About our mastic sealing in West Green
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you’re dealing with open joints in brickwork or panels and estate-wide sealant that is simply worn out, we can help. Searching for sealant specialists in West Green? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Owners with buildings around smaller places like West Green often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What we are called out for in West Green
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
If one of these sounds familiar, it’s time for a closer look:
- Occupiers reporting cold air round windows
- Mastic failing across several blocks on an estate
- Complaints coming in block by block
- Water getting in round frames after rain
If your remit includes a building such as West Green Primary School, frame and door mastic can be programmed for the holidays.

What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- Travel to remote or island sites
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Anything awkward about access or site hours
- The type of building and who uses it
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.
Questions about West Green
Is West Green off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you work for managing agents with blocks near Crawley station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Aftercare for building managers
To get the most from the new sealant:
- Include mastic in your cyclical inspections
- Keep bins and bikes away from communal door frames
- Prioritise elevations facing the weather
- Share the asbestos register when you send details
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

- Broken glass or failed sealed units
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Blocks and managed buildings in West Green
Crawley, one of the planned towns of the twentieth century, takes in or adjoins West Green. Blocks and estates went up in phases, so frames and external joints of the same age tend to give out together. Rainfall across the South East, West Green included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Buildings close to stations like Crawley station (0.8 miles south of West Green) are often flats over shops, with frame mastic to keep sound. Older community buildings, Voice of Deliverance Full Gospel Church of God among them, often have frames of mixed ages whose mastic varies.
