How we handle mastic sealing in Capel

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Capel carry our 12-month guarantee. We work on communal kitchens and washrooms, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are communal area joints that look neglected and movement joints with sealant missing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Capel it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners and agents with buildings around smaller places such as Capel tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

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 spell out the cover before we begin.

Blocks and managed buildings in Capel

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Capel lies roughly 29 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.

Older community buildings, Church of St Thomas à Becket among them, often have frames of mixed ages whose mastic varies. If you look after a block within reach of Paddock Wood station, 2 miles to the east of Capel, frame and balcony mastic can be renewed on one programme. If you own or manage units on a site such as Eldon Way Industrial Estate, 1.8 miles east of Capel, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Capel is about 3 miles south-east of Tonbridge, in Kent. Across the TN12 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Capel is one of 931 places in Kent on our list for mastic joints. For work in that direction, see our London page (29 miles or so).

Anyone looking for mastic sealing in TN12 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Leaks from above rather than through a joint
  • Masonry that has broken away beside the joint
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Where we work in Capel

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

Commercial clients in Capel

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking one or more days per building, depending on the joint lengths and the access. Rural sites near Capel may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Before we start on site

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Flag any permit to work we will need

Ask for a quote

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

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

How the quote is worked out

Before we quote, we look at:

  • Joint width, depth and condition
  • The product specified
  • How accessible the joints are
  • Working within restricted access windows

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.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The postcode of the building
  • What the building is and how it’s used
  • The product your specification calls for
  • Anything awkward about access or site hours

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

FAQs: Capel

Do you work for managing agents with blocks near Paddock Wood station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Does your area include sites such as Eldon Way Industrial Estate, near Capel?

Yes, sites like Eldon Way Industrial Estate are within our area, along with the rest of Capel. Photos and a short description are enough for a first look.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Do you work in Capel?

Yes. Capel is in our area. For a quote, speak to us on 01277 525 020 or email a schedule or drawings.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Can people stay in the building while you reseal?

The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

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 will confirm the approach in the quote.

Leave it or put it right?

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Capel, rather than one at a time. Send photographs of each area and we will quote for the lot.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
