How we handle mastic sealing in Great Hallingbury
Treatment starts with a proper look: 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, with backing rod setting the depth where it’s needed. We work on communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks, and what we are called in for most is brittle perimeter mastic across a building and failed external movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Great Hallingbury it comes down to the same thing: the right product in a properly prepared joint.
For owners with a single building near Great Hallingbury, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. For buildings around smaller places like Great Hallingbury, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Prioritise elevations facing the weather
- Keep bins and bikes away from communal door frames
- Log resealing dates block by block
- Have the asbestos survey to hand for older buildings
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

Your questions answered
Is Great Hallingbury too far out for you?
No. Places such as Great Hallingbury are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you cover business parks and estates near Great Hallingbury, such as The Links Business Centre?
Yes, sites like The Links Business Centre are within our area, along with the rest of Great Hallingbury. A few photographs and the unit address let us price the work.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you send RAMS and CSCS details before starting?
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 hold CHAS accreditation and Constructionline membership.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you reseal a whole block or estate?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
