About our coloured sealant in Thundersley

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints on sites in Thundersley. On resealing, matching the existing colour is often as important as the seal itself. Most enquiries involve a run of joints in mismatched shades and dirty, discoloured joints in public areas, across shop-fit joinery and counters, natural stone and brick and hotel bathrooms and public areas. Most enquiries from Thundersley start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Many businesses in towns like Thundersley work from older buildings that have been altered more than once. Where old meets new there are junctions between brick, render, timber and aluminium, and each needs the right sealant, in a colour that suits the frontage.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Stopping sealant from ever changing colour outdoors
  • Paintable products in joints they aren’t suited to
  • Repairing damaged frames or cladding

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Where we work in Thundersley

  • Cladding panels
  • Hotel bathrooms and public areas
  • Office fit-out finishes
  • Powder-coated and anodised frames
  • Shop-fit joinery and counters
  • Natural stone and brick

What happens if it’s left?

A failed joint lets in water and dirt, whatever colour it is. Water through a split seal can stain or damage the surfaces next to it. In a town like Thundersley, a split, stained or mouldy joint is often the first thing visitors notice. Renewing it keeps the building looking cared for.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Constructionline member
  • Colours chosen to suit frames, cladding or finishes where possible
  • Fully insured, including public liability cover
  • CSCS-carded applicators

Questions we’re asked in Thundersley

Do you offer colour-matched sealant for buildings in Thundersley?

Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photos and we will confirm what’s available for the product.

Which documents can you supply for work in Thundersley?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Cost factors for colour-matched joints

What shapes the price:

  • The total length or number of joints
  • How much existing material needs removing
  • Which sealant the job calls for
  • Phasing around occupants

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

However big the job, these details speed things up:

  • The product your specification calls for
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or use the quote form.

Coloured sealant in Thundersley: the local picture

Thundersley is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Central London is about 29 miles from Thundersley. 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.

A business with units at Manor Trading Estate and Towerfields Business Park needn’t use two contractors for its sealant. If you run a unit on an estate such as Manor Trading Estate, which lies north-west of Thundersley, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Offices and shops close to stations such as Rayleigh station, 1.7 miles to the north-east of Thundersley, tend to be busy all day, so sealant work is planned around opening hours.

Thundersley is about 3 miles north of Canvey Island, in Essex. Across the SS7 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Essex, 644 places are covered, Thundersley among them. London is covered too, around 29 miles from Thundersley.

If you need coloured sealant in SS7 and SS6, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Streets here include Thundersley Church Road, Church Road and London Road, and sites on any of them can send details for a fixed quote.

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If you have more than one building in Thundersley, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. We remove the masking and walk the finished joints with you.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits
