About our fire rated sealant in Dorchester
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. Common call-outs are for open holes round services passing through fire walls and sealant items on a fire risk assessment action list, on linear gaps, pipe & cable gaps and flats & HMOs.
If you have holiday lets, a converted barn used for business or a community building near Dorchester, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Whatever the size of the job, you get the same 12-month guarantee in Dorchester and across Oxfordshire.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Fire rated sealant in Dorchester: local notes
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Dorchester. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Managing a site like Dorchester St Birinus Church of England School? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Dorchester Abbey are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. In a small place like Dorchester, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Do you need fire rated sealant in Dorchester?
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Most people get in touch after spotting one of these:
- Standard silicone or caulk in a fire-stopping gap
- Open joints along the top of partitions
- Fire seals that have cracked with movement
- Gaps around pipes and cables through fire-resisting walls
For landlords with property near Culham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for Dorchester
Can you help a landlord with a rental near Culham station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you take on hotel work around Dorchester?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we can quote for the fire-rated sealant items.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What information do you need?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you cover Dorchester?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Dorchester.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Dorchester, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Different surfaces, different methods
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the sealant bonds.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Tell trades working in the building that fire seals must be put back
- Take pictures of fire stopping before ceilings or boxing go back
- Never patch a fire seal with standard sealant
- File the fire-stopping record where your assessor can find it
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
