Fire stopping for businesses in Tilford

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle fire stopping in Tilford

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you have hidden openings found during inspections and non-fire-rated filler around services, we can put it right, on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations alike. Looking for mastic applicators who cover Tilford? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Barn and farm-building conversions near places like Tilford often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Tilford: questions and answers

Could you schedule work at a campus like University for the Creative Arts for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Will you take on work at estates like The Sands Business Centre, close to Tilford?

Yes. We cover Tilford and the area around it, including industrial estates, business parks and retail parks such as The Sands Business Centre. Send details of the unit and the work through our quote form for a quick quote.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What does an EI 60 rating mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. The rating applies to the product as tested.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Around Tilford, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why us?

  • CHAS accredited contractor
  • Constructionline member for supplier checks
  • Commercial sealant work since 2005
  • One number for every site we cover

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Ask which product is in place before decorating
  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Tilford are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Share the asbestos register for older buildings
  • Agree which areas must stay open
  • Let us know about inductions and permits

Quotes

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Advice

Fire-rated sealing for Tilford buildings

In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 35 miles from Tilford. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Halls and meeting rooms at places like Church of All Saints sometimes gain new services, and any compartment wall crossed needs the specified seal. At a university such as University for the Creative Arts, 3.2 miles north-west of Tilford, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Tilford is about 3 miles south-east of Farnham, in Surrey. Our applicators travel to Tilford for work on service penetrations, handled exactly as we handle every other area.

What we are called out for in Tilford

Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

What tends to prompt an enquiry:

  • Fire sealant pulled out of the opening
  • Fire stopping installed outside its tested range
  • Openings found when ceilings come down for a refit
  • Fire-stopping items raised at inspection or handover

In a retail centre such as Farnham Retail Park, 2.6 miles to the north-west of Tilford, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.

What your quote should include

  • Health and safety accreditation such as CHAS
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • What level of public liability insurance do they hold?
