Your questions about fire rated sealant in South Ham

Do you work for landlords with property near Basingstoke station?

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

Do you cover smaller places like South Ham?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Do you take on fire stopping in schools and offices?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in.

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

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service.

Fire rated sealant in South Ham, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, service penetrations and flats & HMOs, and common reasons people get in touch are new service routes left unsealed after building work and open holes round services passing through fire walls.

In a smaller place like South Ham, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Store the list of sealed gaps with your building paperwork
  • Plan fire stopping into any work that goes through walls or floors
  • Ask every contractor to reseal any fire stopping they disturb
  • Do not fill fire-stopping gaps with ordinary foam or silicone

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

What the job involves on each surface

Masonry and concrete

Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.

What we cannot put right

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

  • Problems with the door itself rather than the gap around the frame
  • Openings too large for sealant, which need batts, boards or another system
  • Construction that does not provide fire resistance on its own

If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

What we seal

  • Pipe & cable gaps
  • Service penetrations
  • Door frames
  • Flats & HMOs
  • Plasterboard & masonry
  • Linear gaps

When to call us in South Ham

Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

Signs it’s time to call us include:

  • Gaps where walls meet ceilings or slabs
  • Holes left by a change of layout
  • Sealant items on a fire risk assessment action list
  • Open holes round services passing through fire walls

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

What affects the cost of fire rated sealant

There’s no set price list. The quote depends on:

  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved
  • Working hours on commercial sites

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Pictures of the joints, sent by email
  • Roughly how big the job is
  • Any access issues, like height or stairs
  • Any previous sealing or DIY work

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.

Fire rated sealant in South Ham: local notes

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’re given, installing the product to its tested details.

Community buildings like Saint Peter's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Managing a site like St Anne's Catholic Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
