Fire rated sealant for homes and businesses in Aldwych
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. We work on pipe & cable gaps, plasterboard & masonry and door frames, and the jobs we see most are sealant items on a fire risk assessment action list and open joints along the top of partitions.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Aldwych.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. In Aldwych, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Move anything stored near the joints

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- How much there is to do
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.
Signs you need fire rated sealant in Aldwych
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Keep an eye out for any of the following:
- Open holes round services passing through fire walls
- Open joints along the top of partitions
- Joints picked up in a fire-stopping survey
- Damaged fire sealant left by other trades
For buildings such as St Mary le Strand, gaps around pipes and cables are worth checking after any building work there.

What we cannot put right
It helps to know what we cannot do:
- A wall that isn’t a fire-resisting element to begin with
- Sign-off of the building, which sits with building control or your assessor
- Fire doors that need new seals, closers or hardware
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

Why it’s worth doing now in Aldwych
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Rated 4.9 stars on Google
- ARBOMaster approved applicator
- We never seal over old sealant
- Quality sealants from Arbo and Everbuild
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Aldwych questions
Is parking a problem for a job in Aldwych?
Parking in Aldwych, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you take on hotel work around Aldwych?
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.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Do you certify the fire stopping?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
