What affects the quote in Shenfield

We don’t publish a price list, because jobs vary so much. The quote depends on:

  • When we can work, for business premises
  • The type of sealant required
  • How many areas need sealing
  • Access and height

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • Any access issues, like height or stairs
  • The problem you’ve noticed
  • Where the job is, and your postcode
  • The rough size of the job

How we handle fire rated sealant in Shenfield

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, one gap at a time. We work on linear gaps, pipe & cable gaps and service penetrations, and common reasons people get in touch are fire stopping disturbed by later work and unsealed gaps around fire door frames.

For a pub, café, guest house or shop in or near Shenfield, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

Big or small, it’s backed by our one-year guarantee in Shenfield and across Essex.

What fire rated sealant looks like in Shenfield

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

If you look after a building such as Shenfield St. Mary's Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like Church of St Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What sealant work cannot fix

We will always be straight with you, so here’s what new sealant won’t do:

  • Sign-off of the building, which sits with building control or your assessor
  • Construction that does not provide fire resistance on its own
  • Fire doors that need new seals, closers or hardware

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

Joints and surfaces we work on

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

Do you need fire rated sealant in Shenfield?

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

If you can see any of these, it’s time to have the joints looked at:

  • New service routes left unsealed after building work
  • Seals cut through by electricians, plumbers or data installers
  • Fire seals that have cracked with movement
  • Unsealed gaps around fire door frames

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

Choosing a sealant specialist

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Leave it or put it right?

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. In a smaller place like Shenfield, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.

What you get with us

  • An ARBOMaster approved applicator
  • Neat joints and a tidy finish
  • A 12-month guarantee on all work
  • Quality sealants from Arbo and Everbuild

FAQs for Shenfield

Do you work for landlords with property near Shenfield station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.

Can you do fire rated sealant in Shenfield?

Yes. Our work covers London and the South East, and Shenfield is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.

Can you tell me which gaps need fire stopping?

No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Can you work in occupied buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

Will the old sealant be removed?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

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

Size, access and the old material all affect the cost. Call for a quick quote.

What the job involves on each surface

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.

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 the locations noted.

How it works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. A visit to Shenfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Mention if the joints have been sealed before
  • Tell us about any water getting in
