Mastic sealing across Rushenden

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Leave it or put it right?

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. Converted and older buildings near places like Rushenden tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Joints cleaned back to sound surfaces
  • CSCS-carded applicators
  • Workmanship guaranteed for 12 months
  • Public liability insurance in place

Mastic sealing in Rushenden

In buildings from before 2000, some old mastics contain 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. We don’t remove asbestos-containing materials. We work on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints, and the failures we’re asked to look at most are leaks at window and door perimeters and failed external movement joints. Whoever orders the work in Rushenden, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Owners and agents with buildings around smaller places such as Rushenden tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Rushenden can be grouped with others nearby. You’ll have a fixed quote before work starts.

  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. 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.

What we need from you

  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need
  • Agree which areas must stay open

Different surfaces, different methods

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Looking after buildings in and around Rushenden

Rushenden lies within about 1 mile of the sea. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, so it’s worth inspecting those sides more often. Rushenden is about 36 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Property owners at sites such as Neats Court Retail Park (to the east of Rushenden) can have mastic renewed between lettings. If your remit includes a building such as Queenborough School and Nursery, frame and door mastic can be programmed for the holidays.

Rushenden is about 2 miles south-west of Sheerness, in Kent. Businesses, contractors and managing agents in Rushenden can call on us for mastic joints. Our Kent coverage takes in 931 places. There’s a separate page for London, about 36 miles away.

We take on mastic joints across the ME11 postcode area, for business premises of every kind. For a building on Well Road, Manor Road and First Avenue or nearby, we can quote for mastic joints. If your building is just outside Rushenden, we cover Queenborough (1 mile north-east), Halfway Houses (2 miles north-east), Sheerness (2 miles north-east), Blue Town (2 miles north) and Grain (3 miles north). Further afield, our area takes in Maidstone (14 miles south-west), Sittingbourne (5 miles south), Whitstable (13 miles east), Faversham (9 miles south-east), Minster (3 miles east) and Davington (9 miles south-east).

When to call us in Rushenden

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Things that usually lead to an enquiry:

  • Movement joints with sealant missing
  • Water getting in round frames after rain
  • Mastic failing across several blocks on an estate
  • Patchy repairs in mismatched sealant

If you look after a block within reach of Queenborough station, 0.6 miles to the north-east of Rushenden, frame and balcony mastic can be renewed on one programme.

How to choose a sealant contractor

Questions about Rushenden

Is Rushenden too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Our building in Rushenden is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How do we ask for a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email us. Include photographs or drawings if you have them.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

What sets the cost

What shapes the price:

  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Backing rod, priming and other preparation

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The postcode of the building
  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email the details over.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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 typically costs more in the end than doing them right.
