Common questions in Winchmore Hill

Is Winchmore Hill within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Beaconsfield station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.

What should I tell you?

Let us know what needs doing and where. If we need more, we will ask.

Do you carry out fire risk assessments?

No, assessment is not something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame.

Do you hold any approvals?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

What fire rating will the seal have?

Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

How we handle fire rated sealant in Winchmore Hill

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on flats & HMOs, pipe & cable gaps and linear gaps, and the jobs we see most are ordinary sealant used where a fire-rated product was needed and gaps flagged on a fire risk assessment.

For a small place like Winchmore Hill, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant around Winchmore Hill

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.

Schools such as Coleshill Church of England Infant School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Letting a property close to Beaconsfield station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What affects the cost of fire rated sealant

We don’t publish a price list, because no two jobs are the same. What we look at:

  • Whether there’s mould to deal with
  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • How much there is to do

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What we need to know

To make quoting easier, please include:

  • Roughly how big the job is
  • The address or postcode of the job
  • Access, such as stairs, a lift or height
  • The problem you’ve noticed

We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.

Do you need fire rated sealant in Winchmore Hill?

Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.

These are the problems we are asked about most:

  • Gaps flagged on a fire risk assessment
  • New service routes left unsealed after building work
  • Damaged fire sealant left by other trades
  • Standard silicone or caulk in a fire-stopping gap

Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Before you book anyone

  • Is the old sealant removed completely?
  • Is VAT in the price?
  • Which sealant they’ll use, and why
  • Whether they’re fully insured

Choosing a sealant specialist

What sealant work cannot fix

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

  • Walls or floors that weren’t built to resist fire
  • Deciding what fire stopping a building needs
  • Big openings where sealant alone is not the tested solution

If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

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

How it works

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. For a village or hamlet like Winchmore Hill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Before we arrive

  • Clear items away from the joints we are working on
  • Let us know about earlier repairs to the joints
  • Let us know about stairs, lifts or work at height

Getting a quote

Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job and send pictures if you have them.

Related advice

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Do not paint over fire sealant until it has cured
  • Report cracked or damaged seals as soon as you notice them
  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Look in service cupboards and ceiling voids from time to time

Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.

Why deal with it now?

An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. In a small place like Winchmore Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
