Commercial sealant contractors in Richborough Port

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have frame mastic that has hardened and come away from the wall and earlier reseals applied straight onto the failed bead, we can help, on external facade joints, window and door perimeters and floor and threshold joints alike. A single leaking joint is often how a building in Richborough Port first comes to us: we look at the rest while we’re there and tell you what we find.

Occupied buildings in Richborough Port need the work phased: we agree the order with you and hand back each area with its cure time.

A job in a smaller place like Richborough Port is typically a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the quote is worked out

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

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • A wide shot and a close-up of the area
  • The site address and postcode

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send photos by email.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • A dripping trap, valve or pipe behind a fitting
  • Broken glass or blown double-glazed units
  • A failed roof covering or waterproofing membrane

If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.

Where we work in Richborough Port

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

What the job involves on each surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement.

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Richborough Port are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  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. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • Confirm the product named in the specification
  • Make sure the joints can be reached

Advice

Leave it or put it right?

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, and they’re where most failures begin. It shows over the following seasons rather than at handover. Halls, stores and units around places like Richborough Port may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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.

Questions about Richborough Port

Can you work at a site such as Old Timber Yard Industrial Estate, by Richborough Port?

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

Is Richborough Port off your patch?

Not at all. Richborough Port is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

How is commercial sealant work priced?

The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.

Can one contractor look after sealant on all our buildings?

Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
