
  • CSCS-carded applicators
  • Specification-led, product-correct work

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a morning or so for a small washroom, longer where showers and changing rooms are included. Jobs in and around smaller places like Lambs Green are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open
  • Send your site hours and access windows

Advice

How the job changes by surface

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

Toilets, showers and kitchens around Lambs Green

Lambs Green is about 27 miles from central London. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

For a site such as Crawley Hospital, 2.7 miles to the east of Lambs Green, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. At a school such as Rusper Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Lambs Green is about 3 miles west of Crawley, in West Sussex.

Common questions from Lambs Green clients

Is hospital work, at somewhere like Crawley Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Is Lambs Green off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Is old silicone taken out first?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

How do I request a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Joint width, depth and condition

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • Your programme or deadline
  • The site address and postcode
  • Drawings or a marked-up plan, if available
  • The product your specification calls for

To get a fixed quote, call 01277 525 020 or send photos by email. Our quote form is another easy route.
