From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Mountnessing may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.

Mastic sealing in Mountnessing, done properly
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. The enquiries we see most involve water getting in round frames after rain and worn sealant at communal door frames, across communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Mountnessing, preparation and product choice get the time they need.
Around smaller places like Mountnessing, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
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.

What we’re called out for in Mountnessing
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

- Leaks at window and door perimeters
- Draughts at frames across a block
- Damaged joints in communal entrances and corridors
- Old repairs sealed over failed mastic
Buildings close to stations like Ingatestone station (1.6 miles north-east of Mountnessing) are often flats over shops, with frame mastic to keep sound.

- Who will actually carry out the work
Site staff or a sealant 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 typically costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
