Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
About our fire stopping in The Sands
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. Those on your schedule are closed with the specified product. If you have openings found when ceilings come down for a refit and penetration schedules that need working through, we can help. Looking for mastic applicators who cover The Sands? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
A job near The Sands is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Signs you need fire stopping in The Sands
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Most enquiries start with one or more of the following:
- Seals disturbed by maintenance and left open
- Fire stopping installed outside its tested range
- Unsealed joints where partitions meet the slab
- Openings left by services added after handover
Wherever services are added at a hospital such as Farnham Community Hospital, 2.1 miles to the west of The Sands, the compartment line has to be made good with the specified product.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Have penetrations checked while they can still be seen
- Ask the designer to confirm details early on refits
- Treat an open penetration as a priority repair
- Don’t let anyone top up a fire seal with the wrong product
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Fire stopping in The Sands: the local picture
The Sands is about 34 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. 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. We install whatever has been specified, to the product’s tested detail.
For a unit at a centre such as Farnham Retail Park, 2 miles west of The Sands, penetration seals are worth checking after each shop fit. Colleges such as Aldershot College (to the north of The Sands) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.
Surfaces we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers

- Pipe penetrations

FAQs: The Sands
Is The Sands Business Centre, near The Sands, within your area?
Yes. Estates, retail parks and business parks around The Sands, The Sands Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Would you work within a site like Farnham Community Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Are you members of a third-party fire-stopping installer scheme?
No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them. Where it isn’t required, we install the specified sealant to the maker’s details.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For a building around The Sands, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints
