What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
If you’re not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks

- Communal entrances and stairwells
- Window and door perimeters on blocks
Mastic sealing in Orchard Leigh, done properly
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and the failures we are asked to look at most are mastic failing across several blocks on an estate and open joints in brickwork or panels. One point of contact handles commercial sealant work in Orchard Leigh from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For owners with a single building near Orchard Leigh, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Orchard Leigh
Do you work for managing agents with blocks near Berkhamsted station?
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 a smaller place like Orchard Leigh outside your area?
Not at all. Orchard Leigh is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
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 we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Orchard Leigh can form part of a wider programme.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Orchard Leigh. Several sites can go on one quote, which keeps the paperwork simple.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
How the job changes by surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Mastic sealing in Orchard Leigh: the local picture
Central London is about 26 miles from Orchard Leigh. Managed blocks of flats are a big part of commuter-belt property. Orchard Leigh is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
If you look after a block within reach of Berkhamsted station (3 miles north of Orchard Leigh), frame and balcony mastic can be renewed on one programme. Older community buildings, St George's Church among them, often have frames of mixed ages whose mastic varies.

Common problems we fix in Orchard Leigh
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Typical triggers for a call:
- The same joint failures repeated across a portfolio
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
- Damp patches beside frames
Student blocks close to universities like Buckinghamshire New University (to the south-west of Orchard Leigh) are easiest to work on between tenancies.
Questions to ask before you book
- Who will actually carry out the work
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
