Mastic sealing in Upminster Bridge
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle mastic sealing in Upminster Bridge
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are movement joints with sealant missing and brittle perimeter mastic across a building. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Upminster Bridge, that means joint design, primers and backing rod as standard.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost
What shapes the price:
- Whether old sealant has to be cut out first
- Travel to remote or island sites
- The site’s rules and procedures
- The size and state of each joint
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Sending details for a quote
However big the job, these details speed things up:
- What the building is and how it’s used
- Access details, including height
- Any dates the work must fit around
- Any specification or named product
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from a day to a few weeks, depending on the number of buildings and joints. All of Greater London is in the ULEZ, and kerbside space in Upminster Bridge can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- 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.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
- Confirm the product named in the specification

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions about Upminster Bridge
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Do you work for managing agents with blocks near Upminster station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Do you work in Upminster Bridge?
Yes. We cover Upminster Bridge, and you can call 01277 525 020 or send details through our quote form to get started.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When it isn’t the sealant
A few problems need another trade or a different fix, 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
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

When to call us in Upminster Bridge
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
What tends to prompt an enquiry:
- Estate-wide sealant that is simply worn out
- No planned programme for sealant
- Leaks at window and door perimeters
- Open joints in brickwork or panels
If your remit includes a building such as Sacred Heart of Mary Girls' School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- Their public liability cover
- How they handle RAMS and site documents
