Questions from Chilworth Old Village

Can you help a landlord with a rental near Chandlers Ford station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Will you come out to Chilworth Old Village?

Yes. Chilworth Old Village is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

What fire rating will the seal have?

We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

What information do you need?

A short description and the location, plus pictures if you have them. If we need more, we will ask.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.

Do you hold any approvals?

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

Are you fully insured?

Yes, we are fully insured for domestic and commercial work.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Plan fire stopping into any work that goes through walls or floors
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Do not paint over fire sealant until it has cured
  • Take pictures of fire stopping before ceilings or boxing go back

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.

When to call us in Chilworth Old Village

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 is not fire-rated.

Signs it’s time to call us include:

  • Joints picked up in a fire-stopping survey
  • Gaps around pipes and cables through fire-resisting walls
  • Gaps filled with a product that isn’t fire-rated
  • Unsealed gaps around fire door frames

For buildings such as Church of St Denys, older buildings that have had new heating or wiring often have service gaps worth checking.

Questions to ask before booking

  • Are they insured?
  • What happens if the job turns out different
  • How long to leave it before use
  • Whether all the old sealant comes out first

Choosing a sealant specialist

How it works

When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints 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 Chilworth Old Village, the journey is planned in advance: let us know about lanes, gates and parking. 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. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises

Advice

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Certifying a building or signing off its fire safety
  • Openings too large for sealant, which need batts, boards or another system
  • Fire risk assessments, which need a qualified assessor

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

Surfaces we seal

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

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

What affects the cost of fire rated sealant

The quote reflects the job in front of us. We look at:

  • Whether there’s mould to deal with
  • Access and height
  • Working hours on commercial sites
  • Which sealant suits the joint

Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What to tell us for a quote

What to tell us when you ask for a quote:

  • Where the property is
  • Roughly how big the job is
  • If someone has resealed it before
  • What the problem is, such as mould, gaps, leaks or cracking

Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

Fire rated sealant around Chilworth Old Village

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Rented homes near Chandlers Ford station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as North Baddesley Junior School, gaps opened by contractors for new cabling are a common finding in schools and offices.
