Fire rated sealant for homes and businesses in Digswell
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on pipe & cable gaps, service penetrations and flats & HMOs, and people most often call us about cracked or shrunken fire-rated sealant and open holes round services passing through fire walls.
Around a place like Digswell, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
There’s a 12-month guarantee on every job, whatever its size.

Workplaces and buildings in Digswell
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. Digswell has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Schools such as Harwood Hill Junior Mixed Infant and Nursery School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. If you let a flat or house near Welwyn North station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Digswell Village Church, older buildings that have had new heating or wiring often have service gaps worth checking.

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- A wall that isn’t a fire-resisting element to begin with
- Large holes that need a different fire-stopping system
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Service penetrations
- Door frames
- Flats & HMOs
- Plasterboard & masonry
- Pipe & cable gaps
- Linear gaps
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
- Take pictures of fire stopping before ceilings or boxing go back
- Check whether a sealant can be painted before decorating over it
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
How it works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes from a few hours to a few days, depending on the number of gaps and the access. A visit to Digswell is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

FAQs for Digswell
Will you come out to Digswell?
Yes. Digswell is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Welwyn North station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Will we have a record of what was sealed?
Yes. You get a list of where we worked and what we used.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Landlord and commercial work in Digswell
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What affects the quote in Digswell
Your quote is based on your job. We take into account:
- The amount of work
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Photos by email, if that’s easy
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or send us an email.
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
How the job changes by surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Flats and HMOs
Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product.
