Fire stopping for commercial buildings in Ash Green
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with unsealed joints where partitions meet the slab and fire stopping installed outside its tested range, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Ash Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Ash Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee is for workmanship rather than 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.

Common problems we fix in Ash Green
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. Over a few years of fit-outs, a wall can collect a lot of these.
If one of these sounds familiar, it’s time for a closer look:
- Head-of-wall gaps with no fire seal
- Hidden openings found during inspections
- Penetration schedules that need working through
- Unsealed openings around new pipes and cables
For a hospital such as Guildford Hospital (4.2 miles east of Ash Green), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
What your quote should include
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Can the work be phased to keep areas open?
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Approving the work on behalf of building control
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Joints and surfaces we work on

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- Distance, for remote addresses
- Working within restricted access windows
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
- Asbestos survey details if the building is older

Common questions from Ash Green clients
Is Ash Green too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Does your area include sites such as Belle Vue Enterprise Centre, near Ash Green?
Yes. We cover Ash Green and the area around it, including industrial estates, business parks and retail parks such as Belle Vue Enterprise Centre. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Who decides which product is used?
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.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Why act early in Ash Green
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Halls, stores and units around places like Ash Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Why us?
- Fully insured
- Clear, fixed quotes
- Commercial sealant work since 2005
- Products installed to the manufacturer’s instructions
