Mastic sealing for East Langdon sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How the quote is worked out

Before we quote, we look at:

  • Location, for remote and island sites
  • How accessible the joints are
  • The total length or number of joints
  • The size and state of each joint

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Any specification or named product

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email us to discuss it first.

Mastic sealing in East Langdon

Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Site teams most often ask us about failed external movement joints and window mastic that has split and shrunk, on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in East Langdon 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 East Langdon, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Frames that are rotten, warped or broken
  • Masonry that has broken away beside the joint
  • Asbestos-containing sealant, which we don’t remove

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

Surfaces we seal

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

What the job involves on each surface

Planned maintenance

We can work into your cyclical maintenance plan on a timetable you set.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

Looking after buildings in and around East Langdon

With the shore within about 3 miles, East Langdon counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Central London is about 66 miles from East Langdon. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

For a school such as Langdon Primary School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like White Cliffs Business Park, 1.7 miles south-west of East Langdon, one programme can deal with frame and external mastic across the lot. If you are responsible for a building such as Church of St Augustine, frame and door mastic needs the same attention as any other property.

East Langdon is about 3 miles north-east of Dover, in Kent. We cover East Langdon, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, East Langdon among them. London is covered too, some 66 miles away.

Why act early in East Langdon

Failed perimeter mastic lets cold air in around frames and the windows typically get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Around East Langdon, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Keep bins and bikes away from communal door frames
  • Avoid piecemeal callouts where you can
  • Encourage occupiers to report problems at frames
  • Share your contractor requirements early

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.

Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.

Your questions answered

Can you work at a site such as White Cliffs Business Park, by East Langdon?

Yes. We cover East Langdon and the area around it, including industrial estates, business parks and retail parks such as White Cliffs Business Park. Send details of the unit and the work through our quote form for a quick quote.

Does the sea air around East Langdon change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do you work with property factors and landlords?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Is East Langdon in your area?

Yes. Sites across East Langdon are covered, and the same phone number covers every area.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How long do sealant joints 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.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near East Langdon may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
