Fire stopping near Lower Bourne

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 Lower Bourne

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 01277 525 020 or send details through our quote form with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you have builders’ foam or ordinary silicone in compartment walls and unsealed openings around new pipes and cables, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lower Bourne is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Lower Bourne, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Lower Bourne

Before we quote, we look at:

  • Phasing around occupants
  • How much there is to seal
  • Access and working height
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Clear photos of the problem areas
  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or send details through our quote form to discuss it first.

Why it’s worth doing now in Lower Bourne

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • Commercial sealant work since 2005
  • Our applicators hold CSCS cards
  • Public liability insurance in place
  • 12 months’ guarantee on every job

What the job involves on each surface

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Issuing fire ratings or certificates for seals
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Deciding what a wall or floor needs, which belongs to the designer

If you’re not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Where we work in Lower Bourne

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

FAQs: Lower Bourne

Does your area include sites such as Hookstile Trading Estate, near Lower Bourne?

Yes, sites like Hookstile Trading Estate are within our area, along with the rest of Lower Bourne. Send details of the unit and the work through our quote form for a quick quote.

Is hospital work, at somewhere like Farnham Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is sealant suitable for all service openings?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is Lower Bourne in your area?

Yes. We cover Lower Bourne, and you can call 01277 525 020 or email drawings and photos to get started.

Do you design or specify fire stopping?

No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it, and tell you if a detail needs another product.

Do you approve fire stopping for building control?

No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used, and you can tell us what other records you need at quote stage.

Service penetrations in Lower Bourne buildings

Fire stopping of openings and penetrations in England falls under Approved Document B.

Our part stays the same: the specified product, installed to its tested detail. Lower Bourne has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Shop fits in centres such as Farnham Retail Park, 1.5 miles north of Lower Bourne, can bring new services through fire-resisting walls between units, which then need the specified seal.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in Lower Bourne is a clear list of what needs doing. You’ll then get a fixed price for the work.

  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. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Share your working hours and any access restrictions
  • Make sure the joints can be reached
  • Let building users know which areas are affected

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Signs you need fire stopping in Lower Bourne

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

These are often picked up first by site or facilities staff:

  • Penetration schedules that need working through
  • Open linear gaps along the top of fire-resisting walls
  • Unsealed penetrations discovered above suspended ceilings
  • Fire-rated sealant that has cracked or shrunk back

Hospital estates such as Farnham Community Hospital, 1.7 miles north of Lower Bourne, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What to look for in a quote

  • Proof of insurance
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it
