About our mastic sealing in Harrowcross
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Site teams most often ask us about movement joints with sealant missing and worn sealant at communal door frames, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. Facilities teams, main contractors and managing agents in Harrowcross tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Harrowcross, we group work so one trip covers it. Photos of each elevation help us quote accurately.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Do you need mastic sealing in Harrowcross?
The edges of the material itself sometimes break away for instance where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.
Clients normally get in touch after noticing something like this:
- Damaged joints in communal entrances and corridors
- Repeated reactive repairs to the same buildings
- Estate-wide sealant that is simply worn out
- Cracked, hardened mastic round windows on a block
If your remit includes a building such as Hedingham School and Sixth Form, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- What level of public liability insurance do they hold?
- How long is the guarantee, and what does it include?
- Their approach to joint depth and backing
- How the joint faces will be prepared and primed
Harrowcross: questions and answers
Is Harrowcross off your patch?
Not at all. Harrowcross is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Do you take on block-wide or estate-wide mastic work in Harrowcross?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For a building around Harrowcross, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We inspect the joints, building by building, and record what has failed and why.
- 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 as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site

Work for main contractors and building owners

What sets the cost
Before we quote, we look at:
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- How much there is to seal
- Access and working height
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- The postcode of the building
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
- Any specification or named product
For a fixed quote, call the office on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
Maintenance after handover
After handover, these steps help:
- Share the asbestos register when you send details
- Log resealing dates block by block
- Check sealant joints during planned building inspections
- Prioritise elevations facing the weather
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Frames, entrances and external joints in Harrowcross
Harrowcross is about 44 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first.
Older community buildings, Church of St Peter among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Rippers Court Industrial Estate, 0.9 miles north-east of Harrowcross, can bring frame, door and external mastic across several units into one programme.
Harrowcross is about 3 miles north-west of Halstead, in Essex. We cover commercial sites throughout Harrowcross, whether it’s a single job or part of a planned programme. Our Essex coverage takes in 644 places, large and small. We also cover London, some 44 miles away.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
