Keeping the joints in good condition

Looking after new joints is easy:

  • Check whether a sealant can be painted before decorating over it
  • Look in service cupboards and ceiling voids from time to time
  • Keep photos of seals that will be hidden
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Fire rated sealant in Adstock, done properly

Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. Typical jobs include open gaps behind door architraves and open joints along the top of partitions, on linear gaps, door frames and pipe & cable gaps.

Somewhere as small as Adstock, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Fire rated sealant around Adstock

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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

For site and facilities teams at buildings such as Padbury Church of England School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Cecilia, gaps around pipes and cables are worth checking after any building work there.

Quotes for fire rated sealant in Adstock

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises
  • Any mould that needs treating

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Whether it’s a home or a business
  • The address or postcode of the job
  • How many joints, rooms or windows are involved
  • Access, such as stairs, a lift or height

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or email us.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

  • Openings too large for sealant, which need batts, boards or another system
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Do you cover smaller places like Adstock?

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

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

What do you need from me for a quote?

Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

How long will you be here?

A typical job takes a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.

Can new sealant go over the old?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

Can you work in occupied buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

What we do, step by step

We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Adstock needs a little journey planning: 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 start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  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.

Preparing for the visit

  • Tell us if parking is tricky
  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints

What the job involves on each surface

Door frames

Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist and we’ll mention anything we notice.

Linear gaps

Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.

Why it’s worth doing now in Adstock

Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Around Adstock, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.
