Commercial sealant contractors for commercial buildings in Troy Town

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. The enquiries we see most involve a top-up bead over failed sealant, now lifting and wall and floor joints that have lost their seal, on external facade joints, floor and threshold joints and washrooms and tea points. Searching for sealant specialists in Troy Town? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In an occupied building in Troy Town, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Business units in the countryside around places like Troy Town are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email us and we will arrange a return visit.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. If others near Troy Town need work, visits can be combined. A fixed quote is given before anything starts.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  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.

Before we start on site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Agree which areas must stay open

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 email drawings and photos.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • The site’s rules and procedures

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • When you need the work done
  • Access details, including height
  • Whether an asbestos survey exists
  • The site address and postcode

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Questions we are asked in Troy Town

What paperwork can you provide for a job in Troy Town?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Troy Town too far out for you?

Not at all. Troy Town is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

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 will confirm the curing time on the day.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • A dripping trap, valve or pipe behind a fitting
  • Walls or slabs moving more than any sealant can take
  • Faulty windows rather than failed perimeter sealant

If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

What we seal

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

What the job involves on each surface

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.

Washrooms and toilets

Mould that has grown into washroom sealant can’t normally be cleaned out. Replacement is the fix: strip, clean, dry and reseal.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

When to call us in Troy Town

Resealing over the top is a false economy we come across often. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Site and facilities staff are often the first to spot these:

  • Movement joints packed with grit and debris
  • Water staining near frames, panels or ceilings
  • Black mould through washroom sealant that won’t clean off
  • Shrunken sealant along kitchen worktops and splashbacks

A hotel such as The Albion Hotel, 0.8 miles east of Troy Town, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Questions to ask before you book

  • The named product and why it was chosen
  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?

Questions to ask before you appoint anyone
