Commercial sealant contractors across Bluetown

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Bluetown are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  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. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand

Sealant specialists in Bluetown

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on movement joints in walls and floors, floor and threshold joints and external facade joints, and the failures we are asked to look at most are earlier reseals applied straight onto the failed bead and frame mastic that has hardened and come away from the wall. Facilities teams, main contractors and managing agents in Bluetown tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In Bluetown, as anywhere, the first joints to go are typically 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 Bluetown 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Old mastic that tests positive for asbestos
  • A failed roof covering or waterproofing membrane
  • Cracking that needs a structural engineer to look at it

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

What we seal

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

Common questions from Bluetown clients

Can you supply sealant in our brand colour for a site in Bluetown?

Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.

Is Kent Science Park, near Bluetown, within your area?

Yes. We cover Bluetown and the area around it, including industrial estates, business parks and retail parks such as Kent Science Park. A few photos and the unit address let us price the work.

Do you work directly for building managers?

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

How long does a job like this 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.

What about asbestos in old mastic?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

How do you keep disruption to occupiers down?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing, until its cure time has passed.

How long before the joints can be used?

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

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Frontages, fit-outs and joints in Bluetown

The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. At about 39 miles from central London, Bluetown is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings.

Premises within reach of Sittingbourne station, 3.6 miles to the north of Bluetown, often have busy frontages where joints are seen by everyone passing.

Building owners, agents and FMs in Bluetown

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Bluetown can sit alongside others in a wider programme.

Do you need commercial sealant contractors in Bluetown?

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. Once it stiffens, the joint opens up at the next big temperature swing.

Clients usually get in touch after noticing one or more of the following:

  • Layers of sealant, all of them failing
  • Smeared sealant across finishes from a rushed job
  • Sanitary sealant that has gone black and patchy
  • Weathered facade sealant that no longer flexes

If you run an office at a site such as Kent Science Park, 1.8 miles north-west of Bluetown, the sealant at reception desks, tea points and frames ages with each fit-out.

Choosing a commercial sealant contractor

What the job involves on each surface

Washrooms and toilets

Mould that has grown into washroom sealant can’t typically be cleaned out. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
