Fire stopping in Stonehill, done properly
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve head-of-wall gaps with no fire seal and unsealed openings around new pipes and cables, on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations. Looking for mastic applicators who cover Stonehill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Smaller places such as Stonehill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Our workmanship is guaranteed for 12 months, in Stonehill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

How the quote is worked out
To price the job, we consider:
- Quantities, in metres or numbers
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
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 and we will explain how it’s made up.
Details that help us quote
We can often quote from photos and a few details. It helps to include:
- Any dates the work must fit around
- How the joints are reached, and at what height
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email a schedule or drawings.
Where services cross fire walls in Stonehill
In England, Approved Document B covers fire stopping of 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. Our part stays the same: the specified product, installed to its tested detail. Stonehill is about 22 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Campus buildings at universities such as Royal Holloway University, 4.3 miles to the north of Stonehill, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. In a retail centre such as Lion Retail Park (2.9 miles south of Stonehill), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Stonehill is about 3 miles north of Woking, in Surrey. We cover commercial sites throughout Stonehill, whether it’s a single job or part of a planned programme. Stonehill is one of 379 places in Surrey on our list. Our Reading page has more on work in that area.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
Where we work in Stonehill
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. Smaller jobs around Stonehill can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Related advice
Stonehill: questions and answers
Could you schedule work at a campus like Royal Holloway University for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Stonehill too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Common problems we fix in Stonehill
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. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Things that usually lead to an enquiry:
- Fire-stopping items raised at inspection or handover
- Unsealed joints where partitions meet the slab
- Non-fire-rated filler around services
- Seals disturbed by maintenance and left open
On a hospital site such as St Peter's Hospital, 1.7 miles north-east of Stonehill, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
What your quote should include
- Will CSCS-carded applicators be on site?
- How the joint faces will be prepared and primed
- Will failed sealant be removed rather than covered?
- How they’ll work around occupants
Leave it or put it right?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. Converted and older buildings near places like Stonehill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Maintenance after handover
For the best life from the joints:
- Include service cupboards in routine inspections
- Treat an open penetration as a priority repair
- Get seals inspected before ceilings and boxing close
- Foam or ordinary sealant is never a fire-seal repair
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. Details can then be picked to suit the actual pipes, cables and ducts.
