Commercial sealant contractors for businesses in Forstal

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

Before we leave any area, 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. Rural sites near Forstal may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Let building users know which areas are affected
  • Move anything stored against the joints

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email the details over.

Advice

Commercial mastic work in Forstal

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. Most enquiries involve a top-up bead over failed sealant, now lifting and greasy, split joints in a kitchen or tea point, across floor and threshold joints, movement joints in walls and floors and washrooms and tea points. Most enquiries from Forstal start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In Forstal, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Rural business units near smaller places such as Forstal are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Signs you need commercial sealant contractors in Forstal

In wet areas the enemy is normally mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant; when mould is in the body of the sealant, no cleaner will shift it. Replacement with a sanitary anti-mould silicone is the lasting answer.

Look out for the following:

  • A top-up bead over failed sealant, now lifting
  • Gaps behind commercial kitchen worktops and sinks
  • Frame mastic that has hardened and come away from the wall
  • Weathered facade sealant that no longer flexes

Units at retail parks like Mid Kent Shopping Centre (1.2 miles south of Forstal) change hands and get refitted, with new joints at every frontage.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Make sure ventilation in wet areas is switched on and working
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Look at the sealant around anything that has been moved or replaced
  • Keep a record of which joints were resealed and when

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet. Your maintenance team can look at extract fans at the same time.

A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

Working on commercial sites near Forstal

Forstal is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. A 2-mile radius around Forstal takes in a number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, and the work can be phased so the rest of the hotel keeps trading.

Premises within reach of Aylesford station (to the west of Forstal) often have busy frontages where joints are seen by everyone passing. A business with units at Mid Kent Shopping Centre and South Aylesford Retail Park needn’t use two contractors for its sealant.

Honest limits

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

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Water from a services leak rather than a joint
  • Suspect materials that need testing and specialist removal

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

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

Forstal: questions and answers

Will you take on work at estates like Mid Kent Shopping Centre, close to Forstal?

Yes. Our area takes in Forstal and its surroundings, with estates and business parks such as Mid Kent Shopping Centre included. Photos and a short description are enough for a first look.

Do hotels near Forstal have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

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.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we will set out a timescale with the quote.

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: for instance 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.
