About our washroom sealing in Lyneham
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. If you’re dealing with users noticing mouldy joints and sealant laid over old silicone and now peeling, we can put it right, on IPS panels and cubicles, kitchens and tea points and vanity units and basins alike. A specialist sealant contractor works differently from a general builder: on jobs in Lyneham, preparation and product choice get the time they need.
In and around smaller places like Lyneham, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How the job changes by surface
Wet-room floors and floor-to-wall joints
Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we’ll say if the trouble looks to be beneath the floor.
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.
Washroom sealing in Lyneham: the local picture
A 2-mile radius around Lyneham takes in several hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available. Lyneham lies roughly 70 miles out from central London. Office washrooms on business parks see heavy weekday use, which is why the work is phased.
If you manage an office at a site such as Wychwood Business Centre (1.6 miles south of Lyneham), the washrooms and tea points can be done a floor at a time.
Lyneham is about 8 miles north of Carterton, in Oxfordshire. Lyneham sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 423 places across Oxfordshire fall within our area, Lyneham among them. Oxford is covered too, around 18 miles from Lyneham.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Make sure washroom ventilation is running
- Include joints in routine washroom inspections
- Don’t leave trays and floors sitting wet
- Note failing joints building by building
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 users notice. Dealing with it while it’s just the sealant keeps it simple.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Lyneham may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We survey each room, count the joints and note anything behind them that needs another trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Point out parking and an unloading spot
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
Ask for a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:

- Condensation from failed extract fans
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Your questions answered
Is Lyneham too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Must every washroom in our Lyneham building shut while you work?
Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.
Is it possible to just clean mouldy silicone?
Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What guarantee comes with washroom resealing?
Our workmanship has a 12-month guarantee, and we carry public liability insurance.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Signs you need washroom sealing in Lyneham
Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.
Site and facilities staff are often the first to spot these:
- Users noticing mouldy joints
- Stained or open joints at kitchen sinks and worktops
- Sealant stained black around basins and showers
- Discoloured joints around urinals and WC pans
Washrooms near Lyneham get the old silicone stripped out and a fresh anti-mould bead on dry joints.
