Fire rated sealant in Terriers

How we quote for fire rated sealant

The price is agreed before any work begins. It takes into account:

  • Any working-time requirements on site
  • The product the joint needs
  • How easy the joints are to reach
  • How much old sealant there is and how hard it is to remove

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Helping us quote

What to tell us when you ask for a quote:

  • If it’s domestic, commercial or a hotel
  • If someone has resealed it before
  • The rough size of the job
  • A few photos by email, if you can

For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before any work starts.

Fire rated sealant in Terriers, done properly

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. If you have ordinary sealant used where a fire-rated product was needed and holes left by a change of layout, we can put it right, on plasterboard & masonry, flats & HMOs and service penetrations alike.

Around a place like Terriers, 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, in Terriers and everywhere else we cover.

Commercial buildings in Terriers

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 are given, installing the product to its tested details. Terriers has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

For landlords with property near High Wycombe station, any gap left by new services in shared walls should be closed with a fire-rated product. Schools such as The Royal Grammar School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Terriers is about 1 mile north-east of High Wycombe, in Buckinghamshire. Our applicators cover fire rated sealant for homeowners, landlords and businesses in Terriers, as part of our work across Buckinghamshire.

Signs you need fire rated sealant in Terriers

A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The most common problems we see are:

  • Holes left by a change of layout
  • Joints picked up in a fire-stopping survey
  • Cracked or shrunken fire-rated sealant
  • Open holes round services passing through fire walls

For buildings such as Church of Saint Francis, gaps around pipes and cables are worth checking after any building work there.

What your quote should include

  • How long to leave it before use
  • Who turns up on the day
  • Is VAT in the price?
  • Are they insured?

How to choose a mastic man

How it works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. A visit to Terriers is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • Move anything stored near the joints

Ask for a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.

Different surfaces, different methods

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.

Door frames

Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details before the trim goes back.

Why deal with it now?

An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Terriers, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Terriers: your questions answered

Do you cover smaller places like Terriers?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work in hotels near Terriers?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Can you fill the gap behind a fire door frame?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

Do you guarantee your work?

Yes. Each job is guaranteed for twelve months, large or small.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Where are you based?

Mr Mastic is based in Crawley. We cover Terriers and the rest of Buckinghamshire, along with the rest of our area.

I’m a tenant. Can you help?

Yes. Check with your landlord; we can send the quote to them too.

Will you assess my building’s fire safety?

No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.

When it isn’t the sealant

To be straight with you, some problems need a different trade:

  • Fire doors that need new seals, closers or hardware
  • Construction that does not provide fire resistance on its own
  • Issuing a fire rating or certificate for a building

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