Different surfaces, different methods
Communal areas
Communal areas stay in use while we work. Work is planned in sections.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Common questions from High Brooms clients
Is High Brooms off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on a block within reach of High Brooms station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you seal joints high up on a block?
It depends on the building. We agree access with you at quote stage so there are no surprises.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you need mastic sealing in High Brooms?
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.
Clients typically get in touch after noticing one or more of the following:
- Cracked, hardened mastic round windows on a block
- Water getting in round frames after rain
- Patchy repairs in mismatched sealant
- Draughts at frames across a block
Churches, halls and community buildings such as St Matthew's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- What level of public liability insurance do they hold?
- The terms of the workmanship guarantee
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around High Brooms need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Preparing the site
- Point out any areas we must not close
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work

What else we do in High Brooms
Keeping the joints sound
After handover, these steps help:
- Track which buildings were done and when
- Plan resealing building by building rather than complaint by complaint
- Make mastic part of routine maintenance checks
- Check the asbestos register before any old mastic is disturbed
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
