From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once.

Give us the hours we can be on site and we will schedule to suit.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Clear stock, furniture or equipment away from the joints

Construction mastic in Redbridge
We work to the specification and the programme. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out. Site teams most often ask us about failed sealant in an existing building being refurbished and new external sealant already peeling away, across internal decorators’ caulk, sanitary and kitchen joints and brick and block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Redbridge it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

Quoting for work in Redbridge
Before we quote, we look at:
- Joint width, depth and condition
- Distance, for remote addresses
- How much existing material needs removing
- How much there is to seal
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
To price the job accurately, we need to understand the site. Send us:
- Where the site is, with the postcode
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or use the quote form.
After the work
To get the most from the new sealant:
- Plan external elevations with the weather in mind
- Get the mastic subcontractor involved early in the programme
- Keep finished joints away from paint, plaster and scrapers
- Ask cleaners to use soft cloths around fresh sealant
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover, priced as part of the package or separately.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Questions we’re asked in Redbridge
Can you work around term dates at a campus such as New City College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you cover Redbridge?
Yes. Redbridge is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or email a schedule or drawings.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Site staff or a sealant specialist?
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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
What we’re called out for in Redbridge
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
It’s worth sending us details if you spot any of the following:
- Sealant knocked or painted over by other trades
- A long mastic snag list close to completion
- New external sealant already peeling away
- Cracks opening in caulked internal joints
Extensions at sites like King George Hospital (2.3 miles south-west of Redbridge) normally sit beside working departments, and the mastic follows strict access rules.
What to look for in a quote
- Will RAMS and insurance details be available?
- How the existing material will be dealt with
- The named product and why it was chosen
- Their approach to joint depth and backing
Leave it or put it right?
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. Where an alternative is genuinely suitable, we will say so. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Pricing mastic packages depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.
