Fire stopping in Newdigate, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, phone 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. Most enquiries involve fire sealant pulled out of the opening and fire seals cut back for extra cables and never reinstated, across cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. A single leaking joint is often how a building in Newdigate first comes to us: we look at the rest while we’re there and tell you what we find.
For a smaller site near Newdigate, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Different surfaces, different methods
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Fire stopping around Newdigate: how the place shapes the job
At about 24 miles from central London, Newdigate is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail.
Theatres, wards and plant rooms at sites like Langley Green Hospital (to the south-east of Newdigate) all have compartment walls crossed by services. Halls and meeting rooms at places like Church of St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal.
Newdigate is about 5 miles south of Dorking, in Surrey. Anywhere in RH5, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Surrey, 379 places are covered, Newdigate among them. For work in that direction, see our London page, about 24 miles away.
Business premises anywhere in RH5 are within our area for service penetrations.

We also cover Cudworth (1 mile east), Parkgate (1 mile north-east), Shellwood Cross (2 miles north), Russ Hill (2 miles south-east) and Nalderswood (3 miles north-east) for service penetrations. A short drive away, we cover Guildford (14 miles north-west), Epsom (12 miles north), Horley (5 miles east), Redhill (7 miles north-east), Ewell (13 miles north) and Reigate (6 miles north-east).
Around Newdigate
Around Newdigate, our work takes us to commercial buildings near Six Bells pub and Newdigate Brickworks, among other places. Newdigate’s nearest station is Holmwood station, about 1.7 miles north-west of the centre. Nearby you will also find Langley Green Hospital (4.9 miles south-east) and Betchworth Castle (4.9 miles north). For a walk, there’s Leith Hill and Vann Lake.
Should maintenance staff do it?
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common questions from Newdigate clients
Can you work on a hospital site such as Langley Green Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Newdigate off your patch?
Not at all. Newdigate is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Reviewing a building’s overall fire safety
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Newdigate may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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.
- 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.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Send any specification or drawings in advance
- Let us know about inductions and permits
- Make sure the joints can be reached

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- How much existing material needs removing
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- The total length or number of joints
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Anything awkward about access or site hours
- The postcode of the building
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or email us.
Common problems we fix in Newdigate
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.
Look out for the following:
- Unsealed openings around new pipes and cables
- Expanding foam used as fire stopping
- Openings found when ceilings come down for a refit
- Fire-stopping items raised at inspection or handover
Holiday works at schools like Newdigate CofE Endowed Aided Infant School often leave service openings to seal before pupils return.
What your quote should include
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
