Fire stopping in Springhead
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or use the quote form with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you are dealing with non-fire-rated filler around services and fire sealant pulled out of the opening, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Springhead is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Buildings in a smaller place such as Springhead that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Questions we are asked in Springhead
Is hospital work, at somewhere like Gravesham Community Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Ebbsfleet Business Park, near Springhead, within your area?
Yes, sites like Ebbsfleet Business Park are within our area, along with the rest of Springhead. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What do you charge?
Each job is quoted on its own details. For yours, call the office on 01277 525 020 or send details through our quote form with a description of the work.
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.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.

Other services in Springhead
Surface by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones normally call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.
Building owners, agents and FMs in Springhead
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.

Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For a site in Springhead, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
Preparing the site
- Tell us which areas need to stay in use
- Flag any permit to work we will need
- Have the specification and drawings to hand

Advice
Where services cross fire walls in Springhead
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Central London is about 19 miles from Springhead. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.
Tenant changes at centres like Imperial Retail Park, 1.7 miles north-east of Springhead, often mean new services through walls between units. Residences at universities like University of Greenwich, 2.7 miles west of Springhead, have compartment walls that must be resealed whenever services change. Theatres, wards and plant rooms at sites like Gravesham Community Hospital, 1.8 miles north-east of Springhead, all have compartment walls crossed by services.
Springhead is about 1 mile west of Northfleet, in Kent. We cover commercial sites throughout Springhead. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, about 19 miles away.
Commercial sites across DA11, DA10 and DA13 are covered for service penetrations. Buildings on Gwynn Road, Fleet Road and Roman Road are within our area. You’ll find Springhead on or near the A2, so getting applicators and materials to site is simple. Just outside Springhead, we also work in Painters Ash (1 mile south-east), Northfleet (1 mile east), Northfleet Green (1 mile south), Betsham (1 mile south-west) and Ebbsfleet Valley (1 mile west). A short drive away, we cover Maidstone (14 miles south-east), Dartford (5 miles west), Sevenoaks (12 miles south-west), Swanley (7 miles west), Kings Hill (11 miles south) and Foley Park (14 miles south-east).
Around Springhead

The closest station to Springhead is Ebbsfleet International station, about 0.9 miles north of the centre. A little further out are Bluewater (2.5 miles west) and Gravesham Museum (2 miles north-east). Green spaces nearby include Chafford Gorges Nature Park and Sawyers Lake.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Settle who seals which penetrations at the start of a project
- Flag new cables with no seal around them
- Have penetrations checked while they can still be seen
- File the specified details where the next contractor can find them
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.
