Fire stopping in Compton

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

How we handle fire stopping in Compton

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Compton. If you have expanding foam used as fire stopping and hidden openings found during inspections, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Compton, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Compton often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. For a building around Compton, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints

Quotes

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Advice

Why act early in Compton

A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Compton. Send photos of each area and we’ll quote for the lot.

A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Why appoint us

  • Specification-led, product-correct work
  • Fully insured, including public liability cover
  • Commercial sealant work since 2005
  • A Constructionline member, so easy to vet

Your questions answered

Is The Sands Business Centre, near Compton, within your area?

Yes, sites like The Sands Business Centre are within our area, along with the rest of Compton. Photos and a short description are enough for a first look.

Is a smaller place like Compton outside your area?

No. Places such as Compton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do the same rules apply to fire stopping in Scotland?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Approving the work on behalf of building control
  • Writing the fire-stopping specification
  • Reviewing a building’s overall fire safety

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

  • Pipe penetrations
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Cable penetrations
  • Linear gaps at wall heads

Service penetrations in Compton buildings

Compton is about 35 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Two care or nursing homes sit less than 2 miles from Compton. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.

Tenant changes at centres like Farnham Retail Park (to the north-west of Compton) often mean new services through walls between units. Workshops and IT rooms at colleges like Aldershot College (2.5 miles north-east of Compton) are re-serviced often, leaving penetrations to seal. On a site such as The Sands Business Centre (0.8 miles east of Compton), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Compton is about 1 mile east of Farnham, in Surrey. Any commercial site in Compton is covered, whether it’s a single job or part of a planned programme. Compton is one of 379 places in Surrey on our list. We also cover Reading, some 19 miles away.

Commercial sites across GU10 and GU9 are covered for service penetrations. If your site is on Moor Park Lane, Compton Way and Moor Park Way or close by, send details and we will quote for service penetrations. If your building is just outside Compton, we cover Runfold (1 mile east), The Sands (1 mile east), Badshot Lea (1 mile north), Farnham (1 mile west) and Sandy Cross (1 mile north-east). Bigger towns within reach include Guildford (9 miles east), Woking (11 miles north-east), Camberley (9 miles north), Frimley (7 miles north), Haslemere (9 miles south) and Cranleigh (13 miles east).

In Compton, that means premises near Moor Park and Shepherd & Flock pub and the streets around them. The closest station to Compton is Farnham station, roughly 1.3 miles west. Nearby you’ll also find Museum of Farnham (1.8 miles west) and Farnham Castle (1.8 miles west). The countryside around Compton includes Runfold Wood and Culverswell Hill.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Working within restricted access windows
  • The site’s rules and procedures

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Any specification or named product
  • Clear photos of the problem areas
  • Access details, including height
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email us.

What the job involves on each surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
