After the work
For the best life from the joints:
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
- Log resealing dates block by block
- Reduce knocks to communal area joints
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.

Common questions from Boxted Cross clients
Do you work for managing agents with blocks near Colchester station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Boxted Cross off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Mastic sealing in Boxted Cross: the local picture
Rainfall across the South East, Boxted Cross included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Boxted Cross lies roughly 54 miles out 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.
If you own or manage units on a site such as Langham Barns Business Centre (1.1 miles south-east of Boxted Cross), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Older community buildings, Church of St Peter among them, often have frames of mixed ages whose mastic varies.
Boxted Cross is about 5 miles north of Colchester, in Essex. Commercial clients in Boxted Cross use us for work on mastic joints. Our Essex coverage takes in 644 places, large and small. For work in that direction, see our London page.

How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area.

- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.

Advice
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Substrate edges that need repairing first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Failed window or door frames, which need a window contractor
If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
What we’re called out for in Boxted Cross
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Typical triggers for a call:
- A mix of products and colours from past repairs
- Complaints coming in block by block
- Occupiers reporting cold air round windows
- Failed external movement joints
With historic buildings such as Castle House (to the east of Boxted Cross) in the wider area, owners of older properties around Boxted Cross should expect mastic to need a product that suits old masonry.
What your quote should include
- What level of public liability insurance do they hold?
- Health and safety accreditation such as CHAS
- How they handle RAMS and site documents
- How joint depth will be controlled
Different surfaces, different methods
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We will confirm the colours available for the specified product.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
