Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Make it easy for occupiers to report draughts
- Log resealing dates block by block
- Share your contractor requirements early
- Make mastic part of routine maintenance checks
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Mastic sealing in Gallows Corner, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. The enquiries we see most involve failed external movement joints and water getting in round frames after rain, across communal kitchens and washrooms, balcony and threshold joints and window and door perimeters on blocks. A single leaking joint is often how a building in Gallows Corner first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In a London area such as Gallows Corner, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Frames, entrances and external joints in Gallows Corner
In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We fit the programme to your notice periods.
Blocks of flats and mixed-use buildings often cluster around stations such as Gidea Park station, 0.8 miles to the south-west of Gallows Corner, and their window and balcony mastic tends to age at the same rate across a building. If your remit includes a building such as Royal Liberty School, frame and door mastic can be programmed for the holidays.
Gallows Corner is about 2 miles north-east of Romford, in Greater London. Across the RM3 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Common questions from Gallows Corner clients
Does your area include sites such as Rom Valley Retail Park, near Gallows Corner?
Yes, sites like Rom Valley Retail Park are within our area, along with the rest of Gallows Corner. Photos and a short description are enough for a first look.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
How long does a job like this take?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When to call us in Gallows Corner
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
What tends to prompt an enquiry:
- Open joints in brickwork or panels
- Old repairs sealed over failed mastic
- Damp patches beside frames
- Occupiers reporting cold air round windows
If you’re responsible for a building such as St Michael and All Angels Church, frame and door mastic needs the same attention as any other property.
What your quote should include
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?
- Who will actually carry out the work
- Can the work be phased to keep areas open?
Building owners, agents and FMs in Gallows Corner
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.

What we need from you

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or send photos by email.

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
