About our fire stopping in Dorchester
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve fire seals cut back for extra cables and never reinstated and head-of-wall gaps with no fire seal, on cable penetrations, joints between fire-resisting walls and floors and service gaps in risers. A single leaking joint is often how a building in Dorchester first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Dorchester still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Compartment walls and floors in Dorchester
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Dorchester has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Hospital estates such as Littlemore Hospital (5.6 miles north-west of Dorchester) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a building such as Dorchester Abbey, new heating or data runs are the usual reason penetrations need sealing.

Questions we’re asked in Dorchester
Is Dorchester too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Littlemore Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
How many days will you need on site?
It depends on the scope, but the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For bigger or phased jobs, we will set out a timescale with the quote.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Rural sites near Dorchester may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Arrange parking or a loading space
- Flag any permit to work we’ll need
- Share your working hours and any access restrictions
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Signs you need fire stopping in Dorchester
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.
It’s worth sending us details if you spot any of the following:
- Unsealed penetrations discovered above suspended ceilings
- Openings left by services added after handover
- Penetration schedules that need working through
- Expanding foam used as fire stopping
Schools such as Dorchester St Birinus Church of England School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Proof of insurance
- Their approach to joint depth and backing
- Their plan for phasing and protecting the area
Quoting for work in Dorchester
To price the job, we consider:
- Whether old sealant has to be cut out first
- The product specified
- The total length or number of joints
- How accessible the joints are
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- The product your specification calls for
- Your programme or deadline
- A wide shot and a close-up of the area
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.
Why it’s worth doing now in Dorchester
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Converted and older buildings near places like Dorchester tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

After the work
Keep the joints in good shape with a few simple steps:
- Keep product data and details in the fire safety file
- Check with the data sheet before painting over fire sealant
- Ask the designer to confirm details early on refits
- Look above ceilings when tiles are lifted for other jobs
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.
