Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for washrooms and wet areas
The price varies from site to site. Expect it to depend on:
- Location, for remote and island sites
- The size and state of each joint
- Phasing around occupants
- The total length or number of joints
A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Whether the building will be occupied during the work
- The site address and postcode
- When you need the work done
- Approximate linear metres or a joint schedule
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email us.
About our washroom sealing in Kevington
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you are dealing with shower tray joints that have opened up and a new bead over an old one coming away, we can put it right, whatever the surface. A single leaking joint is often how a building in Kevington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building managers in Kevington normally need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. For a job in Kevington, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Getting the site ready
- Explain the parking and delivery arrangements
- Point out any areas we must not close
- Flag any permit to work we’ll need
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Leaks through tanking or membranes below the finishes
- Fittings that move too much to hold a bead
- Swollen or delaminated boards behind panels or vanity tops
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
- Kitchens and tea points
- Vanity units and basins
- Urinals and WCs
- IPS panels and cubicles
Leave it or put it right?
Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Washroom sealing around Kevington: points for this area
A 2-mile radius around Kevington takes in a number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. There are two care or nursing homes within about 2 miles of Kevington. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible.
For a hall at a building such as Unity Church, resealing the kitchen and toilets can be fitted between bookings. At a retail site such as Nugent Retail Park, which lies north-west of Kevington, public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases.

Questions we’re asked in Kevington
Can you take on a job at a hospital such as Chelsfield Park Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a hotel in Kevington need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Which silicone is right for commercial washrooms?
Each area gets the grade that suits it. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Looking after the joints
After handover, these steps help:
- Don’t leave trays and floors sitting wet
- Don’t leave an open joint at a basin or tray
- Brief cleaning staff to treat joints gently
- Mention any site permits or estates rules at quote stage
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
