Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Deal with small splits before they become leaks
  • Keep a record of which joints were resealed and when
  • Make sure ventilation in wet areas is switched on and working
  • Don’t let cleaning or traffic back on before the cure time is up

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth. Keeping signs or barriers up until then protects the finish.

Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.

Sealant applicators in Thorington Street

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in Thorington Street, the quickest start is to phone 01277 525 020 or email the details over with a list of addresses. We work on washrooms and tea points, external facade joints and movement joints in walls and floors, and the usual reasons a site gets in touch are black mould through washroom sealant that won’t clean off and expansion joints with the sealant torn out. A single leaking joint is often how a building in Thorington Street first comes to us: we look at the rest while we are there and tell you what we find.

Quotes for commercial sealant in Thorington Street can come from photos and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

In and around smaller places such as Thorington Street, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to call us in Thorington Street

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.

These are often picked up first by site or facilities staff:

  • Expansion joints with the sealant torn out
  • External beads that have gone brittle and cracked
  • Mouldy silicone around WCs, urinals and vanity tops
  • Frame mastic that has hardened and come away from the wall

Parks like Langham Barns Business Centre, 2.8 miles to the south of Thorington Street, see tenants come and go, and every move-in brings joints to seal.

What to look for in a quote

  • The terms of the workmanship guarantee
  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS

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

Thorington Street is about 55 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site. 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.

For any commercial premises in Thorington Street, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a few hours to several days on most single sites, depending on joint lengths and access. For work around Thorington Street, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. You send photographs, drawings or a list of the joints and areas involved.
  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. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  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.

What we need from you

  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send photos by email.

Questions about Thorington Street

Do you cover business parks and estates near Thorington Street, such as Langham Barns Business Centre?

Yes. Our area takes in Thorington Street and its surroundings, with estates and business parks such as Langham Barns Business Centre included. Send details of the unit and the work through our quote form for a quick quote.

Do you offer colour-matched sealant for buildings in Thorington Street?

Yes, we can usually get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How do you keep disruption to occupiers down?

We phase the work so parts of the building stay open. Tell us your site hours and access windows and we will plan around them.

Could the old sealant in an older building contain asbestos?

It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Why deal with it now?

On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation. It shows over the following seasons rather than at handover. For buildings around smaller places like Thorington Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
