Looking after buildings in and around Rivenhall End
Rivenhall End is about 39 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Landlords with units on estates such as Gold Key Industrial Estate, 2.2 miles north-east of Rivenhall End, can bring frame, door and external mastic across several units into one programme. Buildings close to stations like Witham station (to the south-west of Rivenhall End) are often flats over shops, with frame mastic to keep sound. Site managers at schools like Rivenhall Church of England Primary School can fit frame mastic into the summer works.

FAQs: Rivenhall End
Will you take on a block within reach of Witham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is Rivenhall End too far out for you?
Not at all: smaller places are covered as well as 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 do block-wide mastic programmes?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
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.
Surface by surface
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Why deal with it now?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Older rural buildings around Rivenhall End move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Plan resealing building by building rather than complaint by complaint
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
What sets the cost
Quotes vary with the job. It mainly depends on:
- How accessible the joints are
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- Travel to remote or island sites
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Access details, including height
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Rivenhall End need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Point out any areas we must not close
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
