Sealant specialists in Itchen Stoke

We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve gaps behind commercial kitchen worktops and sinks and smeared sealant across finishes from a rushed job, on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Itchen Stoke it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

We price commercial jobs in Itchen Stoke from photos, drawings or a site visit, and the scope is set out in writing.

Rural business units near smaller places such as Itchen Stoke 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Itchen Stoke

A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.

Look out for the following:

  • Untidy joints in a reception, shop floor or lobby
  • Layers of sealant, all of them failing
  • Leaks that seem to come through a sealant line
  • Sanitary sealant that has gone black and patchy

A lasting commercial joint around Itchen Stoke begins with the old bead fully out and the faces clean and dry.

Before you book anyone

  • Proof of insurance
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • What site paperwork they can supply

Choosing a commercial sealant contractor

Your questions answered

Does your area include sites such as Abbas Business Centre, near Itchen Stoke?

Yes, sites like Abbas Business Centre are within our area, along with the rest of Itchen Stoke. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is a smaller place like Itchen Stoke outside your area?

No. Places such as Itchen Stoke are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Which site documents can you send us?

Let us know your requirements when you ask for a price. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

What about asbestos in old mastic?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Keep a record of which joints were resealed and when
  • Check joints after other trades have worked nearby
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Report cracked or peeling sealant early

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth. Leaving the area closed until then keeps the bead neat.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We will tell you which sealant joints need doing first and which can wait.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For work around Itchen Stoke, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Send any specification or drawings in advance

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Work for main contractors and building owners

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Joints and surfaces we work on

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

Surface by surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it, and tell you if the edges need repairing first.

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price.
