About our fire rated sealant in Sutton Courtenay

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on service penetrations, flats & HMOs and plasterboard & masonry, and the jobs we see most are gaps flagged on a fire risk assessment and seals cut through by electricians, plumbers or data installers.

For a pub, café, guest house or shop in or near Sutton Courtenay, its washrooms and kitchen need the same sealant care as any big building.

You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Sutton Courtenay

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. In a smaller place like Sutton Courtenay, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

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.

Common problems we fix in Sutton Courtenay

Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave does not always get resealed.

Any of these means the joints need attention:

  • Sealant items on a fire risk assessment action list
  • Old fire sealant that has split or come away
  • Door frames with gaps between frame and wall
  • Linear gaps at the head of walls

Letting a property close to Appleford station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

FAQs for Sutton Courtenay

Is Sutton Courtenay within the area you cover?

Yes, Sutton Courtenay is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is Sutton Courtenay in your area for fire rated sealant?

Yes. We work across London and the South East, and Sutton Courtenay is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.

Do you carry out fire risk assessments?

No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.

What does intumescent mean?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Can you tell me how many minutes the seal will last?

We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How the visit works

When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a smaller place like Sutton Courtenay, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Clear items away from the joints we are working on

Workplaces and buildings in Sutton Courtenay

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like All Saints' Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Sutton Courtenay Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
