Quoting for work in Horley
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- Phasing around occupants
- How much there is to seal
- Distance, for remote addresses
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- When you need the work done
- The asbestos register, for older buildings
- The type of building and who uses it
- Anything awkward about access or site hours
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
About our fire stopping in Horley
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and what we’re called in for most is seals disturbed by maintenance and left open and fire sealant pulled out of the opening. Looking for mastic applicators who cover Horley? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In a town like Horley, penetration seals typically need attention after other trades have been through. A check after services work is sensible; tell us what the specification says and we will install to it.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Where services cross fire walls in Horley
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Horley lies roughly 22 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
For a building such as St Wilfrid's Church, new heating or data runs are the usual reason penetrations need sealing. For a building at a site such as Gatwick Business Park, which lies south-west of Horley, a check of penetration seals after each fit-out is good practice.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Horley can form part of a wider programme.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Town-centre premises in Horley may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send your site hours and access windows
- Let building users know which areas are affected

When to call us in Horley
Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access typically bring them to light.
Things that normally lead to an enquiry:
- Unsealed openings around new pipes and cables
- Head-of-wall gaps with no fire seal
- Fire stopping installed outside its tested range
- Penetration schedules that need working through
On a hospital site such as Spire Gatwick Park Hospital (Private) (1 mile south-west of Horley), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Questions to ask before you book
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
- What site paperwork they can supply

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.
Why act early in Horley
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. In a town such as Horley, a lot of buildings are older and have been altered over time, and joints where old meets new tend to fail first. Resealing them early protects the building behind.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Do you design or specify fire stopping?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Do you certify or sign off fire stopping?
