About our commercial sealant contractors in North Street

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. Site teams most often ask us about external beads that have gone brittle and cracked and expansion joints with the sealant torn out, across movement joints in walls and floors, floor and threshold joints and external facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in North Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

Business units in the countryside around places like North Street are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Faulty windows rather than failed perimeter sealant
  • Water from a services leak rather than a joint
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Where we work in North Street

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

What North Street’s businesses ask us to seal

A 2-mile radius around North Street takes in a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading. North Street sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.

Offices and shops close to stations such as Faversham station (to the north of North Street) tend to be busy all day, so sealant work is planned around opening hours.

North Street is about 2 miles south of Faversham, in Kent. If you are looking for commercial sealant contractors in North Street, we can help. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, about 45 miles away.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around North Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  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

  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Keeping the joints sound

A few simple habits keep the new joints working:

  • Have extract fans checked so wet areas dry out
  • Keep a record of which joints were resealed and when
  • Report cracked or peeling sealant early
  • Make sure contractors see the asbestos survey before cutting out old mastic

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint. Leaving the area closed until then keeps the bead neat.

Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.

When to call us in North Street

A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds, which is why we look at the joint design as well.

What tends to prompt an enquiry:

  • External beads that have gone brittle and cracked
  • Expansion joints with the sealant torn out
  • Mouldy silicone around WCs, urinals and vanity tops
  • Earlier reseals applied straight onto the failed bead

In hotels such as Premier Inn Faversham Hotel (1.3 miles north of North Street), refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

What to look for in a quote

Choosing a commercial sealant contractor

How the quote is worked out

What shapes the price:

  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Location, for remote and island sites

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The postcode of the building
  • Any dates the work must fit around
  • Access details, including height
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or use the quote form.

Your questions answered

Is North Street off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Must a hotel around North Street close while you work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is the old sealant taken out first?

Full removal is part of every quote. A bead laid on old silicone peels away, so it isn’t something we do.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Can you handle sealant work across several sites?

Yes. We regularly take on multi-site work and planned maintenance programmes, priced site by site or as one programme.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. We can work to your instruction process and site rules.
