About our mastic sealing in Chorleywood West
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve draughts at frames across a block and window mastic that has split and shrunk, across balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints. For commercial sealant work in Chorleywood West, you deal with one contact from quote to sign-off, whether it’s one building or several.
In and around smaller places like Chorleywood West, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What we can’t put right
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
- Masonry that has broken away beside the joint
- Glazing that needs replacing
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.
What we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
Quoting for work in Chorleywood West
We price every job individually. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- How accessible the joints are
- The total length or number of joints
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
However big the job, the same details help:
- Your programme or deadline
- Access details, including height
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or send details through our quote form.
