Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them.

Questions about Devil's Den

Is Devil's Den too small for you to travel to?

Not at all. Devil's Den is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do we have to close all our washrooms in Devil's Den for resealing?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How long before the toilets can reopen?

The silicone needs time to cure before water reaches it. We plan the phasing around that so facilities are never short.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Quoting for work in Devil's Den

The price varies from site to site. Expect it to depend on:

  • Any access equipment needed
  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Whether the work must be split into stages

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Access details, including height
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Commercial clients in Devil's Den

We work for building owners and managing agents on everything from one building to a spread of sites around Devil's Den. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Devil's Den. Send photos of each area and we will quote for the lot.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why us?

  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product
  • Constructionline member for supplier checks
  • Fully insured

Washroom sealing around Devil's Den: how the place shapes the job

Central London is about 36 miles from Devil's Den, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.

In any commercial washroom in or near Devil's Den, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints. On an industrial estate such as Barradale Farm Industrial Estate, 1.9 miles to the south-east of Devil's Den, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Devil's Den is about 5 miles south of Maidstone, in Kent. Anywhere in ME17, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Devil's Den is one of 931 places in Kent on our list for washrooms and wet areas. For work in that direction, see our London page.

Aftercare for building managers

For the best life from the joints:

  • Clear standing water from shower floors where possible
  • Mention any site permits or estates rules at quote stage
  • Report split joints at trays and basins early
  • Respect the cure time before reopening each room

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Devil's Den need work, visits can be combined. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Getting the site ready

  • Confirm the product named in the specification
  • Tell staff and tenants when we’ll be in
  • Tell us your opening times and when work is allowed
