About our mastic sealing in Chignall St James
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. If you’re dealing with brittle perimeter mastic across a building and leaks at window and door perimeters, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chignall St James is the same: the right product in a properly prepared joint.
For owners with a single building near Chignall St James, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Common problems we fix in Chignall St James
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Most enquiries start with something like this:
- The same joint failures repeated across a portfolio
- Water getting in round frames after rain
- Damaged joints in communal entrances and corridors
- Patchy repairs in mismatched sealant
If your remit includes a building such as Newlands Spring Primary School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Will failed sealant be removed rather than covered?
- Proof of insurance
- Which product they’ll use, and why it suits the joint
- The terms of the workmanship guarantee
Should maintenance staff do it?
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 normally costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What happens if it’s left?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. Converted and older buildings near places like Chignall St James tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Questions about Chignall St James

Do you cover business parks and estates near Chignall St James, such as Rivermead Industrial Estate?
Yes. Our area takes in Chignall St James and its surroundings, with estates and business parks such as Rivermead Industrial Estate included. A few photographs and the unit address let us price the work.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
