Mastic sealing near The Hummicks

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Questions we’re asked in The Hummicks

Is The Hummicks too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Does your area include sites such as Hardley Industrial Estate, near The Hummicks?

Yes. Estates, retail parks and business parks around The Hummicks, Hardley Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Mastic sealing in The Hummicks, done properly

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you are dealing with no planned programme for sealant and a mix of products and colours from past repairs, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in The Hummicks, that means joint design, primers and backing rod as standard.

Around smaller places like The Hummicks, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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

Commercial clients in The Hummicks

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Site requirements such as inductions and permits
  • How much there is to seal
  • Whether old sealant has to be cut out first
  • The product specified

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.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Any specification or named product
  • A wide shot and a close-up of the area
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

To get a fixed quote, ring 01277 525 020 or email drawings and photos. Our quote form is another easy route.

Why it’s worth doing now in The Hummicks

Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around The Hummicks move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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

Why us?

  • Constructionline member for supplier checks
  • Matching to RAL references, product permitting
  • One phone line for London, the South East and Scotland
  • Specification-led, product-correct work

Read our cost guide and how we’re accredited.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Protect low-level joints in entrances
  • Prioritise elevations facing the weather
  • List the paperwork your organisation requires when you send details
  • Avoid piecemeal callouts where you can

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Smaller jobs around The Hummicks can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  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

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Tell staff and tenants when we’ll be in

The Hummicks lies within about 2 miles of the sea. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often.

For owners of several units at places like Hardley Industrial Estate, 2.4 miles north-east of The Hummicks, one programme can deal with frame and external mastic across the lot. If your remit includes a building such as Beaulieu Village Primary School, frame and door mastic can be programmed for the holidays. For agents with blocks near Beaulieu Road station, 4.2 miles north-west of The Hummicks, a block-wide mastic programme deals with frames, balconies and entrances in one go.

When it isn’t the sealant

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

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Broken glass or failed sealed units
  • Masonry that has broken away beside the joint

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly before you book.
