About our commercial sealant contractors in Ash

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: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in Ash, the quickest start is to give us a call on 01277 525 020 or use the quote form with a list of addresses. The enquiries we see most involve messy, uneven beads from earlier work that let the building down and external beads that have gone brittle and cracked, across washrooms and tea points, kitchen worktops and splashbacks and floor and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Ash it comes down to the same thing: the right product in a properly prepared joint.

On a typical commercial building in Ash, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Places like Ash tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email us and we’ll come back to it.

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Ash, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Share the asbestos register for older buildings
  • Flag any permit to work we will need

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Commercial clients in Ash

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Common problems we fix in Ash

A split down the middle of the bead tells a different story. That normally means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way.

If one of these sounds familiar, it’s time for a closer look:

  • Frame sealant that has cracked, shrunk or pulled away
  • Earlier reseals applied straight onto the failed bead
  • Gaps behind commercial kitchen worktops and sinks
  • Movement joints packed with grit and debris

Parks like Birnham Farm Business Centre, 1.4 miles to the south-east of Ash, see tenants come and go, and every move-in brings joints to seal.

Comparing quotes

  • What site paperwork they can supply
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it
  • Health and safety accreditation such as CHAS

Choosing a commercial sealant contractor

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

What the job involves on each surface

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement.

Questions we are asked in Ash

Do you cover business parks and estates near Ash, such as Birnham Farm Business Centre?

Yes. We cover Ash and the area around it, including industrial estates, business parks and retail parks such as Birnham Farm Business Centre. A few photographs and the unit address let us price the work.

Can the sealant on our Ash premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

How is commercial sealant work priced?

Send what you have, even a few photographs and rough lengths. Questions or a site visit follow where needed, then a fixed quote.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.

Will you just go over the old sealant?

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.

Commercial premises in Ash

The 3 miles around Ash take in two named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. At about 61 miles from central London, Ash is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

Refits at hotels like The Lion Hotel (to the south-east of Ash) bring joints at vanity tops, bars and reception desks that guests see every day. Shops and cafés around stations like Sandwich station, 2.8 miles to the east of Ash, trade from early, so work is timed around them.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Report cracked or peeling sealant early
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Have extract fans checked so wet areas dry out
  • Add sealant to the planned maintenance inspection list

Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just give us a call on 01277 525 020 or send photos by email for a quote.

Sealant rarely fails all at once across a building. A few splits this year typically mean more next year. We’ll tell you which sealant joints need doing first and which can wait.
