About our commercial sealant contractors in South Ascot

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in South Ascot, speak to us on 01277 525 020 or email a schedule or drawings with the site addresses. We work on external facade joints, movement joints in walls and floors and kitchen worktops and splashbacks, and the failures we are asked to look at most are gaps behind commercial kitchen worktops and sinks and movement joints packed with grit and debris. Facilities teams, main contractors and managing agents in South Ascot tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

In a smaller place such as South Ascot, commercial buildings are normally a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in South Ascot can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Old mastic that tests positive for asbestos
  • Water from a services leak rather than a joint
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Surfaces we seal

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

Our process

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Several jobs near South Ascot can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  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. We hand back each area with its cure time and our 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Your questions answered

Is a smaller place like South Ascot outside your area?

No. Places such as South Ascot are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you cover business parks and estates near South Ascot, such as Ascot Business Park?

Yes, sites like Ascot Business Park are within our area, along with the rest of South Ascot. Send details of the unit and the work through our quote form for a quick quote.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Is failed sealant stripped out, or sealed over?

Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Different surfaces, different methods

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.

When to bring in a specialist

Some joints are best left to specialists: 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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Common problems we fix in South Ascot

Every sealant joint is a maintenance item. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once, so periodic inspection matters more than any date on a schedule.

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

  • Earlier reseals applied straight onto the failed bead
  • Untidy joints in a reception, shop floor or lobby
  • Leaks that seem to come through a sealant line
  • Mouldy silicone around WCs, urinals and vanity tops

A hotel such as Macdonald Berystede Hotel & Spa (to the south-east of South Ascot) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Questions to ask before you book

  • How the existing material will be dealt with
  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed
