Alkerton: questions and answers

Is Alkerton too far out for you?

No. Places such as Alkerton are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Alkerton Oaks Business Park, close to Alkerton?

Yes. Our area takes in Alkerton and its surroundings, with estates and business parks such as Alkerton Oaks Business Park included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can you handle sealant work across several sites?

Yes. We regularly take on multi-site work and planned maintenance programmes, quoted per building or as a package.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member.

How is commercial sealant work priced?

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.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Commercial sealant contractors in Alkerton, done properly

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, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Most enquiries involve untidy joints in a reception, shop floor or lobby and window and door perimeter joints that have cracked open, on floor and threshold joints, window and door perimeters and external facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Alkerton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

The most common commercial job in Alkerton is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Commercial sealant work around smaller places like Alkerton tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Suspect materials that need testing and specialist removal
  • A dripping trap, valve or pipe behind a fitting
  • Broken glass or blown double-glazed units

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Joints and surfaces we work on

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

Looking after the joints

After handover, these steps help:

  • Act on the first lifting edges rather than waiting
  • Don’t let cleaning or traffic back on before the cure time is up
  • On pre-2000 buildings, share the asbestos information before work starts
  • Note dates and locations of sealant work for future planning

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, ring 01277 525 020 or use the quote form with a photo.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.

Building owners, agents and FMs in Alkerton

We work for building owners and managing agents on everything from one building to a spread of sites around Alkerton. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

How the job changes by surface

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal.

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. Colour options are confirmed with the quote.

What we’re called out for in Alkerton

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. Once it stiffens, the joint opens up at the next big temperature swing.

Site and facilities staff are often the first to spot these:

  • A top-up bead over failed sealant, now lifting
  • Shrunken sealant along kitchen worktops and splashbacks
  • Movement joints packed with grit and debris
  • Weathered facade sealant that no longer flexes

Parks like Alkerton Oaks Business Park (to the north of Alkerton) see tenants come and go, and every move-in brings joints to seal.
