About our mastic sealing in Hassell Street

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Hassell Street carry our 12-month guarantee. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells, and what we’re called in for most is failed external movement joints and repeated reactive repairs to the same buildings. Most enquiries from Hassell Street start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Hassell Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Before we start on site

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints

Advice

Your questions answered

Will you take on a block within reach of Wye station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Can you quote for mastic across several buildings in and around Hassell Street?

Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we’ll give a fixed quote.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

How long does a job like this take?

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

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Why act early in Hassell Street

Sealing over failed mastic looks tidy for a while. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Older rural buildings around Hassell Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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.

Cost factors for mastic joints

To price the job, we consider:

  • Travel to remote or island sites
  • The size and state of each joint
  • Induction, permit and paperwork requirements
  • How much there is to seal

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

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

  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Planned mastic for Hassell Street portfolios

Hassell Street sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. At about 52 miles from central London, Hassell Street is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.

Schools and community buildings such as Wye School need frame and external mastic kept sound like any building. If you look after a block within reach of Wye station (2.7 miles west of Hassell Street), frame and balcony mastic can be renewed on one programme.
