Washroom sealing in Dedham, done properly
Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. The enquiries we see most involve stained or open joints at kitchen sinks and worktops and failed sealant behind washroom basins, across IPS panels and cubicles, accessible toilets and changing rooms and showers, trays and wet room floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dedham, preparation and product choice get the time they need.
Halls and community buildings near places like Dedham are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
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 are clear about what is covered before work starts.

Why it’s worth doing now in Dedham
Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Halls, stores and units around places like Dedham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

A fixed quote reflects the actual work. It takes account of:
- Quantities, in metres or numbers
- Working within restricted access windows
- Joint width, depth and condition
- Location, for remote and island sites
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- The postcode of the building
For a fixed quote, speak to us on 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.
Keeping Dedham washrooms open while we work
A 2-mile radius around Dedham takes in several hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. At about 56 miles from central London, Dedham is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.
Clinical washrooms at sites like Severalls Hospital (to the south-west of Dedham) are scheduled with the ward so the room is out of use for as little time as possible. Office toilets at parks like Blue Barns Business Park, 2.4 miles south-west of Dedham, take steady weekday use, and mouldy silicone soon shows.
Dedham is about 6 miles north-east of Colchester, in Essex. Any commercial site in Dedham is covered, for single jobs and planned programmes alike. Our Essex coverage takes in 644 places. Sites around London have their own page, about 56 miles away.
Work on washrooms and wet areas is covered throughout CO7, for business premises of every kind. Buildings on High Street, School Lane and The Drift are within our area for washrooms and wet areas. Just outside Dedham, we also work in Lamb Corner (1 mile south-west), Dedham Heath (1 mile south), Stratford St Mary (1 mile north-west), Ardleigh Heath (2 miles south) and Higham (2 miles north-west). Further afield, our area takes in Colchester (6 miles south-west), Clacton-on-Sea (13 miles south-east), Harwich (12 miles east), Camulodunum (7 miles south-west), Halstead (15 miles west) and Greenstead (5 miles south-west).
Landmarks near Dedham

Nearby you will also find Severalls Hospital (4.9 miles south-west) and Little Wenham Castle (4.1 miles north-east). Green spaces nearby include Cattawade Marshes.
When to call us in Dedham
Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.
Typical triggers for a call:
- Mould spotting along silicone joints
- Sealant laid over old silicone and now peeling
- Sealant lifting along a tray edge
- Stained or open joints at kitchen sinks and worktops
For a school such as Dedham Church of England Voluntary Controlled Primary School, washroom and kitchen sealant can be renewed around term dates.

Advice
Surface by surface
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.
Common questions from Dedham clients
Do hotels near Dedham have to close for sealant work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
Is Dedham too far out for you?
No. Places such as Dedham are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
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.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
