When to call us in Forestdale
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.
Look out for the following:
- Sealant lifting along a tray edge
- Sealant stained black around basins and showers
- Stained sealant around pans and urinals
- Washrooms that look worn because of the sealant
On a healthcare site such as Bethlem Royal Hospital, which lies north of Forestdale, washroom work starts with the infection-control team’s sign-off.

Washroom sealing in Forestdale
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. An open joint there lets water track under flooring or behind wall panels so they get particular attention. If you are dealing with a new bead over an old one coming away and mould spotting along silicone joints, we can help, on urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors alike. One point of contact handles commercial sealant work in Forestdale from the first photographs to the final walk-round, whether it’s one building or several.
In Forestdale, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief cleaning staff to treat joints gently
- Keep a record of which washrooms need attention
- Leave signs up until the cure time is over
- Mention any site permits or estates rules at quote stage
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Forestdale can sit alongside others in a wider programme.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. 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.

With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

Give us the hours we can be on site and we will schedule to suit.

- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.

Forestdale: questions and answers
Would you work within a site like Bethlem Royal Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as John Ruskin College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
What will the job cost?
We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Wet areas in Forestdale’s workplaces
In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team. The area within 2 miles of Forestdale holds several hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.
Toilets at colleges like John Ruskin College (0.5 miles north-west of Forestdale) take heavy use from students and staff alike. En suites at hotels like Selsdon Park Hotel, 1.1 miles west of Forestdale, are cleaned daily, which wears silicone over time.

Around Forestdale

Nearby you’ll also find Warlingham Park Hospital (1.9 miles south) and Croydon Airport Visitor Centre (3.5 miles west). Green spaces nearby include Nore Hill and Hutchinson's Bank.
Leave it or put it right?
Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
