Commercial sealant contractors in Walter's Green

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike. If you’re dealing with greasy, split joints in a kitchen or tea point and smeared sealant across finishes from a rushed job, we can help, on kitchen worktops and splashbacks, window and door perimeters and external facade joints alike. One point of contact handles commercial sealant work in Walter's Green from the first photographs to the final walk-round, whether it’s one building or several.

Occupied buildings in Walter's Green need the work phased: we agree the order with you and hand back each area with its cure time.

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

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Commercial premises in Walter's Green

Walter's Green is about 27 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all. Walter's Green sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For tenants and agents on sites such as Speldhurst Business Park, 2.4 miles to the east of Walter's Green, office fit-outs, reception joints and window perimeters are the usual sealant work. Premises within reach of Ashurst Kent station (to the south of Walter's Green) often have busy frontages where joints are seen by everyone passing.

Walter's Green is about 5 miles west of Royal Tunbridge Wells, in Kent. Our applicators travel to Walter's Green for work on sealant joints. We work across 931 places in Kent. Brighton is covered too, some 25 miles away.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

After the work

Keep the joints in good shape with a few simple steps:

  • Check sealant as part of routine building inspections
  • Keep a record of which joints were resealed and when
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Look at the sealant around anything that has been moved or replaced

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, speak to us on 01277 525 020 or email the details over and we will price putting it right.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

What affects the price in Walter's Green

Each job is priced on its own details. The main factors are:

  • Phasing around occupants
  • How much existing material needs removing
  • The product specified
  • Any access equipment needed

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

We can often quote from photos and a few details. Please tell us:

  • Photos of the joints, close up and from further back
  • Any specification or named product
  • Anything awkward about access or site hours
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or send details through our quote form.

Questions about Walter's Green

Is Walter's Green off your patch?

Not at all. Walter's Green is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work at a site such as Speldhurst Business Park, by Walter's Green?

Yes, sites like Speldhurst Business Park are within our area, along with the rest of Walter's Green. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you hold CHAS accreditation?

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

What do you need from us to quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

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.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Suspect materials that need testing and specialist removal
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Misted, cracked or failed glazing units (a glazier’s job)

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.

Joints and surfaces we work on

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

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. Smaller jobs around Walter's Green can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Before we start on site

  • Tell us which areas need to stay in use
  • Send your site hours and access windows
  • Warn occupants and staff about the work
