Your questions answered
Is Station Road Industrial Estate, near Heathfield, within your area?
Yes, sites like Station Road Industrial Estate are within our area, along with the rest of Heathfield. 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 Hellingly Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
From enquiry to sign-off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. Several jobs near Heathfield can be grouped on one trip. Tell us your site hours and we will plan around them.
- We start with photographs, 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 goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
- Send any specification or drawings in advance

Looking after the joints
After handover, a little attention goes a long way:
- Keep the sealant details on the building file
- Share access with other external trades
- Check the asbestos register before old mastic is disturbed
- Investigate damp beside windows promptly
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Render or concrete edges that have broken away
- Work on the window or framing system itself
If in doubt, ring 01277 525 020 or email the details over and we will say what we think.
What we seal
- Stone and brick facade joints
- Shopfront frames
- Cladding panel joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Coping and flashing joints
Facades, frames and programmes in Heathfield
Heathfield lies roughly 40 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Heathfield 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.
When units on a site such as Station Road Industrial Estate, under half a mile to the north-west of Heathfield, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as Parkside Community Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

When to call us in Heathfield
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
These are often picked up first by site or facilities staff:
- Unsightly perimeter sealant on a visible elevation
- Draughts around frames and panels
- Failed sealant on precast panel joints
- Leaks at window and door perimeters
Extensions at sites like Hellingly Hospital, 5.3 miles south of Heathfield, typically sit beside working departments, and the mastic follows strict access rules.

Different surfaces, different methods
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.
