Facade sealing in Great Leighs
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. The enquiries we see most involve new sealant peeling off old mastic and air leaks through failed facade joints, across window and door perimeters, cladding panel joints and stone and brick facade joints. A specialist sealant contractor works differently from a general builder: in Great Leighs, that means joint design, primers and backing rod as standard.
Around smaller places like Great Leighs, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Building owners, agents and FMs in Great Leighs
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Confirm the survey covers external sealants in older buildings
- Keep the sealant details on the building file
- Report water ingress at frames as soon as it shows
- Keep sills, gutters and drainage paths clear
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Damaged frames that need replacing
- Providing access systems for the work
- Joints too narrow for the movement they take, which need redesign
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

When to call us in Great Leighs
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Most enquiries start with something like this:
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Water coming in around window frames
- Unsightly perimeter sealant on a visible elevation
New wings at hospitals like William Julien Courtauld Hospital, 3.6 miles to the north-east of Great Leighs, bring long runs of window and panel joints to seal.
What your quote should include
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?

Your questions answered
Is hospital work, at somewhere like William Julien Courtauld Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Great Leighs off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Diagnose, treat, sign off

Facade sealing in Great Leighs: the local picture
Central London is about 34 miles from Great Leighs. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Great Leighs included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
For contractors at a school such as Great Leighs Primary School, sealing has to be finished before term starts. For contractors refurbishing units at places like Banters Lane Business Park (0.6 miles north-east of Great Leighs), the mastic covers cladding panels, roller-door and window perimeters.
