How we handle fire rated sealant in Hatfield
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on plasterboard & masonry, pipe & cable gaps and service penetrations, and people most often call us about joints picked up in a fire-stopping survey and cracked or shrunken fire-rated sealant.
Shared washrooms take far more use than a home bathroom, and their sealant shows it, while fire-rated sealant has to be made good whenever new pipes or cables go through. In Hatfield, timings are planned around the building.
All of our work is guaranteed for twelve months, in Hatfield and everywhere else we cover.

What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In Hatfield, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What the job involves on each surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Landlords, agents and businesses in Hatfield
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Workplaces and buildings in Hatfield
Hatfield was built as one of England’s post-war new towns. Hatfield was planned with its own industrial and business areas, so workplaces sit close to the homes. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. There are hotels and other places to stay in and around Hatfield. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a church, hall or community building such as Church of St Luke, gaps around pipes and cables are worth checking after any building work there. Managing a site like Bishop's Hatfield Girls' School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it with a record of each location.
Can I use normal mastic around a pipe through a fire wall?
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 tell me which gaps need fire stopping?
No, assessment is not something we do. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

Do you need fire rated sealant in Hatfield?
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Any of these means the joints need attention:
- Fire seals that have cracked with movement
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps where pipes and cables go through a wall
Letting a property close to Hatfield station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before booking
- Is VAT in the price?
- Is the old sealant removed completely?
- Who does the work, and how experienced they are
- Whether you can choose the colour
