How we handle washroom sealing in Caterham
In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. If you have a new bead over an old one coming away and discoloured joints around urinals and WC pans, we can help. Whoever orders the work in Caterham, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
For schools in a town such as Caterham, term dates decide when the toilets and changing rooms can be resealed, while offices and care homes need phased work. Let us know your opening times and any access limits, and we’ll work to them.
Every job we finish is backed by a 12-month workmanship guarantee, in Caterham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Building owners, agents and FMs in Caterham
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Keeping the joints sound
For the best life from the joints:
- Leave signs up until the cure time is over
- Add sealant joints to planned maintenance checks
- Don’t leave trays and floors sitting wet
- Act on the first split you see at a shower tray
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Your questions answered
Can you work in a care home near Caterham with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is hospital work, at somewhere like North Downs Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you reseal washrooms in healthcare buildings?
Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Is there a guarantee on the work?
There is a 12-month guarantee on our workmanship backed by public liability insurance.
Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Vanity carcasses that have swollen
- Failed tanking beneath a wet-room floor or behind tiles
- Condensation from failed extract fans
If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Caterham lies roughly 15 miles out from central London, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open. Three care or nursing homes sit less than 2 miles from Caterham. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Work is agreed with the manager, around residents’ routines.
For a site such as North Downs Hospital, 1 mile to the south-east of Caterham, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For a hall at a building such as Sacred Heart Church, resealing the kitchen and toilets can be fitted between bookings. Customer toilets and staff facilities at retail sites such as Church Walk Shopping Centre (0.7 miles south-east of Caterham) need sealant that stays clean under heavy use.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
