Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Frensham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Where the detail needs backing, it goes in at the stated depth.
- 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.
Preparing the site
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Advice
How we handle fire stopping in Frensham
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations, and the failures we’re asked to look at most are non-fire-rated filler around services and fire seals cut back for extra cables and never reinstated. A single leaking joint is often how a building in Frensham 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 Frensham is usually planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
Cost factors for service penetrations
Quotes vary with the job. It mainly depends on:
- The site’s rules and procedures
- Travel to remote or island sites
- Removal of failed or old sealant
- Working within restricted access windows
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Specification clauses that apply
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, ring 01277 525 020 or use the quote form.
How the job changes by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Ask the designer to confirm details early on refits
- Check risers and ceiling voids after each round of works
- Ask which product is in place before decorating
- Foam or ordinary sealant is never a fire-seal repair
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
Your questions answered
What happens to BS 476 references for fire stopping in Frensham?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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.
Can work at a site such as University for the Creative Arts fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
What will the job cost?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
Doing it in-house
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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.
Service penetrations in Frensham buildings
At about 38 miles from central London, Frensham 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. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Industrial units on estates such as Grovebell Industrial Estate, 2.7 miles to the north-west of Frensham, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Hotels like Frensham Pond Hotel & Spa, 1 mile south of Frensham, are refurbished in phases, and each phase can open up compartment walls. Residences at universities like University for the Creative Arts, 3.5 miles north of Frensham, have compartment walls that must be resealed whenever services change.
