Fire rated sealant for Stonor homes and businesses

Why it’s worth doing now in Stonor

If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. In a small place like Stonor, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Why Stonor customers choose us

  • An ARBOMaster approved applicator

Fire rated sealant for homes and businesses in Stonor

We can work through a building room by room or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on linear gaps, service penetrations and flats & HMOs, and common reasons people get in touch are old fire sealant that has split or come away and standard silicone or caulk in a fire-stopping gap.

If you have holiday lets, a converted barn used for business or a community building near Stonor, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Whatever the size of the job, it’s backed by our one-year guarantee in Stonor and across Oxfordshire.

How we quote for fire rated sealant

Every job gets its own quote. These are the things that affect it:

  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • How many rooms, windows or areas are involved
  • Any mould that needs treating

What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • Where the job is, and your postcode
  • The type of property
  • Roughly how big the job is

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.

What we can’t put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Large holes that need a different fire-stopping system
  • Construction that does not provide fire resistance on its own
  • Certifying a building or signing off its fire safety

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

What happens on the day

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. Somewhere like Stonor needs a little journey planning: 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 start with the survey or action list, checking the size and surfaces of every gap.
  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. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we are working on
  • For indoor joints, keep the area dry beforehand if you can

Related advice

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Your questions about fire rated sealant in Stonor

Do you cover smaller places like Stonor?

Yes. Stonor 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.

Yes, Stonor is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

What do you need from me for a quote?

A short description and the location. We will ask anything else we need to know.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can I add another job to the visit?

Of course. Doing several areas at once is usually more efficient.

Can you seal over the old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Commercial buildings in Stonor

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 work to the specification you are given, installing the product to its tested details.

Community buildings like Pishill Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Around Stonor, as everywhere, fire rated sealant is only as good as the preparation behind it.

Can I do it myself?

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Ask which product was used before you paint
  • Store the list of sealed gaps with your building paperwork
  • Photograph sealed gaps before they’re covered up
  • Allow for resealing whenever new services are run

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.

If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so the item can be closed.
