How we handle fire rated sealant in Headington Hill
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and the jobs we see most are joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall.
In a smaller place like Headington Hill, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
A 12-month guarantee comes as standard.

When to call us in Headington Hill
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
People normally contact us after spotting one of these:
- New service routes left unsealed after building work
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
- Seals cut through by electricians, plumbers or data installers
For buildings such as All Saints' Church, older buildings that have had new heating or wiring often have service gaps worth checking.
Before you book anyone
- Who does the work, and how experienced they are
- Which colour the sealant will be
- Whether the sealant suits the joint
- What guarantee comes with the work
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Sign-off of the building, which sits with building control or your assessor
- Fire risk assessments, which need a qualified assessor
- Construction that doesn’t provide fire resistance on its own
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Door frames

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
- Never patch a fire seal with standard sealant
- Get damaged fire seals looked at promptly
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Workplaces and buildings in Headington Hill
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. There are hotels and other places to stay in and around Headington Hill. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Schools such as Cheney School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Oxford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What affects the cost of fire rated sealant
We do not publish a price list, because jobs vary so much. What we look at:
- Access and height
- The number and length of the joints
- When we can work, for business premises
- Mould in or behind the old joints
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before we start.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Pictures of the joints, sent by email
- Roughly how big the job is
- The type of property
- If someone has resealed it before
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
How the visit works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours for a handful of gaps, and longer for a whole building, and we explain the cure time before we leave. A visit to Headington Hill is planned like any other: the time, the access and where to park are agreed in advance. 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.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- Mention any parking rules near the property
- Clear the area around the work
- Mention any sign-in or site rules at work premises

How the job changes by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
