When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Misted or failed double-glazed units
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

How we handle mastic sealing in Kilnwood Vale
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are old repairs sealed over failed mastic and the same joint failures repeated across a portfolio. Most enquiries from Kilnwood Vale start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For buildings around smaller places like Kilnwood Vale, we group work so one trip covers it. Photos of each elevation help us quote accurately.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Block-wide mastic in Kilnwood Vale
Rainfall across the South East, Kilnwood Vale included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Kilnwood Vale lies roughly 28 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
Property owners at sites such as Holmbush Potteries Industrial Estate (under half a mile south-east of Kilnwood Vale) can have mastic renewed between lettings. Site managers at schools like The Bewbush Academy can fit frame mastic into the summer works. For agents with blocks near Faygate station, 0.9 miles to the west of Kilnwood Vale, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Kilnwood Vale is about 1 mile south-west of Bewbush, in West Sussex.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Reduce knocks to communal area joints
- Have the asbestos survey to hand for older buildings
- Encourage occupiers to report problems at frames
- Include mastic in your cyclical inspections
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Quoting for work in Kilnwood Vale
What shapes the price:
- Joint width, depth and condition
- Travel to remote or island sites
- Which sealant the job calls for
- Whether the work must be split into stages
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:

- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- When you need the work done

What the job involves on each surface
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Your questions answered
Is Kilnwood Vale too far out for you?
No. Places such as Kilnwood Vale are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Holmbush Potteries Industrial Estate, by Kilnwood Vale?
Yes. Estates, retail parks and business parks around Kilnwood Vale, Holmbush Potteries Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order starting wherever is most urgent.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. 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.
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.
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. For a building around Kilnwood Vale, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Have the specification and drawings to hand
- Make sure the joints can be reached

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
