Mastic sealing in Gordon Hill, done properly
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Most enquiries involve movement joints with sealant missing and the same joint failures repeated across a portfolio, on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints. One point of contact handles commercial sealant work in Gordon Hill from the first photos to the final walk-round, whether it’s one building or several.
Across Greater London, Gordon Hill included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.

Gordon Hill: questions and answers
Will you work in a care home in Gordon Hill without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Will you take on a block within reach of Gordon Hill station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Gordon Hill in your area?
Yes. Gordon Hill is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or email drawings and photos.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

Block-wide mastic in Gordon Hill
London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. Our programme follows the access you agree with residents. The 2 miles around Gordon Hill include four care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Schools and community buildings such as St Michael's CofE Primary School need frame and external mastic kept sound like any building. With historic buildings such as Forty Hall (to the north-east of Gordon Hill) in the wider area, owners of older properties around Gordon Hill should expect mastic to need a product that suits old masonry.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Leaks from above rather than through a joint
- Leaks through the frame itself rather than the perimeter
- Masonry that has broken away beside the joint
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Where we work in Gordon Hill
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Balcony and threshold joints
Different surfaces, different methods
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Why act early in Gordon Hill
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. Getting scaffold, permits or access booked in Gordon Hill takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Building owners, agents and FMs in Gordon Hill
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
What we need from you
- Move anything stored against the joints
- Send any specification or drawings in advance
- Let building users know which areas are affected

Related advice
Do you need mastic sealing in Gordon Hill?
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Common reasons buildings call us in:
- Damaged joints in communal entrances and corridors
- Estate-wide sealant that is simply worn out
- Leaks at window and door perimeters
- Draughts at frames across a block
Trustees of buildings like St Michael & All Angels can bring frame and external mastic into a planned maintenance list.
