How the job changes by surface

Flats and HMOs

Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the seal has something sound to bond to.

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Include fire stopping when you schedule refits
  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • File the fire-stopping record where your assessor can find it

Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.

For landlords and businesses

Housing providers, facilities teams and property managers book us too in Blackbird Leys and across Oxfordshire. We can quote a run of properties together, and we are fully insured.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

When to call us in Blackbird Leys

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The problems people generally mention when they call are:

  • Joints picked up in a fire-stopping survey
  • Gaps where walls meet ceilings or slabs
  • Ordinary sealant used where a fire-rated product was needed
  • Cracked or shrunken fire-rated sealant

Letting a property close to Radley station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before booking

  • How the joint is cleaned and prepared
  • Whether the sealant suits the joint
  • How much experience the applicator has
  • How the colour is chosen

How the visit works

Before we leave, we go over the finished joints with you. The visit itself normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. A visit to Blackbird Leys 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.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height
  • Mention any parking rules near the property

Should I try it myself first?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

FAQs for Blackbird Leys

Do you take on hotel work around Blackbird Leys?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Will you come out to Blackbird Leys?

Yes. Blackbird Leys is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

What do you put in the joint?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Do you certify the fire stopping?

We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

Is it OK to seal over old sealant?

No. We remove every bit of old sealant first, so the new sealant bonds properly.

Can ordinary silicone be used in a fire-stopping gap?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

Workplaces and buildings in Blackbird Leys

There are hotels and other places to stay in and around Blackbird Leys. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.

If you look after a building such as St John Fisher Catholic Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of the Holy Family are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
