How we handle facade sealing in Rush Green

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve old perimeter mastic that has dried out and staining on stone next to old sealant, across coping and flashing joints, shopfront frames and stone and brick facade joints. A single leaking joint is often how a building in Rush Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Facade sealing around Rush Green: how the place shapes the job

Rush Green has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Rush Green. Delivery slots and scarce storage shape how and when the mastic goes in.

Recladding or extending a unit at a site like Rom Valley Retail Park, 0.6 miles east of Rush Green, brings panel joints and frame perimeters into the programme. School extensions, at buildings such as Rush Green Primary School, typically run to the summer holidays, mastic included. Further education sites such as Barking and Dagenham College (less than half a mile south of Rush Green) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Rush Green is about 1 mile south-west of Romford, in Greater London. Across the RM7 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Leave it or put it right?

Topping up a failed joint typically buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What you get with us

  • Work to your specification and the manufacturer’s guidance
  • Failed material removed, not covered up
  • Fully insured
  • Colours chosen to suit frames, cladding or finishes where possible

Read our cost guide and our accreditations.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Backing rod, priming and other preparation
  • The site’s rules and procedures
  • Location, for remote and island sites
  • The total length or number of joints

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.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • The product your specification calls for
  • Clear photographs of the problem areas
  • When you need the work done
  • The site address and postcode

Send us photographs, 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.

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Surface by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, as the specification sets out.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Don’t wait for a second leak before calling
  • Plan facade sealing alongside redecoration
  • Insist on a full cut-out when joints are renewed
  • Walk the elevations once or twice a year

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

Questions we are asked in Rush Green

Can work at a site such as Barking and Dagenham College fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is hospital work, at somewhere like Queens Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do you seal facades in winter?

Rain and frost can pause external sealing. We plan for weather and keep you updated.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Rush Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
