DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Fire rated sealant for homes and businesses in Upminster
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. Common call-outs are for cracked or shrunken fire-rated sealant and gaps left after a refit or conversion, across service penetrations, plasterboard & masonry and door frames.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Upminster cannot close.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Which sealant suits the joint
- When we can work, for business premises
- How easy the joints are to reach
- The old material and how stubborn it is
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Where the job is, and your postcode
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
What happens on the day
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. The work normally takes from a few hours to a few days, depending on the number of gaps and the access. In Upminster, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check whether a sealant can be painted before decorating over it
- Keep pictures of seals that will be hidden
- Plan fire stopping into any work that goes through walls or floors
- Tell trades working in the building that fire seals must be put back
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
Workplaces and buildings in Upminster
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
If you look after a building such as Upminster Junior School, service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Upminster station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
What the job involves on each surface
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
