About our construction mastic in Rush Green
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. If you’re dealing with a mastic package split between trades with no clear owner and frame perimeters left unsealed or poorly sealed, we can help. A single leaking joint is often how a building in Rush Green first comes to us: we look at the rest while we are there and tell you what we find.
Around Rush Green, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Frame gaps too wide for sealant, which the installer needs to correct
- Rework caused by others damaging completed areas
- Joint design decisions that belong to the architect or engineer
If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.
Where we work in Rush Green
- Sanitary and kitchen joints
- Floor and skirting junctions
- Window and door perimeters
- Internal decorators’ caulk
- Cladding and panel joints
- Brick and block movement joints
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, 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.
Why it’s worth doing now in Rush Green
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption, and avoids repeated visits. Snagging can be priced as a separate stage. 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.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Sites and facades in and around Rush Green
The ULEZ covers the whole of Greater London, Rush Green included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in. A number of hotels sit less than 2 miles from Rush Green. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New units and refits on sites such as Rom Valley Retail Park (0.6 miles east of Rush Green) need their panel and perimeter joints sealed to the specification. Hotel extensions and refits, at places such as Mawney Hotel, which lies north of Rush Green, normally run between busy periods, so the sealing is squeezed into short windows.

Cost factors for mastic packages

- How much there is to seal
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The asbestos register, for older buildings
- Specification clauses that apply

- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or send details through our quote form with what you know.

What else we do in Rush Green
Common problems we fix in Rush Green
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Site and facilities staff are often the first to spot these:
- Mastic snags holding up handover
- Caulk cracking where joints are moving more than expected
- Window and door perimeters that won’t pass inspection
- Old sealant on a refurbishment that needs stripping before new work
New wings at hospitals like Queens Hospital (under half a mile north-east of Rush Green) bring long runs of window and panel joints to seal.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
- Who will actually carry out the work
- Is the sealant right for the movement and the substrate?
Rush Green: questions and answers
Could you schedule work at a campus like Barking and Dagenham College for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on jobs in Rush Green where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Is the mastic package guaranteed?
The work is guaranteed for 12 months on the workmanship. Protecting sealed areas from following trades helps avoid damage.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
From enquiry to sign-off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. In Rush Green, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- 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.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand
