Questions from Sandon
Is Sandon within the area you cover?
Yes, Sandon is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Ashwell & Morden station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used for your files.
How we handle fire rated sealant in Sandon
We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. We are often asked to deal with standard silicone or caulk in a fire-stopping gap and old fire sealant that has split or come away, on door frames, flats & HMOs and plasterboard & masonry.
Work in a small place like Sandon is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Landlord and commercial work in Sandon
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Problems with the door itself rather than the gap around the frame
- Construction that does not provide fire resistance on its own
- Issuing a fire rating or certificate for a building
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Pipe & cable gaps
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
- Linear gaps
- Door frames
Common problems we fix in Sandon
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Common reasons people contact us include:
- Joints picked up in a fire-stopping survey
- Open holes round services passing through fire walls
- Gaps filled with a product that is not fire-rated
- New service routes left unsealed after building work
For site and facilities teams at buildings such as Sandon Junior Mixed and Infant School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- Who does the work, and how experienced they are
- Whether they’re fully insured
- When the joint can take water or movement
- Is the old sealant removed completely?
Other services in Sandon
Commercial buildings in Sandon
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Rented homes near Ashwell & Morden station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Sandon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.

Related advice
Why act early in Sandon
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Older cottages and farmhouses around Sandon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Make resealing part of every contractor’s brief
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
- Check risers, ceiling voids and cupboards during building checks
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
