Commercial sealant contractors for Roughway sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Commercial mastic work in Roughway

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. Part of the job is telling you when the fix is something other than sealant, so budgets go where they’ll do some good. If you have sanitary sealant that has gone black and patchy and a top-up bead over failed sealant, now lifting, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Roughway it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A lot of what we do in Roughway is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Rural business units near smaller places such as Roughway are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The total length or number of joints
  • Joint width, depth and condition
  • Location, for remote and island sites
  • Access and working height

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Before you send an enquiry

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

  • A wide shot and a close-up of the area
  • The type of building and who uses it
  • Any specification or named product
  • Any dates the work must fit around

For a fixed quote, ring 01277 525 020 or send photos by email with the site address and an outline of the work. You can also send details through our quote form.

Sealant on show in Roughway’s commercial buildings

Two named trading, business or retail sites lie within about 3 miles of Roughway. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. 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.

On estates like The Alders Industrial Estate, 2.2 miles to the east of Roughway, the office and welfare end of each unit has its own sealant to maintain. Occupiers with premises at both The Alders Industrial Estate and Bourne Enterprise Centre could have the sealant at each handled under one quote.

Roughway is about 4 miles north-east of Tonbridge, in Kent. We cover commercial sites throughout Roughway, for single jobs and planned programmes alike. Roughway is one of 931 places in Kent on our list for sealant joints. Sites around London have their own page, roughly 25 miles from Roughway.

We cover the TN11 postcode districts. Just outside Roughway, we also work in Dunk's Green (1 mile west), Plaxtol (1 mile north-west), Swanton (1 mile east), West Peckham (2 miles east) and Claygate Cross (2 miles north). Nearby towns on our patch include Maidstone (9 miles east), Dartford (14 miles north), Sevenoaks (6 miles west), Royal Tunbridge Wells (8 miles south), Gravesend (13 miles north) and Tonbridge (4 miles south-west).

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. If others near Roughway need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Advice

What we are called out for in Roughway

Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.

Clients normally get in touch after noticing something like this:

  • Shrunken sealant along kitchen worktops and splashbacks
  • Water staining near frames, panels or ceilings
  • Earlier reseals applied straight onto the failed bead
  • Hardened, chalky sealant on south-facing or exposed elevations

Offices and shops close to stations such as Borough Green & Wrotham station (to the north of Roughway) tend to be busy all day, so sealant work is planned around opening hours.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Are they CHAS accredited or on Constructionline?
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Faulty windows rather than failed perimeter sealant
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • A failed roof covering or waterproofing membrane

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

Aftercare for building managers

After handover, a little attention goes a long way:

  • Keep abrasive pads and scrapers off resealed joints
  • Make sure ventilation in wet areas is switched on and working
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Keep barriers up until the new sealant has cured

We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Roughway: questions and answers

Is Roughway too far out for you?

No. Places such as Roughway are covered as much as the big towns. 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.

Do you offer colour-matched sealant for buildings in Roughway?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do you work directly for building managers?

Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. Tell us how you issue work and we’ll fit in.

Can you supply RAMS and insurance details?

The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

Does weather matter for sealant work?

It can, when the joints are outside. 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.

Can areas stay open during the work?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.
