Mastic sealing in Smeeth

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

Why deal with it now?

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Smeeth, rather than one at a time. Photos of every joint help us quote for the whole job.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Mastic sealing in Smeeth, done properly

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve old repairs sealed over failed mastic and water getting in round frames after rain, across shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints. Facilities teams, main contractors and managing agents in Smeeth tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Owners and agents with buildings around smaller places such as Smeeth 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.

Our 12-month guarantee is about workmanship, not 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.

Mastic sealing in Smeeth: the local picture

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Smeeth lies roughly 53 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Blocks of flats and mixed-use buildings often cluster around stations such as Westenhanger station (to the south-east of Smeeth) and their window and balcony mastic tends to age at the same rate across a building. Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list.

Smeeth is about 5 miles east of Ashford, in Kent. Looking for mastic sealing in Smeeth? We can help, as we do across Kent. Smeeth is one of 931 places we cover in Kent for mastic joints. Sites around Brighton have their own page, roughly 52 miles from Smeeth.

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

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.

Maintenance after handover

To get the most from the new sealant:

  • Keep a record of when each building was resealed
  • Avoid piecemeal callouts where you can
  • Share your contractor requirements early
  • Have the asbestos survey to hand for older buildings

If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

Questions we are asked in Smeeth

Do you cover business parks and estates near Smeeth, such as Evegate Business Park?

Yes. Our area takes in Smeeth and its surroundings, with estates and business parks such as Evegate Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is Smeeth off your patch?

No. Places such as Smeeth are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.

What if the old mastic contains asbestos?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

When to call us in Smeeth

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

Most enquiries start with one or more of the following:

  • Water getting in round frames after rain
  • Brittle perimeter mastic across a building
  • Repeated reactive repairs to the same buildings
  • The same joint failures repeated across a portfolio

For owners of several units at places like Evegate Business Park, 0.8 miles south-west of Smeeth, one programme can deal with frame and external mastic across the lot.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Is the sealant right for the movement and the substrate?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For a building around Smeeth, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Failed mastic is removed and the faces taken back to sound, dry 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.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Tell staff and tenants when we’ll be in

Advice

What the job involves on each surface

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
