Commercial sealant contractors in Meresborough

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. If you are dealing with frame sealant that has cracked, shrunk or pulled away and smeared sealant across finishes from a rushed job, we can help, on window and door perimeters, movement joints in walls and floors and washrooms and tea points alike. A specialist sealant contractor works differently from a general builder: in Meresborough, that means joint design, primers and backing rod as standard.

In Meresborough, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Work in smaller places such as Meresborough 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a few hours to several days on most single sites, depending on joint lengths and access. Smaller jobs around Meresborough can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Move anything stored against the joints
  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000

Related advice

Leave it or put it right?

Reactive resealing, a leak at a time, tends to cost more overall than a plan. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Around Meresborough, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Access often affects the price as much as the sealing: 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.

Why us?

  • Colour agreed before work starts
  • Joints cleaned back to sound surfaces
  • One phone line for London, the South East and Scotland
  • Work to your specification and the manufacturer’s guidance

Read how commercial sealant jobs are priced and our accreditations.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Act on the first lifting edges rather than waiting
  • Keep a record of which joints were resealed and when
  • Keep washroom and kitchen extraction working
  • Keep abrasive pads and scrapers off resealed joints

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. If that happens, phone 01277 525 020 or email drawings and photos and we will price putting it right.

Sealant installed at the same time typically fails in sequence. A few splits this year usually mean more next year. We’ll tell you which sealant joints need doing first and which can wait.

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

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 any of the following:

  • Cracking that needs a structural engineer to look at it
  • Broken glass or blown double-glazed units
  • Old mastic that tests positive for asbestos

If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Cost factors for sealant joints

A fixed quote reflects the actual work. It allows for:

  • How accessible the joints are
  • How much existing material needs removing
  • The size and state of each joint
  • Site requirements such as inductions and permits

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • Drawings or a marked-up plan, if available

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

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.

Commercial sealant contractors around Meresborough: how the place shapes the job

The sea is no more than about 3 miles from Meresborough. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are normally where failed joints show first. At least three named trading, business or retail sites lie within about 3 miles of Meresborough. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

If you look after units at a retail site such as Parkwood Shopping Centre, 0.7 miles to the west of Meresborough, shopfront perimeters and shop-fit joints are where a matched colour shows. For premises near Rainham (Kent) station, which lies north of Meresborough, footfall is part of the plan: work is phased so shops and offices keep trading. A hotel such as The Green Lion Hotel, 1 mile to the north of Meresborough, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Meresborough is about 2 miles south-east of Gillingham, in Medway. If you are looking for commercial sealant contractors in Meresborough, we can help, as we do across Medway. We work across 54 places in Medway, large and small. There’s a separate page for London, about 32 miles away.
