Intumescent and fire-rated sealant around gaps, frames and service penetrations for Apsley, backed by a one-year guarantee. Ask us for a quote.
- Door frames with gaps between frame and wall
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Apsley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
Ask for a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
Advice
Fire rated sealant for homes and businesses in Apsley
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on, gap by gap. If you are dealing with gaps around pipes and cables through fire-resisting walls and standard silicone or caulk in a fire-stopping gap, we can put it right.
Commercial work around a smaller place like Apsley usually means a pub, a shop, a school or small business units rather than office blocks. The work is the same as in a big building, just on a smaller scale.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

How to look after the new joints
So the new joints stay in good condition:
- Make resealing part of every contractor’s brief
- Ask which product was used before you paint
- Take pictures of fire stopping before ceilings or boxing go back
- Get damaged fire seals looked at promptly
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.
How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- How many areas need sealing
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In an older home around Apsley, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start.
Why book with us
- Domestic, commercial and hotel work
- 12-month guarantee on every job
- ARBOMaster approved applicator

Workplaces and buildings in Apsley
Hemel Hempstead, which Apsley is part of, is one of England’s post-war new towns. Like the other new towns, Hemel Hempstead was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as Two Waters Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Apsley station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Fire doors that need new seals, closers or hardware
- Issuing a fire rating or certificate for a building
- Construction that doesn’t provide fire resistance on its own

Questions from Apsley

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Apsley?
Yes, we do. 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.
How long will you be here?
Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we will tell you how long to expect.
What information do you need?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
What fire rating will the seal have?
That isn’t something we state or certify. Your specification sets the requirement, and we apply a product tested for it with a record of each location.
