Fire Rated Sealant in Wembley
Problem with your fire-stopping gaps in Wembley? We cut out the old, prepare the joints and apply the right sealant.
- Joints picked up in a fire-stopping survey
- Ordinary sealant used where a fire-rated product was needed
- Open gaps behind door architraves
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It usually takes from a few hours to a few days, depending on the number of gaps and the access. In Wembley, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Advice
About our fire rated sealant in Wembley
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you have gaps where walls meet ceilings or slabs and gaps around pipes and cables through fire-resisting walls, we can put it right.
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 Wembley, and room-by-room programmes can be planned where needed.
Every job comes with a one-year guarantee, wherever you are in Greater London.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Commercial buildings in Wembley
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. Wembley has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Schools such as Wembley Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. As a London address, Wembley can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near North Wembley station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

When it isn’t the sealant

- Large holes that need a different fire-stopping system
- Walls or floors that weren’t built to resist fire
- Sign-off of the building, which sits with building control or your assessor

Surface by surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length.

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail, and we will tell you.
How we quote for fire rated sealant
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site
- Whether the work is at height
- The type of sealant required
- How many areas need sealing
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:

How to look after the new joints
After the cure time, these simple habits help:
- Report cracked or damaged seals as soon as you notice them
- Never patch a fire seal with standard sealant
- Allow for resealing whenever new services are run
- Ask which product was used before you paint
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Wembley questions
Do you take on hotel work around Wembley?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can you help a landlord with a rental near North Wembley station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Wembley.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you seal gaps around fire door frames?
Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself, and we will mention anything we notice about the door.
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.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
