Sealant applicators in South Stour

Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve greasy, split joints in a kitchen or tea point and layers of sealant, all of them failing, on window and door perimeters, kitchen worktops and splashbacks and floor and threshold joints. A specialist sealant contractor works differently from a general builder: in South Stour, that means joint design, primers and backing rod as standard.

The most common commercial job in South Stour is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

In and around smaller places such as South Stour, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What South Stour’s businesses ask us to seal

At least three named trading, business or retail sites lie within about 3 miles of South Stour. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies. South Stour sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Ashford International station (2.8 miles north-west of South Stour), footfall is part of the plan: work is phased so shops and offices keep trading. Sites a few miles apart, such as Bliby Business Centre and Ashford Retail Park, can share one programme and one point of contact.

South Stour is about 3 miles south-east of Ashford, in Kent. Anywhere in TN25, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 931 places across Kent fall within our area, including South Stour. There’s a separate page for Brighton, roughly 49 miles from South Stour.

Anyone looking for commercial sealant contractors in TN25 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your building is just outside South Stour, we cover Mersham (1 mile north-east), Sevington (2 miles north), Hinxhill Park (2 miles north), Ridgeway (3 miles north-east) and Hinxhill (3 miles north-east). Bigger towns within reach include Ashford (3 miles north-west), Canterbury (14 miles north-east), Folkestone (11 miles east), Faversham (14 miles north), Hythe (8 miles east) and Davington (15 miles north).

When to call us in South Stour

If sealant tears through its centre, it has failed cohesively. That typically means the joint stretched further than the product could cope with: a bead laid too thin, an over-stretched joint or the wrong movement class. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.

If one of these sounds familiar, it’s time for a closer look:

  • Damp patches where an external joint has failed
  • Expansion joints with the sealant torn out
  • Earlier reseals applied straight onto the failed bead
  • Weathered facade sealant that no longer flexes

Parks like Bliby Business Centre, 0.6 miles to the south-west of South Stour, see tenants come and go, and every move-in brings joints to seal.

What to look for in a quote

  • Proof of insurance
  • Can the work be phased to keep areas open?
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Water from a services leak rather than a joint
  • Roof leaks that only look like a joint problem

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

  • External facade joints
  • Washrooms and tea points
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • Kitchen worktops and splashbacks

What sets the cost

We price every job individually. The things that drive the figure:

  • Access and working height
  • Removal of failed or old sealant
  • Phasing around occupants
  • Which sealant the job calls for

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Any dates the work must fit around
  • The postcode of the building
  • The product your specification calls for
  • Clear photos of the problem areas

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around South Stour, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits

Advice

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

FAQs: South Stour

Is Bliby Business Centre, near South Stour, within your area?

Yes. Estates, retail parks and business parks around South Stour, Bliby Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Can the sealant on our South Stour premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Is failed sealant stripped out, or sealed over?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.

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.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you take on work for an FM or managing agent?

Yes. Use our quote form to send the site details, or phone or email us, and we will confirm any paperwork you need with the quote.

What happens if it’s left?

Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation. Converted and older buildings near places like South Stour tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

A quote for sealant joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
