Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
A fixed quote reflects the actual work. It allows for:
- The size and state of each joint
- How much existing material needs removing
- Site requirements such as inductions and permits
- Working within restricted access windows
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
- Access details, including height
- The postcode of the building
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email the details over.
About our fire stopping in Blendworth
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Blendworth and nearby. Most enquiries involve expanding foam used as fire stopping and openings found when ceilings come down for a refit, on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows. Searching for sealant specialists in Blendworth? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Rural conversions around Blendworth can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

After the work
After handover, these steps help:
- Settle who seals which penetrations at the start of a project
- Look above ceilings when tiles are lifted for other jobs
- Ask which product is in place before decorating
- Keep product data and details in the fire safety file
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.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Do you need fire stopping in Blendworth?
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.
Most enquiries start with something like this:
- Fire-stopping items raised at inspection or handover
- Service penetrations left open after M&E works
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
For a hospital such as Havant War Memorial Hospital (4.3 miles south of Blendworth), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- What site paperwork they can supply
- Their plan for phasing and protecting the area
Your questions answered
Is Blendworth too far out for you?
No. Places such as Blendworth are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you work in occupied care homes around Blendworth?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you work in Scotland as well as England?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Blendworth may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
What we need from you
- Make sure the joints can be reached
- Warn occupants and staff about the work
- Agree which areas must stay open

Advice
Fire stopping in Blendworth: the local picture
Blendworth has two care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Approved Document B is the English guidance that covers fire stopping around 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.
On estates like Westfield Industrial Estate, which lies south-west of Blendworth, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. In a school such as Horndean Church of England Junior School, fire-rated sealant goes in around service penetrations where it is specified.
Blendworth is about 1 mile north-east of Horndean, in Hampshire. If you’re looking for fire stopping in Blendworth, we can help. Across Hampshire, 723 places are covered, Blendworth among them. Sites around Portsmouth have their own page, about 8 miles away.

Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
