Rowley Green: your questions answered
Is parking an issue for commercial sealant in Rowley Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Elstree & Borehamwood station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
How long does the job take?
That depends on the amount of work, but as a guide it takes as long as the scope needs, from one welfare room to a full building. We’ll tell you when we quote.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Can you reseal every bathroom in a hotel?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.
About our commercial sealant in Rowley Green
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. If you’re dealing with shower leaks reaching the floor below and silicone laid over old silicone by a previous contractor, we can put it right, whatever the surface.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Rowley Green, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
All our work comes with our one-year guarantee.

Common problems we fix in Rowley Green
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. If a tray flexes, the sealant around it splits.
Signs it’s time to call us include:
- Water marks on ceilings under bathrooms
- Split sealant around staff kitchen worktops and sinks
- Split sealant where wet room floors meet walls
- Mouldy bathrooms flagged at a tenancy check
As a London address, Rowley Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What to look for in a quote
- What insurance they hold
- Is VAT in the price?
- Whether they seal over old material or remove it
- Who turns up on the day
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we can’t put right
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Failed tanking or loose tiles behind the sealant
- Fire risk assessments or certification
- Leaking pipework, valves or wastes (a plumber’s job)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Office washrooms & kitchens
- Retail & leisure sites
- Hotel bathrooms
- Rental portfolios
- Student & care accommodation
- Welfare facilities

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes as long as the scope needs, from one welfare room to a full building.

- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Clear the area around the work

What commercial sealant looks like in Rowley Green
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
For site and facilities teams at buildings such as Saffron Green Primary School, busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Holy Cross are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

What the job involves on each surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
Rental portfolios
Good sealant prevents leaks that cause bigger repairs.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep a record of which rooms were resealed and when
- Put a squeegee in each shower
- Check extract fans are actually running
- Schedule work around occupancy
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, with less disruption and one clear quote. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Rowley Green, the repair is bigger than a sealant job.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
