FAQs for Newton Valence

Do you cover smaller places like Newton Valence?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I let a flat near Alton station. Can you help?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.

Do you have insurance?

Yes, we are fully insured.

Fire rated sealant in Newton Valence

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you’re dealing with standard silicone or caulk in a fire-stopping gap and door frames with gaps between frame and wall, we can help, on pipe & cable gaps, flats & HMOs and service penetrations alike.

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

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens on the day

You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. For a village or hamlet like Newton Valence, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

Preparing for the visit

  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on

Advice

Keeping the joints in good condition

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

  • Include fire stopping when you schedule refits
  • Check whether a sealant can be painted before decorating over it
  • Take photos of fire stopping before ceilings or boxing go back
  • Keep the record of products and locations with your fire safety documents

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.

Why deal with it now?

A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In a small place like Newton Valence, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • An ARBOMaster approved applicator
  • Over 20 years’ experience
  • Every job guaranteed for a year
  • Full insurance on every job

Workplaces and buildings in Newton Valence

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

If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.

10 questions to ask before you book

Surface by surface

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

How we quote for fire rated sealant

There’s no set price list, because no two jobs are the same. What we look at:

  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint
  • Whether there’s mould to deal with
  • The number and length of the joints

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode
