How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts.

Advice
Mastic sealing in Shellow Bowells
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you have draught complaints from residents or tenants and the same joint failures repeated across a portfolio, we can put it right, on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells alike. A specialist sealant contractor works differently from a general builder: in Shellow Bowells, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Shellow Bowells tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Your questions answered
What paperwork can you provide for a job in Shellow Bowells?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Is a smaller place like Shellow Bowells outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What will the job cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For owners and agents in Shellow Bowells
Central London is about 25 miles from Shellow Bowells. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Shellow Bowells is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you manage student housing near a university such as Writtle University College Cow Watering Campus, 3.2 miles to the east of Shellow Bowells, the summer turnaround is the time for mastic. Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies.

Cost factors for mastic joints
We price every job individually. The things that drive the figure:
- Site requirements such as inductions and permits
- Travel to remote or island sites
- Removal of failed or old sealant
- How much there is to seal
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Access details, including height
- Specification clauses that apply
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Keeping the joints sound
For the best life from the joints:
- Share your contractor requirements early
- Include mastic in your cyclical inspections
- Have the asbestos survey to hand for older buildings
- Group repairs into a planned programme
If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
