Mastic sealing for Kenardington sites

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

What happens if it’s left?

Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. For buildings around smaller places like Kenardington, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Why us?

  • Coloured sealants to suit the setting, where available
  • Workmanship guaranteed for 12 months
  • Clear, fixed quotes
  • Fully insured

Mastic sealing for commercial buildings in Kenardington

There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. If you have occupiers reporting cold air round windows and brittle perimeter mastic across a building, we can put it right, on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells alike. Whoever orders the work in Kenardington, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions near places like Kenardington often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Surface by surface

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

External movement joints

Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Leaks from above rather than through a joint
  • Asbestos-containing sealant, which we don’t remove
  • Frames that are rotten, warped or broken

Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly before you book.

What we seal

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

Do you need mastic sealing in Kenardington?

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.

Look out for the following:

  • Estate-wide sealant that is simply worn out
  • A mix of products and colours from past repairs
  • Leaks at window and door perimeters
  • Window mastic that has split and shrunk

For owners of several units at places like Meadow View Business Park, 2.7 miles to the east of Kenardington, one programme can deal with frame and external mastic across the lot.

Before you book anyone

  • How they handle RAMS and site documents
  • Their approach to joint depth and backing
  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

What affects the price in Kenardington

The price varies from site to site. It mainly depends on:

  • Phasing around occupants
  • Distance, for remote addresses
  • Access and working height
  • How much existing material needs removing

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Sending details for a quote

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

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • The postcode of the building
  • A wide shot and a close-up of the area

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send photos by email.

For owners and agents in Kenardington

Kenardington lies roughly 50 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Kenardington included, is lower than in many parts of the UK. 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.

Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you look after a block within reach of Appledore (Kent) station, 1.8 miles south of Kenardington, frame and balcony mastic can be renewed on one programme.

Kenardington is about 6 miles south-west of Ashford, in Kent. Commercial clients in Kenardington use us for work on mastic joints. We work across 931 places in Kent, large and small. Our Brighton page has more on work in that area, about 44 miles away.

If your building is just outside Kenardington, we cover Hamstreet (2 miles east), Orlestone (2 miles north-east), Snargate (3 miles south-east), Bromley Green (3 miles north-east) and Ruckinge (3 miles east). A short drive away, we cover Ashford (6 miles north-east), Folkestone (15 miles east), Hythe (12 miles east), Tenterden (5 miles west), Cheriton (14 miles east) and Kennington (8 miles north-east).

Questions we’re asked in Kenardington

Will you take on a block within reach of Appledore (Kent) station?

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

Is Kenardington too far out for you?

Not at all. Kenardington is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

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.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

Will residents or tenants be disturbed?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Kenardington, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Preparing the site

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or send photos by email to discuss it first.
