Mastic sealing for commercial buildings in Brockhill
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Site teams most often ask us about mastic failing across several blocks on an estate and occupiers reporting cold air round windows, across external wall and movement joints, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Brockhill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Brockhill tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Brockhill
We manage a building near Martins Heron station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Brockhill off your patch?
Not at all. Brockhill is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Will residents or tenants be disturbed?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Why act early in Brockhill
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Around Brockhill, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Surface by surface
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Blocks and managed buildings in Brockhill
Brockhill is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Central London is about 27 miles from Brockhill. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
Student blocks close to universities like Imperial College Silwood Park Campus (3.6 miles south-east of Brockhill) are easiest to work on between tenancies. If you are responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

When to call us in Brockhill
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Common reasons buildings call us in:
- Leaks at window and door perimeters
- Complaints coming in block by block
- Old repairs sealed over failed mastic
- Open joints in brickwork or panels
Older buildings near Brockhill, from historic houses such as St Leonard's Hill (3.4 miles north-east of Brockhill) to more modest stock, need compatible products when frames are resealed.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Have the asbestos survey to hand for older buildings
- Ask residents or tenants to report leaks and draughts early
- Avoid piecemeal callouts where you can
- Log resealing dates block by block
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
