Mastic sealing for Langley sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Prioritise elevations facing the weather
- Group repairs into a planned programme
- Have the asbestos survey to hand for older buildings
- Reduce knocks to communal area joints
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
How we handle mastic sealing in Langley
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. 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. If you are dealing with communal area joints that look neglected and draughts at frames across a block, we can help. A single leaking joint is often how a building in Langley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For buildings around smaller places like Langley, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Langley: questions and answers
We manage a building near Bearsted station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Langley off your patch?
Not at all. Langley is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work for managing agents and housing associations?
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.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long do sealant joints last?
There isn’t a single answer, 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 do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you need mastic sealing in Langley?
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
Clients typically get in touch after noticing one or more of the following:
- Draughts at frames across a block
- Movement joints with sealant missing
- Worn sealant at communal door frames
- Damp patches beside frames
Site managers at schools like Langley Park Primary Academy can fit frame mastic into the summer works.
What to look for in a quote
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area
- The terms of the workmanship guarantee
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Removal of failed or old sealant
- How accessible the joints are
- The product specified
- The size and state of each joint
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.
Sending details for a quote
However big the job, the same details help:
- Specification clauses that apply
- Where the site is, with the postcode
- Your programme or deadline
- Anything awkward about access or site hours
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Mastic sealing around Langley: how the place shapes the job
Two care or nursing homes sit less than 2 miles from Langley. Owners of care premises can bring window and door mastic into a phased programme planned around the home. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.
Property owners at sites such as Park Wood Trading Estate (to the west of Langley) can have mastic renewed between lettings. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.

- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
