Questions about Greenstead

Is Greenstead too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Must a hotel around Greenstead close while you work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

Can you supply RAMS and insurance details?

We will 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.

Could the old sealant in an older building contain asbestos?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.

Sealant specialists in Greenstead

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. If you have mouldy silicone around WCs, urinals and vanity tops and earlier reseals applied straight onto the failed bead, we can put it right, on floor and threshold joints, external facade joints and window and door perimeters alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Greenstead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

We price commercial jobs in Greenstead from photos, drawings or a site visit, and the scope is set out in writing.

Places like Greenstead tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Shops, offices and hotels in and around Greenstead

The 3 miles around Greenstead take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. Greenstead has a good number of hotels close by, all within 2 miles. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.

Premises within reach of Hythe station (to the south-west of Greenstead) often have busy frontages where joints are seen by everyone passing. For a hotel such as The Rose And Crown Hotel, which lies west of Greenstead, the colour of a joint at the bar or the bath matters to the look of the room.

Greenstead is about 2 miles east of Colchester, in Essex. Anywhere in CO4, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Essex, 644 places are covered, Greenstead among them. London is covered too, around 52 miles from Greenstead.

Common problems we fix in Greenstead

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

What tends to prompt an enquiry:

  • Black mould through washroom sealant that won’t clean off
  • Window and door perimeter joints that have cracked open
  • Movement joints packed with grit and debris
  • Greasy, split joints in a kitchen or tea point

If you have premises on more than one site, say at Hunwicke Shopping Centre and Moorside Business Park, one contractor and one quote can cover both.

Before you book anyone

  • How the existing material will be dealt with
  • The terms of the workmanship guarantee
  • Proof of insurance
  • Will CSCS-carded applicators be on site?

Our contractor checklist

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Structural cracks or movement the joints weren’t designed for
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Quoting for work in Greenstead

These are the things that shape the price:

  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Removal of failed or old sealant
  • Phasing around occupants

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.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Anything awkward about access or site hours

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or send photos by email to discuss it first.
