Commercial sealant contractors in Parkeston

We’ve applied sealant on commercial sites for over 20 years: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on movement joints in walls and floors, washrooms and tea points and external facade joints, and what we’re called in for most is gaps behind commercial kitchen worktops and sinks and frame sealant that has cracked, shrunk or pulled away. Most enquiries from Parkeston 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.

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

Work in smaller places such as Parkeston tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Our workmanship is guaranteed for 12 months, in Parkeston as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus 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.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Parkeston, 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 begin with whatever information you have, whether that’s photos, a drawing or a list of locations, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  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. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000

Surface by surface

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Counters, display units, shopfront frames and floor trims all need a neat line. We will confirm the colours available for the specified product.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, and we will confirm the colours available for the specified product.

Common questions from Parkeston clients

Our building in Parkeston is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Will our hotel in Parkeston need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

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. Internal work is rarely affected.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Which site documents can you send us?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Do you cover Parkeston?

Yes. Parkeston is in our area and the rest of Essex. For a quote, call 01277 525 020 or email us.

What we are called out for in Parkeston

Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

Look out for the following:

  • Messy, uneven beads from earlier work that let the building down
  • External beads that have gone brittle and cracked
  • Shrunken sealant along kitchen worktops and splashbacks
  • Black mould through washroom sealant that won’t clean off

Premises within reach of Harwich International station, under half a mile to the north of Parkeston, often have busy frontages where joints are seen by everyone passing.

Questions to ask before you book

  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Broken glass or blown double-glazed units
  • Walls or slabs moving more than any sealant can take

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Surfaces we seal

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

Commercial sealant contractors around Parkeston: points for this area

With the shore within about 1 mile, Parkeston counts as a coastal location. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. We choose a product rated for the exposure, then confirm the colours available for it. Rainfall across the South East, Parkeston 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.

A hotel such as Tower Hotel (1 mile south-east of Parkeston) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Respect the cure time before reopening an area
  • Check joints after other trades have worked nearby
  • Put external and wet-area joints on a regular inspection round
  • Make sure ventilation in wet areas is switched on and working

We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
