Questions about Coombe
Do hotels near Coombe have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is hospital work, at somewhere like Shirley Oaks Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
Is old silicone taken out first?
We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Washroom sealing in Coombe
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you have sealant lifting along a tray edge and a new bead over an old one coming away, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Coombe is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Coombe, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Surface by surface
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. We reseal the floor-to-wall junctions and around drains where sealant is used.
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.
Toilets, showers and kitchens around Coombe
In London buildings, toilets and showers generally need to stay partly open, which is why the work is split into phases agreed in advance. The area within 2 miles of Coombe holds plenty of 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.
If you manage an office at a site such as Twin Bridges Business Park, 1.2 miles south-west of Coombe, the washrooms and tea points can be done a floor at a time. Customer toilets in retail centres such as Whitgift Centre, 1.6 miles to the north-west of Coombe, rarely close, so resealing is phased. At a hotel such as Croydon Park Hotel, 1.1 miles north-west of Coombe, the quieter weeks are the time to reseal bathrooms.
Coombe is about 1 mile east of Croydon, in Greater London. If you’re looking for washroom sealing in Coombe, we can help, as we do across Greater London. Our Greater London coverage takes in 764 places. Sites around London have their own page, about 9 miles away.
Anyone looking for washroom sealing in CR0, CR2 and CR9 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Oaks Road, Coombe Road and Coombe Lane are within our area for washrooms and wet areas. We also cover Croydon (1 mile west), Addiscombe (1 mile north), South Croydon (1 mile south-west), Shirley Oaks (1 mile north-east) and Shirley (1 mile north-east). Bigger towns within reach include London (9 miles north), City of Westminster (11 miles north), Marylebone (11 miles north), Kensington (11 miles north-west), St Pancras (11 miles north) and Shoreditch (11 miles north).
Landmarks near Coombe
We work on buildings around Coombe Lodge pub, Royal Russell School and St Peter's Primary School and the streets around them. The closest station to Coombe is South Croydon station, about 1 mile west of the centre. Well-known places in the area include St George's Walk (1.4 miles north-west) and Croydon Airport Visitor Centre (2.1 miles west). Not far away are Bramley Bank and Duppas Hill.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. In Coombe, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We agree which washrooms close and when.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Before we start on site
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached
- Warn occupants and staff about the work
Getting a fixed quote
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in Coombe
Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Failed sealant in a building in Coombe can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

- 12 months’ guarantee on every job

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Failed tanking beneath a wet-room floor or behind tiles
- Water from plumbing, not from a joint
- Loose panels, vanity units or tiles, which need fixing first
If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Vanity units and basins
- Kitchens and tea points
- IPS panels and cubicles
- Urinals and WCs
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Note failing joints building by building
- Leave signs up until the cure time is over
- Act on the first split you see at a shower tray
- Make sure washroom ventilation is running
Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
