Commercial sealant for homes and businesses in Digswell
Commercial work is planned around the building, not the other way round. Rooms can be done one at a time, floor by floor or in batches, and out-of-hours work or early starts can be arranged where it helps. We work on hotel bathrooms, student & care accommodation and retail & leisure sites, and people most often call us about too many rooms to reseal without closing the building and joints that need doing before an inspection or audit.
For a pub, café, guest house or shop in or near Digswell, its washrooms and kitchen need the same sealant care as any big building.
All of our work is guaranteed for twelve months, in Digswell and everywhere else we cover.

What we are called out for in Digswell
Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. That’s when black mould sets into the bead.
Common reasons people contact us are:
- Mouldy bathrooms flagged at a tenancy check
- Silicone laid over old silicone by a previous contractor
- Failed floor-level joints in accessible wet rooms
- Split sealant around staff kitchen worktops and sinks
For site and facilities teams at buildings such as Harwood Hill Junior Mixed Infant and Nursery School, busy washrooms and kitchens can be resealed in phases so they stay open.

- Which sealant they’ll use, and why

Questions from Digswell
Do you cover smaller places like Digswell?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Welwyn North station?
Yes, we work for landlords and letting agents. 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.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Can you work outside opening hours?
In many cases. Tell us your opening hours and quiet times, and we will see what can be arranged.
Do you take on large, multi-room jobs?
Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant work cannot fix
To be straight with you, there are a few things sealant won’t fix:
- Damaged sanitaryware that needs replacing
- Assessing what fire stopping a building needs
- Extraction that is not working, which needs an electrician or ventilation contractor
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes as long as the scope needs, from one welfare room to a full building. A visit to Digswell is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

How to look after the new joints
Aftercare is simple:
- Act on lifting sealant before it leaks
- Log resealing so you know what’s due
- Add sealant to your planned maintenance checks
- Tell cleaning staff when each room can be used
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.
How we quote for commercial sealant
You will get a clear quote before any work starts. It’s based on:
- How many areas need sealing
- Whether the work is at height
- When we can work, for business premises
- How much there is to do
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- If someone has resealed it before
- Where the property is
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.

What the job involves on each surface

Student & care accommodation
Many accommodation blocks have rows of similar en suites. We agree a programme and work through them steadily.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
