Business units in the countryside around places like Aston End are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What Aston End’s businesses ask us to seal

The planned town of Stevenage is on Aston End’s doorstep. Commercial buildings from the planned-town decades tend to carry joints from several refits, not all of them matching. At about 28 miles from central London, Aston End is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.

If you run an office at a site such as Astonbury Farm & Business Park, 1.2 miles to the south of Aston End, the sealant at reception desks, tea points and frames ages with each fit-out. Shops and cafés around stations like Stevenage station (to the west of Aston End) trade from early, so work is timed around them. Occupiers with premises at both Astonbury Farm & Business Park and Monkswood Retail Park could have the sealant at each handled under one quote.

Aston End is about 1 mile east of Stevenage, in Hertfordshire. Across the SG2 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hertfordshire coverage takes in 371 places. Our London page has more on work in that area (28 miles or so).

If you need commercial sealant contractors in SG2, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. We also cover Chells (1 mile north-west), Stevenage (1 mile west), Walkern (2 miles north-east), Bedwell (2 miles west) and Pin Green (2 miles north-west) for sealant joints. Further afield, our area takes in St Albans (13 miles south-west), Bishop's Stortford (13 miles east), Welwyn Garden City (7 miles south), Harpenden (10 miles south-west), Hitchin (6 miles north-west) and Hoddesdon (12 miles south-east).

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Surfaces we seal

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

Questions about Aston End

Is Astonbury Farm & Business Park, near Aston End, within your area?

Yes. Estates, retail parks and business parks around Aston End, Astonbury Farm & Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Is Aston End too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.

Can you handle sealant work across several sites?

Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

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.

Why act early in Aston End

It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Converted and older buildings near places like Aston End tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

What you get with us

  • Standard and matched colours in many product ranges
  • Health and safety: CHAS accredited

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Aston End 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. You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

Related advice

After the work

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Report cracked or peeling sealant early
  • Keep washroom and kitchen extraction working
  • Keep barriers up until the new sealant has cured
  • Brief cleaning contractors to avoid scourers and blades on sealant

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life.

In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to.

Surface by surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we will say so before sealing.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
