Fire stopping across Mickleham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Fire stopping in Mickleham, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve fire-stopping items raised at inspection or handover and fire stopping installed outside its tested range, across cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows. For commercial sealant work in Mickleham, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a smaller site near Mickleham, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

How the quote is worked out

What shapes the price:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • The size and state of each joint
  • Any access equipment needed

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • Clear photographs of the problem areas
  • The postcode of the building

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.

Why it’s worth doing now in Mickleham

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Older rural buildings around Mickleham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Compartment walls and floors in Mickleham

Mickleham lies roughly 19 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. The area within 2 miles of Mickleham holds several hotels. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

For a unit at a site such as Leatherhead Industrial Estate, 1.9 miles north of Mickleham, new power or data runs between office and warehouse can breach a compartment wall. Hotels such as Burford Bridge Hotel, 1.1 miles south of Mickleham, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Mickleham is about 2 miles south of Leatherhead, in Surrey. Across the RH5 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 379 places in Surrey, large and small. For work in that direction, see our London page, about 19 miles away.

If you need fire stopping in RH5, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Old London Road, School Lane and Dell Close or close by, send details and we will quote for service penetrations. Nearby places we also cover include Westhumble (1 mile south-west), Leatherhead (2 miles north), Pixham (2 miles south), Fetcham (2 miles north-west) and Great Bookham (2 miles west). Further afield, our area takes in Guildford (11 miles west), Woking (11 miles west), Epsom (5 miles north-east), Horley (9 miles south-east), Redhill (7 miles east) and Ewell (6 miles north-east).

Mickleham: questions and answers

Do you take on work at healthcare sites like Leatherhead Community Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Leatherhead Industrial Estate, by Mickleham?

Yes. We cover Mickleham and the area around it, including industrial estates, business parks and retail parks such as Leatherhead Industrial Estate. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you seal any opening with fire-rated sealant?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution, as set out by the designer.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Which standards are fire seals tested to?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

Common problems we fix in Mickleham

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Site and facilities staff are often the first to spot these:

  • Openings found when ceilings come down for a refit
  • Fire stopping installed outside its tested range
  • Service penetrations left open after M&E works
  • Unsealed joints where partitions meet the slab

Wherever services are added at a hospital such as Leatherhead Community Hospital (to the north of Mickleham) the compartment line has to be made good with the specified product.

Before you book anyone

  • Their approach to joint depth and backing
  • Whether their applicators hold CSCS cards
  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

Surface by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We confirm material and size first and tell you if sealant isn’t the right product.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Mickleham may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements
