What happens if it’s left?
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

About our facade sealing in Walmer
Managing agents and owners in Walmer ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. Most enquiries involve cold air coming in at window perimeters and staining on stone next to old sealant, on window and door perimeters, cladding panel joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: on jobs in Walmer, preparation and product choice get the time they need.
Around places like Walmer, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or use the quote form and we will come back to it.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Inspect facade joints on a regular cycle
- Insist on a full cut-out when joints are renewed
- Keep pressure washers away from fresh sealant
- Check the asbestos register before old mastic is disturbed
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
Questions we’re asked in Walmer
Is Walmer off your patch?
Not at all. Walmer is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Does the sea air around Walmer change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you seal facades in winter?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things as the work goes on.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Can staff carry on working while you are here?
Usually, yes. We phase the work so most of the building stays in use.
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. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Facade sealing in Walmer: the local picture
Walmer sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Walmer 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.
School extensions, at buildings such as The Downs Church of England Primary School, usually run to the summer holidays, mastic included. Historic houses such as Walmer Castle, 0.3 miles to the south-east of Walmer, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Extensions at sites like Victoria Hospital, 1.1 miles to the north of Walmer, typically sit beside working departments, and the mastic follows strict access rules.

Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. If neighbouring businesses or buildings around Walmer need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Let us know about inductions and permits
- Make sure the joints can be reached
- Tell us which areas need to stay in use

Related advice
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Different surfaces, different methods
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, and mask the edges carefully.
Commercial clients in Walmer
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
If you look after buildings for someone else, 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.
