Why deal with it now?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. Resealing usually costs far less than renewal, though we’ll tell you honestly if the element itself is the problem. For buildings around smaller places like West End, 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.

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Why appoint us

  • A Constructionline member, so easy to vet
  • Fixed quotes based on photographs, drawings or a visit

Commercial sealant contractors in West End

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind. We look before we quote and tell you plainly if sealant won’t solve it. If you have black mould through washroom sealant that won’t clean off and shrunken sealant along kitchen worktops and splashbacks, we can put it right, on movement joints in walls and floors, window and door perimeters and washrooms and tea points alike. A specialist sealant contractor works differently from a general builder: in West End, that means joint design, primers and backing rod as standard.

A lot of what we do in West End is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Commercial sealant work around smaller places like West End tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Aftercare for building managers

For the best life from the joints:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Respect the cure time before reopening an area
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Check joints after other trades have worked nearby

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. Should something look amiss, you can phone 01277 525 020 or email a schedule or drawings and send a picture.

Sealant installed at the same time typically fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When to call us in West End

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.

Most enquiries start with something like this:

  • Messy, uneven beads from earlier work that let the building down
  • Gaps behind commercial kitchen worktops and sinks
  • Expansion joints with the sealant torn out
  • Earlier reseals applied straight onto the failed bead

Sites a few miles apart, such as St. Augustine's Business Park and John Wilson Industrial Estate, can share one programme and one point of contact.

Choosing a commercial sealant contractor

What West End’s businesses ask us to seal

West End sits close to the coast, within about 2 miles. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Where a frontage needs a particular colour, the product still has to suit that exposure. Four care or nursing homes sit less than 2 miles from West End. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean, often in colours that suit the décor.

Units at places like Buddy's Retail Park (3 miles south of West End) are refitted as brands change, and the joints have to suit each new scheme. For premises near Chestfield & Swalecliffe station, 1.3 miles to the north-west of West End, footfall is part of the plan: work is phased so shops and offices keep trading.

West End is about 2 miles south-west of Herne Bay, in Kent. Any commercial site in West End is covered. Across Kent, 931 places are covered, West End among them. For work in that direction, see our London page.

Postcode districts covered here: CT6 for sealant joints. Nearby places we also cover include Radfall (1 mile south-west), Chestfield (1 mile west), Swalecliffe (1 mile north-west), Hampton (2 miles north) and Tankerton (2 miles north-west). Nearby towns on our patch include Canterbury (5 miles south), Margate (13 miles east), Sittingbourne (15 miles west), Ramsgate (14 miles east), Broadstairs (15 miles east) and Faversham (9 miles west).

Landmarks near West End

We work on buildings around The Share And Coulter Public House, Curtis Wood and Herne Bay High School. The nearest railway station is Chestfield & Swalecliffe station, about 1.3 miles north-west of the centre. Other landmarks nearby include Whitstable and Tankerton Hospital (2 miles north-west) and Tankerton Castle (2.7 miles north-west). Not far away are West Blean and Thornden Woods.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a few hours to several days on most single sites, depending on joint lengths and access. For work around West End, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Common questions from West End clients

Does your area include sites such as St. Augustine's Business Park, near West End?

Yes. Our area takes in West End and its surroundings, with estates and business parks such as St. Augustine's Business Park included. A few photos and the unit address let us price the work.

Is West End off your patch?

No. Places such as West End are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Will the building have to shut during the work?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we’ll plan the job around it.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal
  • Leaks from pipework, wastes or valves (that’s plumbing)

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.
