Fire Rated Sealant in Lower Swanwick

Fire rated sealant near Lower Swanwick

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • File the fire-stopping record where your assessor can find it
  • Include hidden areas like risers in routine checks
  • Make resealing part of every contractor’s brief
  • Photograph sealed gaps before they’re covered up

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

About our fire rated sealant in Lower Swanwick

We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with linear gaps at the head of walls and holes left by a change of layout, we can put it right.

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

A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

What affects the quote in Lower Swanwick

You will get a clear quote before work begins. It’s based on:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • When we can work, for business premises
  • The amount of work

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

Helping us quote

To make quoting easier, please include:

  • Where the job is, and your postcode

Questions from Lower Swanwick

Is Lower Swanwick in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Lower Swanwick is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.

Can you help a landlord with a rental near Bursledon station?

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

Can you seal over the old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

How do I get a quote for fire rated sealant in Lower Swanwick?

Size, access and the old material all affect the cost. Call for a quick quote.

Can I use normal mastic around a pipe through a fire wall?

No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed and we can apply it for you.

Do you hold any approvals?

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

What’s the difference between intumescent and fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.

Can I choose the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Different surfaces, different methods

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

Flats and HMOs

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

Fire rated sealant around Lower Swanwick

For seaside hotels, guest houses and holiday lets around Lower Swanwick, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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.

Managing a site like Bursledon Church of England Infant School? Then service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of St Leonard, gaps around pipes and cables are worth checking after any building work there. Letting a property close to Bursledon station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

How it works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Lower Swanwick, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  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. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules

Why act early in Lower Swanwick

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In a small place like Lower Swanwick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
