Fire rated sealant in Sacombe

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have fire seals that have cracked with movement and gaps filled with a product that isn’t fire-rated, we can put it right.

Somewhere as small as Sacombe, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Each job carries a 12-month guarantee, whatever its size.

What fire rated sealant looks like in Sacombe

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.

Community buildings like Church of St Katherine are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. For landlords with property near Watton-At-Stone station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Sacombe questions

Can you help a landlord with a rental near Watton-At-Stone station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Is Sacombe in your area for fire rated sealant?

Yes, Sacombe is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.

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

No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you fill the gap behind a fire door frame?

Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.

Where do you work from?

We work from Crawley. We cover Sacombe and the rest of Hertfordshire, along with the rest of our area.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you work in occupied buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.

Keeping the joints in good condition

Looking after new joints is easy:

  • Allow for resealing whenever new services are run
  • Take photos of fire stopping before ceilings or boxing go back
  • Do not paint over fire sealant until it has cured
  • Report cracked or damaged seals as soon as you notice them

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

Surface by surface

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.

Linear gaps

Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run leaving no stretch unsealed.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

What affects the quote in Sacombe

  • Any mould that needs treating
  • When we can work, for business premises
  • Which sealant suits the joint
  • The size of the job

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What we need to know

To help us quote quickly, please include:

  • The type of property
  • Any access issues, like height or stairs
  • Where the job is, and your postcode
  • What’s wrong with the joints now

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.

The process

On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Sacombe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Clear the area around the work
  • Keep pets and children clear of the area while we work
