Mastic sealing in Seven Kings, done properly
For blocks and buildings in Seven Kings and across Greater London, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. If you are dealing with patchy repairs in mismatched sealant and movement joints with sealant missing, we can put it right.

London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Surface by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.
Why deal with it now?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What you get with us
- One contact handling all your sites
- Work to your specification and the manufacturer’s guidance
- Health and safety: CHAS accredited
- Constructionline member for supplier checks

When to call us in Seven Kings
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
Clients normally get in touch after noticing one or more of the following:
- Draughts at frames across a block
- Complaints coming in block by block
- A mix of products and colours from past repairs
- The same joint failures repeated across a portfolio
Schools and community buildings such as Downshall Primary School need frame and external mastic kept sound like any building.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
What affects the price in Seven Kings
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Phasing around occupants
- How accessible the joints are
- Location, for remote and island sites
- Induction, permit and paperwork requirements
Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them
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, photographs and a description will do.

From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Send any specification or drawings in advance
- Agree which areas must stay open
- Flag any permit to work we’ll need
Ask for a quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
Your questions answered
Do you work for managing agents with blocks near Seven Kings station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you work at a site such as Newbury Retail Park, by Seven Kings?
Yes, sites like Newbury Retail Park are within our area, along with the rest of Seven Kings. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
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.
How do you handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
Maintenance after handover
For the best life from the joints:
- Include mastic in your cyclical inspections
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Keep a record of when each building was resealed
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
