  • Broken glass or blown double-glazed units
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

About our commercial sealant contractors in Eastry

Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Eastry, ring 01277 525 020 or send photos by email with the site addresses. If you’re dealing with expansion joints with the sealant torn out and leaks that seem to come through a sealant line, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Eastry is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

We price commercial jobs in Eastry from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Small businesses near places like Eastry frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Eastry: questions and answers

Does your area include sites such as Birnham Farm Business Centre, near Eastry?

Yes. We cover Eastry and the area around it, including industrial estates, business parks and retail parks such as Birnham Farm Business Centre. Photos and a short description are enough for a first look.

Can you match sealant colours for premises in Eastry?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you cover Eastry?

Yes. Eastry falls within our area, and you can call the office on 01277 525 020 or send details through our quote form to get started.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts.

Who decides which product is used?

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.

Sealant on show in Eastry’s commercial buildings

Rainfall across the South East, Eastry included, is lower than in many parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. At about 63 miles from central London, Eastry is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Parks like Birnham Farm Business Centre (to the north-west of Eastry) see tenants come and go, and every move-in brings joints to seal.

Eastry is about 4 miles north-west of Deal, in Kent. We cover Eastry, with the same fixed quotes and 12-month guarantee as everywhere else. Our Kent coverage takes in 931 places. London is covered too, some 63 miles away.

Business premises anywhere in CT13 are within our area. For a building on High Street, Swaynes Way and Wheelwrights Way or nearby, send details and we will quote for sealant joints. Just outside Eastry, we also work in Buttsole (1 mile south), Statenborough (1 mile north-east), Ham (1 mile east), Woodnesborough (1 mile north) and Felderland (1 mile north-east). Nearby towns on our patch include Canterbury (10 miles west), Margate (10 miles north), Dover (7 miles south), Folkestone (13 miles south-west), Ramsgate (8 miles north-east) and Broadstairs (10 miles north-east).

On site: what to expect

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from part of a day on a short run of joints to several weeks on a large phased package. Work in places the size of Eastry is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we’ll be in
  • Send any specification or drawings in advance

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

What the job involves on each surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement.

Do you need commercial sealant contractors in Eastry?

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.

Site and facilities staff are often the first to spot these:

  • Water staining near frames, panels or ceilings
  • Layers of sealant, all of them failing
  • Wall and floor joints that have lost their seal
  • Black mould through washroom sealant that won’t clean off

For premises near Sandwich station (2.3 miles north-east of Eastry), footfall is part of the plan: work is phased so shops and offices keep trading.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Are they CHAS accredited or on Constructionline?
  • How long is the guarantee, and what does it include?
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

Cost factors for sealant joints

What shapes the price:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • How accessible the joints are
  • Backing rod, priming and other preparation

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

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

  • Access details, including height
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area

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

Work for main contractors and building owners

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

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
