Leave it or put it right?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Older rural buildings around Finstock move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Fire stopping for commercial buildings in Finstock
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. If you’re dealing with builders’ foam or ordinary silicone in compartment walls and damaged fire seals in risers and voids, we can put it right, whatever the surface. A single leaking joint is often how a building in Finstock first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A job near Finstock is usually planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out in Oxfordshire comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send photos by email and we will arrange a return visit.

Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Rural sites near Finstock may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use
- Clear stock, furniture or equipment away from the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Advice
Fire-rated sealing for Finstock buildings
At about 64 miles from central London, Finstock is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
For a building such as Church of the Holy Trinity, new heating or data runs are the usual reason penetrations need sealing. For a school such as Finstock Church of England Primary School, penetration sealing fits best at the end of the summer works. Offices at parks like Manor Barns Business Park (to the north of Finstock) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Finstock is about 4 miles north of Witney, in Oxfordshire. We send applicators to Finstock for service penetrations, handled exactly as we handle every other area. Finstock is one of 423 places we cover in Oxfordshire. We also cover Oxford, around 12 miles from Finstock.

Different surfaces, different methods
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance, including keys, permits and any isolations.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- The site’s rules and procedures
- Which sealant the job calls for
- How accessible the joints are
- Travel to remote or island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- The asbestos register, for older buildings
- Anything awkward about access or site hours
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or email drawings and photos.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Your questions answered
Do you cover business parks and estates near Finstock, such as Manor Barns Business Park?
Yes. Estates, retail parks and business parks around Finstock, Manor Barns Business Park among them, are all within reach. Photos and a short description are enough for a first look.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Finstock?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
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 hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you work while the building is occupied?
Typically, yes. Phased work can be planned so areas stay in use.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
