Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Issuing fire ratings or certificates for seals
- Plastic pipes whose detail calls for a collar or wrap
- Fire risk assessments, a job for a competent assessor
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.
Where we work in Woolstone

- Linear gaps at wall heads
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Fire stopping in Woolstone, done properly
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. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with snag lists that include open service penetrations and damaged fire seals in risers and voids, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Woolstone is the same: the right product in a properly prepared joint.
Converted and extended buildings around places like Woolstone can mix old and new construction, 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.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Penetration seals near Woolstone
Woolstone is part of, or right next to, Milton Keynes, which was built as a planned town. Offices and public buildings from that era have typically had several generations of new services, and every change can breach a fire-resisting wall. The 2 miles around Woolstone include three care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Campus buildings at universities such as University of Bedfordshire Milton Keynes Campus (1.5 miles west of Woolstone) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Colleges such as Milton Keynes College, 1.5 miles to the south-west of Woolstone, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Woolstone is about 1 mile west of Middleton, in Milton Keynes.

What else we do in Woolstone
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Questions about Woolstone
Is Woolstone off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
What happens to BS 476 references for fire stopping in Woolstone?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Cost factors for service penetrations
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Distance, for remote addresses
- Phasing around occupants
- How accessible the joints are
- The total length or number of joints
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.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- The asbestos register, for older buildings
- The type of building and who uses it
- The site address and postcode
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email the details over to discuss it first.
Common problems we fix in Woolstone
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
If one of these sounds familiar, it’s time for a closer look:
- Old intumescent sealant that has split away
- Head-of-wall gaps with no fire seal
- Non-fire-rated filler around services
- Openings found when ceilings come down for a refit
Large healthcare estates like Milton Keynes University Hospital, 1.3 miles south of Woolstone, change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- How they handle RAMS and site documents
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
Keeping the joints sound
For the best life from the joints:
- Arrange inspection before areas are covered up
- Flag new cables with no seal around them
- Ask the designer to confirm details early on refits
- Keep product data and details in the fire safety file
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
On site: what to expect
On arrival, 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 any cutting starts, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. Work in places the size of Woolstone is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Warn occupants and staff about the work
- Send any specification or drawings in advance
- Flag any permit to work we’ll need

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