Mastic sealing in Hawkenbury

Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. Most enquiries involve draughts at frames across a block and estate-wide sealant that is simply worn out, on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. Facilities teams, main contractors and managing agents in Hawkenbury tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For owners with a single building near Hawkenbury, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Hawkenbury are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed

Advice

Common questions from Hawkenbury clients

Can you work at a site such as Barradale Farm Industrial Estate, by Hawkenbury?

Yes. Our area takes in Hawkenbury and its surroundings, with estates and business parks such as Barradale Farm Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Is Hawkenbury too far out for you?

Not at all. Hawkenbury is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you reach windows on upper floors?

Every block is different. We agree access with you at quote stage so there are no surprises.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

How the job changes by surface

Tenement and older buildings

Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.

External movement joints

Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Broken glass or failed sealed units
  • Leaks through the frame itself rather than the perimeter
  • Materials that need asbestos testing before work

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.

Where we work in Hawkenbury

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

Block-wide mastic in Hawkenbury

Hawkenbury is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first. At about 37 miles from central London, Hawkenbury is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.

For agents with blocks near Staplehurst station, which lies west of Hawkenbury, a block-wide mastic programme deals with frames, balconies and entrances in one go. Landlords with units on estates such as Barradale Farm Industrial Estate (to the east of Hawkenbury) can bring frame, door and external mastic across several units into one programme.

Why it’s worth doing now in Hawkenbury

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Hawkenbury. Photos of every joint help us quote for the whole job.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

What affects the price in Hawkenbury

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Removal of failed or old sealant

A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • How the joints are reached, and at what height
  • The postcode of the building
  • Your programme or deadline
  • The asbestos register, for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

When to bring in a specialist

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.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
