About our facade sealing in Mark Cross
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you have failed sealant on precast panel joints and hard, chalky sealant that no longer flexes, we can help, whatever the surface. Whoever orders the work in Mark Cross, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
For a site near Mark Cross, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Cracked or spalling substrates that need repair before sealing
- Installing or repairing glazing systems

Your questions answered
Does your area include sites such as Millbrook Industrial Estate, near Mark Cross?
Yes, sites like Millbrook Industrial Estate are within our area, along with the rest of Mark Cross. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Crowborough War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How long does a typical visit take?
It depends on the scope, though a typical visit typically 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.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Mark Cross are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Getting the site ready
- Let us know about inductions and permits
- Send your site hours and access windows
- Explain the parking and delivery arrangements

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Signs you need facade sealing in Mark Cross
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
What tends to prompt an enquiry:
- New sealant peeling off old mastic
- Old perimeter mastic that has dried out
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
Historic houses such as Wadhurst Castle, 3.2 miles to the east of Mark Cross, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
What to look for in a quote
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- How long is the guarantee, and what does it include?

What else we do in Mark Cross
Keeping the joints sound
A few simple habits keep the new joints working:
- Inspect facade joints on a regular cycle
- Keep sills, gutters and drainage paths clear
- Avoid patch repairs on failed facade joints
- Note when each elevation was last resealed
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
What happens if it’s left?
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Around Mark Cross, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What you get with us

- Commercial sealant work since 2005

New build and refits around Mark Cross
Rainfall across the South East, Mark Cross included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. At about 34 miles from central London, Mark Cross is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
New wings at hospitals like Crowborough War Memorial Hospital, 4.4 miles west of Mark Cross, bring long runs of window and panel joints to seal. School extensions, at buildings such as Mark Cross Church of England Aided Primary School, typically run to the summer holidays, mastic included.
