Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Bordon is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Point out parking and an unloading spot
Quotes

Advice
Fire stopping for commercial buildings in Bordon
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors, and what we are called in for most is fire seals cut back for extra cables and never reinstated and snag lists that include open service penetrations. Most enquiries from Bordon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In places the size of Bordon, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions about Bordon
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Bordon?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you cover business parks and estates near Bordon, such as Woolmer Trading Estate?
Yes. We cover Bordon and the area around it, including industrial estates, business parks and retail parks such as Woolmer Trading Estate. A few photographs and the unit address let us price the work.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What do you charge?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Openings that need collars, wraps, batts or boards rather than sealant
- Fire doors, dampers or other fire safety equipment
- Walls or floors that aren’t fire-resisting to begin with
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
What we seal
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
Quoting for work in Bordon
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The size and state of each joint
- Access and working height
- The total length or number of joints
- Which sealant the job calls for
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Any dates the work must fit around
- The site address and postcode
- How the joints are reached, and at what height
- Any specification or named product
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Check risers and ceiling voids after each round of works
- Keep product data and details in the fire safety file
- Check with the data sheet before painting over fire sealant
- Put resealing into every M&E and fit-out package
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job.
Work for main contractors and building owners
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

How the job changes by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
Fire stopping in Bordon: the local picture
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. We install whatever has been specified, to the product’s tested detail. Central London is about 43 miles from Bordon. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.
Large healthcare estates like Chase Hospital (0.5 miles south of Bordon) change their services often, so penetration seals are worth checking after M&E work. Where a unit on an estate such as Woolmer Trading Estate (under half a mile south of Bordon), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Holiday works at schools like Bordon Infant School often leave service openings to seal before pupils return.
Bordon is about 10 miles south-west of Aldershot, in Hampshire. Across the GU35 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.
