Quotes for fire rated sealant in Watford
We quote each job individually. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The type of sealant required
- How much there is to do
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote
To help us quote quickly, please include:
- The address or postcode of the job
- The type of property
- Any previous sealing or DIY work
- Photos by email, if that’s easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
What we cannot put right
We won’t take on work that will not last, so these are the limits:
- Problems with the door itself rather than the gap around the frame
- Walls or floors that weren’t built to resist fire
- Certifying a building or signing off its fire safety
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
What we seal
- Flats & HMOs
- Service penetrations
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
What we’re called out for in Watford
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Keep an eye out for these signs:
- Holes left by a change of layout
- Seals cut through by electricians, plumbers or data installers
- Linear gaps at the head of walls
- Gaps around pipes and cables through fire-resisting walls
For buildings such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.
What to look for in a quote
- Which sealant they’ll use, and why
- Whether you can choose the colour
- Is VAT in the price?
- How the joint is cleaned and prepared
Why it’s worth doing now in Watford
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Busy buildings in Watford, from hotels to offices, can’t afford rooms out of use for leaks or mould, so failing joints are best replaced on a planned basis.
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.
What you get with us
- Over 20 years’ experience
- Approved under the ARBOMaster scheme
- Old sealant always removed completely
- Anti-fungal silicone where joints get wet
Questions from Watford
I let a flat near Watford Junction station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you take on hotel work around Watford?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will you assess my building’s fire safety?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Can ordinary silicone be used in a fire-stopping gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. For homes and businesses in busier parts of Watford, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

Different surfaces, different methods
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach and we’ll flag it.
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep the record of products and locations with your fire safety documents
- Make resealing part of every contractor’s brief
- Keep photos of seals that will be hidden
- Flag any open gap you spot round a pipe or cable
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
Workplaces and buildings in Watford
Watford has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. 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, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Watford St John's Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Watford Junction station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
