Mastic sealing across Edenbridge

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Materials that need asbestos testing before work
  • Frames that are rotten, warped or broken
  • Misted or failed double-glazed units

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

About our mastic sealing in Edenbridge

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. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is damp patches beside frames and old repairs sealed over failed mastic. Most enquiries from Edenbridge start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Places the size of Edenbridge normally have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Our process

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. For a site in Edenbridge, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Preparing the site

  • Flag any permit to work we will need
  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.

Advice

Looking after the joints

After handover, these steps help:

  • Check the asbestos register before any old mastic is disturbed
  • Look at the sunniest and most exposed elevations first
  • Make it easy for occupiers to report draughts
  • Reduce knocks to communal area joints

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.

Planned mastic for Edenbridge portfolios

Edenbridge sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. At about 22 miles from central London, Edenbridge is within reach of the capital. 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.

For agents with blocks near Edenbridge Town station, less than half a mile to the east of Edenbridge, a block-wide mastic programme deals with frames, balconies and entrances in one go. With historic buildings such as Hever Castle (to the south-east of Edenbridge) in the wider area, owners of older properties around Edenbridge should expect mastic to need a product that suits old masonry.

Edenbridge is about 6 miles north-east of East Grinstead, in Kent. Edenbridge sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Edenbridge is one of 931 places we cover in Kent for mastic joints. For work in that direction, see our London page.

Work on mastic joints is covered throughout TN8, whatever the building. Streets here include Station Road, High Street and Wellingtonia Way. Edenbridge sits on or close to the B2026 and B2027. Close to Edenbridge, our area also takes in Marlpit Hill (1 mile north), Mowshurst (1 mile north-east), Troy Town (1 mile north-west), Pootings (2 miles north-east) and Four Elms (2 miles north-east). A short drive away, we cover Sevenoaks (8 miles north-east), Royal Tunbridge Wells (10 miles south-east), Tonbridge (9 miles east), Swanley (14 miles north), Paddock Wood (14 miles east) and Southborough (9 miles east).

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Edenbridge. Several sites can go on one quote, which keeps the paperwork simple.

How the job changes by surface

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.

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.

Edenbridge: questions and answers

Is Edenbridge off your patch?

Not at all. Edenbridge is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can one quote cover a number of our buildings near Edenbridge?

Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.

Can you send RAMS and CSCS details before starting?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

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.

Can weather delay the job?

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

Do you need mastic sealing in Edenbridge?

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.

Look out for the following:

  • Damp patches beside frames
  • Draught complaints from residents or tenants
  • Cracked, hardened mastic round windows on a block
  • Communal area joints that look neglected

Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies.
