Commercial sealant contractors for commercial buildings in Aylesham

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. If you have water staining near frames, panels or ceilings and frame sealant that has cracked, shrunk or pulled away, we can help, on window and door perimeters, kitchen worktops and splashbacks and washrooms and tea points alike. One point of contact handles commercial sealant work in Aylesham from the first photos to the final walk-round, for single jobs and planned programmes alike.

In an occupied building in Aylesham, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Places like Aylesham 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.

Whoever the client is, the cover is the same: 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.

Cost factors for sealant joints

What shapes the price:

  • The product specified
  • Phasing around occupants
  • How much existing material needs removing
  • Induction, permit and paperwork requirements

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • A wide shot and a close-up of the area
  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email the details over.

Commercial clients in Aylesham

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Faulty windows rather than failed perimeter sealant
  • Roof leaks that only look like a joint problem
  • Leaks from pipework, wastes or valves (that’s plumbing)

Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

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

Shops, offices and hotels in and around Aylesham

Aylesham is about 59 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings. Aylesham has at least three named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it.

If you run a unit on an estate such as Aylesham Industrial Estate, 0.5 miles to the south-west of Aylesham, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. If you have premises on more than one site, say at Aylesham Industrial Estate and CT3 Business Park, one contractor and one quote can cover both. For premises near Aylesham station, under half a mile east of Aylesham, footfall is part of the plan: work is phased so shops and offices keep trading.

Aylesham is about 6 miles south-east of Canterbury, in Kent. We cover commercial sites throughout Aylesham. Aylesham is one of 931 places in Kent on our list. London is covered too, around 59 miles from Aylesham.

Postcode districts covered here: CT3 for sealant joints. Buildings on Market Place, Mexborough Square and Derwent Way are within our area for sealant joints. Nearby places we also cover include Bloodden (1 mile north), Adisham (1 mile north), Womenswold (1 mile south-west), Woolage Green (2 miles south) and Out Elmstead (2 miles south-west). A short drive away, we cover Canterbury (6 miles north-west), Margate (13 miles north-east), Dover (8 miles south-east), Folkestone (10 miles south), Ramsgate (12 miles north-east) and Broadstairs (14 miles north-east).

Why deal with it now?

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings, and they’re where most failures begin. You notice the difference years later, not on the day. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: 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. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. What matters most for a job in Aylesham is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  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. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  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

  • Share your working hours and any access restrictions
  • Explain the parking and delivery arrangements
  • Tell us which areas need to stay in use

Common questions from Aylesham clients

Is Aylesham too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Will the building have to shut during the work?

It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.

What site paperwork can you provide?

We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
