Mastic sealing in Ashurst
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you have window mastic that has split and shrunk and estate-wide sealant that is simply worn out, we can help, on shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ashurst, that means joint design, primers and backing rod as standard.
Rural conversions near places like Ashurst often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
What sets the cost
Before we quote, we look at:
- Induction, permit and paperwork requirements
- Any access equipment needed
- Which sealant the job calls for
- Quantities, in metres or numbers
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.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Clear photos of the problem areas
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- Any dates the work must fit around
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes and those cost far more to put right. Older rural buildings around Ashurst move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Specification-led, product-correct work

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Materials that need asbestos testing before work
- Failed window or door frames, which need a window contractor
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly.
What we seal
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
Common problems we fix in Ashurst
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant, so these repairs rarely last.
Any of the following is a good reason to get the joints checked over:
- Window mastic that has split and shrunk
- Damp patches beside frames
- The same joint failures repeated across a portfolio
- Movement joints with sealant missing
Trustees of buildings like Church of St Martin of Tours can bring frame and external mastic into a planned maintenance list.
What your quote should include
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
- Their public liability cover

Frames, entrances and external joints in Ashurst
Ashurst is about 28 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Ashurst is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For agents with blocks near Ashurst Kent station, which lies west of Ashurst, a block-wide mastic programme deals with frames, balconies and entrances in one go. With historic buildings such as Groombridge Place (to the south-east of Ashurst) in the wider area, owners of older properties around Ashurst should expect mastic to need a product that suits old masonry.

Questions about Ashurst
Is Ashurst off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you cover business parks and estates near Ashurst, such as Speldhurst Business Park?
Yes, sites like Speldhurst Business Park are within our area, along with the rest of Ashurst. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
