How we handle facade sealing in Marley

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on coping and flashing joints, stone and brick facade joints and shopfront frames, and what we’re called in for most is cladding panel joints that have opened up and facade joints cracked through the middle. One point of contact handles commercial sealant work in Marley from the first photos to the final walk-round, for single jobs and planned programmes alike.

Around smaller places like Marley, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Common questions from Marley clients

Is Marley too far out for you?

Not at all. Marley is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can work at a site such as Canterbury Christ Church University fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Which sealant do you use on facades?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long does a typical visit take?

It depends on the scope, but the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we will set out a timescale with the quote.

Common problems we fix in Marley

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Things that typically lead to an enquiry:

  • New sealant peeling off old mastic
  • Sealant pulling away from frames or panels
  • Damp patches beside frames after rain
  • Failed sealant on precast panel joints

Building work at universities like Canterbury Christ Church University (to the north of Marley) is often timed for the summer, mastic included.

Comparing quotes

  • How the existing material will be dealt with
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Leave it or put it right?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Converted and older buildings near places like Marley tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

New build and refits around Marley

Marley is about 38 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Marley included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Units on estates such as Roebuck Business Park (to the west of Marley) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Historic houses such as Leeds Castle (to the west of Marley) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Marley is about 7 miles east of Maidstone, in Kent. Any commercial site in Marley is covered, whether it’s a single job or part of a planned programme. 931 places across Kent fall within our area, Marley among them. For work in that direction, see our London page (38 miles or so).

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Marley need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows
  • Arrange parking or a loading space

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Installing or repairing glazing systems
  • Joints whose design needs changing by the specifier
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think before you book.
