Commercial mastic work in Kent Street

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. Most enquiries involve earlier reseals applied straight onto the failed bead and damp patches where an external joint has failed, across external facade joints, washrooms and tea points and floor and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kent Street is the same: the right product in a properly prepared joint.

On a typical commercial building in Kent Street, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

A job in a smaller place like Kent Street is usually a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Looking after the joints

A few simple habits keep the new joints working:

  • Note dates and locations of sealant work for future planning
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Have extract fans checked so wet areas dry out

In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Planned replacement saves fielding the same complaint again and again.

When to bring in a specialist

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

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer.

Questions about Kent Street

Is Kent Street too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is Wheel Farm Business Park, near Kent Street, within your area?

Yes. We cover Kent Street and the area around it, including industrial estates, business parks and retail parks such as Wheel Farm Business Park. Photos and a short description are enough for a first look.

Which site documents can you send us?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Commercial sealant contractors around Kent Street: how the place shapes the job

Rainfall across the South East, Kent Street included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. A 2-mile radius around Kent Street takes in a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes.

Shopping centres and retail parks such as Hastings Retail Park, 1.7 miles to the south of Kent Street, see a steady turnover of shop fits, each leaving joints where colour and finish matter. Offices at parks like Wheel Farm Business Park (to the east of Kent Street) have receptions, kitchens and glazed partitions where a tidy joint matters.

When to call us in Kent Street

Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.

Clients usually get in touch after noticing something like this:

  • Black mould through washroom sealant that won’t clean off
  • Untidy joints in a reception, shop floor or lobby
  • A top-up bead over failed sealant, now lifting
  • Gaps behind commercial kitchen worktops and sinks

Premises within reach of Battle station (2.2 miles west of Kent Street) often have busy frontages where joints are seen by everyone passing.

Before you book anyone

  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Kent Street are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
  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. 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. Finished joints are checked with you and handed over with our 12-month guarantee.

Before we start on site

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open
