Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Openings that need collars, wraps, batts or boards rather than sealant
- Writing the fire-stopping specification
- Approving the work on behalf of building control
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.

How we handle fire stopping in Great Stonar
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and fire-rated sealant that has cracked or shrunk back. Searching for sealant specialists in Great Stonar? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For a smaller site near Great Stonar, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

Why act early in Great Stonar
Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Great Stonar may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. If others near Great Stonar need work, visits can be combined. You will have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- 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.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Point out any areas we must not close
- Move anything stored against the joints
- Tell staff and tenants when we’ll be in

Where services cross fire walls in Great Stonar
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. Either way, we install the specified product to its tested detail. There are several hotels within about 2 miles of Great Stonar. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
On a hospital site such as Ramsgate General Hospital, which lies north-east of Great Stonar, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Tenant changes at parks like Birnham Farm Business Centre, 2.9 miles south-west of Great Stonar, bring new data and services, and openings through fire-resisting walls need the specified seal. Hotels such as The Bell Hotel (to the south of Great Stonar) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Common questions from Great Stonar clients
Do you take on work at healthcare sites like Ramsgate General Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What happens to BS 476 references for fire stopping in Great Stonar?
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. Our part doesn’t change: the specified product, to its tested detail.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Quoting for work in Great Stonar
These are the things that shape the price:
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Approximate linear metres or a joint schedule

- The type of building and who uses it

What else we do in Great Stonar
Different surfaces, different methods
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, along the full length of the run.
