Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. 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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Fire stopping in Send Marsh
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you are dealing with old intumescent sealant that has split away and head-of-wall gaps with no fire seal, we can put it right, on linear gaps at wall heads, service gaps in risers and pipe penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Send Marsh is the same: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Send Marsh often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common problems we fix in Send Marsh
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Typical triggers for a call:
- Snag lists that include open service penetrations
- Unsealed joints where partitions meet the slab
- Non-fire-rated filler around services
- Fire seals cut back for extra cables and never reinstated
Residences at universities like University of Surrey - Stag Hill Campus, 4.7 miles south-west of Send Marsh, have compartment walls that must be resealed whenever services change.

What the job involves on each surface
Drylining partitions
Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Common questions from Send Marsh clients
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Send Marsh?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is a hospital such as Woking Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is Send Marsh in your area?
Yes. We take on work across Send Marsh, with one number for every area we cover.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

What else we do in Send Marsh
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Look above ceilings when tiles are lifted for other jobs
- Settle who seals which penetrations at the start of a project
- Have penetrations checked while they can still be seen
- Record which product was used where
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.

Central London is about 23 miles from Send Marsh. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.

For a site team at a college like Woking College (2 miles north-west of Send Marsh), fire-rated sealing is best scheduled after the summer works.

Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit.

If others near Send Marsh need work, visits can be combined. A fixed quote is given before anything starts.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready

Advice
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
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
