Photos, a specification or a quick description of the joints is enough to start a fixed quote.
For managing agents and facilities managers
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Walmer can form part of a wider programme across Kent.
Mastic sealing for commercial buildings in Walmer
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you have the same joint failures repeated across a portfolio and draught complaints from residents or tenants, we can help, on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells alike. Whoever orders the work in Walmer, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
In a smaller place such as Walmer, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Why it’s worth doing now in Walmer
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. In a smaller place such as Walmer, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact.

How the job changes by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
Your questions answered
We manage a building near Walmer station. Can you help?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Does a coastal location like Walmer affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
What we seal
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells

With historic buildings such as Walmer Castle (0.3 miles south-east of Walmer) in the wider area, owners of older properties around Walmer should expect mastic to need a product that suits old masonry.

Schools and community buildings such as The Downs Church of England Primary School need frame and external mastic kept sound like any building.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
- Log resealing dates block by block
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
