Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Around Hever, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Why appoint us
- Constructionline member for supplier checks
- A range of standard colours, depending on the product
- Failed material removed, not covered up
- Fully insured, including public liability cover

About our mastic sealing in Hever
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you have estate-wide sealant that is simply worn out and draughts at frames across a block, we can help, whatever the surface. One point of contact handles commercial sealant work in Hever from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Hever, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Your fixed quote is built from the real scope. It allows for:
- Travel to remote or island sites
- Working within restricted access windows
- How much existing material needs removing
- The site’s rules and procedures
Pricing mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- Clear photographs of the problem areas
- Access details, including height
- The postcode of the building
- The asbestos register, for older buildings
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
FAQs: Hever
Will you take on a block within reach of Hever station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Can one quote cover a number of our buildings near Hever?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How long will the new sealant last?
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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Hever need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

Advice
Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Asbestos-containing sealant, which we don’t remove
- Leaks through the frame itself rather than the perimeter
- Broken glass or failed sealed units
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Surfaces we seal
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
For owners and agents in Hever
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 23 miles from central London, Hever is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Churches, halls and community buildings such as Church of St Peter are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Schools and community buildings such as Hever Church of England Voluntary Aided Primary School need frame and external mastic kept sound like any building. If you look after a block within reach of Hever station, 0.5 miles west of Hever, frame and balcony mastic can be renewed on one programme.
