How the visit works

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Parking around Alresford is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Any non-fire-rated filler is removed and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

Fire rated sealant for homes and businesses in Alresford

We do not 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 service penetrations, flats & HMOs and pipe & cable gaps, and the jobs we see most are door frames with gaps between frame and wall and new service routes left unsealed after building work.

Around a place like Alresford, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.

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

Common problems we fix in Alresford

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 may look fine, but it isn’t a fire-rated seal.

Any of these means the joints need attention:

  • Gaps where walls meet ceilings or slabs
  • Cracked or shrunken fire-rated sealant
  • Open holes round services passing through fire walls
  • Seals cut through by electricians, plumbers or data installers

For landlords with property near Alresford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

How to choose a mastic man

Surface by surface

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.

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.

Landlords, agents and businesses in Alresford

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Why deal with it now?

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. In an older home around Alresford, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Take pictures of fire stopping before ceilings or boxing go back
  • Keep the record of products and locations with your fire safety documents
  • Ask which product was used before you paint

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

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

Common questions in Alresford

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

Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.

Is Alresford in your area for fire rated sealant?

What does fire rated sealant cost?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or email us and tell us what needs doing and where.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

Will we have a record of what was sealed?

Yes. We record the locations we’ve sealed and the products used for your files.

What fire rating will the seal have?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.

Can you do several jobs on one visit?

Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Honest limits

Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:

  • Sign-off of the building, which sits with building control or your assessor
  • Doors that aren’t fire doors in the first place
  • Big openings where sealant alone isn’t the tested solution

Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

What we seal

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

What fire rated sealant looks like in Alresford

If you run a hotel, guest house or holiday let in a coastal place like Alresford, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

If you look after a building such as Alresford Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Saint Andrew's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
