Common problems we fix in Hare Street
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
These are the problems we are asked about most:
- Fire seals that have cracked with movement
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
- Seals cut through by electricians, plumbers or data installers
Community buildings like Church of St Margaret of Antioch are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- What insurance they hold
- How hidden problems are handled
- Whether the sealant suits the joint
- Whether VAT is included
About our fire rated sealant in Hare Street
We often work from an action list drawn up by a fire risk assessor on buildings across Hare Street. Send us the list or the survey and we will quote for the fire-rated sealant work on it. Typical jobs include gaps around pipes and cables through fire-resisting walls and open gaps behind door architraves, across pipe & cable gaps, linear gaps and plasterboard & masonry.
If you have holiday lets, a converted barn used for business or a community building near Hare Street, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Your questions about fire rated sealant in Hare Street
Is Hare Street within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on fire rated sealant in Hare Street?
All our work, in Hare Street and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you take on fire stopping in schools and offices?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.

Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Hare Street and the rest of Essex, along with the rest of our area.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door leaf and its hardware need a door specialist.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Hare Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
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.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

Why it’s worth doing now in Hare Street
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again when the building is next checked. Where a wall is exposed, as many are in small places like Hare Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each and we flag any that need another system.
