How to choose a sealant contractor

Washroom sealing in Upper Lambourn, done properly

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. Site teams most often ask us about mould spotting along silicone joints and shower tray joints that have opened up, on kitchens and tea points, vanity units and basins and IPS panels and cubicles. For commercial sealant work in Upper Lambourn, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller places such as Upper Lambourn still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Common questions from Upper Lambourn clients

What paperwork can you provide for a job in Upper Lambourn?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is Upper Lambourn off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Do you work in hospitals, clinics and care homes?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Surface by surface

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Act on the first split you see at a shower tray
  • Include joints in routine washroom inspections
  • Respect the cure time before reopening each room
  • Share your site rules when you send details

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Upper Lambourn, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints
