For owners and agents in Lilyvale

The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 53 miles from Lilyvale. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

If you look after a block within reach of Westenhanger station, 2.9 miles to the south-east of Lilyvale, frame and balcony mastic can be renewed on one programme. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.

Lilyvale is about 5 miles east of Ashford, in Kent. Businesses, contractors and managing agents in Lilyvale use us for work on mastic joints, as part of our coverage of Kent. Across Kent, 931 places are covered, including Lilyvale. Brighton is covered too, around 52 miles from Lilyvale.

Mastic sealing in Lilyvale, done properly

Owners and agents typically 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. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. Most enquiries involve brittle perimeter mastic across a building and complaints coming in block by block, on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lilyvale it comes down to the same thing: the right product in a properly prepared joint.

For buildings around smaller places like Lilyvale, we group work so one trip covers it. Photos of each elevation help us quote accurately.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

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.

Your questions answered

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

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

Will you take on work at estates like Evegate Business Park, close to Lilyvale?

Yes. Our area takes in Lilyvale and its surroundings, with estates and business parks such as Evegate Business Park included. A few photographs and the unit address let us price the work.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you supply RAMS and insurance details?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Does the weather affect the work?

Outside, 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. Inside work is seldom held up.

Is Lilyvale in your area?

Yes. Lilyvale is in our area and the rest of Kent. To discuss a job, speak to us on 01277 525 020 or email drawings and photos.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.

When to call us in Lilyvale

Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

What tends to prompt an enquiry:

  • Patchy repairs in mismatched sealant
  • Water getting in round frames after rain
  • Worn sealant at communal door frames
  • Draughts at frames across a block

Property owners at sites such as Evegate Business Park, 1.2 miles west of Lilyvale, can have mastic renewed between lettings.

How to choose a sealant contractor

What the job involves on each surface

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Glazing that needs replacing
  • Masonry that has broken away beside the joint
  • Water coming in from the roof or rainwater goods

If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Smaller jobs around Lilyvale can be grouped with others nearby. A fixed quote is given before anything starts.

  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.

After the work

After handover, a little attention goes a long way:

  • Make mastic part of routine maintenance checks
  • Check the asbestos register before any old mastic is disturbed
  • Log resealing dates block by block
  • Reduce knocks to communal area joints

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

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