About our commercial sealant contractors in Marlpit Hill

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. If you have frame sealant that has cracked, shrunk or pulled away and expansion joints with the sealant torn out, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Marlpit Hill, that means joint design, primers and backing rod as standard.

The most common commercial job in Marlpit Hill is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Commercial sealant work around smaller places like Marlpit Hill tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Different surfaces, different methods

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few hours for one area, or a planned series of visits across a bigger building, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Marlpit Hill are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Before we start on site

  • Move anything stored against the joints
  • Let building users know which areas are affected
  • Confirm the product named in the specification

Marlpit Hill is about 21 miles from central London. The commuter belt holds a great many offices, retail parks and business parks.

Maintenance after handover

A few simple habits keep the new joints working:

  • Look at the sealant around anything that has been moved or replaced
  • Act on the first lifting edges rather than waiting
  • Log reseals in the O&M or maintenance records
  • Don’t let cleaning or traffic back on before the cure time is up

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can give us a call on 01277 525 020 or send photos by email and send a picture.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Questions about Marlpit Hill

What paperwork can you provide for a job in Marlpit Hill?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is a smaller place like Marlpit Hill outside your area?

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

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

What guarantee do you give on resealing?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What we’re called out for in Marlpit Hill

Washrooms and kitchens wear sealant out in their own way. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.

Any of the following is a good reason to get the joints checked over:

  • Earlier reseals applied straight onto the failed bead
  • Frame sealant that has cracked, shrunk or pulled away
  • Smeared sealant across finishes from a rushed job
  • Damp patches where an external joint has failed

Offices and shops close to stations such as Edenbridge station, less than half a mile to the south-west of Marlpit Hill, tend to be busy all day, so sealant work is planned around opening hours.

What your quote should include

  • What the guarantee covers, and for how long
  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed
