Fire stopping for Gatton sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle fire stopping in Gatton

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. We work on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are builders’ foam or ordinary silicone in compartment walls and fire-rated sealant that has cracked or shrunk back. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Gatton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Gatton still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Agree the fire-stopping specification before services go in
  • Look above ceilings when tiles are lifted for other jobs

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • The product specified
  • Removal of failed or old sealant
  • Access and working height
  • Quantities, in metres or numbers

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Details that help us quote

However big the job, these details speed things up:

  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • What the building is and how it’s used

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send photos by email.

Surface by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.

Building owners, agents and FMs in Gatton

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Gatton can form part of a wider programme across Surrey.

Your questions answered

Can you seal penetrations in a hotel in Gatton after a refit?

Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.

Can you work on a hospital site such as East Surrey 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.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

How soon can the area be used again?

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.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Gatton may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Service penetrations in Gatton buildings

A number of hotels sit less than 2 miles from Gatton. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.

Tenant changes at parks like Kingsfield Business Centre, 2.1 miles south of Gatton, bring new data and services, and openings through fire-resisting walls need the specified seal. For a building such as St Andrew's Church, new heating or data runs are the usual reason penetrations need sealing. At a college such as Reigate College, which lies south-west of Gatton, checking penetration seals after summer M&E works is good practice.

Gatton is about 2 miles north of Redhill, in Surrey. Our applicators travel to Gatton for work on service penetrations. Our Surrey coverage takes in 379 places, from busy centres to rural villages. For work in that direction, see our London page, about 17 miles away.

Why act early in Gatton

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Halls, stores and units around places like Gatton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.
