Common questions from St Leonards clients
Will you take on work at estates like Ashley Heath Industrial Estate, close to St Leonards?
Yes. We cover St Leonards and the area around it, including industrial estates, business parks and retail parks such as Ashley Heath Industrial Estate. Photos and a short description are enough for a first look.
Can work at a site such as Sheiling College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you replace failed glazing units?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Facade sealing in St Leonards
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. If you have leaks at window and door perimeters and old perimeter mastic that has dried out, we can put it right, whatever the surface. Searching for sealant specialists in St Leonards? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a contractor on a smaller site near St Leonards, one mastic visit at the right stage saves return trips. Let us know the key stages and we will time the work so nothing waits on us.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When to call us in St Leonards
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Any of the following is a good reason to get the joints checked over:
- Old perimeter mastic that has dried out
- Leaks at window and door perimeters
- Facade joints cracked through the middle
- Discoloured or dirty facade joints
Hotel extensions and refits, at places such as St Leonards Hotel (under half a mile east of St Leonards), typically run between busy periods, so the sealing is squeezed into short windows.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
- Can the work be phased to keep areas open?
Keeping the joints sound
A few simple habits keep the new joints working:
- Keep sills, gutters and drainage paths clear
- Insist on a full cut-out when joints are renewed
- Note when each elevation was last resealed
- Avoid harsh cleaners on facade sealant
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
Facade sealing in St Leonards: the local picture
St Leonards is in the South East, one of the UK’s drier regions. 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. A 2-mile radius around St Leonards takes in several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Recladding or extending a unit at a site like Ashley Heath Industrial Estate, 1.4 miles north-west of St Leonards, brings panel joints and frame perimeters into the programme. Hospital estates such as St Leonards Hospital, 0.9 miles to the south-west of St Leonards, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

What happens if it’s left?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

For a job in St Leonards, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
