Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Ask which product is in place before decorating
- Ask the designer to confirm details early on refits
- Put resealing into every M&E and fit-out package
- Keep product data and details in the fire safety file
Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
About our fire stopping in Swanmore
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have builders’ foam or ordinary silicone in compartment walls and old intumescent sealant that has split away, we can help, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads alike. Searching for sealant specialists in Swanmore? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Converted and extended buildings around places like Swanmore can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Penetration seals near Swanmore
A number of hotels sit less than 2 miles from Swanmore. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Hospital estates such as Knowle Hospital, 4.3 miles to the south of Swanmore, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a school such as Swanmore Church of England Aided Primary School, penetration sealing fits best at the end of the summer works. Halls and meeting rooms at places like Church of St Barnabas sometimes gain new services, and any compartment wall crossed needs the specified seal.

Questions about Swanmore
Is Waltham Business Park, near Swanmore, within your area?
Yes. Estates, retail parks and business parks around Swanmore, Waltham Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is Swanmore too far out for you?
No. Places such as Swanmore are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Will you write the fire-stopping specification?
No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.
How do you choose the sealant?
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.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Work in places the size of Swanmore is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
- Tell us which areas need to stay in use
Ask for a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email the details over.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Walls or floors that aren’t fire-resisting to begin with
- Plastic pipes whose detail calls for a collar or wrap
- Fire risk assessments, a job for a competent assessor
If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How the job changes by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.
Owners, agents and contractors
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.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
