Commercial sealant contractors for commercial buildings in Thorley Street

Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. Part of the job is telling you when the fix is something other than sealant, so nobody pays for a reseal that can’t hold. If you have wall and floor joints that have lost their seal and sanitary sealant that has gone black and patchy, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Thorley Street it comes down to the same thing: the right product in a properly prepared joint.

On a typical commercial building in Thorley Street, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

A job in a smaller place like Thorley Street is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Do you need commercial sealant contractors in Thorley Street?

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

These are often picked up first by site or facilities staff:

  • Sanitary sealant that has gone black and patchy
  • Leaks that seem to come through a sealant line
  • Wall and floor joints that have lost their seal
  • Earlier reseals applied straight onto the failed bead

Whatever the building in Thorley Street, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Before you book anyone

  • How the existing material will be dealt with
  • How they’ll work around occupants
  • Will CSCS-carded applicators be on site?
  • Health and safety accreditation such as CHAS

Choosing a commercial sealant contractor

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A dripping trap, valve or pipe behind a fitting
  • Faulty windows rather than failed perimeter sealant
  • Cracking that needs a structural engineer to look at it

If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.

Joints and surfaces we work on

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

Your questions answered

Do hotels near Thorley Street have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Can being near the sea in Thorley Street affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Will the building have to shut during the work?

That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we will work around it.

Could the old sealant in an older building contain asbestos?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How the job changes by surface

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We’ll recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

What Thorley Street’s businesses ask us to seal

Thorley Street sits close to the coast, within about 2 miles. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. We choose a product rated for the exposure, then confirm the colours available for it. The area within 2 miles of Thorley Street holds a number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, and the work can be phased so the rest of the hotel keeps trading.

Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.

Leave it or put it right?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement. Around Thorley Street, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why appoint us

  • Colour agreed before work starts
  • Colours chosen to suit frames, cladding or finishes where possible
  • Work carried out by CSCS-carded applicators
  • Joints cleaned back to sound surfaces
