Questions about Broadfields Estate
Can you work on a hospital site such as Edgware Community Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Could you schedule work at a campus like Middlesex University for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How soon can a washroom be used after resealing?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
Do you do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote before we start.
Washroom sealing for commercial buildings in Broadfields Estate
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Site teams most often ask us about stained sealant around pans and urinals and shower tray joints that have opened up, on showers, trays and wet room floors, vanity units and basins and kitchens and tea points. Facilities teams, main contractors and managing agents in Broadfields Estate tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Building managers in Broadfields Estate 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 is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- A room that stays damp because ventilation isn’t working
- A dripping waste or valve behind a panel
- Hollow tiles or loose panels behind the joint
If you’re not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.
Surfaces we seal
- IPS panels and cubicles
- Showers, trays and wet room floors
- Vanity units and basins
- Accessible toilets and changing rooms
- Kitchens and tea points
- Urinals and WCs
From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Broadfields Estate can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Point out any areas we must not close
- Let building users know which areas are affected
- Move anything stored against the joints

Surface by surface
Basins and vanity tops
Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
Toilets, showers and kitchens around Broadfields Estate
The 2 miles around Broadfields Estate include three care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Each room is kept out of use only as long as the sealant needs. A 2-mile radius around Broadfields Estate takes in a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.
At a hospital like Edgware Community Hospital, which lies south of Broadfields Estate, patient and staff washrooms are best done in short phases agreed with the ward. In a centre such as Broadwalk Centre, 1 mile south of Broadfields Estate, public washrooms are resealed a block of facilities at a time.

Why act early in Broadfields Estate
Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. Getting scaffold, permits or access booked in Broadfields Estate takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
