Sealant applicators in Grays

Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas and you can also call 01277 525 020 or email drawings and photos to talk it through. If the joints need seeing in person, a site visit comes first. The enquiries we see most involve a top-up bead over failed sealant, now lifting and greasy, split joints in a kitchen or tea point, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Grays is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

The most common commercial job in Grays is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

In towns of Grays’s size, shops and offices often occupy older buildings with later extensions and new shopfronts. Joints where brick or render meets a newer frame or panel move differently, so the sealant has to suit both sides, in a colour that suits the frontage.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Shops, offices and hotels in and around Grays

The sea is no more than about 3 miles from Grays. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. Sea-facing elevations are normally where failed joints show first. Grays lies roughly 18 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Shopping centres and retail parks such as Lakeside Shopping Centre, 2.1 miles to the west of Grays, see a steady turnover of shop fits, each leaving joints where colour and finish matter. If you have premises on more than one site, say at Thurrock Park Industrial Estate and London Distribution Park, one contractor and one quote can cover both. On estates like Thurrock Park Industrial Estate, 1.1 miles south-east of Grays, the office and welfare end of each unit has its own sealant to maintain.

Grays is about 5 miles north-east of Dartford, in Thurrock. Across the RM17 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Thurrock, 27 places are covered, including Grays. For work in that direction, see our London page, about 18 miles away.

Postcode districts covered here: RM17, RM16, RM20 and RM18. If your site is on London Road, College Avenue and Cresthill Avenue or close by, we can quote for sealant joints.

Nearby places we also cover include Little Thurrock (1 mile north-east), Chafford Hundred (1 mile north-west), Orsett Heath (1 mile north-east), North Stifford (2 miles north-west) and Chadwell St Mary (2 miles east) for sealant joints.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Surface by surface

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Washrooms and toilets

Mould that has grown into washroom sealant can’t usually be cleaned out. Replacement is the fix: strip, clean, dry and reseal.

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Deal with small splits before they become leaks
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Keep washroom and kitchen extraction working

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We’ll tell you which sealant joints need doing first and which can wait.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Most work in Grays is one building at a time: a school, a unit, an office or a block. Your photographs, drawings or a site visit come first, followed by a fixed quote.

  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. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Grays: questions and answers

Will you take on work at estates like Thurrock Park Industrial Estate, close to Grays?

Yes. We cover Grays and the area around it, including industrial estates, business parks and retail parks such as Thurrock Park Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Does a hotel in Grays need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Which site documents can you send us?

Send your site requirements with the enquiry. From you, we will need the asbestos information for older buildings and any site rules.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do you keep disruption to occupiers down?

It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we’ll work around it.

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How long do sealant joints last?

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

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: 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.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • The site’s rules and procedures
  • Location, for remote and island sites
  • Phasing around occupants
  • Joint width, depth and condition

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Any specification or named product
  • Your programme or deadline
  • The asbestos register, for older buildings
  • The type of building and who uses it

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.
