Questions we are asked in St Leonards
Can being near the sea in St Leonards affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do hotels near St Leonards have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Commercial sealant contractors in St Leonards, done properly
Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. If you are dealing with sanitary sealant that has gone black and patchy and untidy joints in a reception, shop floor or lobby, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in St Leonards it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
The most common commercial job in St Leonards is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
In a town the size of St Leonards, commercial buildings tend to be high-street shops, offices over shops, schools, care homes and small industrial units. Each has joints that wear: frontages, staff kitchens, washrooms and window perimeters, and where a frontage is on show, a matched colour keeps it looking right.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What sets the cost
Each job is priced on its own details. The main factors are:
- How accessible the joints are
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Working within restricted access windows
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- The product your specification calls for
- Whether the building will be occupied during the work

Different surfaces, different methods
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Shops, offices and hotels in and around St Leonards
St Leonards is within about 1 mile of the coast. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are normally where failed joints show first. St Leonards has six care or nursing homes no more than 2 miles away. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean; colours can be chosen to suit the interior.
For a retailer at a site such as Bexhill Road Retail Park, 0.7 miles to the west of St Leonards, the joints customers see are as much part of the fit-out as the shelving. Premises within reach of St Leonards Warrior Square station, less than half a mile east of St Leonards, often have busy frontages where joints are seen by everyone passing. In hotels such as OYO Eagle House Hotel, under half a mile east of St Leonards, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Keeping the joints sound
Once the work is signed off, these steps help:
- Note dates and locations of sealant work for future planning
- Keep washroom and kitchen extraction working
- Report cracked or peeling sealant early
- Keep abrasive pads and scrapers off resealed joints
Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just ring 01277 525 020 or email the details over for a quote.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a town like St Leonards, we try to group jobs for the same client into one visit. Tell us when the building is open and we will plan to suit.
- First, details come to us: photographs, drawings or a schedule of the areas.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Send any specification or drawings in advance
- Move anything stored against the joints
