About our mastic sealing in Swan Street

Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are draught complaints from residents or tenants and damaged joints in communal entrances and corridors. A specialist sealant contractor works differently from a general builder: on jobs in Swan Street, preparation and product choice get the time they need.

For buildings around smaller places like Swan Street, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Distance, for remote addresses

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The postcode of the building
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • The product your specification calls for

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email the details over.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Swan Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Preparing the site

  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions
  • Flag any permit to work we’ll need

Blocks and managed buildings in Swan Street

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Swan Street is about 46 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.

Blocks of flats and mixed-use buildings often cluster around stations such as Chappel & Wakes Colne station (to the north-east of Swan Street) and their window and balcony mastic tends to age at the same rate across a building. Site managers at schools like Chappel Church of England Controlled Primary School can fit frame mastic into the summer works. Property owners at sites such as Earls Colne Business Park, 2.9 miles to the west of Swan Street, can have mastic renewed between lettings.

Swan Street is about 5 miles south-east of Halstead, in Essex. Commercial clients in Swan Street can call on us for mastic joints, as part of our coverage of Essex. We work across 644 places in Essex, from busy centres to rural villages. There’s a separate page for London, about 46 miles away.

Why act early in Swan Street

Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Converted and older buildings near places like Swan Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Why us?

  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over
  • CHAS accredited
  • RAL and finish matching where the product range allows

See how commercial sealant jobs are priced and our accreditations and insurance.

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Glazing that needs replacing
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

  • Shopfronts below residential blocks
  • External wall and movement joints
  • Communal entrances and stairwells
  • Communal kitchens and washrooms
  • Balcony and threshold joints
  • Window and door perimeters on blocks

Owners, agents and contractors

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Redoing a failed joint usually 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.

FAQs: Swan Street

Will you take on a block within reach of Chappel & Wakes Colne station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Will you take on work at estates like Earls Colne Business Park, close to Swan Street?

Yes, sites like Earls Colne Business Park are within our area, along with the rest of Swan Street. A few photos and the unit address let us price the work.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is asbestos a concern with old mastic?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Do you cover Swan Street?

Yes. We cover Swan Street and the rest of Essex, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or send details through our quote form.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
