Questions we’re asked in Crow's Green

Does your area include sites such as Goulds Farm Industrial Estate, near Crow's Green?

Yes. Our area takes in Crow's Green and its surroundings, with estates and business parks such as Goulds Farm Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Can the sealant on our Crow's Green premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photos and we will confirm what’s available for the product.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Could the old sealant in an older building contain asbestos?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

After the work

For the best life from the joints:

  • Act on the first lifting edges rather than waiting
  • Note dates and locations of sealant work for future planning
  • Keep washroom and kitchen extraction working
  • Ask fit-out and M&E contractors to report any sealant they disturb

Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just phone 01277 525 020 or email a schedule or drawings for a quote.

Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.

Building owners, agents and FMs in Crow's Green

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

What affects the price in Crow's Green

Each job is priced on its own details. The main factors are:

  • The size and state of each joint
  • Which sealant the job calls for
  • How accessible the joints are
  • How much existing material needs removing

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • What the building is and how it’s used
  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send details through our quote form.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Cracking that needs a structural engineer to look at it
  • Old mastic that tests positive for asbestos
  • Misted, cracked or failed glazing units (a glazier’s job)

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Where we work in Crow's Green

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

Working on commercial sites near Crow's Green

Central London is about 37 miles from Crow's Green. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Crow's Green sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Shops and cafés around stations like Braintree station (4.7 miles south-east of Crow's Green) trade from early, so work is timed around them. Industrial estates such as Goulds Farm Industrial Estate, 2.6 miles south-east of Crow's Green, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

What the job involves on each surface

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Crow's Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Share the asbestos register for older buildings
  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in
