Common questions from Forest Corner clients

Is Forest Corner too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

What happens to BS 476 references for fire stopping in Forest Corner?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Fire stopping in Forest Corner

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, phone 01277 525 020 or email the details over with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. If you are dealing with seals disturbed by maintenance and left open and hidden openings found during inspections, we can help. Facilities teams, main contractors and managing agents in Forest Corner tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep product data and details in the fire safety file
  • Keep general-purpose fillers away from compartment walls
  • Check with the data sheet before painting over fire sealant
  • Flag new cables with no seal around them

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

When to call us in Forest Corner

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.

What tends to prompt an enquiry:

  • Fire stopping installed outside its tested range
  • Expanding foam used as fire stopping
  • Fire seals cut back for extra cables and never reinstated
  • Fire-stopping items raised at inspection or handover

For a building such as St John the Baptist, new heating or data runs are the usual reason penetrations need sealing.

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Who will actually carry out the work
  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Forest Corner may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  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.

Getting the site ready

  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Service penetrations in Forest Corner buildings

There are a number of hotels within about 2 miles of Forest Corner. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

On a hospital site such as St Leonard's Hospital (5.3 miles south-west of Forest Corner), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Holiday works at schools like Poulner Infant School often leave service openings to seal before pupils return.

Forest Corner is about 1 mile east of Ringwood, in Hampshire. Any commercial site in Forest Corner is covered, whether it’s a single job or part of a planned programme. Across Hampshire, 723 places are covered, including Forest Corner. We also cover Southampton, around 16 miles from Forest Corner.

If you need fire stopping in BH24, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Streets here include Burcombe Lane, St Aubyns Lane and Picket Hill, and sites on any of them can send details for a fixed quote. We also cover Foulford (1 mile south-east), Shobley (1 mile north-east), Hangersley (1 mile north-west), Poulner (1 mile west) and Hightown (1 mile south-west).

Around Forest Corner

Why deal with it now?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Halls, stores and units around places like Forest Corner may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why us?

  • Over 20 years of commercial sealing
  • One contact handling all your sites
  • Public liability insurance in place
  • 12 months’ guarantee on every job

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Fire doors, dampers or other fire safety equipment
  • Issuing fire ratings or certificates for seals
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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