When to call us in Cudham
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
Clients usually get in touch after noticing one or more of the following:
- Damaged fire seals in risers and voids
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
Access in Cudham needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- Proof of insurance
- Who will actually carry out the work
About our fire stopping in Cudham
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. Site teams most often ask us about damaged fire seals in risers and voids and open linear gaps along the top of fire-resisting walls, across joints between fire-resisting walls and floors, cable penetrations and service gaps in risers. Looking for mastic applicators who cover Cudham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
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.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- 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.
Getting the site ready
- Have the specification and drawings to hand
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
Cost factors for service penetrations
Your fixed quote is built from the real scope. It takes account of:
- The total length or number of joints
- Whether the work must be split into stages
- Any access equipment needed
- Site requirements such as inductions and permits
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- The type of building and who uses it
- A wide shot and a close-up of the area
- The postcode of the building
- The asbestos register, for older buildings
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or email us.

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Fire stopping in Cudham: the local picture
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system. Fire stopping of openings and penetrations in England falls under 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. What we install is set by the specification, and it goes in to the tested detail.
For a building such as Church of St Peter and St Paul, new heating or data runs are the usual reason penetrations need sealing. Holiday works at schools like Cudham Church of England Primary School often leave service openings to seal before pupils return.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Fire risk assessments, a job for a competent assessor
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
Surfaces we seal
- Small duct penetrations where the tested detail allows

FAQs: Cudham
Do you cover business parks and estates near Cudham, such as Biggin Hill Airport Trading Estate?
Yes. Estates, retail parks and business parks around Cudham, Biggin Hill Airport Trading Estate among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you take on jobs in Cudham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
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’ll confirm the colours available for the specified product.
What do BS EN 1366-3 and BS EN 13501-2 mean?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. The rating applies to the product as tested.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
