Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Curteis' Corner, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in

Mastic sealing in Curteis' Corner, done properly

Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Site teams most often ask us about draught complaints from residents or tenants and damp patches beside frames, on window and door perimeters on blocks, balcony and threshold joints and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Curteis' Corner it comes down to the same thing: the right product in a properly prepared joint.

For owners with a single building near Curteis' Corner, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

Why it’s worth doing now in Curteis' Corner

Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Converted and older buildings near places like Curteis' Corner tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us

  • Health and safety: CHAS accredited
  • One phone line for London, the South East and Scotland
  • Sealing commercial buildings since 2005
  • Work to your specification and the manufacturer’s guidance

Read our cost guide or our accreditations.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Blocks and managed buildings in Curteis' Corner

Central London is about 41 miles from Curteis' Corner. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Curteis' Corner is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

If you’re responsible for a building such as Parish Church of All Saints, frame and door mastic needs the same attention as any other property. For agents with blocks near Headcorn station (2.9 miles north of Curteis' Corner), a block-wide mastic programme deals with frames, balconies and entrances in one go. If your remit includes a building such as John Mayne Church of England Primary School, frame and door mastic can be programmed for the holidays.

Questions about Curteis' Corner

Is Curteis' Corner off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

We manage a building near Headcorn station. Can you help?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Will residents or tenants be disturbed?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Substrate edges that need repairing first
  • Asbestos-containing sealant, which we don’t remove
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

What we seal

  • External wall and movement joints
  • Window and door perimeters on blocks
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms

What sets the cost

Before we quote, we look at:

  • Removal of failed or old sealant
  • The size and state of each joint
  • Quantities, in metres or numbers
  • Which sealant the job calls for

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • The site address and postcode
  • Access details, including height
  • Photos of the joints, close up and from further back

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or send details through our quote form with what you know.
