Fire stopping in Sidley, done properly
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 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’ll confirm with the quote. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are expanding foam used as fire stopping and fire stopping installed outside its tested range. For commercial sealant work in Sidley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around Sidley, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.

Sidley: questions and answers
Will you take on work at estates like Elva Business Centre, close to Sidley?
Yes. Estates, retail parks and business parks around Sidley, Elva Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can you seal penetrations in a hotel in Sidley after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
What will the job cost?
There isn’t a price list, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Ask the designer to confirm details early on refits
- Include service cupboards in routine inspections
- Get seals inspected before ceilings and boxing close
- Don’t let anyone top up a fire seal with the wrong product
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Fire stopping around Sidley: what changes locally
Approved Document B is the English guidance that covers fire stopping around 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. At about 51 miles from central London, Sidley is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Workshops and IT rooms at colleges like Bexhill 6th Form College, 1.3 miles to the south-east of Sidley, are re-serviced often, leaving penetrations to seal. For a building such as Church of All Saints, new heating or data runs are the usual reason penetrations need sealing.
Sidley is about 1 mile north of Bexhill-on-Sea, in East Sussex. We send applicators to Sidley for service penetrations, handled exactly as we handle every other area. 308 places across East Sussex fall within our area, Sidley among them. Sites around Brighton have their own page, about 26 miles away.

Do you need fire stopping in Sidley?
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Typical triggers for a call:
- Seals that don’t match their tested detail
- Damaged fire seals in risers and voids
- Fire-rated sealant that has cracked or shrunk back
- Openings left by services added after handover
Wherever services are added at a hospital such as Bexhill Hospital, 0.7 miles south of Sidley, the compartment line has to be made good with the specified product.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.
What we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Pipe penetrations
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. For buildings in places like Sidley, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
