Mastic sealing in Saltwood

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

Commercial clients in Saltwood

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Mastic sealing in Saltwood, done properly

For blocks and buildings in Saltwood and across Kent, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve communal area joints that look neglected and failed external movement joints, on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks. Whether you call it commercial sealant work, mastic application or joint sealing, in Saltwood it comes down to the same thing: the right product in a properly prepared joint.

Owners and agents with buildings around smaller places such as Saltwood tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Frames that are rotten, warped or broken
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Water coming in from the roof or rainwater goods

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

What we seal

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

Surface by surface

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.

Why act early in Saltwood

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. For buildings around smaller places like Saltwood, 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.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Common questions from Saltwood clients

Can being near the sea in Saltwood affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

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

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed 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 communal access is kept open.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Is Saltwood in your area?

Yes. Sites across Saltwood are covered, with one number for every area we cover.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Does weather matter for sealant work?

For external joints, 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. Internal work is rarely affected.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a day or two for a single block, longer for an estate programme. For work around Saltwood, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  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. Buildings are completed in turn.

What we need from you

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

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 where general trades tend to cut corners.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Looking after buildings in and around Saltwood

Saltwood lies within about 1 mile of the sea. On buildings near the shore, the side facing the weather typically needs its mastic renewed first; plan inspections around that. Saltwood is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Blocks of flats and mixed-use buildings often cluster around stations such as Sandling station (0.9 miles north-west of Saltwood) and their window and balcony mastic tends to age at the same rate across a building. Schools and community buildings such as Saltwood CofE Primary School need frame and external mastic kept sound like any building. For owners of several units at places like Shorncliffe Industrial Estate, 2.8 miles to the east of Saltwood, one programme can deal with frame and external mastic across the lot.

Saltwood is about 1 mile north of Hythe, in Kent. Looking for mastic sealing in Saltwood? We can help. We work across 931 places in Kent. Sites around Brighton have their own page, roughly 55 miles from Saltwood.
