Fire rated sealant near Westborough

Fire rated sealant in Westborough

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on plasterboard & masonry, linear gaps and service penetrations, and the jobs we see most are gaps filled with a product that isn’t fire-rated and gaps flagged on a fire risk assessment.

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

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition

Aftercare is simple:

  • Take photos of fire stopping before ceilings or boxing go back
  • Flag any open gap you spot round a pipe or cable
  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • A wall that isn’t a fire-resisting element to begin with
  • Fire risk assessments, which need a qualified assessor
  • Fire doors that need new seals, closers or hardware

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

Workplaces and buildings in Westborough

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. Westborough has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

Schools such as St Joseph's Catholic Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For buildings such as St Francis Church, gaps around pipes and cables are worth checking after any building work there.

Questions from Westborough

Do you work in hotels near Westborough?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Do you work for landlords with property near Guildford station?

Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

Do you come to Westborough?

Yes. We cover Westborough. For a quote, ring 0345 464 0079 or drop us an email.

Are you fully insured?

Yes. We’re fully insured.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Is standard sealant good enough for a fire gap?

No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Surface by surface

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.

Flats and HMOs

Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product.

The process

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a job in Westborough, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Mention any tricky access
  • Clear items away from the joints we are working on

For landlords and businesses

We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.

Common problems we fix in Westborough

If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.

Keep an eye out for any of the following:

  • Standard silicone or caulk in a fire-stopping gap
  • Door frames with gaps between frame and wall
  • Linear gaps at the head of walls
  • Fire stopping disturbed by later work

Rented homes near Guildford station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before you book

  • How long the guarantee is
  • How the surfaces are prepared before sealing
  • What the cure time is
  • Whether all the old sealant comes out first

10 questions to ask before booking

DIY sealant or a professional job?

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

If you’re 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 fails, we can still redo it.
