Common questions in Saunderton

Will you come out to Saunderton?

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

Do you work for landlords with property near Saunderton station?

Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Do the sealants smell?

Possibly a little. It fades as the sealant cures.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. We use whichever the specification and tested details call for.

Can you work in occupied buildings?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.

Do you guarantee your work?

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

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Where are you based?

We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

How we handle fire rated sealant in Saunderton

Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on, gap by gap. We’re often asked to deal with gaps flagged on a fire risk assessment and gaps filled with a product that isn’t fire-rated, across pipe & cable gaps, linear gaps and service penetrations.

For holiday lets, converted business premises or a community building near Saunderton, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

All our work is covered by a one-year guarantee.

Common problems we fix in Saunderton

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

Look out for any of the following:

  • Open gaps behind door architraves
  • Old fire sealant that has split or come away
  • Linear gaps at the head of walls
  • Holes left by a change of layout

Rented homes near Saunderton station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What your quote should include

  • How the joint is cleaned and prepared
  • What product goes in the joint

Choosing a sealant specialist

Landlord and commercial work in Saunderton

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Sign-off of the building, which sits with building control or your assessor
  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system

If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

Where we work in Saunderton

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

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Get damaged fire seals looked at promptly
  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks
  • Tell trades working in the building that fire seals must be put back

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Commercial buildings in Saunderton

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.

Managing a site like Bledlow Ridge School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Paul, gaps around pipes and cables are worth checking after any building work there.

Surface by surface

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the seal has something sound to bond to.

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.

How it works

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Saunderton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. Old, damaged or unsuitable sealant is removed.
  3. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before

Advice

What happens if it’s left?

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In a small place like Saunderton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
