When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Commercial mastic work in Barnes Street

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. 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 window and door perimeter joints that have cracked open and external beads that have gone brittle and cracked, we can put it right. Whoever orders the work in Barnes Street, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

The most common commercial job in Barnes Street is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Rural business units near smaller places such as Barnes Street 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for sealant joints

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Distance, for remote addresses
  • The site’s rules and procedures
  • The total length or number of joints
  • Access and working height

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. For a building around Barnes Street, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Getting the site ready

  • Point out any areas we must not close
  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Roof leaks that only look like a joint problem
  • A dripping trap, valve or pipe behind a fitting
  • Walls or slabs moving more than any sealant can take

If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

What we seal

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

Sealant on show in Barnes Street’s commercial buildings

Barnes Street is about 28 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. If you have premises across the region, one contractor can cover them all. Barnes Street is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Sites a few miles apart, such as Forstal Business Park and Eldon Way Industrial Estate, can share one programme and one point of contact. For premises near Beltring station, 2.2 miles east of Barnes Street, footfall is part of the plan: work is phased so shops and offices keep trading. If you run an office at a site such as Forstal Business Park, 2 miles to the south-east of Barnes Street, the sealant at reception desks, tea points and frames ages with each fit-out.

FAQs: Barnes Street

Is Barnes Street off your patch?

No. Small places get the same service as large ones. 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.

Can you match sealant colours for premises in Barnes Street?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photos and we’ll confirm what’s available for the product.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How soon can the area be used again?

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.

Does commercial sealant work come with a guarantee?

Our workmanship on each job is backed by a 12-month guarantee. Public liability insurance is in place too.

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing, until its cure time has passed.

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.

What happens if it’s left?

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. Around Barnes Street, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Deal with small splits before they become leaks
  • Check sealant as part of routine building inspections
  • Keep abrasive pads and scrapers off resealed joints
  • Check joints after other trades have worked nearby

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 ring 01277 525 020 or send photos by email for a quote.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
