Fire rated sealant in Shacklewell
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have unsealed gaps around fire door frames and gaps flagged on a fire risk assessment, we can help, on pipe & cable gaps, door frames and service penetrations alike.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Shacklewell, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Each job carries a 12-month guarantee, whatever its size.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Store the list of sealed gaps with your building paperwork
- Report cracked or damaged seals as soon as you notice them
- Ask every contractor to reseal any fire stopping they disturb
- Allow for resealing whenever new services are run
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.

Commercial buildings in Shacklewell
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
As a London address, Shacklewell can be tricky for parking: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as Church of St Barnabas, gaps around pipes and cables are worth checking after any building work there. If you let a flat or house near Rectory Road station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of gaps, and longer for a whole building, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Landlord and commercial work in Shacklewell
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why deal with it now?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
