About our fire stopping in Gallows Corner
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. Most enquiries involve head-of-wall gaps with no fire seal and fire stopping installed outside its tested range, on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors. Searching for sealant specialists in Gallows Corner? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you’ll hear it from us.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Gallows Corner: questions and answers
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Is hospital work, at somewhere like Victoria Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Do you have third-party installer accreditation for fire stopping?
No, and we won’t imply otherwise. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so check your contract first. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you work in Gallows Corner?
Yes. Gallows Corner is in our area. For a quote, ring 01277 525 020 or send photos by email.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Signing off or certifying a building’s fire stopping
- Writing the fire-stopping specification
- Construction that lacks the fire resistance the seal relies on
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Commercial clients in Gallows Corner
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Gallows Corner can form part of a wider programme.
When to call us in Gallows Corner
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
- Head-of-wall gaps with no fire seal
- Fire sealant pulled out of the opening
In a hotel such as Park Hotel Essex (0.6 miles south-west of Gallows Corner), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- What the guarantee covers, and for how long
- Their pre-qualification and accreditations
- How joint depth will be controlled
Service penetrations in Gallows Corner buildings
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. A 2-mile radius around Gallows Corner takes in a number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.
In a retail centre such as The Mercury Mall, 1.5 miles to the south-west of Gallows Corner, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Wherever services are added at a hospital such as Victoria Hospital (to the south-west of Gallows Corner) the compartment line has to be made good with the specified product.

Should maintenance staff do it?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.
Small ducts
We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Warn occupants and staff about the work
- Send your site hours and access windows
- Make sure the joints can be reached
