About our fire stopping in Purleigh
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’d rather say that up front. 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 penetrations discovered above suspended ceilings and seals that don’t match their tested detail, we can put it right, whatever the surface. Looking for mastic applicators who cover Purleigh? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places like Purleigh, 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.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Purleigh, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Send your site hours and access windows
- Make sure the joints can be reached

When to call us in Purleigh
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
These are often picked up first by site or facilities staff:
- Open linear gaps along the top of fire-resisting walls
- Fire sealant pulled out of the opening
- Snag lists that include open service penetrations
- Expanding foam used as fire stopping
For a school such as Purleigh Community Primary School, penetration sealing fits best at the end of the summer works.

What else we do in Purleigh
Cost factors for service penetrations
The price varies from site to site. Expect it to depend on:
- Induction, permit and paperwork requirements
- How much existing material needs removing
- Access and working height
- The product specified
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Any specification or named product
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- The postcode of the building
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
FAQs: Purleigh
Would you work within a site like St Peter's Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Wycke Hill Business Park, close to Purleigh?
Yes. Our area takes in Purleigh and its surroundings, with estates and business parks such as Wycke Hill Business Park included. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you design or specify fire stopping?
No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you cover Purleigh?
Yes. We cover Purleigh and the rest of Essex, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email a schedule or drawings.
After the work
Keep the joints in good shape with a few simple steps:
- Put resealing into every M&E and fit-out package
- Keep product data and details in the fire safety file
- Agree the fire-stopping specification before services go in
- Foam or ordinary sealant is never a fire-seal repair
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Fire-rated sealing for Purleigh buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. Purleigh lies roughly 35 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
On a hospital site such as St Peter's Hospital, which lies north of Purleigh, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a building at a site such as Wycke Hill Business Park, 2.2 miles north of Purleigh, a check of penetration seals after each fit-out is good practice.
Purleigh is about 3 miles south of Maldon, in Essex. Anywhere in CM3, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 644 places across Essex fall within our area, including Purleigh. Sites around London have their own page, about 35 miles away.
