Washroom sealing across Roxbourne
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Maintenance after handover
For the best life from the joints:
- Respect the cure time before reopening each room
- Don’t leave trays and floors sitting wet
- Keep extract fans working and vents clear
- Tell us about infection-control or permit rules before we quote
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Advice
Commercial washrooms in Roxbourne
Several hotels sit less than 2 miles from Roxbourne. 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. A London building with hundreds of occupants can’t lose every washroom for a day, so we phase the work core by core or floor by floor with the building manager.
On a healthcare site such as Cygnet Hospital (2 miles east of Roxbourne), washroom work starts with the infection-control team’s sign-off. Student showers at universities like Westminster University, 2.6 miles east of Roxbourne, see more use than most, and their silicone shows it.

Questions about Roxbourne
Can work at a site such as Westminster University fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Would you work within a site like Cygnet Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
How long does a job like this take?
It depends on the scope, but the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you guarantee washroom sealing?
Our workmanship has a 12-month guarantee backed by public liability insurance.
When to call us in Roxbourne
Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
It’s worth sending us details if you spot any of the following:
- Split or peeling sealant at shower trays
- Discoloured joints around urinals and WC pans
- Kitchen worktop joints that can’t be kept clean
- Mould spotting along silicone joints
For a hall at a building such as St. Andrew’s Church, resealing the kitchen and toilets can be fitted between bookings.
What to look for in a quote
- Will RAMS and insurance details be available?
- Are they CHAS accredited or on Constructionline?
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
What affects the price in Roxbourne
Quotes vary with the job. It mainly depends on:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
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.
What to include in your enquiry
However big the job, the same details help:
- Your programme or deadline
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Any specification or named product
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Doing it in-house
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, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
