Mastic sealing across Malting Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Mastic sealing in Malting Green, done properly

Across Malting Green and the rest of Essex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you’re dealing with the same joint failures repeated across a portfolio and cracked, hardened mastic round windows on a block, we can help, on communal kitchens and washrooms, window and door perimeters on blocks and external wall and movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Malting Green, that means joint design, primers and backing rod as standard.

For owners with a single building near Malting Green, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.

What our 12-month guarantee covers is the way we did the job: 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.

Blocks and managed buildings in Malting Green

Malting Green lies roughly 48 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Malting Green is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

Older community buildings, Church of St Andrew among them, often have frames of mixed ages whose mastic varies. For owners of several units at places like Gosbeck's Business Park, 1.6 miles to the north of Malting Green, one programme can deal with frame and external mastic across the lot.

Malting Green is about 3 miles south of Colchester, in Essex. Commercial clients in Malting Green use us for work on mastic joints, as part of our coverage of Essex. Across Essex, 644 places are covered, Malting Green among them. Our London page has more on work in that area.

Common problems we fix in Malting Green

Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Things that typically lead to an enquiry:

  • Water getting in round frames after rain
  • Complaints coming in block by block
  • Brittle perimeter mastic across a building
  • Movement joints with sealant missing

Site managers at schools like Alderman Blaxill School can fit frame mastic into the summer works.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Malting Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Before we start on site

  • Let us know about inductions and permits
  • Move anything stored against the joints
  • Share the asbestos register for older buildings

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

  • Materials that need asbestos testing before work
  • Broken glass or failed sealed units

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.

What we seal

  • Balcony and threshold joints
  • Communal entrances and stairwells
  • Window and door perimeters on blocks

  • External wall and movement joints
  • Shopfronts below residential blocks

Questions we’re asked in Malting Green

Is Malting Green off your patch?

Not at all. Malting Green is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you cover business parks and estates near Malting Green, such as Gosbeck's Business Park?

Yes. We cover Malting Green and the area around it, including industrial estates, business parks and retail parks such as Gosbeck's Business Park. A few photos and the unit address let us price the work.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

How do you reach windows on upper floors?

Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

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 you can arrange it with occupiers.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Looking after the joints

For the best life from the joints:

  • Make mastic part of routine maintenance checks
  • Have the asbestos survey to hand for older buildings
  • Group repairs into a planned programme
  • Prioritise elevations facing the weather

Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

What affects the price in Malting Green

These are the things that shape the price:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • Specification clauses that apply
  • The asbestos register, for older buildings
  • Access details, including height
  • The site address and postcode

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
